The sound remains the same

Yamaha has built its reputation on great sound. As they continue to pack more features into their home theater receivers, the great sound they're known for remains a constant. That's what their AVENTAGE-series receivers are all about. The RX-A840 will add excitement and drama to your home theater while making it easier than ever to enjoy a wide range of entertainment. Think far beyond Blu-ray discs and CDs. The 'A840 is made to bring your smartphone, tablet, and computer into your home theater while making everything from MP3s to online videos sound and look their best.

Wi-Fi offers a wide range of wireless music options

If you've never connected a receiver to your wireless home network, you may not realize how much music you're missing out on. Built-in Wi-Fi makes the RX-A840 a snap to integrate with your network. Once you're connected, you can listen to free Pandora® Internet radio as well as free radio streams from hundreds of stations around the world. If you're a subscriber to Spotify®, SiriusXM, or Rhapsody, you can enjoy their seemingly endless music choices. Got a computer or networked hard drive loaded with music? DLNA compatibility allows this receiver to tap into your collection wirelessly, so you never have to touch another CD again. Finally, if you're an Apple® user, AirPlay lets you listen wirelessly from your iPhone®, iPad®, iPod touch®, or a computer running iTunes®.

Stream music wirelessly to the RX-A840 with Yamaha's free AV Controller app for Apple and Android devices.

Take home theater into the next room

One of the benefits of the 'A840's seven-channel amplifier is powering speakers in multiple rooms. There are a total of nine speaker outputs on this receiver. That means you can connect a 7.2-channel system in your home theater and still have two more speaker outputs left over. The receiver can automatically reassign the back surround channels to Zone 2 speakers. The family can enjoy a movie in 5.1-channel surround sound in the home theater while you listen to your digital music library out on the deck. Or, activate Party Mode to play the same song in both zones. There's also a second HDMI output. This is perfect for adding a TV to the kitchen, so you don't have to miss a second of the game just because you need a refill.

Easy control with your smartphone or tablet

What's the best way to control this receiver's many features? Download the free Yamaha AV Controller app to your smartphone or tablet. Available for Apple or Android™, the app offers easy touchscreen control of the receiver's most critical functions — from switching sources and controlling the volume, to multi-zone playback control and selecting an Internet radio station.

Built on sound principles

Excellent sound quality is the guiding principle behind Yamaha's AVENTAGE receivers. Low-jitter PLL circuitry reduces timing jitter from digital sources, for accurate playback and precise stereo imaging. The aluminum front panel and extra center foot on the receiver's base help to further eliminate unwanted resonance and distortion. And the high-quality Burr-Brown digital-to-analog converters decode the latest audio formats with accuracy and detail, so digital sources like Blu-ray discs and high-resolution music files sound their best.

Don't forget about picture quality

Great-sound is only part of the AVENTAGE RX-A840's story. Video upconversion can take analog or HDMI-connected sources as high as 4K for display on Ultra HD TVs. If you haven't yet taken the 4K plunge, you can also choose upscaling to 1080p HD to make old DVDs glisten with new life on your TV. There's also an extra HDMI input on the front panel. Connect a camera or camcorder, or a smartphone or tablet with Mobile High-Definition Link (MHL) compatibility. This allows you to share music, videos, or photos through your home theater with stunning picture quality and rich, full sound.

    Crutchfield Customer Review (What's this?)

    We have had our new receiver for about 2 weeks now and it was a replacement for one that we had only had for 4 years. We have been very impressed with the Yamaha. Very easy to set up and my husband loved that it wasn't big and bulky like our previous one. We also set it up with our universal remote this weekend and it was so easy to do.

    Crutchfield Customer Review (What's this?)

    I thought my Onkyo system was pretty good. we never had a problem with it and the sound was always clear and entertaining. The radio receiver had failed and i had been using a FM receiver dongle to get music off the air etc. I also had an input hooked up to my TV so i was able to get music streamed through that avenue. Our speakers are the tiny Bose with a subwoofer mounted on the balcony. For surround we have two 4 feet tall massive speakers also on teh balcony overlooking the living room. We had some structural adjustments to make on our house and so after lots of stuff was done over 6 months or so, i decided to treat myself to a new stereo. system. without any speaker changes, the difference is unbelievable. I have not sat in a chair and simply enjoyed the music (without multi-tasking) in years. My wife and i did just that for three evening straight, It sounds so great we are thinking about going to Colorado to pick up some enhancer.... :-)

    Pros: Rich, full, non distorted and great phone support while setting it up. I spoke to two different techs and both were able to understand my dilemma quickly and never wasted my time with inane or repetitive questions.

    Cons: Not a darn thing!

    justin from Brooklyn, NY on 6/30/2016

    Crutchfield Customer Review (What's this?)

    I purchased a Denon AVR-x2000, which is somewhat equivalent in price and level to this 840. I have a simple setup, a top of the line 60" 1080p Panasonic plasma from 2013, and two Ascend Acoustics Sierra 2 speakers. I was underwhelmed by my setup's performance with music, which is the primary purpose of my system. I upgraded my speakers from Sierra 1s to Sierra 2s, but something was still off. My mother needed a receiver, so I decided to give her mine and go with a Yamaha, at the recommendation of a Crutchfield associate. I will never go back. The Yamaha performs tremendously, and I'm hearing the clarity, sharp bass and pronounced mids than I expected to hear when I set up my system. This is also an incredible deal, as long as you don't need HDR capability or Bluetooth. Since I am using a 1080p TV (no 4k HDR) this was perfect for me, and at $550, it's an absolute steal.

    Pros: Excellent sound and clarity with music, WAY outperforms comparable Denon unit.

    Cons: NONE

    Excellent amp!

    jjb from KS on 6/29/2016

    More than satisfied with this amp. Has great power and easy to hook up. Lots of options for hooking up various equipment.

