It’s not that big of a deal. You just use the tone setting on the AVR, and the remote sensor will gauge the level, and then the AVR will balance the sound of all the channels to be the same in relation to wherever you happen to have the remote positioned. Then you go into the settings and add or reduce sound levels of the different channels to your liking.

I tried it with my 7200 and ended up going back into the settings and doing it by ear. Really, don’t worry about it.

Another thought though, with either the 7300 or DP, you shouldn’t need another amp. I wouldn’t waste your money. The 7300 has incredible current.
