I thought i would share my weirdest and most difficult audio problem in the 15 years that i have been part of the hobby.
I upgraded simultaneously to:
DHC-80.3
Second hand King Cobra XLRs
Dual Sherbourn 5/1500A 9 channels used,
Feeding my old Paradigm Reference v.2 top
7.1 system, biamped Studio 100v.2.
Problem: random, totally unpredictable timing R tweeter
buzz, then dropouts, then silence, then back to normal, totally
unpredictable. Could go hours without it at times, other times
it would come on at startup or minutes after start.
Diagnostic path:
1. Switched amp channels, then interconnect, FAIL
2. Swapped tweeters, FAIL, problem did not transfer to L.
3. Opened Paradigm crossover, cleaned up contact, contact paste, FAIL.
3. Swapped speakers, R to L fed by interconnects from the other side, problem transferred!!!
4. OK, so now I am pulling my hair out, a master reset on my tweaked
processor would put me days behind. So I opened it, all connections solid,
closed, went into the "Speaker Setup" menu and swapped several times between
"Bi-Amp" and "Normal" and did notice that the relay click got louder the second
time i switched, then stayed the same.
Now 2 days without any buzz, or dropouts.
Thoughts? Bad relay, jammed relay, wtf happened? All i know is that i had the toughest two weeks and i am now much relieved, but still puzzled.