    Excellent receiver, easy to set up, sounds fantastic. Driving Klispsh pair of RP280F towers, RP250c, and a pair of RP 240S speakers. Running my personal desk top into AV port. The picture is beatiful looking in my Samsung plasma TV.

    Pros: Everything, Quality,price, and sound

    Cons: None

    Excellent Receiver

    Alberto Medina from Puerto Rico on 6/12/2016

    Crutchfield Customer Review (What's this?)

    Excellent sound. Great punch and clear definition of sounds. Lots of nice and handy features. Unbeatable price.

    Pros: You can control almost any thing from the remote control. Lots of but-in audio settings. Great punch (bass sound is awesome) and clear definition of sounds.

    Cons: Doesn't have a bottom to physically select which speakers to use when you have to sets of speakers working on a 2 channel mode.

    Yamaha AVENTAGE RX-A840

    Pete from Los Angeles, CA on 5/8/2016

    Crutchfield Customer Review (What's this?)

    I researched high + low before making this purchase. My only gripe about Yamaha is that while they make such great receivers, they don't realize that by making so many models and offering so many choices, they are actually confusing their customers. Who ever imagined anybody could complain about too many choices? It actually made the "educated shopper" part of my purchase much slower. This receiver is so feature-ladden, it seems to have every feature one could imagine + if not used now, then be ready to in the near future. It seems that every electronics company has abandoned graphic EQ's, the one feature I think is so super easy to use, it really allows a user to totally customize their soundless to what a microphone recommends for your room but what your ear likes best. As technology on receivers has changed a lot and they have become wireless network + video devices as much as what was just music players for so many year, this model just feels like it can do it all and really sounds XLNT. It will take me a while to learn all the tricks it can do and use it to it's fullest capabilities, all of which are great problems to have. Many years ago, Yamaha, was the only company to reject generic surround sound field names and give them specific venues, such as the "Roxy Theater". This is another example of innovative design you will not find on a Sony, Denon, or others Impossible to imagine anybody could would regret this purchase, one that will please virtually everybody.

    Pros: Great sounds + every feature under the sun, compatible with all kinds of connectivity.

    Cons: Really none besides having to take a little time to learn how to best set it up + use it to it's maximum design.

    Yamaha Receiver

    Andrea H from Reading, PA on 6/16/2015

    Crutchfield Customer Review (What's this?)

    Just hooked up the Yamaha receiver - had 2 Onkyo's previous to this and they both burned out. So far the clarity and power of the receiver is exactly what we were looking for

    Pros: Claity and Power

    Cons: wish it had Bluetooth capacity

    Replaced my Yamaha RX-V757

    JimF from California on 6/11/2015

    Crutchfield Customer Review (What's this?)

    I bought this as a replacement unit for my Yamaha RX-V757. It was a great unit and I hated to replace it, but its lack of HDMI ports was just making connecting everything way too difficult. The setup of the RX-A840 was relatively quick and easy and all the HDMI ports meant I ended up with significantly less cabling than I had before. The automated setup of the surround speakers was pretty much flawless and with just a couple of minor tweaks I was all done. I added the Bluetooth accessory (Yamaha YBA-11) to complete the input roundup. That too was an easy setup. My iPhone connected right away and I was playing music from my phone (without an annoying cable) right away.

    Pros: Great sound with my Klipsch speakers. Easy setup. iPhone/iPad app works great and will make it easier for my girlfriend to get around the system.

    Cons: None so far. The speaker connections were a bit unclear for my 5.1 system, but I got it figured out.

    10 Days Later (Revised Review)

    Jack from California on 6/11/2015

    Now have unit 11 days and finally have it setup with the help of Crutchfield technical support, the Internet and Many hours of experimentation. Verdict is still out as to whether I'll keep the unit but I do want to correct some things from my first review. FR & FL pre-amp outputs are always functional but at Very low level - inserted graphic equalizer with 12 dB gain and power amp at maximum volume to get level in Living Room equal to Family Room. No longer use party mode as it's too restricted (forces Main room into 7.1 mode :-( I use two modes: 2.1 stereo from CD, FM, Vinyl (digital coaxial), and HTPC (digital optical) and 5.1 surround from Cable, DVD, and HTPC. Classic vocal pop/rock music sometimes sounds pretty good using "Munich Hall" effect. Some music videos downloaded from Internet sound good with Neo 6 Music surround decoder. Never use enhancer or bass boost. Have separate Behringer pre-amp to drive JBL JXR100 as sub-woofer pre-amp output is too low signal level - use it for adjusting sub-woofer level. Installed switchable fan in back of 19" equipment rack for extra cooling. Added Mackie MR8mk3 studio monitor to enhance center channel for movies.

    Pros: - Input trim level controls on each source are helpful. - YPAO is ok as a starting point but needs manual adjustments to better balance speakers - having full manual control is helpful. - Haven't experimented with manual equalizer settings yet - need to get FFT spectral analysis program re-installed on HTPC with large diaphragm condenser microphone.

    Cons: - Doesn't receive Shoutcast or Icecast web streams. I have my own Linux based streaming media (network radio) server. - Must always have TV on to see settings (should be able to do this with web browser on HTPC or Android app). - Always having to push many tiny buttons on remote control to do things, especially to see Input information (is DTS or Dolby 5.1 being recognized and decoded for example - took a long time to get HTPC Kodi (was XBMC) playback software configured properly via HDMI.


    Jack from California on 6/2/2015

    Crutchfield Customer Review (What's this?)

