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.
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.
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.
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.
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.
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.
Your receiver powers your speakers and lets you connect and select your entertainment sources. But a great receiver does a lot more it ignites your emotions. From the passion of a favorite musical artist, to the crossfire of a super-charged movie soundtrack, to the intensity and immersion of a fast-paced video game, your receiver is the key to experiencing and enjoying it in full.
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
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.
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.
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!
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
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
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.
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.
Pros: This replaced older Yamaha it was plug n play to re-rack the new rig better than expected great sound sound, heavy options for fair price!
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.
Plug and Play, It's almost that simple. Easy set Up, Great sound and Good looking unit.
Pros: Easy Set Up, Great Dynamic sound.
Cons: None that I can think of.
Excellent reciever. Amazing sound and does everything I wanted with ease. A nice upgrade from my 6 year old Onkyo.
Pros: Clean Looks, Great powerful sound, Easy to use.
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
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!
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.
Replaced my Onkyo receiver with RX-A840. Unit was very easy to set up the speaker set up was outstanding, Great features, sound was excellent, inputs and outputs are very easy to assign and control control.
Pros: Set up functions are very simple to follow, Sound results are great. This was my first time working with Crutchfield and the experience was excellent, They were very helpful and the service was excellent including the prompt delivery after I purchase the unit
Easy to order with next day shipping. I installed it myself, following the directions provided and have a great surround sound in my family room, and a second zone in my living room. I can play my entire iTunes library from my computer, phone or IPad. Best of all, with the downloaded Yamaha app I can control the AV receiver from either room on either floor. Just what I wanted.
Pros: Easy to install.
Cons: Don't know yet. None so far.

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.
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.
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:
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.
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.
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 Parameters: You can adjust the following parameters of the Cinema DSP modes.
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.
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.
Bass Management: The Yamaha RX-A840 AV receiver provides the following Bass Management settings.
Volume Setup: The Yamaha RX-A840 allows you to customize the receiver's volume levels.
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.
HDMI 2.0: The Yamaha RX-A840 AV receiver is fitted with eight HDMI 2.0 (7 rear/1 front) inputs and two HDMI 2.0 outputs to deliver crystal-clear, all-digital audio and video signals. The two HDMI outputs are parallel, so the same audio/video signal is output through both and can be used simultaneously. The HDMI 2.0 jacks support 4K/60Hz and 1080p video signals; as well as 3D video and ARC functionality. Deep Color (30/36 bit), x.v.Color, and auto Lip-Sync compensation is also supported via HDMI. The AV receiver's HDMI jacks support 2-channel and multi-channel linear PCM (up to 8-channel) and Bitstream (Dolby Digital, DTS, etc) digital audio formats.
Note: The AV receiver's HDMI 2.0 jacks do not support the latest HDCP 2.2 copyright protection for 4K ultra-HD content, so it will not support 4K content from satellite/cable providers, online video services, and Blu-ray disc which are copyright protected with HDCP 2.2.
4K Video Upscaling: The Yamaha RX-A840 is capable of outstanding upscaling and i/p conversion quality. This AV Receiver will upscale video signals from analog (480i only)-to-HDMI and HDMI-to-HDMI, up to 4K. This means a much better picture with HDTVs capable of 720p, 1080i, 1080p, or 4K resolution.
Front-Panel HDMI/MHL Port: One of the receiver's six HDMI inputs is on the front-panel and MHL compatible. This MHL compatible HDMI port provides easy, direct connection of MHL compatible smartphones, like Android. Playback of up to 1080p video and multi-channel audio from the phone is supported. The receiver will also charge (5V/1A) your connected phone. Play, Stop, and other basic operations can be controlled from the AV receiver's remote control.
HDMI Standby Through Mode: When the RX-A840 is in standby mode (power off), the Standby Through feature allows HDMI source signals to pass through the receiver to the TV. The HDMI input can be changed using the remote control. So, there's not need to turn on the A/V receiver in order to switch HDMI sources.
Analog Video: The RX-A840 AV receiver offers both composite and component analog video jacks.
Background Video: The Background Video feature allows you to watch a video source while listening to a different audio source. With the RX-A840, you can select any video input, and listen to AM/FM radio or select songs from a USB device or Network source at the same time.

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... [ MIKE 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. [ MIKE 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 ]
