LEFT/RIGHT OUTPUT MIC/LINE: DIP switches 1 and 2 adjust the left and right outputs for line- or mic-level operation.

MIC 1/MIC 2 Ducking: When ducking is on, the SCM262 will automat- ically lower the gain of all STEREO inputs when someone is speaking into one of the microphones.

DUCKING LEVEL: Adjusts the amount of STEREO channel gain re- duction when ducking is activated.

STEREO 3 JUKEBOX MUTE: This DIP switch turns the Juke Box Mute feature on or off. When on, any source connected to STEREO 3 will mute STEREO 1 and 2 inputs.

PHANTOM POWER: When in the down position, this switch activates a 12 V phantom power source for condenser microphones. Phantom power does not affect the operation of balanced, dynamic microphones, so one can be connected to the SCM262 in combination with a condenser microphone.
