Question: When headphones are connected to PHONE on the front panel can I use remote to switch between my set of speakers and headphones?
Document: I bought this to replace my blown Yamaha vx 371. It was a breeze to set up and is also simple to use. I have this connected to 2 tower speakers and Infinity and JBL front highs and surrounds. Also have two subs hooked up to take advantage of all of its features. I'm not sure it pushes quite as much power as it says but the sound is crystal clear and very comparable to my previous Yamaha.
If using digital input just set to digital on sound field and everything should be fine. Sound field control is right next to volume on remote so it is easy to find you preference. The manual is typical sony confusion with back and forth page info, so spend some time on the manual before you even look at the receiver. Has mic for adjusting speaker levels works fine, but I still tweek rear speakers. Can use high and low front or second set of surround but not both at same time.
Seems to have ample power. Works with Netflix 5.1 DD+ from Roku 3. Remote fairly easy to use. FM works well.NEGATIVES: Front panel top buttons have small lettering and are not illuminated, making them hard to read. No Phono Preamp. Power consumption in Standby with Pass Through On must be high, since the unit runs warm in this mode. (The manual does not show the consumption in this mode. I finally turned it off.)
I have to pump it up to around volume 26 o get descent sound out of it but the quality of the sound is true surround sound. I love it. the on screen menu for the amp is a bonus too and the remote is easy to use. i like that this has the auto calibration mic but remember to reset the front speakers to small size so as to get lfe output from both subs.
With smart connected items no need to change input on the TV, the receiver  does it for you (through the receiver). The remote also has the buttons to chose input.3) The receiver does not have to be on to just watch TV. It has a pass thru ability to allow you just to watch and use the TV speakers only.
Okay, now I get it, 3 front, 4 surround, subwoofer. Seems like a dumb idea since they advertise the unit as being 7.2.The controller does not have a back light - bummer.Using a speaker switch to go from high fronts to back surrounds depending on the movie. Neat! I recalibrate the speakers each time I switch setup because I haven't found a way to save the different settings. That may exist, but I haven't found it (yet?
Once your TV is connected to the amp, use the included remote and access the TV display to setup your system. Works flawlessly and is very simple to understand.The one issue that puzzled me for a couple days was the speaker setup selection. The options are 3/4.2, 3/4, 5/2.2, 5/2, etc. Nowhere was 7.2 listed. Nowhere in the manual is this even dealt with.
Very pleased with the Receiver. I have all Sony equipment (TV and BlueRay) so everything auto connected without issue. The setup of the receiver with my speakers was very simple. The enclosed mic does an auto setup and when it failed it told me I didn't have front speakers. I checked my plugs and sure enough I had the speakers wired wrong. My old speakers sound much better with the new , higher powered Amp.
Look closely before you buy. While the sound of this Sony amplifier is very good, it only has ONE OUTPUT! That's right, ONE, and that's an HDMI. So if you want to use a set of wireless headphones to watch TV, forget it. Well, that's not entirely true.
I did not have this problem before when my BD player and PS3 were connected to a simple HDMI switch. I really wanted this receiver to work given the low price and features offered. All other features on this receiver work as good as my old STR-DE885.
Answer: There is no button on the remote that will let you switch different speaker sets.
