  • That large null at 80 hz that Audyessy is trying to correct is likey to be 1)the sub being out of phase with the mains2)and or crossover on sub itself set too low 3)A room induced cancelation do to subs location.
  • Apparently orange is the new black.

  • So then all is well Chris?

  • The Emo tech gave you great advice and the correct procedure to track down and eliminate ground loop issues. However I believe earlier you measured 14 ohms across the two negative binding posts with the ground lift switches in the ground position. I…
  • Your welcome Chris,good luck.

  • Yes double check with them that the amp does not have bridged out stages and can be safely strapped. That being the case you should get the desired result with the addition of a short piece of wire.
  • As long as the negative terminals are at ground potential, in other words it does'nt have a bridged /balanced output stage then you can strap the grounds together. That applies to dual mono and even separate mono bloc designs. Assuming done correctl…

  • 14.2 ohms from negative binding to negative binding post? If so the solution would then be to tie the two negative terminals together with a short piece of speaker wire.

  • Have you confirmed the amplifier is common ground? I would try another amp if you have access to one.

  • Indeed,and lower noise. Thank you.

  • Absolutely,you have two good amps so experiment and try both ways and see which you prefer.
  • Since you already have two identical amplifiers I would suggest using a "vertical " passive bi amp configuration as you alluded to in your first post. Vertical bi-amping means using one amp for each speaker. One channel to drive the tweeter the othe…
