Hi.
After doing some searching on the net i managed to find the schematics and also this place and the various threads it has about this range of souncraft related mixers and their issues.
I am hoping that someone may be able to offer some advice.
The mixer has been sat for a while since it had an issue. When powered on the mixer would work fine, but sound would only come out of the sub outputs. if i routed it to the main mix from mono there would be nothing, if from stereo there was a very quiet signal with the gain and faders up high, and also some slight popping/ crackles.
I have taken the mixer apart to see if there is anything obvious, the psu is good and the mixer condition is excellent. I have been told to replace the 5532 driver as that is a commmon issue, the full code on the ic is:
5532
6054b
jrc
the only other thing i can think of is prehaps the 072b op-amps also on the main sat down inbetween the faders.
I am hoping that either uk.rs or cpc have these in stock.
can you suggest anything else to check?, the insert jack contacts are closed properly and there are no issues there. I cannot see any caps blown or leaking.
The fact it works through the sub outs sureley means its at the main ouptut stage input point or in the stage doesnt it?
thanks
