RM20B Info: Standby / Silent / Live

[2012]

The RM20B has a very cool, yet undocumented feature: a BUILT IN DUMMY LOAD

The standby switch has 3 settings:

Standby: power stage is OFF & internal speaker is OFF
Live: power stage is ON & internal speaker is ON
Silent: power stage is ON & internal speaker is OFF

Also, the Line Out and FX Loop are unbalanced.

"when you put the amp in silent mode it puts a dummy load on the power amp stage. If you want to use another cab, switch the amp to silent mode, plug the cab into the EXT cab jack on the amp, and you are good to rock." - Rich Shelby @ Randall

It's cool but seems to have one disadvantage....you can't use the stock speaker at the same time as an external cab :-/

This might be outweighed by the ability to just plug a mic cable in for silent recording.

BTW Can I have a copy of the RM20B manual? Is it PDF? I didn't get one with mine

Shoot me a PM w/ your email address about the manual and I will send you a manual when I get back to the farm on Monday.
