Level Controls
The amplifier provides separate input level controls on the unit
front panel for rear inputs 1 through 4. Turn knobs clockwise
to increase, or counterclockwise to decrease levels.
Bass & Treble Controls
Bass and treble controls are located on the front of the unit to
provide tailoring of the unitʼs frequency response.
TEL Input Level Control
The volume level of the TEL Input is located on the rear panel
of the amplifier. Turn knob clockwise to increase, or counter-
clockwise to decrease levels.
LINE/MIC Selector Switch
Inputs 1 through 3 provide an electronically-balanced input
with selectable gain suitable for microphone and LINE/TEL
level signals.
- For balanced, low-impedance microphones, the switch should
be set to the MIC position.
- For balanced, condenser microphones, the switch should be
set to PP which will provide phantom power to the microphone.
- For balanced line-level or telephone-level signals, the switch
should be set to LINE. If using the input with an unbalanced
line-level signal, the switch should also be set to LINE (see
the section on input connections for instructions on unbalanced
input wiring).
Mute Send
The mute send switch is used to disable Input 1 from muting
Inputs 2, 3, 4, and Media Player. Set this switch to ON if voice-
activated muting of Inputs 2, 3, 4, and Media Player by Input 1
is desired. With this switch set to OFF, the amplifier will act as
a 4X1 mixer with no priority override. Note: the TEL input will
always mute Inputs 1-4 and is not defeatable.
MOH Output Level Control
The rear panel mounted MOH control adjusts the MOH output
level. Turn knob clockwise to increase, or counterclockwise to
decrease levels.
MOH Source Select
The rear-mounted source select switch allows either the Media
Player or Input 4 to be set as the source for the MOH output.
Only the selected source will play out of the MOH output
regardless of what paging/priority activity is happening in the
amplifier.
