This switch is to supply Power to equipment.
When power is on, power LED is lighting.
This LED indicator is to show excessive
input signal.
This LED is lighting when the input signal reaches
a level 3dB below the output clipping level.
This LED indicator is to show input signal
present at the channel input.
This controller is to adjust input signal gain
from -16dB to -60dB.
This button is to select Master output channels.
This fader is to control mixing level of input signal at each
input channel. Please minimize the faders of other input
