Our take on the Yamaha AVENTAGE RX-A870 by Crutchfield's Deia Z.
Lose yourself in movies and music
Looking to take your home theater to the next level? Match Yamaha's AVENTAGE RX-A870 to a 4K Blu-ray player and you can enjoy the same video content in crystal-clear Ultra HD on up to two compatible displays — perfect if you have both a TV and a video projector. Dolby Atmos and DTS:X bring movie soundtracks to life with incredible realism.
Music lovers will appreciate this receiver's ability to play different high-resolution audio formats through the front-panel USB port or from a networked computer. And if you're into vinyl, a phono input provides an easy connection for your turntable.
The AVENTAGE difference
For their AVENTAGE-series receivers, Yamaha uses custom-designed parts with anti-resonance technology to reduce distortion caused by vibration. A rigid H-shaped frame adds stability to cut out chassis vibration almost completely. A specially designed fifth foot at the center of the receiver's base dampens internal and external vibrations, and an aluminum front panel further reduces resonance to maximize sound quality.
The RX-A870's meticulous construction, symmetrical amplifier layout, and low-jitter digital circuitry all work together to give you accurate sound with precise stereo imaging and a wide, natural soundstage.
Loads of wireless listening options
Built-in support for streaming services like Spotify®, TIDAL, and Pandora® lets you play and control your favorite music directly through the receiver. Apple® AirPlay® lets you stream from a compatible iOS® device, and Bluetooth adds even more streaming flexibility. You can even stream audio from the receiver to a set of Bluetooth headphones — great for late-night listening.
MusicCast lets you choose how to listen
Setting up a whole home wireless music system has never been easier. This receiver's built-in MusicCast technology lets you add audio playback in up to nine additional rooms with compatible Yamaha wireless speakers and sound bars.
MusicCast lets you stream music from your personal collection, internet radio, and streaming services. You can also play Bluetooth sources, sound from your TV, and even CDs and vinyl. The free MusicCast Controller app makes it easy to access your music and control what you have playing in different rooms.
Flexible speaker connections for a custom sound system
The RX-A870 has outputs for nine speakers, giving you a few different configuration options. You can set up a standard 7.2-channel surround sound system or a 5.1.2 Dolby Atmos system, and use the extra two speaker outputs to power a pair of speakers in a second room. That way, you can enjoy stereo music in Zone 2 while others watch TV in the main room.
When Zone 2 is powered on, Yamaha's Intelligent Amp Assign feature automatically redirects the power for the two surround back channels — or the front height channels, depending on your configuration — to your stereo setup in Zone 2, giving you five-channel surround sound in the living room.
If you're happy with a simple 5.2-channel surround sound system, you can also use one of the extra sets of speaker outputs to bi-amp your front speakers for more powerful sound.

Thanks for submitting your review
Features and Specs
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-A870 AV Receiver is equipped with a 7-channel amplifier rated at 100 watts (into 8-ohms, at 20-20kHz, with 0.06% THD, driving 2 channels) which provides high dynamic power with low-impedance drive capability.
- High Purity Pre-Amplification: The Yamaha RX-A870 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.
- 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.
- 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.
- Anti-Resonance Technology: The Anti-Resonance Technology (A.R.T) Wedge is a fifth foot 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.
- Advanced Design Feet: The feet of the receiver feature a newly designed, high-density structure which utilizes two different kinds of interior ribs (straight and curved) to enhance strength and damping performance. Installation stability is improved and chassis resonance is dispersed, effectively eliminating external vibration. The low-range response is enhanced, while resonance peaks in the mid- and high-range are reduced, providing dynamic sound and accurate reproduction.
Intelligent Amplifier Assignment: Intelligent Amp Assignment automatically assigns amplifier channels of the Yamaha AV receiver to certain speakers depending on what speaker layout has been selected and what content is being played back. You can connect up to nine speakers to the AV receiver and it will determine which seven speakers need amplification. You can choose from a variety of amplifier speaker layout configurations.
- 7.1/5.1.2 Surround: 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 HD3 is on or a Dolby Atmos soundtrack is being played, the two Front Presence or Dolby Atmos speakers will be powered and not the two Surround Back speakers. When Cinema DSP HD3 is off or Dolby Atmos is not playing, this situation is reversed and the Front Presence or Dolby Atmos speakers turn off while the Surround Back speakers are powered. Bi-amp and Zone 2 speakers are not available in this mode.
