I believe it's a power level switch, not positive though.. if no one else comes up with anything by Monday I think I can look up the pinout for you then.

Ok, the slide switch is to select what type of PA microphone you use, it should be marked "M" for magnetic/dynamic and "C" for carbon/transistorized.

It says it will do 75 watts into an 11 ohm speaker, or 100 watts or more into two such speakers in parallel.

Connections are:

Pin 1 - +12Volts
Pin 2 - Ground
Pin 4 - Footswitch/horn relay
Pin 5 - Speaker
Pin 6 - Speaker
