JDS - when I run my test I assume you want me to change the amp settings from 7.1 ch (bi-amp) to 9.1ch. I'll have to run audyssey again I assume. But what am I hoping to find?
1) If your test works, does that mean that 9.1 is only possible when the amp is assigned to 9.1ch mode? In other words, I cannot bi-amp my main speakers internally and
process 9.1 channels at the same time? I'm beginning to think this is in fact the case given that the alternative amp mode is called literally called "7.1
ch (bi-amp)", so I'm guessing the receiver will process 7 channels max, and even if you are using an external amp for the 8th and 9th channel
2) if your test doesn't work, does that mean my receiver is defective?
If #1 above is correct, then does that mean the only way to get 9.1 processing AND bi-amp my front speaker is to bi-amp my speakers externally
. In other words, I'd have to (a) set the receiver amps to 9.1 mode (even though I will only be using 7 internal amps), and then (b) connect the L&R pre-outs to 4 external amps (each channel split into 2 with Y adaptors)?
