OPTRO 740 comp / EQ doc's / schemo's ? (WANTED)
Posted: Wed Oct 21, 2015 12:14 am
Hi folks.
I have an OPTRO 740 "Audio Processor" here (compressor / EQ unit) which seems to work OK in terms of the nice 10-band inductor EQ section, but there is a compressor bypass switch added on the back (along with attack and release time controls), and I suspect there's an issue with the switch, as I can't get the compression action kicking off so far, at all..
Hoping somebody out there might have some documentation for this unit, or even just a schematic, or anything really!
Cheers!
