New member Username: DiplotocusPost Number: 10 Registered: Jul-04 | OK apparently this question is difficult because nobody I've met has been able to answer it. Here's the situation: I have a set of Polk LSi9 speakers (bi-ampable of course), and a NAD T773 7.1 receiver. Is it possible for me to use 2 channels on the NAD that I'm not using (probably the 2 rears) to bi-amp my fronts? I'm not sure if it would increase sound quality that much but I'm looking at it as a challenge. Also, I'm only going to build a 5.1 system, and the only reason I bought a 7.1 receiver is because NAD doesn't even make a 5.1 anymore. I'd love to get my money out of those 2 "dead" channels. Thanks for any help guys and gals. |

Just unplug the jumpers, get two 1xRCA->2xRCA slitter cables, plug them to left and right front preouts, and the other ends to left and right main-amp in and left and right surround-back main-amp in. Then just 'bi-wire' from L&R and SB L&R. Remember to remove the bridges from the speakers. |

Silver Member Username: LandrovalPost Number: 402 Registered: Feb-04 | You'll have to adjust volume differences so they will match. Other than that there should be no problems. I dont think it will double your power, it's not the same as bridging. It will have some affection to the sound, but not the same kind than doubling the power. AVSForums had a very long debate about this and I dont think they ever came to a solution. At least 2x100W is not the same as 200W. |
