4 Operation (continued)

4.2Front Panel Controls 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. Filters can be cleaned by soaking in a mild detergent and water.

B.Level Control

Rotary detented level control, one per channel.

C.ILoad/ILimit Indicator

Dual-color LED, one per channel. Indicator is off when there is no significant load cur- rent (extremely low or no input signal, or no load connected to the channel's out- put); illuminates green to indicate that load

current is flowing; and illuminates red if the amplifier has reached its maximum output current capacity. See Section 5.2.3 for more about ILoad/ILimit.

D.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 5.1.2 for more about IOC.

E.ODEP Indicator

Amber 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 5.1.1 for more about ODEP.

F.Enable Indicator

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

G.Enable Switch

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

H.VZ Mode Switch

Four-position switch, one Per Channel. Allows selection of “VZ-ODEP,” “Lock Low,” and “VZ” power supply modes, from left to right (right-most two positions both select VZ mode). See Section 5.2.2 for more about VZ and the VZ Mode Switch.
