B1 Mono output

bassnkeys · 20th August 2012, 07:49 PM

I would like to add a stereo / mono switch to my B1.
Has anyone done this?
How did you wire it?
Thanks,

You can put the switch across the clockwise positions on the two pots, but
this depends on the source impedance of whatever is driving the inputs.

If the source impedance is low (probably) then you want some resistance
in series with the inputs. Try 5K from the input RCA's to the board in
place of the red wires.
