Something JDanielP said on another thread got me thinking. I own a Yamaha DSPAX750SE with Mission M34is as my front floorstanders. From what I understand, JDanielP meant that the A + B ouputs on the amplifier can each be sent to the high and low frequency posts separately on each speaker. Is this really "pseudo bi-amping" and does it have any positive effects?? Common sense would suggest that there would be positive gains in two channel mode, as the amplifier would be able to send more power to the front speakers as it doesn't have to divide the power supply between any effects speakers, just the front "four". From this, logic would also suggest the effect would be negative in five channel mode as the power supply has to be shared between seven, rather than the normal five. I didn't know how else to describe it so I hope you guys understand me! Am I a complete numbnut??? Also, if this really can be done, would my Yammy and Missions be ok to do this with??? Sorry if this thread is pointless!!!!!
