Having said this, let’s dive in to uncover this new RX line, especially the RX-V6A, to see if its indeed the best choice for you.
Yamaha RX-V6A Features
Only once in a while do we see manufacturers change things up with something a little stylish. For decades now, most home receivers are usually of similar shape and design, which aren’t pretty, merely practical.
They are often made as black boxes with sharp- corners and a central blue-green dot matrix displays and volume knobs to the right. But Yamaha has come to challenge this with its simplified sleek, and modern design of the RX line.
The Yamaha RX-V6A comes in black color, with a curved front, bold volume control at the center, and high-resolution off-set LCD, although still blue-green. Also, it has the USB and phone jack on the front panel for easy and quick accessibility.
Other ports on the front panel include the power and remote sensor button, zone, pure direct, enter, YPAO jack, and a touch panel. However, the visibility of the character on display can sometimes deteriorate by the LCD characteristics under low or high temperatures.
Now, to the rear panel, which is regarded as one of the most vital parts of every receiver. The back panel consists of a trigger out jack (eARC compatible), wireless antennas, HDMI out jack, phono input, 7 HDMI inputs with 3 which are 8K compatible. This is quite impressive.
Also on the rear panel, there is a pre-out jack for connecting to a subwoofer or external amplifier, zone out jacks for outputting audio and external amplifier used in another room, a network jack, antenna jack, power cable, 5 audio jacks, and 8 speaker terminals.
The area around the video/ audio output jacks is marked in white to aid proper connections.

MOVIES: LIKE NEVER BEFORE
HDR and HDR 10+
HDR expands the range of both color and contrast significantly. It expands color, brighter parts of an image become brighter, so the image seems to have more depth. HDR aims at showing more realistic images with more contrast, color, and brightness than before.
HDR10+ is an advanced, improved version of HDR. It takes lifelike colors and contrasts to a new, dynamic level. It uses frame by frame metadata to improve scene characteristics between bright and dark so that essential data can remain. This helps in the production of more realistic content, exactly like the creator’s intention.
RX V6A has HDMI 2.1, which supports all the basic elements of video, ranging from resolution to frame rate, color depth, color space, and brightness range. It also supports end to end, 4K resolution and higher refresh rate for a seamless Integration with the HDMI ecosystem.
It also supports 8K resolution (7680×4320), the highest resolution at present. It delivers a super immersive viewing experience, doubles the horizontal and vertical resolution of 4K. And with a 60Hz refresh rate, it enables sharp, uninterrupted viewing of content with high-speed action.
RX V6A can display 4K UHD at a higher refresh rate, [email protected], compared to [email protected] This results in less motion blur and an overall sharper image. Your movies, games, and sports are in for a significant benefit.
It also supports the latest color spaces, such as BT. 2020 with 10 or more bits per color at higher frame rates.
Cinematic DSP 3D
This unique technological feature is solely owned by Yamaha, which adds richness and depth to your music and movie track. It was created by combining digital signal processing with measured sound field data.
Cinema DSP 3D allows you to create a sound field like actual concert halls or movie theatres in your room. Enjoy a natural three dimensional sound field right in your room.
THE BEST GAMING EXPERIENCE
You can now experience the best gaming experience with RX V6A. No longer do you have to experience the disappointment from trying to enjoy your new game on a system that doesn’t support the latest advances in visual effects, refresh rates, and surround sound.
RX V6A is here with its ability to support PS5 and X-box Series. Considering its features, It offers a significant gaming advantage over it’s Denon and Marantz rivals: Multiple high-bandwidth HDMI 2.1ports. Read our review of Yamaha TSR-7850.
Besides the three 4K/120Hz HDMI’s it has, which means you will be able to connect your Xbox series X, PS5, and high-end PC to the receiver simultaneously (using the various ports) rather than manually switching console connections over like you would if you want to route more than one next-gen console/ PC at a time through Marantz or Denon.
It also supports other game-specific technology such as Variable Refresh Rate (VRR), Quick Frame Transport (QFT), Quick Media Switching (QMS), and Auto low latency mode (ALLM).
