INSTALLATION
Figure 1 shows volume control locations,
microphone and auxiliary input connections.
Figure 2 shows output terminal strips and
switches on the back of the mixer. Figure 3
shows a typical connecting arrangement. The
V-9985 contains a Main Mixer Module and 1
Remote Module. Three additional remote
modules may be connected to the main mixer
module. Figure 4 shows other feature
connections. Figure 5 shows Remote Input
Module, Speaker and Power Connections.
All connections should be made to the mixer and
double-checked prior to connecting DC power.
Connect the microphone to balanced XLR cables
and the microphone XLR connector on the
Remote Input Module. If the microphone is a
condenser type it will require Phantom Power.
Turn “ON” the Phantom Power Switch located on
the Remote Module using a small scribe or paper
clip. The Phantom Power LED will illuminate.
The microphone volume control is located on the
remote module. Other sources such as CD and
MP3 players, tuners, and computer sound cards
may be connected to the auxiliary inputs located
on the remote and main modules. Volume
controls for the auxiliary inputs are located on the
remote input and main control module.
An additional audio input is available with a
volume control located on the PC board for
connection to a low level audio source such as a
telephone page port o Valcom One-Way Page r
Control. An option dip switch located on the PC
board enables the input to override the
microphone and auxiliary inputs.
A compressor is available to even out a user’s
voice to compensate for poor microphone or
vocal technique and allow more microphone gain
before feedback. All auxiliary and microphone
inputs are routed through the compressor when
enabled. An option dip switch located on the PC
board enables the compressor.
