Mesa's Stereo Power Amps

Post by JammyDodger » Tue Nov 16, 2021 2:04 pm

Hey All,

I think this would be applicable to all of Mesa's stereo power amps but I am specifically asking about the 20:20.

If I am using just one channel do I need to terminate the other? It seems strange to me that they did not design these to have it operate with just a single channel on. I wouldn't think must people have stereo cabinet set ups. Am I missing something?

Cheers, Mike

To All,

I found the answer, right in the owners manual strangely enough!

Turn unused channel volume to zero and Presence control to 10.

Some ppl I heard just remove the 1 amp fuse of unused channel. I think it just keeps it in stand by. Not sure if this is healthy for transformers though. Cheers and blessings. Jim
