Hi i own me one of these awesome amps and i read in a review that it can be used to power amp your speakers by doing the following Bi-Amp Configuration of Main Channels Step #1: Connect a pair of analog RCA cables from the preamp outs of the "Front" channels to an unused input of the AVR-5803 (In my case, I chose VDP). Step #2: Select the chosen input as the source for Multi Zone 2. Step #3: In the Multi Zone Control menu, select power amp assignment for "Multi Zone 2". Step #4: Using the internal test tones of the AVR-5803, position the SPL meter (slow response, C-weighted) at the listening position and increase the master volume control until each speaker reads about 75dB. Step #5: Disconnect the speaker level connections from the "Front" channels at the AVR-5803 and reconnect them to the appropriate "Multi Zone 2" speaker level connections. Step #6: Repeat Step#4 while varying the "Multi Zone 2" volume level. I found nearly unity gain correlation between the "Front" channel and "Multi Zone 2" amplifiers to be at the "Multi Zone 2" volume level setting of +2dB. Step #7: Remove the jumpers on the back of the main speakers (you would be amazed at how many people forget to do this, Yikes!) Step #8: Connect a set of wires from the "Front" channels of the receiver to the highs section of each of your front speakers and a set of wires from the "Multi Zone 2" channels of the receiver to the lows of your front speakers. Now i dont have 6.1 or 7.1, so that aint a issue, was wondering have any of you lads tried this and if you have was there a difference in your opion. The reason i am thinking of doing this is because at the mo i am biwired and i find the treble when biwired to be slightly too much on some cds. Does that sound about right, cos last thing i want to do is damage my amp. I have been a long time reader of these forums so hi everyone !! I am sorry for any spelling mistakes or grammar mistakes but i am tired.
