Acceptable DC Volts from Bryston 4B


I have a Bryston 4B and am showing 0.0 DC Volts on the LH side and 0.037 volts on the RH side. I am trying to figure out why I have 3 woofers and 2 tweeters with no continuity between terminals and no visible signs of distress. Bryston says it is within the specs .... Ideas?

You're saying you have 37 millivolts on the right channel?
Doesn't seem outrageously high, but it does raise a flag.
What did Bryston say the spec for d.c. offset was?
Am I correct to assume that the 3 woofers and 2 tweeters were all being driven from the right side?
If your pre-amp/source is sending too hot a signal to the power amps front end, you could be driving them into clipping which can blow speakers pretty easily- especially with ss amps you could probably arc-weld with ;)
Speakers could also be blown by low frequency pumping if playing vinyl through a preamp that will reproduce low frequency in the range of 0-10 hz range.