    Unit arrived yesterday, spent all day attempting to get it set-up. Unit is tremendously over complicated even with a masters degree in electrical engineering and computer science and many years of experience with home and professional audio, video and lighting equipment. Now that's it's mostly working, I'm very disappointed and will likely return the unit. Here are some of the reasons: 1. Purchased unit specifically to use pre-amp outputs to mimic main (family) room sound (front speakers) in the living room using external amplifier. Pre-amp outputs don't work if speakers are connected to the front terminals. This is unacceptable! Pre-amp outputs should be just a tap into the signal path to the internal power amp, preferably buffered. 2. WPS did not work to configure wireless Internet, had to do it manually which wouldn't be too bad except unit will NOT display encryption key as you laboriously enter it using tiny buttons on remote control 3. Web browser control via home theater desktop is a joke. Extremely limited in functionality with horrible user interface - totally useless. 4. Android app is better but still lacks much functionality requiring use of remote control. Always pressing button after button on remote control to do anything. 5. Since front pre-amp outputs are broken, used zone 2 outputs for external living room amplifier. Party mode sort of works in that you get same sound source in main and zone 2 but at low level but (see cons for continuation)

    Pros: None worth mentioning compared to my old JVC9010 which worked very well for 13 years before something shorted out (probably a capacitor). Sound is OK, nothing spectacular - so far this unit is a poor value - lots of marginal to useless features while lacking basic audio functionality such as properly designed pre-amp outputs!

    Cons: turning party mode off causes VERY LOUD sound in Zone 2 outputs from say the Tuner or CD player (whichever ANALOG source is selected for Zone 2). With party mode ON, Zone 2 outputs are AFTER volume control. With party mode OFF, Zone 2 outputs are BEFORE volume control - a totally ridiculous design. 6. Can't play music from home theater PC using digital optical connected in Zone 2 except using party mode which forces main room into 7.1 channel stereo instead of 2.1 which is what I want!

    Good system, a couple of drawbacks

    J from Rockport, tx on 4/6/2015

    Crutchfield Customer Review (What's this?)

    Great reciever. Set it up for zone 1 as surround sound on main room tv and zone 2 as outside of house. The iphone app is great to have and setup with Harmony One worked well. Only issue is that you can't AirPlay to just Zone 2 and when air playing to both zones seperate volumes made it a little difficult to get volume correct. I was able to get around the issue a little by air playing to both zones then using the app to switch it only to zone 2 but this took some work. If zone 1 and 2 were truly seperate zones would have given 5 stars. Seems like AirPlay issue is something that could be fixed with a quick programming update. It would be great if AirPlay showed both zones on phone to connect to. Hope they are able to fix this.

    Pros: Easy setup, 2 zones, great sound

    Cons: Not all inputs work on both zones, AirPlay only plays to both zones, AirPlay doesn't support video


    Adam from Littleton Co on 3/20/2015

    Crutchfield Customer Review (What's this?)

    I bought this receiver to replace a older Onkyo that did not have all the functions I needed to make my mismatched speakers sound right. I can no control the tone ( bass/treble ) on each 7 channels . It took a little to to figure out how to do it but now my system is sounding better then ever. All other set up was easy and the on screen display is easy to navigate . No complaints on this unit.

    Pros: Has good system function controls

    Cons: None

    Great Receiver

    Dan from CO on 3/3/2015

    This a great receiver. Very easy to use, the interface is better than any of the other receivers I've used before (Denon/Onkyo/Pioneer most of those are older though).

    Pros: Great sound, significant improvement in Dialogue clarity using same speakers. Adaptvie DRC, Dialogue Level, Dialogue Lift have all been great additions. iPhone iPad app is a nice feature, but could use a few minor improvements. This receiver gives you pre-outs which is the main reason why I got the A840 instead of the A740.

    Cons: Only one crossover point for all speakers (some other models offer an individual setting for each channel, I've read that a single crossover point for the whole system is better to avoid phase alignment issues and that is the reason why Yamaha/Pioneer and few other still only offer a single point. Who knows if that is true or not.

    Great UI

    Austin from Texas on 3/1/2015

    Crutchfield Customer Review (What's this?)

    Replaced my dead after 1 year Onkyo. Overheated, I would assume. Partially my fault, I had a component on top of it that limited air flow. Not doing that to this one.

    Pros: The UI on the Android app is light years ahead of the Onkyo one. Connectivity is excellent.

    Cons: none yet.

    Better than expected, easy set up less than 2hrs ! Replaced older Yamaha.

    Cons: None

    Excellent Receiver

    Bill M from Maryland on 1/23/2015

    Crutchfield Customer Review (What's this?)

    This receiver is built very well, its sound qualities are very clear and precise and its adjustment controls are very straight forward and easy to understand via of its onscreen display using the remote control, but the free Yamaha App is what really simplifies the total operations of this receiver, it gives you total control in each and every sound field and a clearer understanding of the individual adjustments that this receiver has to offer, its an excellent feature. --- I could not be more pleased with purchasing this receiver from Crutchfield, it was at my door the next business day and boxed very securely.

    Pros: Clear and Precise Sound, excellent build quality and its front display has a very attractive uncluttered look to it. The free Yamaha App is incredible, its like sitting behind a soundboard in a production studio.

    Cons: NO Phono Input or dedicated accessory power input for a sub woofer or turntable to turn either on and off when powering the receiver.

    Great Product

    This receiver is excellent and sounds great with my Polk audio speakers. With all of its features I feel I'm covered for a good number of years. I've owned other Yamaha receivers in the past and have loved them all. This one will be no exception.

    Pros: Great for the price

    Cons: None

    Great Receiver

    Mike from Sanford, NC on 10/9/2014

    Crutchfield Customer Review (What's this?)

    After two Onkyos, both with HDMI card problems, I decided to switch. 99% of the reviews I could find on the 'net were good, and they were right. This is a fantastic receiver, with much better sound quality (even my wife remarked on this), and in my opinion much better video quality. I am really enjoying using it. I usually buy all my electronics from Crutchfield, and they are a pleasure to deal with. Standard shipping is fast!

