It has LOTs of power, like you said, but also LOTS of noise relative to good $100-$150 headphone amps and a high likelihood of channel imbalance. The recent Audioscience Review test
[audiosciencereview.com] shows distortion at .012%, Noise at 78dB below signal, and about .5dB L/R channel difference at 5W (likely higher at headphone volumes).
By comparison the $99 Schiit Heresy has .0007% distortion, Noise 103dB below signal, no channel imbalance...and PLENTY of power for 99.5% of all headphones. Plus, the Heresy has an external gain switch, so you do not have to open the chassis anytime you want to switch between high/low sensitivity headphones.

You'll need a phono converter unless your turntable outputs rca.
You can hook a sub up to the line outs.
Rca out to subwoofer in. If your sub only has a single RCA, connect it to the white RCA only.

Shhhh... I got downvoted for saying the same thing 🙄
I'm not sure if you're mixing things up. If your saying your yamaha has preouts for adding additional speakers (eg. 5.1 vs 7.1 or 7.1 vs 7.1.2), then you can use this to power the additional speakers. although I would use this one for the mains and not tge atmos as this is a much better amp than the ones inside any receiver.

Chances are you will never hear the difference....
Thanks.
Yes. My Yamaha Avantage can power 9.2 OR 11.2 with preamp. So can I use this as dedicated preamp for front large floor standing and rest by Yamaha? So I can connect this with Yamaha amp.
Yup not much of a discount. 🤔🤔🤔
Ya old class D amps. That's why they first started out as subwoofer amps. Class D has come a long way since then. In blind A/B tests it's getting harder and harder to tell the difference.

You need an amplifier (not a pre-amp, that's the receiver's role here) for 2 speakers. This would work for that. (Presumably it would work quite fine, but i don't have one to give an opinion on)
I have a Marantz 6011 running in this configuration for 7.1.4 Atmos, using a tpa3116D2 as the amp for the two rear ceiling speakers, which is plenty for those at the levels we watch movies at (e.g. not shake the house loud). If bi-amping front speakers, or wanting louder listening levels, something beefier like this or like the tpa3255 based amp someone linked earlier would probably be a good choice.
Anyway, the "classes" of amplifier aren't a direct indication of quality, just of the electrical circuitry topology. Nothing makes a given class AB amplifier *arbitrarily* better than a given class D. A good modern class D can keep up with AB design amplifiers in terms of distortion/noise, all while wasting less energy into heat (they're generally far more efficient). The trouble usually is more in finding one that can do that at high enough power levels for the target speakers at a desired volume while retaining those characteristics. And of course, individual amplifier designs differ.
Emotiva usually has a good reputation for the price points they sell at, from everything I've heard. Equally, some tpa3255 based amps are notorious for quoting theoretical max wattage based on 48v while only coming with (and only really supporting) 36v power supplies. And the distortion curves on class D often favor not exceeding about 50% rated wattage (as a very, VERY loose rule of thumb), but it various on the chip used and the componentry of the surrounding design. But even 50% of the rated max output on a tpa3255 based design, running two speakers, is going to be plenty for most home listening setups, short of something built out to a degree where they would be expected to already know otherwise if it were the case.
