Hi there. I have a Yamaha rx v675 and I just use it for music.2 speakers outside on Zone 2 and 2 speakers in the house.One in the kitchen and one in the bathroom. Works fantastic with the Yamaha app. I have the Kitchen and bath hooked up to the Front speakers.There's no way to have just the kitchen or bath on,I don't see a balance control on the app. Heres what i was thinking. Could i just have the Bathroom hooked to right or left front and the kitchen on a surround.Then when i hit 7ch stereo both come on,and when i hit 2ch stereo just the Bathroom comes on?would it hurt the receiver that way or do you guys have a better suggestion.I want to be able to control it from the app which I love..thanks a lot