    Pros: Everything.

    Cons: The user manual has to be downloaded or loaded by the CD. Since my desktop is not where I sit to watch TV, I found myself having to walk back and forth to learn the various functions. I finally solved this problem by downloading the manual to my tablet.

    Audio Features

    Aventage Series: The Aventage line of Yamaha AV receivers is based on the audio design concept of providing a massive, full-bodied sound for movie sound effects and the accurate reproduction of music sources. By expertly harmonizing traditional and advanced technologies, every factor that affects sound quality, from materials & parts construction to circuitry layout, vibration damping, and "fine-tuning" the sound, is handled with no other thought than to achieve the best possible audio quality. As a result, every Aventage receiver has the ability to reproduce the most subtle details of high-definition sound, so that listeners can enjoy a truly high-class sound studio experience at home.

    • High Drive Amp Technology: A fully discrete power amplifier helps maximize sound and minimize distortion of the receiver. The Yamaha RX-A840 AV Receiver is equipped with a 7-channel amplifier rated at 100 watts (into 8-ohms, at 20-20kHz, with 0.09% THD, driving 2 channels) which provides high dynamic power with low-impedance drive capability.
    • High Purity Pre-Amplification: The Yamaha RX-A840 uses high quality, audio-grade Burr-Brown 192kHz/24-bit digital-to-analog converters for all channels to maximize sound quality. The AV receiver also utilizes low-jitter PLL circuitry to help optimize sound imaging. The result is a more dynamic sound with greater detail and less distortion.
    • Aluminum Front Panel: The aluminum front panel is used to effectively shield sensitive circuitry from external noise and electronic energy generated by dimmer switches, fluorescent lighting, video monitors and so on. This ensures optimum sonic performance in the widest range of installation environments.
    • A.R.T.: The A.R.T. (Anti-Resonance Technology) Wedge 5th foot is in the center of the unit. It dampens vibrations from the power transformer, power transistors and heat sinks, as well as vibrations that might be caused by the sound from the speakers. A.R.T. Wedge 5th foot helps ensure that vibrations do not affect the sound quality.  The AV receiver also employs anti-vibration heatsinks to suppress vibration from transistors and sound pressure.
    • Independent Power Supplies: Independent power supplies are used for the receiver's analog and digital circuitry to prevent digital noise from affecting analog circuitry. These power supplies are highly efficient and result in less power consumption in standby mode.

    Intelligent Amplifier Assignment: Intelligent Amp Assignment automatically assigns amplifier channels of the Yamaha AV receiver to certain speakers depending on what functions are selected. You can select from a variety of amplifier configurations.

    • Basic: In this configuration, up to nine speakers (Front L/R, Front Presence L/R, Center, Surround L/R, & Surround Back L/R) can be connected to the AV receiver. When Cinema DSP 3D is on, the two Front Presence speakers will be powered and not the two surround back speakers. When Cinema DSP 3D is off, this situation is reversed. Bi-amp and Zone 2 speakers are not available in this mode
    • 5ch Bi-Amp: Up to five speakers (Front L/R, Center, & Surround L/R) can be connected to the AV receiver. The Surround Back amplifier channels of the AV receiver are reassigned to bi-amp the front speakers. A bi-amplification connection uses two amplifiers for one speaker. One amplifier is connected to the woofer section of a loudspeaker while the other is connected to the combined midrange and tweeter section. With this arrangement each amplifier operates over a limited frequency range, making its job easier. Zone 2 and Front Presence speaker are not available in this mode.
    • 7ch + Zone 2: In this configuration, up to nine speakers (Front L/R, Center, Surround L/R, Surround Back L/R, and Zone 2) can be connected to the AV receiver. When Zone 2 is off, all seven channels will be used in the Main Zone. However, when Zone 2 is on, power to the two surround back channels will be directed to the two speakers in Zone 2 and the Main Zone will receive five channels of power. The same or different analog input sources/volume settings can be applied to both zones. Bi-amp and Front Presence speakers are not available in this mode.

    YPAO Automatic System Calibration: The Yamaha Parametric Room Acoustic Optimizer (YPAO) system uses a small microphone and sophisticated equalization to automatically set the best sound for any room, no matter where the speakers are. First, it checks the speaker connections and phase of each speaker. Then it sends out tones which are captured by the microphone to analyze the room acoustics and sets a variety of parameters, such as the speaker size, the distance of the speakers, and even the sound pressure level; until it achieves the best sound conditions for your room.  Up to 8 listening position measurements are taken to optimize the surround effect for a broad area. Additional YPAO technologies include:

    • EQ: You can select between a varietyYPAO EQ result settings to better suit your speaker setup - Natural (adjusts all speaker to a natural sound; useful when the flat setting sounds too bright), Flat (use when all the speakers in the system have similar sound characteristics), Front (EQs the center and rear speakers to sound like the front; useful when your front speakers are better than the others in the system), Through (does not use the YPAO EQ), or Manual (lets you adjust EQ for each channel manually).
    • R.S.C (Reflected Sound Control): The receiver also employs YPAO's Reflected Sound Control (RSC) to correct early reflections for studio-quality sound.
    • DSP Effect Normalization: In addition, YPAO provides DSP Effect Normalization, which varies the CINEMA DSP parameters according to the reflected sounds.
    • YPAO Volume: Human ears have less sensitivity to high and low frequencies, especially at lower volumes. YPAO Volume applies loudness EQ correction to automatically adjust high and low frequency levels as volume changes. Using the YPAO measurement results, EQ correction is optimized to your system settings and listening environment.
    Note: You can also choose to manually adjust the AV receiver's speaker setup settings.

