AV-405 Difficulty

Post by drewideth » Thu Nov 13, 2003 1:36 am

In my smaller theater room I am using an Av-405 for the top end of a 5.1 system and the surround channel fails and puts the amp in protect. So I pull the surround output stage out of the chassis (disconnected from the power supply) and the amp works fine for the three front channels. So, of course, that tells me that output stage is bad. I've been through it at least ten times and a couple of audio engineers I know have been through it and can't find a thing wrong with it. Has anyone heard or experienced such a problem?

If it's not in the output board, it has to be in the speakers or wiring. (I would have checked that first! :D ) try swapping the output board for the surrounds with the output board of the center and see which one goes into protection... :idea: .... if any.
