Module Installation

Jumper Selections

1. Turn off all power to the unit.

2. Make all necessary jumper selections.

3. Position module in front of desired module bay opening, making sure that the module is rightside up.

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.

Gate - Threshold (Thresh)

Controls the minimum necessary input signal level to turn on the module’s output and apply mute signal to the main unit's buses. Clockwise rotation increases the necessary signal level required to produce output and mute lower priority modules.

Priority Level

This module can respond to 4 different levels of priority. Priority lower priorities and is never muted.Priority 2 can be muted by Priority Priority 3 is muted by either Priority mutes priority 4 modules. Priority 4 modules are muted by all higher priority modules.

* The number of priority levels available is determined by the

amplifier in which the modules are used.

Gating

Gating (turning off) of the module's output when insufficient audio is present at the input can be disabled. Detection of audio for the purpose of muting lower priority modules is always active regardless of this jumper setting.

Bus Assignment

This module can be set to operate in stereo mode, where input A audio is delivered only to the main unit’s A channel, and likewise for the B input. Or, the module can be set to combine the stereo into a mono signal and make it available to all buses within the main unit.

1 is the highest priority. It mutes modules with

1 modules and mutes modules set for 3 or 4.

1 or 2 modules and

Gate - Duration (Dur)

Controls the amount of time the output and mute signal of the module remains applied to the main unit’s buses after the input signal falls below the required minimum signal level (set by the threshold control).

Ducking (Duck)

Controls the level of the output signal from the module when it has been requested to mute/gate its’ output.The range is adjustable from no reduction in level to full muting of the output signal.

Gain

Provides control over the level of input signal that can be applied to the internal signal buses of the main unit. els of various devices so that the main unit controls can be set to relatively uniform or optimum levels.

Allows a way to balance the input lev-

Bass & Treble (Treb & Bass)

Provides separate controls for Bass and Treble cut and boost.The Bass control affects frequencies below Clockwise rotation provides boost; counterclockwise rotation provides cut. Center position provides no affect.

Connections

Uses standard RCA connectors to make connections to the module’s input. The inputs are quasi-balanced to reduce the chance of ground loops while still being compatible with unbalanced signal sources.

When assigned to separate buses, the "A" labeled input will feed signal to all "A" labeled controls and output on the main unit. Likewise for the "B" labeled controls.

100 Hz and Treble affects frequencies above 8 kHz.
