NEWS: Yamaha announces new look RX-V4A and RX-V6A AV receivers

Some slight discrepancies. The V4 isn't actually Atmos enabled and neither will it be getting Atmos virtual height processing. Not surprising given the fact that it's only a 5 channel AVR. The YPAO calibration on the V4 isn't multpoint either.

Neither model includes analogue to HDMI conversion or indeed component/composite video inputs, but both include HDMI scaling up to 4K. Not that the latter is of any real importance to most people.

One interesting thing to note on Yamaha's own site is that they've started listing whether their receivers include Auro 3D. I'm therefore given the impression that some of their new higher tier models will be including this?

Another fact that some may find interesting. Yamaha appear to have forsaken Burr Brown and look to have ditched it in favout of Texas Instruments DACs onboard their new V series receivers? The V6 includes the 384 kHz / 32-bit BB PCM5102A while the V4 uses the 384 kHz / 32-bit BB PCM5101A DAC.


The 5 channel RX-V4A features 80W of power per channel while the beefier and more expensive of the two models, the RX-V6A is a 7 channel AV receiver with 100W per channel.
The power ratings are rather dubious. The rating for the V4 as given by Yamaha is actually 80 watts 6 ohms, 0.06% THD 2 channels driven while the V6's is 100 watts 8 ohms, 0.06% THD. Yamaha appear to be trying to portray the V4 as being more powerful than it actual is by rateing it relative to a 6ohm load as opposed to the same 8ohm load used to rate the V6?

The new models both incorporate a newly designed High Slew Rate Amplifier circuit which means they can adapt more quickly to rapid changes in input level and are suitable for high resolution audio signals.

Those pondering the importance of High Slew Rate Amplification may find this of interest:

The 485 was measured at 80W @ 6ohms in some countries last generation... and 80W @ 8ohms in others.
So I guess it depends on where you live!

From the RXV485 manual:
Rated Output Power (2-channel driven)
• [U.S.A. and Canada models] (20 Hz to 20 kHz, 0.09% THD, 8 Ω)
• [Other models] (20 Hz to 20 kHz, 0.09% THD, 6 Ω)
– Front L/R 80 W+80 W


I wonder if it will be the same for this generation?

I'm glad I've read this. I'm about to buy a Yamaha RXA 880 ex display.

Is it worth it or should I hang on till october for new models.

This has now changed my upgrade plans
Just need high models info to be related before I decide on a new receiver.!

Well done Yamaha giving your consumers what they want multiple 2.1 HDMI.

No no no... Sound United has told us this is way too expensive and nobody wants it!
I wonder if Yamaha have the same chipset (except sourced more) or did the go down the LG 2019 route and make a custom chipset so they could cover more ports. Or did they reverse Sound Uniteds implementation and go 2 ports in, 1 port out, a bit more clarification required

Custom chipset with an entire re-design of the internals was required according to one dealer. Apparently HDMI 2.1 boards are tricky beast s(not the doubling in the HDMI power supply) - ventilation is also the key, hence the side vents on the new amps + increased venting in general.

These are entry level Yamaha's, what the Aventage range has to offer will be interesting.

Yeah if you look at the heat sink on the new Denons 2.1 port, it’s massive ...

was close to pulling trigger on a denon X4700h - really close but this has made me stop. I always prefered Yamaha to Denon (well my ear does) i wonder when the high end ones are due, saying that a V6A might be enough for music/films and gaming. I can put the saved money on some new fronts, I have Wharfdale Glendales XP2 vintage speakers as fronts - Im looking at replacing for KEF's

Good to see Yamaha doing it properly, looks like I have found my new amp to replace my aging V677.

'Dolby Atmos Height Virtualization' sounds like marketing guff, but generally Yamaha's virtual setups tend to be pretty good, so looking forward to seeing if that makes any real difference or not.

Hopefully the prices see a bit of a dip after launch, £650 is a little bit steep, but I would imagine it will be closer to £500 by Black Friday.

I see that even hardware now is 'beta' on release.

I was going to pull the trigger on a denon 4700 which goes for £1,399 so £650 isnt bad imo

Finally officially announced. Liking the new look, and the V6A seems like a good match for what I am looking for, pre-outs for fronts, 7 channel, and HDMI 2.1 for future use. Will wait for when the firmware upgrades are released, and hopefully they will have come down in price a bit.

It is proprietory processing made by Dolby and already available onboard some AV receivers. It isn't something developed by Yamaha and was originally developed by Dolby for use with soundbars.

It can be effective, but isn't a serious replacement for actual physical height or ceiling speakers. Physical speakers will still give you the superior results.

These are entry level, phased launch so the mid to high end models will hopefully come at a later date.

No plans for a 9.2 / 11.2 variant?

These are lower end replacements for the RXV465 and the RXV685. THere are higher tier models destined to replace their Adventage RXA2080 and the RXA4080 flagship models.

The smaller LCD footprint is unfortunate, can show a lot of info, but from a distance will be difficult to see (mind you, phone app will show most info)

If the same iOS and or Android app as that which is currently available then it will not indicate what format is currently being received by the receiver. There's other info that isn't conveyed by the app such as channels present and speakers engaged.


Anyway, paint the volume dial red and you've got yourself a sad clown :lesson:

Another fact that some may find interesting. Yamaha appear to have forsaken Burr Brown and look to have ditched it in favout of Texas Instruments DACs onboard their new V series receivers? The V6 includes the 384 kHz / 32-bit BB PCM5102A while the V4 uses the 384 kHz / 32-bit BB PCM5101A DAC.
TI bought Burr Brown in 2000 so they're one and the same company. There's been a glacial phasing out of the Burr Brown name (although chips still have BB style codes) and this is most likely reflective of that.
