I recently purchased a pair Edifier S1000DB (powered) speakers and a Yamaha AV Receiver RX-V385 because I wanted to get a system that I could use for HiFi as well as surround sound, should I choose to purchase more speakers. The trouble is that even with the manuals I am at a loss to know how to combine all of them to create one system and I think that in my haste, I may have speakers that are incompatible to the Receiver; can anyone help me to resolve the issue?
