Gain
Provides control over the level of input signal that can be applied to the
internal signal buses of the main unit. Allows a way to balance the input lev-
els of various devices so that the main unit controls can be set to relative-
ly uniform or optimum levels.
Bass & Treble (Treb & Bass)
Provides separate control of Bass and Treble cut and boost.The Bass control
affects frequencies below 100 Hz and Treble affects frequencies above 8 kHz.
Clockwise rotation provides boost; counterclockwise rotation provides cut.
Center position provides no affect.
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.
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 reduc-
tion in level to full muting of the output signal.
Connections
Uses a standard RCA connector 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.
Module Installation
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 right-
side 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 mod-
ule to the unit.
WARNING:
Turn off power to unit and make all jumper
selections before installing module in unit.
Jumper Selections
Priority Level*
This module can respond to 4 different levels of pri-
ority. Priority 1is the highest priority. It mutes mod-
ules with lower priorities and is never muted. Priority
2 can be muted by Priority 1modules and mutes
modules set for 3 or 4. Priority 3 is muted by either
Priority 1or 2 modules and mutes Priority 4 mod-
ules. Priority 4 modules are muted by all higher pri-
ority modules.
*The number of priority levels available is determined
by the amplifier the modules are used in.
Bus Assignment
This module can be set to operate so that the mono
signal can be sent to the main unit’s A bus, B bus, or
both buses.
Gating
Gating (turning off) of the module's output when
insufficient audio is present at the input can be dis-
abled. Detection of audio for the purpose of muting
lower priority modules is always active regardless of
this jumper setting.
