Hello! I'm a new RMB1066 owner and I have some questions that I hope someone can answer. Question 1a: I've seen a lot of people quoting the output from the Rotel RMB 1066 as 6x60, 5x70 or 3x150W. Where does the 5x70W figure come from? I can't find it in the manual. It is my understanding that the RMB1066 has three 2-channel amplifiers (marked A, B and C), all bridgeable. I don't understand the 5x70 rating. Question 1b: I also wonder how you set the RMB1066 for "5 channel mode", the only way I've come up with is to set one amp in bridged mode, thus having 4x60W + 1x150W. Or is there another way? Question 2: Is there a problem with running the amp in 6 channel mode but only connecting 5 speakers? The reason I'm wondering is that I'm currently using 5 speakers with the RMB1066 in 6 channel mode (all three amplifiers in stereo mode), I can't bridge the amp for the "lonely" speaker since it's a 4 ohm speaker. Question 3: If I want to add a 6th speaker (center back), can I mix a 4 ohm speaker and a 8 (or 6) ohm speaker on the same amplifer? My current front center is 4 ohm, I'm thinking of buying a small wall-mounted back center, the only way to connect it would be to the same amp as my front center.