    Multi-Channel Decoding Formats: The Yamaha RX-A840 supports the following multi-channel (Dolby Digital, DTS, Dolby Pro Logic) decoding formats.

    Note: Dolby Digital and DTS listening modes can only be selected if your audio source is connected to the A/V receiver via a digital audio connection (HDMI, optical, or coaxial). To enjoy true 7.1ch Dolby Digital TrueHD and DTS-HD surround sound, the receiver must be connected to your Blu-ray player via HDMI.

    Surround Parameters: The Yamaha AV receiver offers the following Dolby Pro Logic II and DTS NEO:6 audio adjustments.

    • Dolby Pro Logic II Settings: You can adjust the following parameters in Pro Logic II Music modes: Panorama (sends stereo signals to the surround speakers as well as the front speakers for a wraparound effect), Dimension (adjusts the soundfield either towards the front or towards the rear of the room), and Center Width (moves the center channel output completely towards the center speaker or towards the front left and right speakers).
    • Center Image (DTS NEO: 6 Music): This parameter adjusts the front left and right channel output relative to the center channel to make the center channel more or less dominant as necessary.

    Cinema DSP Soundfields: Conventional multichannel audio reproduction systems base their sound on Dolby Digital and DTS decoding, using matrix and steering technologies to create surround sound effects. Yamaha Cinema DSP is much more advanced, actually creating richly realized independent soundfields that envelop you in an unmatched surround sound experience. With dialogue, music and effects ideally located in these separate soundfields, you will hear sound with accurate placement, smooth movement, exceptional clarity and richness, and realistic presence. It will seem as if the walls of your room have disappeared and you are in the middle of your own immense theater. The AV receiver offers 17 Cinema DSP programs for movies, music, and games.

    • Movie Soundfields: Standard, Spectacle, Sci-Fi, Adventure, Drama, Mono Movie, Sports, Action Game, Role Playing Game
    • Music Soundfields: Hall Munich, Hall in Vienna, Chamber, Cellar club, The Roxy Theater, The Bottom Line, Music Video, 5/7ch Stereo
    Note: You can change the receiver's Cinema DSP effect level (level of the soundfield effect to be added); you can adjust the level of the soundfield effect from -6 dB to +3 dB from the receiver or remote control. The AV Controller App for Apple iOS and Android provides even greater adjustment of Cinema DSP soundfields.

    Cinema DSP Modes: The Yamaha RX-A840 AV receiver offers proprietary Yamaha Cinema modes so you can enjoy your movies and music even more in your home; regardless if you are using 5.1 speaker setup, only have a two-channel speaker system, or listening through headphones.

    • Cinema DSP 3D: The actually measured soundfield data in recorded soundtracks contain the information of the height of the sound images. CINEMA DSP 3D mode achieves the reproduction of the accurate height of theses sound images so that it can create the accurate and intensive stereoscopic soundfield in your listening room. The receiver achieves Cinema DSP 3D through its virtual Presence Speaker mode.
    • Virtual Cinema DSP: Virtual Cinema DSP is an algorithm that allows you to enjoy DSP soundfield surround effects while using a minimal two-speaker system. Virtual Cinema DSP lets you enjoy the effects of Cinema DSP surround sound without using surround speakers (handy for use in custom installations where some rooms don't have surround speakers). It can be used with the front/center speakers or even with just the two front left and right speakers. This unit will switch to virtual Cinema DSP mode automatically when surround speakers are unavailable.
    • Virtual Cinema Front: With Virtual Cinema Front, you will enjoy virtual 5-channel surround sound with higher quality and resolution by installing surround speakers at the front. You get more flexibility to arrange your speakers inside the room, along with easy enjoyment of high quality surround sound.
    • Silent Cinema: Silent Cinema makes it possible to hear large-scale surround sound through ordinary headphones. This is a variation of Cinema DSP technology that Yamaha developed to let you listen in private to movies and other multi-channel sources for hours without listening fatigue.

    CINEMA DSP Parameters: You can adjust the following parameters of the Cinema DSP modes.

    • DSP Level: You can change the receiver's CINEMA DSP effect level (level of the soundfield effect to be added). You can adjust the level of the soundfield effect from -6 dB to +3 dB.
    • Delay: Adjusts the delay between the direct sound and the presence soundfield (1-99ms), surround soundfield (1-49ms), and surround back soundfield (1-49ms).
    • Room Size: Adjusts the broadening effect (0.1-2.0) of the presence soundfield, surround soundfield, and the surround back sound field.
    • Liveness: Adjusts the loss (0-10) of the presence soundfield, surround back soundfield, and surround back soundfield.
    • Reverb: Adjusts the delay time of the rear reverberant sound (1.0-5.0s), the delay between the direct sound and rear reverberant sound (0-250ms), and the volume of the reverberant sound (0-100%).

    HiFi Sound Modes: The Yamaha RX-A840 offers two HiFi audio modes which bypass the receiver's tone & DSP processing for higher sound quality performance. These HiFi sound modes lets you play back input sources without any soundfield effect processing. When either of theses modes are enabled, each speaker produces its own channel audio signal (without soundfield processing). When playing back 2-channle sources, such as a CD player, stereo sound is heard from the front speakers. When playing back multichannel sources, the receiver produces unprocessed multichannel surround sound.

    • Straight: 2-channel stereo sources are output from only the front left and right speakers, while multi-channel sources are decoded straight into the appropriate channels without any additional tone or DSP processing.
    • Pure Direct: Turns off the surround and tone circuitry, and dims the front-panel display, allowing sources to bypass the decoders and DSP processors of this unit so you can enjoy pure hi-fi sound from 2-channel or multi-channel sources. During Pure Direct playback no sound is output from the subwoofer.

