Re: A-132-3 question

2011-01-20 by mfretton

Dear Dieter,

Both of the A-132-3 modules I have contain the SSM2164. If a modification is possible that would be great, but I would need clear layman's instructions as my understanding of electronics is minimal, although I can solder adequately.

So is it normal for the A-132-3 to continually pass low-level audio (as I wrote, the amount varies from each VCA)?

Thanks again for your help with this.

Best wishes,
Matt
