Many many channel of processing can the 3312 do? I'm not talking about amplification channel (I know it has 7 amps). Can it do 11.1 (7.1 with DSX wide and height) or 9.1 (minus off the heights) processing? I'm wondering if it can process it, then send the 7.1 through the preamp output, while amplifying the height and wide on its own. Just wondering the type of configurations that we can have. 7.1 + DSX Wide would be nice.
