9. Cooling Vents - These vents are used for proper cooling. Never
block these vents and keep them clean at all times.
10. Channel 1 Gain Control - This rotary knob is used to control the
output signal of channel one. Turning the knob in a clockwise direction
will increase signal output.
11. Channel 1 Signal Indicators - These green and yellow LED’s will
glow according to the average signal output.
