Channel Signal Lights
All four channels have a signal light which gets brighter as the signal gets louder. The color of
the light indicates the stereo content: blue displays the signal on the left channel, and green
displays the signal on the right channel. The signal light shows the signal post-fader (after the
Level knob). These lights are useful for determining which channels are active at any given
moment. However, they should not be used as precision indicators. For example, the green
lights will appear dimmer than the blue lights at low audio levels and brighter than the blue
lights at louder levels.

The panning curve has been carefully designed to achieve the perception of a sound source
being a consistent distance from the listener as it pans around.
Channels 3 and 4: Stereo inputs
Channels 3 and 4 each have left and right input jacks. Patching a stereo signal into these
jacks will accurately maintain the stereo image as the signal is mixed into the outputs. If you

The main outputs of the module are the left and right output jacks. The signal level on these

jacks are TRS 1/4" (6.35mm) and will output a balanced signal. Using a mono cable with
either jack will disable the balanced circuitry and a mono signal will be output. The switch
