I am wondering if you set bi-amp to Yamaha 663 and use front a speaker out to main speakers you have a choice for extra sp to be assaigned as front b. You can select on front panel if it to be front a > front b > a + b > none. My question is depending on selecting a or b or ab does bi-amp work or not? Example have one set that are bi-amped nad another set that is connected only on front b. Can that work or if I choose only front b there will be some sound from bi-amped surr back out? Thanks.
