Module Front Panel Controls & Connectors

Maximum Gain

Sets the maximum amount of gain added. Range of 1 dB to 22 dB of added gain.

Activity LED

Bi-color LED illuminates when different thresholds are triggered to assist in setup.

Ambient Threshold Control

Adjusts the microphone ambient noise input threshold from 64 dBspl to 112 dBspl.

AUX Input

Mono summing, stereo, unbalanced RCA inputs. The input can be used as a normal input or set to bypass the gain adjustment process of ANS1R.

MIC (Sensor)

Connections to ANS500M sensor microphone(s) are made here.

Ramp Speed

Sets the speed by which gain is increased or decreased to the signal, from less than 1 dB/s (slow) to greater than 20 dB/s (fast).

Activity Threshold

Activity threshold is set just above typical operating level of the program material applied to the gain processing stage ANS1R.

AUX Level Control

Controls the input source level when internal jumper is set to Bypass mode (AUX signal bypasses gain riding).

Defeat

The effects of the ANS1R will be defeated when these terminals are shorted together.

Jumper Selections

AUX Input Signal-Processing Jumper

• The AUX input available on the module can be set to feed its signal to the amplifier’s front level control by setting the jumper in the “Normal” position. The signal applied to this input will eventually be

processed to the gain riding function of the ANS1R

like every other input installed in the amplifier.

• By setting the jumper to “Bypass” position, the AUX input will not be affected by any gain level changes

of the ANS1R.The amplifier’s front panel level con-

trol will be inactive when the module is set in this mode. Any AUX signal level adjustment must be made using the module’s AUX LVL control.

There are situations where it may be undesirable for

this AUX input to be affected by the gain riding function of the ANS1R. A typical exam-

ple would be where low level background music is desired in a lounge when there are only a few people present.When the lounge is crowded and the ambient noise level is high, it is not desirable for the background music level to increase since it will only add to the high ambient noise. This is a case where the AUX input “Bypass” setting would be appropriate.

Muting Jumper

Jumper placement only affects the module’s unbalanced input signal.The jumper placement determines whether the module’s input can be muted by other input modules or not. When enabled, the input is permanently set to the lowest priority level. When disabled, the module will not respond to mute signal and remains active continuously.

Module Installation

1. Turn off all power to the unit.

2. Make all necessary jumper selections.

3. Position module in front of desired

output module bay opening, making sure that the module is right-side up. Output modules will not fit in an input module bay. Do not force an output module into an input module bay.

4. Slide module on to card guide rails. Make sure that both the top and bottom guides

are engaged.

5. Push the module in to the bay until the faceplate contacts the unit’s chassis.

6. Use the two screws included to secure the module to the unit.

WARNING:

Turn off power to unit and make all jumper

selections before installing module in unit.
