I am using the ability of my receiver to reassign unused amps from surround rears to biamping the fronts. Having done this, I now feel that my midrange is slightly overpowering when listening to CDs, even after rerunning the setup mic. I haven't A/Bed it, so could well be imagining it, but on some songs the vocals seem disproproportionately loud. I suspect that this is due to an overlap of the frequencies being delivered to the high and low speakers. On the plus side, I have found a new joy in cymbals.
I was hoping someone could explain how the receiver determines what frequency band to send
to which internal amp. It's not really made clear in the manual as to which outputs are used for highs and lows, either - I have assumed that it is the ones labeled biamp that I connect to the top bindings on my speakers.
