The Bogen MAX1R Mono Aux Input Module is warranted to be free from defects in material and workmanship for
three (3) years from the date of sale to the original purchaser. Any part of the product covered by this warranty that, with
normal installation and use, becomes defective (as confirmed by Bogen upon inspection) during the applicable warranty
period, will be repaired or replaced by Bogen, at Bogen’s option, provided the product is shipped insured and prepaid to:
Bogen Factory Service Department, 50 Spring Street, Ramsey, NJ 07446, USA. Repaired or replacement product will be

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 levels of various devices so that the main unit controls can
be set to relatively 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
moduleʼs 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 unitʼs 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 itsʼ output. The range is adjustable from
no reduction in level to full muting of the output signal.

Connections

Uses a standard RCA connector to make connections to the moduleʼs
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 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 unitʼs 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.

Jumper Selections

Priority Level

*

This module can respond to 4 different levels of
priority. Priority 1 is the highest priority. It mutes
modules with lower priorities and is never muted.
Priority 2 can be muted by Priority 1 modules
and mutes modules set for 3 or 4. Priority 3 is
muted by either Priority 1 or 2 modules and
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 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 unitʼs 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
disabled. Detection of audio for the purpose of
muting lower priority modules is always active
regardless of this jumper setting.