Variable Refresh Rates
To understand the importance of this, Imagine you’re playing a video game on a PS5 connected to your HDMI 2.0 capable receiver and TV. You’re running along with a clip, and the game consoles video processor is sending new frames to your TV sixty times/Second (60Hz).
But suddenly, you enter a new place where your action gets very intense, and for a brief second, the processor can’t crank out new frames at 6oHz. This results in a simultaneous display of two different frames on your screen, called screen tearing.
And sometimes, you might see a stuttering effect as the display repeats the last frame it received until it is ready for a new one.
Variable Refresh Rate (VRR) prevents this; it flips the script. Allowing the refresh rate to be dictated by the sound device instead of your device. It eliminates judder, lag, and frame tearing for better-detailed gameplay.
VRR can change the frame rate to synchronize with the outputs of the GPU through the HDMI chain. So if your gaming console needs to slow down or speed up momentarily, a device that supports VRR will be able to do so without introducing tears or judder.
Auto Low Latency Mode
Another interesting way this technology influences your gaming experience is through it’s Auto Low Latency Mode.
This is often referred to as game mode, which is previously done manually in which you go through menus and settings to turn off specific video processing and other features to reduce latency as much as possible. You then switch it back to again for normal viewing.
ALLM enables this to be done automatically. It sends a message to your console that says, ” Hey, switch to that mode while I’m playing and turn it off when it’s time to watch TV or movies.
Quick Media Switching and Quick Frame Transport
Other specific gaming technologies provided by HDMI 2.1 include Quick Media Switching (QMS) and Quick Frame Transport (QFT).
These features enable seamless motion and transition for gaming videos and movies. However, these features will be available via a future firmware update.
POWERFUL SOUND PROCESSING
Envelope yourself in a melodious voice, feel the beat and tone of every music you play all around you, just like you are before the artist in a live performance, right from your room. RX V6A supports Dobly Atmos, Dobly Atmos Height Virtualization (via future firmware update), and DTS: X for more enveloping home theatre sound.
Dolby Atmos and Dolby Atmos Height Virtualization
Feel every dimension in Atmos. Experience sound in the 3D form with a 5.1 surround speaker set up and two Dolby elevation speakers or two additional overhead speakers delivering dramatic overhead effects.
Even for those without inceling speakers, you aren’t exempted. You can still enjoy sound in its 3 D form with RX V6A. Dolby Atmos Height Virtulization technology can create an illusion of height effects, stimulating the Atmos experience. It works by applying height cue filters to overhead audio components in the surround sound mix.
And if you do not have the speaker configuration for Dolby Atmos, yet want to enjoy multi-dimensional sound “that moves around you as it would in real life,” you can still do this with the standard speaker configuration you have already. Thanks to the RX V6A DTS:X feature.
DTS:X is flexible and will work with any speaker configuration within a hemispherical layout. It can support up to an 11.2 channel and 32 speaker locations. The spatial remapping engine of DTS Neural: X offers heightened realism and immersion for your favorite songs.
Connect with your Music
This receiver with 8k HDMI supports the majority of audio formats available. Whether it is MP3 /WMA/MPEG-4AAC: up to 48kHz/ 24-bit, FLAC up to 384kHz / 16-bit, ALAC up to 96kHz / 24-bit WAV / 32-bit, DSD: up to 11.2 MHz /AIFF: up to 384 kHz, RX V6A has them all. Enjoy your favorite music, the best way you can.

If you prefer the endearing familiar sounds of vinyl records, this receiver has a phono input for your turntable. And if what you like is to listen to music from free internet radio, we’ve got that too.
Multi-room Audio: MusicCast and Zone 2
The RX V6A works with the MusicCast, which wirelessly connects compatible Yamaha components for seamless whole-home audio. Customize your music, create favorites, and more using the MusicCast app.
Imagine sharing the music you love throughout your home or sending a different song from the AV source playing in the main room to another room. For example, if you have speakers installed in your bedroom, kitchen, and living room, with the living room being the main room with the receiver.
You can play a song in the living room and enjoy that same song or anyone you choose in other rooms. This is possible with Yamaha RX-V6A because it features MusicCast and Zone 2 compatible speaker terminals.