- Dolby Atmos + Zone 2: In this setup, you can hook up a 5.1.2ch Dolby Atmos speaker system in the main room and a pair of speakers in Zone 2 to the receiver. When Zone 2 is off, all seven channels of your Dolby Atmos speaker system will be powered. However, when Zone 2 is turned on, power to the Front Height, Overhead, or Dolby Atmos speakers will be cut off and directed to the pair of speakers in Zone; limiting you to only 5.1ch surround in the main room. Bi-amp & Surround Back speakers are not available in this setup.
- 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, Front Presence, & Dolby Atmos 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, Front Presence, & Dolby Atmos speakers are not available in this mode.
YPAO Sound Optimization: This unit employs the YPAO (Yamaha Parametric Acoustic Optimizer), which automatically adjusts the output of the speakers based on placement, performance, and the room's acoustic characteristics. Yamaha's 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 volume level; until it achieves the best sound conditions for your room.
- R.S.C. (Reflected Sound Control) Multipoint: The receiver employs R.S.C. (Reflected Sound Control) to correct early reflections for studio-quality surround sound. Up to 8 listening position measurements are taken to optimize the surround effect for a broad area (you can store up to two speaker patterns).
- EQ: 6Choose between 3 YPAO EQ modes - Natural (adjusts all speakers 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), or 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)
- DSP Effect Normalization: In addition, the receiver's YPAO Sound Optimization provides DSP Effect Normalization, which varies the Cinema DSP parameters according to the reflected sounds in the room.
- 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, crossover, & EQ settings.

Immersive Surround Sound: The Yamaha RX-A870 AV receiver goes beyond regular surround with the latest immersive surround sound formats, including Dolby Atmos & DTS:X.
- Dolby Atmos: The Yamaha AV receiver will enhance properly designed systems with Dolby Atmos where sound comes alive from all directions, including overhead, to fill the home theater with astonishing clarity, power, detail and depth. The RX-A870 has the processing power to run a more enveloping 5.1.2ch Dolby Atmos layout utilizing front-height, ceiling mounted, or Dolby Atmos-enabled speakers (sold separately). A 5.1.2 speaker configuration is based upon a traditional 5.1 speaker layout complemented by two Front Height, Overhead, or Dolby Atmos-enabled speakers.
- DTS:X: DTS:X is the next generation object-based, multi-dimensional audio technology from DTS. Unbound from channels, DTS:X conveys the fluid movement of sound to create an incredibly rich, realistic and immersive soundscape - in front of, behind, beside and above the audience - more accurately than ever before. DTS:X offers the ability to automatically adapt the audio to the speaker layout that best fits your space.
Post Decoding Formats: The Yamaha AV receiver supports Dolby Surround, Neural:X, and DTS Neo:6 (Music/Cinema) to enhance 2-channel and multichannel decoding formats.
- Dolby Surround: Dolby Surround offers an enhanced cinema experience to your 2ch and multichannel movie soundtracks using your existing 5.1ch, 7.1ch or Dolby Atmos speaker setup. Dolby Surround enhances audio definition by improving the spatial dimension and overall audio definition of movie soundtracks. It does this by using four distinct surround zones that provide greater control over the exact placement of each detail in a movie sound track, so audio can be matched more accurately to the video on screen; this means more depth and greater realism for your movies. As a result, individual sounds are clearer and more distinct. It also improves the surround sound experience across the entire theater by widening the listening "sweet spot".
- Neural:X: DTS:X incorporates Neural:X, the latest spatial remapping technology from DTS, which provides a fully immersive output for all types of source content; this includes DTS bitstreams and non-encoded (PCM) data. Neural:X delivers a thrilling sense of immersive sound to your speaker layout regardless of the original source format.
- DTS Neo:6: DTS Neo:6 is an advanced matrix decoder that takes any two-channel source (including television broadcasts, CDs and DVDs) and expands it into five or six channels. It also provides separate, optimized modes for stereo music materials and matrix surround motion picture soundtracks. DTS Neo:6 brings you a more revealing sound from ordinary stereo and a more expansive home cinema experience.
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 these sound images so that it can create the accurate and intensive stereoscopic soundfield in your listening room. Yamaha Cinema DSP 3D lets you 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.