    Compressed Music Enhancer: Yamaha employs sophisticated digital signal processing with exclusive algorithms to enable playback that improves the performance of compressed music formats, including MP3, WMA, and AAC. With the Compressed Music Enhancer, highs and especially lows are richer and smoother, bringing music back to life to be as close to the original as possible.

    Dialogue Lift & Level Adjustment: Dialogue Lift raises the sound of dialogue from the center speaker to a position in the center of the screen. Newly developed virtual dialogue lift achieves dialogue lift function even without the need for presence speakers. Dialogue Level Adjustment lets you control the volume of the vocal sound, so you hear movie dialogue and music vocals at the ideal level for clear, comfortable listening.

    Dynamic Range Control: The Yamaha RX-A840 employs two Dynamic Range Control functions.

    • Adaptive DRC: Adaptive DRC automatically adjusts the dynamic range of the sound according to the volume level. This ensures that you hear clear dialog, vocals, and all sound effects at comfortable levels. There is no need to adjust the volume level as you listen; everything from whispers to big explosions will be heard clearly and comfortably at the same volume setting. It also tones down loud TV commercials and is ideal for low-volume, late-night listening when you do not want to disturb others.
    • Dynamic Range: The amount of dynamic range compression applied to bitstream signals is adjustable; Min/Auto is suitable for low volume listening, Standard is typical for home use, and Max doesn't compress the dynamic range at all.

    Bass Management: The Yamaha RX-A840 AV receiver provides the following Bass Management settings.

    • Bass & Treble: You can adjust the balance of the high-frequency range (Treble) and low-frequency range (Bass) of sounds output from the receiver' front left and right speakers to obtain a desired tone. You can independently adjust the bass (50Hz) and treble (20kHz) from -6dB to +6dB in 0.5 dB increments. The tone control of the speakers or headphones can be set separately.
    • Extra Bass: You can select whether to play front channel low-frequencies through either of the front speaker or the subwoofer, or through both the subwoofer and front speakers.
    • Subwoofer Trim: The Subwoofer Trim control enhances the low frequencies by avoiding overlap with the front speaker output. This will result in a cleaner, more focused sound stage while providing a seamless frequency response. When subwoofer frequency overlap occurs in conventional systems, the overall sound is "pushed" toward the subwoofer. Subwoofer Trim takes care of this by separating the low subwoofer frequencies cleanly, thus stabilizing the front stage while providing a well-balanced enhanced bass sound.

    Volume Setup: The Yamaha RX-A840 allows you to customize the receiver's volume levels.

    • Max Volume Adjustment: Use this feature to set the receiver's maximum volume level. This feature is useful to avoid turning the volume too loud by mistake. You can set the Max Volume from -30 dB to +15 dB in 5 dB steps, or to +16.5 dB (full volume range is -80 dB to +16.5 dB).
    • Initial Volume Setting: Use this feature to set the volume level when the power is turned on. You can choose between Off (same as the volume when the unit was turned off), Mute, and -80 dB to + 16.5 dB in increments of 0.5 dB.
    • Volume Trim: Use this feature to adjust the volume level of each input. This is useful to balance the level of each input to avoid sudden changes in volume when switching between input sources. The range is from -6dB to +6dB in 0.5dB increments.
    Note: You can choose to display the "Relative" volume scale (-80 to +16dB) or an "Absolute" volume scale (0 to 97).

    Audio Inputs/Outputs: The Yamaha RX-A840 offers a variety of analog and digital audio inputs/outputs.

    • Digital Inputs: The Yamaha AV receiver is equipped with two optical (toslink) digital inputs and two coaxial (RCA) digital inputs capable of handling 2.0-5.1ch/32-96kHz audio.
    • Stereo RCA Jacks: The receiver is also equipped with five stereo RCA analog audio inputs (4 rear/1 front), stereo RCA analog audio record output, and stereo RCA Zone 2 output.
    • Speaker Terminals: The receiver has binding post terminals for the Front, Center, Surround, and Surround Back/Bi-Amp speaker terminals. The Zone 2/Presence speakers terminals are spring-clip. The binding posts can accept bare wire, pin connectors, and single banana plugs. These terminals are spaced too far apart for dual banana plugs and a collar surrounding them prevents the use of spade connectors. The spring-clip terminals only accept bare wire or pin-connector. You can select 8 ohms or 6 ohms in the menu depending on your speaker application. The amplifier supports 4- to 8-ohm Front speakers, and 6- to 8-ohm Center and Surround speakers.
    • 7.2ch Preamp Outputs: The A/V receiver features 7.2-channel pre-amp outputs (Front L/R, Center, Surround L/R, Surround Back L/R, and Dual Subs) for connection to external power amplifiers. The dual sub outputs are not discrete.
    • Headphone Jack: The Yamaha RX-A840 is equipped with a front-panel 1/4" headphone jack for connecting a set of headphone, so you can listen to your music privately. Connecting a set of headphones automatically mutes the receiver's speaker outputs. Sound effects applied during playback can also be heard through the headphones.

    USB/iPod Integration

    USB Port: This AV receiver is equipped with a front-panel USB (type-A) port that allows you to enjoy a variety of music files stored on a USB mass storage class memory device; such as select Android smartphones (Froyo/Gingerbread OS only), portable MP3 players, or USB thumbdrives (not compatible with USB HDDs). Your USB mass storage class device must be formatted in FAT 16 or FAT32 .You can use the receiver's on-screen menu (via HDMI) and remote control to navigate your stored music files on your connected USB memory device. USB portable audio players that can be charged via USB will be charged when plugged into the AV receiver's USB port (5V/2.1A); even in standby mode. Compatible music files include:

    • MP3 (up to 48 kHz)
    • WMA (up to 48 kHz)
    • AAC (up to 48 kHz)
    • ALAC (up to 96 kHz)
    • WAV (up to 192 kHz)
    • FLAC (up to 192 kHz)
    Note: While listening to a song from a USB device, you can view a favorite video or photo from the receiver's monitor output.

    iPod/iPhone Connectivity: The Yamaha RX-A840 offers wired (via USB) and wireless (via AirPlay) connectivity for your Apple iPod, iPhone, or iPad. You can even watch video from your Apple device via the receiver's front-panel HDMI input.

