and Indicators

A. Dust Filter

Removes large particles from the air at the air intake. The filter elements can be easily removed for cleaning by gently pulling them away from the front panel.

B. Level Control

Rotary detented level control, one per channel.

C. Signal/IOC Indicator

Green LED, one per channel. Dual-pur- pose indicator illuminates to indicate the presence of input signals; flashes brightly with a 0.1-second hold delay to indicate a difference (distortion) between the input and output signal of 0.05% or greater; and flashes brightly with a 0.5-second hold delay to indicate input clipping distortion. See Section 4.1.2 for more about IOC.

D.ODEP Indicator

Red LED, one per channel, illuminates brightly to indicate presence of thermody-

namic energy. They dim proportionally as energy reserves decrease. In the event that energy reserves are depleted, the indica- tors turn off and ODEP limiting occurs. See Section 4.1 for more about ODEP.

E.Enable Indicator

Green LED indicates amplifier has been turned on and AC power is available.

F.Enable Switch

Amplifier is on when the switch is in the IN position.
