CONTROLS & INDICATORS – FRONT PANEL

POWER SWITCH

The Power Switch is located on the front of the unit, directly in the
center. During initial installation, make sure the level controls for each
channel are set to a low volume level before applying power.

CHANNEL LEVEL CONTROLS

The dials for the four channel level controls are located to the left and
right of the Power Switch. When set to zero (fully clockwise), the level
is at maximum. The level is reduced as you turn the control
counterclockwise. Full attenuation is at – infinity. The level controls are
detented and calibrated in dB.

SIGNAL INDICATOR LED

This LED indicates that a signal is present. The LED will glow when the
amplifiers output signal is within approximately 30dB of full scale.

CLIP INDICATOR LED

This LED indicates that the power amp is near clipping. This LED
comes on when the output signal from the amplifier begins to distort. If
there is significant clipping, lower the input levels to reduce clipping, as
well as the risk of damage to the speakers/monitors.