    • AirPlay: AirPlay lets you stream your favorite songs directly from your Apple iOS (4.3.3+) device or from your iTunes (10.2.2+) library on your Windows PC or Mac computer to the AV receiver, over your home's wireless network connection. From your Apple iOS device you are able to stream stored music on your device, downloaded music apps, and music on your iCloud to the AV receiver. From your Windows or Mac you can stream your stored iTunes music library on your computer to the AV receiver; you can even download Apple's free Remote App onto your compatible iOS device to browse and control playback functions of the the music stored in your iTunes music library on your computer that is being streamed to the AV receiver.

    • USB Direct: The USB (type-A) port on the front-panel provides convenient connection for your iPod/iPhone so you can listen to your stored music and music apps through the Yamaha AV receiver. The iPod/iPhone USB digital connection means that the digital audio signal from your iPod/iPhone is transmitted directly to the system, minimizing noise interference and allowing use of the receiver's DAC, not the DAC in your iPod/iPhone. This results in more precise sound reproduction. You can navigate your iPod/iPhone's music via the receiver's on-screen menu (via HDMI) and remote control, or continue to use your iPod/iPhone's clickwheel or touchscreen. You can browse your iPod/iPhone's stored music content via Playlist, Artist, Album, Song, Genre, or Composer. You can also control Repeat & Shuffle functions.

    Convenience Features

    Advanced On-Screen Menu: The RX-A840 offers an on-screen (GUI) menu system through its HDMI output. The simple on-screen display combines text and graphics that make setup and other operations extremely easy. If your TV is connected to the composite video or component video monitor output, you will need to use the AV receiver's front-panel display when changing settings. You can set the receiver's on-screen menu language to English, French, Spanish, German, Russian, or Chinese.

    Scene (for One-Touch Start): The RX-A840 features four Scene buttons on the front-panel and remote to make operating the receiver easier. Pressing a Scene button will automatically launch a number of operations that initiate play of the source controlled by that button; such as powering on the receiver, switching to the appropriate source input, and recalling the selected DSP surround mode.

    Multi-Zone: The Yamaha RX-A840 offers Zone 2, Party Mode, and HDMI Zone B functionality for playback of audio (HDMI Zone B also supports video) in two separate rooms of your home.

    • Zone 2: The Zone 2 feature allows you to set this receiver to reproduce separate input sources in the main zone and the second zone (Zone 2). The receiver has dedicated stereo RCA outputs for Zone 2, or the built-in amplifier can be configured to power speakers in the second zone connected to the Extra Speaker terminals. By using the RCA outputs on the AV receiver you can connect an external receiver or integrated amplifier in a second room, allowing you to listen to 7.1ch surround in the main room and play a different stereo audio source in another room of your home. The volume of Zone 2 is controlled by your optional integrated amp. By using the speaker-level outputs on the AV receiver you can directly connect a secondary pair of speakers in another room of your home, allowing you to listen to 5.1 surround sound in your main room and play a different stereo audio source in the other room. When the receiver is powering speakers in Zone 2, the surround back speakers in the main room are turned off (limiting you to 5.1ch in the main room). The volume of Zone 2 is controlled by the AV receiver
      • Compatible Zone Sources: You can select the following input sources for Zone 2.
        • Analog Audio Inputs
        • AM/FM Tuner (you cannot select different AM/FM radio stations for each zone)
        • USB (including iPod/iPhone) & AirPlay
        • Internet Radio (different network sources cannot be played back in multiple zones at the same time)
        • DLNA/Media Player contents
      • Incompatible Zone Sources: Optical/coaxial digital and HDMI audio sources are not output to Zone 2. You cannot output any video signal to Zone 2. Unfortunately, you cannot select USB and Network source exclusively for each Zone. For example, if you select "Network Server" for Zone 2 when "USB" is selected for the Main Zone, the input source in the Main Zone also switches to "Network Server".
    • Party Mode: The Party Mode allows you to enjoy the AV receiver's Main Zone audio source in Zone 2, simultaneously (regardless of input audio signal types - analog or digital). During the party mode, stereo playback is automatically selected for all zones. The Main Zone & Zone 2's volume can be adjusted independently. Utilize this function when you want to play back an audio source as background music in two rooms of your home.
    • HDMI Zone B: The receiver's second HDMI monitor output lets you send the same HDMI audio/video input signal that is being played in the main zone to a second zone (video is output at the resolution supported by both TVs).

    Gapless Playback: Many live and classical albums have no gaps in the music. Gapless playback ensures that there are no pauses between audio files. This provides playback with no interruptions, the way it was meant to be heard. Compatible with WAV, FLAC, and ALAC music files via USB or DLNA.

    Input Rename: You can rename each input so the display reflects the actual source; choose from 15 templates or create an original name, up to nine characters.

    Display Dimmer: You can set the brightness of the front-panel display from -4 to 0.

    ECO Mode: When the ECO Mode is enabled, you can reduce the receiver' power consumption by keeping the maximum volume, maximum output power, and front display's brightness low. ECO mode reduces power consumption by approximately 20%.

    Timers: The receiver offers a programmable Sleep Timer and Auto Power Down function.