- Virtual Presence Speaker (VPS): With the power of Cinema DSP 3D technology and the Virtual Presence Speaker (VPS) mode, the receiver virtually reproduces the height of the 3D soundfield without actually having front presence speakers. The Virtual Presence Speaker function makes full use of center and surround speakers to create audible information from where presence (height) speakers are normally installed.
- Virtual Surround Back Speaker (VSBS): This receiver also features a Virtual Surround Back Speaker function. Even without using surround back speakers, you can experience more natural, lifelike sound from behind you without physical speakers being installed in the surround back area of the listening environment.
- 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 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 dialog, 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, 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.
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-A870 offers two HiFi audio modes which bypass the receiver's tone & DSP processing for higher sound quality performance. These HiFi sound modes let you play back input sources without any soundfield effect processing. When either of these modes are enabled, each speaker produces its own channel audio signal (without soundfield processing). When playing back 2-channel 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, AAC, & Bluetooth (SBC/AAC). The Yamaha receiver's Compressed Music Enhancer feature is even optimized for Bluetooth wireless audio streaming. 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 Level & Lift: Dialogue Level Adjustment lets you control the volume of the vocal sound, so you hear movie dialog and music vocals at the ideal level for clear, comfortable listening. Dialogue Lift adjust the perceived height of dialogue sounds. If the dialogue sounds as if it in coming from below the TV screen, you can raise its perceived height by increasing this setting.
Dynamic Range Control: The Yamaha RX-A870 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-A870 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 the front speaker or the subwoofer, or through both the subwoofer and front speakers. Use the Extra Bass feature to amplify bass tones, not just in your main room but also on systems in Zone 2. Even with compact or in-wall speakers which typically lack bass, you'll hear all your sources with powerful bass sound.
- 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.
- Zone 2 Volume Equalizer: Automatically adjusts bass and treble balance to match the volume on systems in Zone 2. Enjoy movies and music with a natural sound quality balance even at low volumes.
Volume Setup: The Yamaha RX-A870 allows you to customize the receiver's volume levels.
- Volume Scale: You can choose to display the "Relative" volume scale (-80 to +16dB) or an "Absolute" volume scale (0 to 97).
- 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 -30dB to +15dB in 5dB steps, or to +16.5dB (full volume range is -80dB 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 -80dB to + 16.5dB in increments of 0.5dB.
- Input 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.
Audio Outputs: The Yamaha RX-A870 AV receiver is fitted with binding-post speaker terminals and 7.2ch RCA pre-outs, along with a front-panel headphone jack.
- Speaker Terminals: The receiver has binding post terminals for all speaker outputs. 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. 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 Pre-Out: The AV receiver features 7.2-channel pre-outs (Front L/R, Center, Surround L/R, Surround Back L/R, and Dual Subs) for connection to external power amplifiers. The pre-outs are variable. The dual sub outputs are wired in parallel and output the same signal (they are not discrete).
- Headphone Jack: The Yamaha RX-A870 is equipped with a front-panel 1/4" headphone jack for connecting a set of headphones, 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.
Phono Input: The Yamaha RX-A870 AV receiver features a dedicated Phono (MM) input for connecting your turntable and listening to your vinyl records.
Front-Panel Aux Input: The RX-A870 features a front-panel Aux input (3.5mm) for connecting your portable audio player with a headphone output.
HDMI 2.0a: The Yamaha RX-A870 AV receiver is fitted with eight HDMI 2.0a inputs (7 rear/1 front) and two HDMI 2.0a outputs that support the latest HDMI standards; such as 4K/60Hz, 4:4:4 color subsampling, HDR (High Dynamic Range), & Wide Color Gamut (BT.2020). The receiver's HDMI 1-3 inputs and both HDMI outputs also support HDCP 2.2 for full support of today's 4K content from Ultra HD Blu-ray, online video services (like Amazon & Netflix), and future TV broadcast services.
- 4K/60Hz: The RX-A870 supports up to 4K (3840x2160 pixels) video @ 60 frames per second on all of its HDMI inputs and output. It also supports a 480i, 480p, 720p, 1080i, or 1080p video signal.
- HDCP 2.2: Only the receiver's HDMI 1-3 inputs and both HDMI outputs support HDCP 2.2, which fully complies with the latest copyright protection standard for 4K video transmission.
