WHAT IT DOES
PROGRAM INPUT
CLIP LED
Illuminates when the program signal
reaches 2 dB below clipping.
Gain Control
Adjusts the level of the program
signal. When you turn control fully
counterclockwise, no program signal
passes. When you turn this control
clockwise, the level of the program
signal increases.
MONO/STEREO Switch
Selects whether the PROGRAM INPUT
signal(s) will be kept separate (stereo
left and right), or summed to mono.
If you are using stereo left and right
inputs, set this switch to STEREO. If
you are using a mono program input,
or if you wish to sum both PROGRAM
INPUTs to mono, set this switch to
MONO. Using MONO, you can also
check the mono compatibility of your
stereo program.
