Got a Mesa Boogie Triaxis that has four switch outputs that can be used to switch different functions on Mesa power amps.
Supposedly just a tip to ground switch from (4) 4N30 opto's, one for each switching jack output.
Well, none of them are switching, no control voltage change to the opto's.
Anyone run into this problem? The schematic doesn't have these switch outputs included.
Front panel LED's say the switches are on, so I'm not sure if it's hardware or software related.
Factory reset didn't help.
Thanks.
