AMPS CONTROL
HOW MANY SPEAKERS CAN YOU CONTROL
That is going to depend on the system. I don't fully understand the question, but my system (Denon) I can control each speaker. I can adjust the volume on each speaker. If I want the sound louder on a specific side or in the front or rear. Example my front speakers are turned lower 6db than the rear 12db beacuse they are on a wall next to our bedroom.
