Hi-
My understanding is that the switch in the rear can be wired for a number of functions.  I bought this amplifier second hand and I was wondering what this switch was wired as.

I regret selling my rm9, but these amps are currently making music with some La Scalas.

Generally a Mono/ stereo switch, looks like that is what yours is doing, too.

I talked with Roger.  If the switch points to the RCA inputs, it's stereo, the other way mono.