    • Sleep Timer: The receiver's Sleep Timer function can be set turn the unit automatically off after 30, 60, 90, or 120 minutes.
    • Auto Power Down: If you don't operate the receiver or use the remote for an extended period of time, the unit will automatically go into standby mode (Auto Power Down function). The Auto Power Down feature is selectable from 2, 4, 8 or 12 hours.

    Memory Guard: This feature is used to prevent accidental changes to the DSP program parameter values and other system settings.

    Remote + Bluetooth Control

    IR Remote w/ HDMI-CEC: The receiver comes with an IR remote control for wireless operation of this receiver and other HDMI-connected sources (via HDMI-CEC). HDMI-CEC (Consumer Electronics Control) synchronizes the operation of this unit with other HDMI-CEC devices when connected via HDMI. When the AV receiver is connected to a HDMI-CEC compatible TV, they will turn ON/OFF together and you can use the TV remote to control the volume of the receiver. HDMI-CEC also provides playback functionality with other components, such as your Blu-ray player. For example, you can use the receiver's remote control to operate player functions like Play/Pause, Fast Forward/Rewind, Previous/Next Track, or Stop.

    Note: Not all HDMI-CEC compatible components and functions are guaranteed to work.

    AV Controller App: Download Yamaha's free AV Controller App (from Apple's App Store or GooglePlay) onto your Apple iOS (5.0+) or Android (2.1+) device and turn your mobile device into a Wi-Fi enabled remote control for the Yamaha AV receiver.

    • Internal Content Browsing: Using this app on your Apple iOS or Android device, you can browse and listen to content from all internally available sources; such as Internet Radio, Pandora, Spotify, USB devices, and the AM/FM tuner.
    • Wireless Music Streaming: From the app, you can browse music stored on your Apple iOS or Android device and wirelessly transfer the content to the Yamaha A/V receiver for playback.
    • Zone Control: You can control power on/off, source selection, volume and other functions of Zone 2. Customization such as changing zone icon and renaming zone is also supported.
    • Blu-Ray Player: This App not only controls the Yamaha AV receiver, it also controls Yamaha Blu-ray Disc Players, supporting various functions including Play/Pause, Stop, Fast Forward/Rewind, and Previous/Next Track.

    AV Setup Guide App: Download Yamaha's AV Setup Guide App (from Apple's App Store or GooglePlay) onto your Apple iPad (iOS 6.0+) or Android tablet (OS 4.0+) for assistance with connecting cables between the Yamaha AV receiver and your source devices as well as AV receiver setup. This app guides you through various settings including speaker connections, TV and source device connections, plus assigning the power amplifier. Once you have completed the setup guide, settings from this app will automatically be copied to your network-connected AV receiver for quick and easy setup.

    Remote Connections: The RX-A840 offers a variety of remote connections.

    • 12V Trigger Output: The RX-A840 has a programmable minijack output to send a 12-Volt DC turn-on signal to another component that accepts a 12V trigger, such as a power amplifier or motorized projection screen. The trigger is programmed either to work with a specific zone (main room or Zone2) or a specific source.
    • Remote Jacks: The receiver has remote input and remote output minijack terminals for use with external IR receivers and compatible Yamaha components.
    • RS-232C Port: The AV receiver's RS-232C port provides seamless integration with a wide range of third-party home automation control systems.

    Add-on Bluetooth Audio Receiver: The Yamaha YBA-11 Bluetooth Audio Receiver (022YBA11, sold separately) can be used to wirelessly connect your Bluetooth-enabled mobile devices to the Yamaha AV receiver. The YBA-11 connects to the digital coaxial audio input on the back of the Yamaha AV receiver and is powered by the rear-panel DC Out/USB type-A port (5V/0.5A) of the receiver.

    Thanks for your question. Yes you are correct, an adapter would be needed. On the product page under the "Accessories" tab, choose "Wireless Adapters" on the left and it will show you several adapters that are compatible. Prices range from 49.99 to 199.99. Hope that helps. [ Kenny  May 04, 2016 ]  Staff
    Sorry I don't use zone 2 at this time, not sure the answer.. but I'm sure the specialist at Crutchfield can answer this... [ HOG2K  Aug 12, 2015 ]
    The unit I bought from Crutchfield does NOT have a voltage switch, however according to the user manual I downloaded, some do have the switch. I guess it depends on where you purchase it. [ MICHAEL  Jun 08, 2015 ]
    There's no voltage switch that i'm aware of. Just checked back of unit and don't see anything. [ Michael  Jun 07, 2015 ]
    Good question ED, sorry I just don't know the answer to that one.. best bet is to always ask Crutchfield people... these guys have helped me every time I needed help. [ HOG2K  Feb 27, 2015 ]
    I sent it back and realy don't remember.I was using everything in HDMI.i'm not sure but I think there was a way to adjust the trim on each input. But don't quote me on that. [ JOE  Feb 26, 2015 ]
    What do you mean by that? I use this for my surround sound for TV and movies only. I use the "Main speaker" pre-amp out into my Musical Fidelity amp and, in this case, the Yamaha controls the volume of the Musical Fidelity amp. When I just want to listen to music - I have the inputs for my music plugged directly into my Musical Fidelity: CD player; DAC etc. etc. And the musical Fidelity controls the volume. The only thing going into my Yamaha is my cable box and Blu-ray. I didn't need a higher end surround unit. This Yamaha is sufficient for what I watch. But for music, no surround is good enough. I always use the pre-out from the surround into the input of a "Good" Integrated amp or pre-amp. [ JOHN D  Feb 26, 2015 ]
    I'm sorry I cannot help you with this. I can't find "video background" in the user manual, and I've never wanted to watch two videos at once, so I have not attempted this. [ MICHAEL  Dec 02, 2014 ]
    I have not tried to do either so I do not know [ ALAN  Dec 02, 2014 ]
