CONTROLS & INDICATORS – FRONT PANEL

FRONT PANEL DIAGRAM

POWER SWITCH

The Power Switch is located on the front of the unit, directly in the

center. During initial installation, make sure the attenuators for

channels one and two are set to a low volume level before applying

power.

CHANNEL ATTENUATORS

The dials for channel one and channel two’s volume attenuators are

located to the left and right of the Power Switch. When set to zero (fully

clockwise), there is no attenuation of volume. As the attenuation

amount increases by turning counterclockwise, the volume is reduced.

Full attenuation is at - infinity. The attenuators are 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 clipping. This LED comes on

when the output signal from the amplifier begins to distort. When there

is significant clipping, lower the input gains to reduce clipping, as well

as the risk of damage to the speakers/monitors.