Compressed music enhancer
Yamaha compressor improves the performance of compressed music formats from MP3, WAN, Bluetooth, streams, etc. It brings the sound to be as close to the original as possible.
When music is encoded into digitally compressed formats like MP3, the frequency suffers. Music enhancer restores this, especially the low frequency sounds like bass.
Enjoy Music in its pure form
Pure Direct Mode is another feature offered by Yamaha. When it is enabled, it bypasses the sound processing and feeds the amplifier with sounds directly. This results in more realistic sounds. Making it a more enjoyable- Enjoy music in its pure form.
CONTROL: JUST BY YOUR VOICE
Hey Siri, play music in the bedroom and living room.
Explore the world of music. Stream multiple songs, including your favorite songs, all by command. AirPlay 2 aids streaming of songs from Apple Music, Pandora, Spotify, Tidal, and more. You can easily control this from your iPhone, iPad linked with a Homepad, or ask Siri via airplay to help you out.
Ask Alexa or Google Assistant
V6A is compatible with Amazon Alexa and Google assistant. They can help you with your music search, streaming it across different rooms. And even control volume, switch inputs, and playback on the receiver.
However, a third party is needed to initiate the command.
THE BEST ROOM CALIBRATION
If you’re familiar with Yamaha’s product, you’ll know that Yamaha uses Yamaha Acoustic Parametric Optimiser (YPAO) for its room correction and calibration. YPAO analyzes your room acoustics, measures speaker characteristics, and optimizes them to ensure the best surround sound for your receiver.
YPAO does this by measuring and setting speaker delays and speaker levels/volume. It also measures the frequency response of speakers and uses the PEQ (parametric Equaliser) to match the timbrel of the speakers to each other.
YPAO R.S.C (Reflected Sound Control) is more advanced; it allows YPAO to tackle peaks and dips by removing the first reflection of speakers in the room. Calibration with RSC ensures a uniform frequency response of loudspeakers in your room. It calibrates audio parameters to achieve optimum sound at upto eight sitting positions.
All you need to do is to place the supplied microphone at your listening position and switch on YPAO. It does this calibration automatically; you don’t need to go through the stress of measuring and measuring to ensure your room as the best of sound. YPAO automatic room calibration makes life easier.
You don’t need to get worried or confused about set up. Yamaha has done the more massive chunk of the work already.

The Yamaha RX-V6A is a great receiver that offers so much at such a low price range of $$$-$$$. First of all, it’s design is unique, modern, and attractive. Although attractive the visibility of the character on display can sometimes deteriorate by the LCD characteristics under low or high temperatures.
And when it comes to features and functions. You can’t but just exclaim, “WAO,” No one puts you in the center of action more than RX V6A. From recreating a live concert setting to an immersive home theatre experience and thrilling game console. All these from a near entry receiver.
It supports the latest technology trend such as HDMI 2.1 with VRR, QMS, QFT and ALLM, HDR10+, eARC, Dolby Atmos, Dolby Atmos Height Virtualization, amongst others. It’s compatibility with both Ultra HD TV’s, 4 K TVs and emerging 8K is impressive.
However, most of these functions won’t be present at launch but would be enabled by a future firmware update.
The downside to this receiver is its lack of some basic connectivity options like component video output/input, composite video output/input, Analog audio output, etc. Also, it doesn’t support the Auro 3D audio format and the Anti Resonance Technology wedge incorporated in some other Yamaha Speakers.
I’ll close with this; if you’re just getting introduced into the world of receivers and would love to get a receiver near the entry-level, this one is your best bet.
If you also want to get a quality receiver with a low budget of about $$$-$$$ and still enjoy the latest tech development, this is also for you. You won’t find a better receiver with as many recent tech features for this price range anywhere.
If your budget is a bit lower, let’s say $$$-$$$, you can go for the RXV4A, which was released alongside RXV6A. It supports HDMI 2.1, HDR 10+, and Dolby Vision. However, it is a 5.1ch, 80 watts receiver. RX V4A, when compared to the RX V6A, lacks DTS:X and Dolby Atmos Height Virtualization Technology, but is excellent for its price range.
Thes receivers will be launched this month of September, and trust me; I can’t wait to lay my hand on it to explore. I hope it’s the same with you.