- 4:4:4 Color Subsampling: The receiver also supports RGB, YCbCr 4:4:4, YCbCr 4:2:2, and YCbCr 4:2:0 color subsampling (@ 60Hz or 50Hz). With 4:4:4 color subsampling, luminance (brightness) and chroma (color) are sampled at the same rate; resulting in an RGB color palette as big as the video sampling rate for a video image with more colors, plus greater color accuracy and detail.
- Wide Color Gamut (BT.2020): The BT.2020 color standard delivers a much wider color gamut and represents about 75% of the total visual color spectrum, while the current Rec. 709 color standard selected as the color space for HDTVs and early generation 4K Ultra HDTVs covers only 35% of the total visual color spectrum.
Note: Use a premium high-speed 18Gbps HDMI cable for the best 4K/HDR performance.
HDR (High Dynamic Range): The Yamaha RX-A870 support HDR (high dynamic range) Video - including HDR 10, Dolby Vision, and Hybrid Log-Gamma. HDR (High Dynamic Range Video) provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image. HDR reproduces a greater dynamic range of luminosity or brightness levels, creating greater contrast. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth.
- HDR 10: HDR 10 is an open standard and currently the most popular HDR format on the market. It uses static metadata at the start of a movie to tell the receiver and your TV that the video content is encoded using HDR.
- Hybrid-Log Gamma: HLG (Hybrid-Log Gamma) is primarily designed for live video feed and over-the-air broadcasts. It uses no pre-encoded metadata and is backwards compatible with SDR. HLG's native compatibility allows much of today's existing SDR infrastructure to be re-used for HDR in the future.
- Dolby Vision: Unlike HDR 10 which contains static metadata and HLG which uses no metadata, Dolby Vision uses dynamic metadata technology which sets individual color and brightness levels for each and every scene. Dolby works directly with filmmakers at major Hollywood studios to create superior HDR video masters of blockbuster movies.
Note: Dolby Vision and Hybrid Log-Gamma requires a firmware update.
4K Video Upscaling: The Yamaha RX-A870 AV receiver will upscale video signals from analog (480i only)-to-HDMI and HDMI-to-HDMI, up to 4K.

Previous good experience with Yamaha. This model's features. [ Brian Jan 21, 2018 ]
I have had a Yamaha receiver for ~18 years. It is awesome, but 4 moves across 2 continents takes its toll. Some connections are getting dicey. Still works, good sound through my system, but I want HDMI connections, Bluetooth headphone access and streaming. This unit seems to be a good replacement with the features I was looking for. I hope this one lasts another 18 years. [ Stephen Jan 14, 2018 ]

Most inexpensive. In the line with what I needed, pre outs. and it has dolby vision support, and good reviews. Was going for the Onkyo rz810 but was worried about the hdmi reliabilty and dolby vision support or possible lack of. Dolby vision on 4k discs is quite amazing [ Billy Nov 30, 2017 ]
I wanted an A/V receiver that could play audio in two zones, and also wifi for streaming [ James Oct 24, 2017 ]
My Marantz sr7005 died last night I need a quick replacement... I have had most brands since I was a teenager and I have never had a yamaha..I have known about this company for a long time and I know they are very reputable and I read good reviews about it...so I am giving it a try...my first choice was the denon x6300h or the yamaha rx1070, but i figured to start with this one first... [ Rey P. Sep 19, 2017 ]
Crutchfield expert recommendation... [ LaVenus Sep 18, 2017 ]
I use separate amplifiers, so I needed a reciever with multi-channel pre-amp outputs. I selected the least expensive receiver in the AVENTAGE line that included all the features I required. This saved me a good bit of money. The inclusion of 4k and dolby-atmos means I may not have to upgrade again for a long time. [ Robert Sep 15, 2017 ]
I purchased the Yamaha Aventage RX-A770 for a room that needs only one HDMI output. The unit has worked out great! Excellent sound quality with no boomy sound like competitor models. Video pass-through is excellent and supports the latest 4K standards, including HDR. The model RX-870 is upgrade from the A770, and has two HDMI outputs that will be needed for the room its going. I've tried Denon, Sony and Onkyo new models that came out in May and June. Not as good as Yamaha. I waited for the best! [ G Jul 06, 2017 ]

you will be fine with teh antenna only at a 60 degree angle. as long as your router is somewhat close by, you'll be fine. hope this helps. [ Nadia Mar 13, 2018 ]
Yes, this should still work. Touching glass should not lose an issue. You do need to be sure the amount of metal between the antenna and your WiFi router is minimal. [ George Mar 13, 2018 ]
Sorry, but as of today I haven't setup the receiver. it's still in the box. [ GABRIEL Jan 12, 2018 ]
1 answer Hello, In the beginning, please excuse my broken english, I'm not a native speaker. Because I want to combine the useful with the pleasure, I would like to buy a Yamaha RX-A870. At the same time I felt in love with analog sound so I would like to know how would I record a stereo sound from this AVR to an external Akai deck. Especially when I feed the AVR with multi channel digital streams like DTS, Dolby Digital, LPCM, AC3, DSD64/128 and a downmixing to stereo is a must. Another words, a stereo analog output can be configured ? Many thanks. [ Costin Nov 10, 2017 ]
Sorry, no. The Yamaha RX-A873 will not "downmix" a multi-channel digital input signal into a stereo analog audio output for recording.

