Absolute Phasing


I just purchased a B&K EX-442 Sonata Series amplifier and I am attempting to find if this amp is non-inverting or inverting. My search for the manual online was not successful. I am requesting assistance on this. Thanks.

It's a pretty conventional solid state amp, so I would be surprised if it inverted phase. That's an oldie but goodie.
"...Does it matter?..."

i most cases no but the Infinity Sub controller for example will pop if connected out of absolute phase. I know, I have two dead boxes right now. 
It matters if you have sub woofers attached to the same Pre Amp.
The main speakers could be potentially out of phase with the Subs.

Nope. Next spurious pseudo-reason?

try it both ways... go with the one with better bass response
This involves listening. People start doing that, next thing you know they're talking about what they're actually hearing. This is an audiophile site. Let's keep it theoretical, okay?