Both the 870 & 1070 will support HDR Video including HDR 10, Dolby Vision, and Hybrid Log-Gamma. HDR-10 is supported out of the box and both Dolby Vision & HLG support will be added via a Firmware update. At this time, there is no ETA for the update. [ Ryan Oct 30, 2017 ] Staff
The best I could offer would be a guess, but I can tell you that I have been completely happy with my A-1070 and wouldn't change a thing. I considered the A-870 before purchasing and feel confident that you can't go wrong with either product. I'm on my third Yamaha receiver over the last thirty years and have never been disappointed.

1 answer according to the manual, you can have Atmos '5.1.2 + 1Zone' or '5.1 BI-Amp' configuration, but why can't it have 5.1.2 + BI-Amp? Technically it should be possible, because EXTRA SP1 is for bi-Amp, and EXTRA SP2 is for Front Presence (Atmos). So why doesn't the software allow this configuration? I want to have 5.1.2 Atmos configuration, but use bi-amp for front speakers. [ Ari8099 Aug 13, 2017 ]
A "5.1.2 + Bi-amp" configuration would require 9 channels of amplification, while the Yamaha RX-A870 receiver only offers a maximum of 7 at one time. When using the "Dolby Atmos + Zone 2" configuration and Zone 2 is OFF, all 7 channels from the receiver are directed to the 5.1.2 system. However when Zone 2 is turned ON, power to the Overhead/Dolby Atmos speakers will be cut off and directed to your Zone 2 speakers; limiting you to 5.1 surround in the main room. For more details or to discuss further, please feel free to contact an Advisor directly by phone (888.955.6000) or online chat. Thanks!

5 answers This may sound like a dumb idea/question, but I was thinking of using my TV's speakers for my center channel since it is mounted to the wall. My TV is a Vizio P65-E1. I also have a JBL SCS135 set of speakers for my other channels. Do these receivers have the ability to send the center channel signal over the HDMI cable so I can do this? It would save me from having to fish an audio cable through the wall. Thanks!! [ Blaine Jul 15, 2017 ]
Blaine, While I can appreciate what you would like to do, I personally think it's not worth even trying. My best recommendation is to talk with a Crutchfield technical support person about exactly what it is you would like to try and do-and get that person's opinion. [ David Jul 18, 2017 ]
The RX-A870 does not allow you to select which channels go out the HDMI port. You can only control if audio us sent out the HDMI port. [ George Jul 18, 2017 ]
No but I bought the A770 I have a 60" lg I don't know about your vizio speakers the ones in the lg are not very good you will be a lot happier with a good center channel speaker [ Michael Jul 17, 2017 ]
No they can not. [ JAMES Jul 17, 2017 ]
I moved from an Onkyo receiver to the Yahama A770 and its been amazing sound quality with no change to my speakers which are Polk center channel and bookshelves that I've had for almost 10 years (from Crutchfields). I don't think you can go with your proposed solution of using your TV speakers; nor, understand why you would want to after making such an investment in your TV. If you think about it, the quality of your TV speaker will come nowhere close to a decent center channel speaker. Furthermore if possible, I suspect you would blow out your TV speakers when watching any decent action movie. My suggestion is to get your bait and rod and go fish. You won't be sorry.
