INTRODUCTION
Your high fidelity desk microphone provides high
quality, low noise single and multi-zone paging
capability to existi ng paging products. A cardioid
electret element suppresses background noise,
and is housed on the end of a flexible tube. You
can page through a momentary push-button for
short pages, or make a long page with a lock-on
button. Front panel LEDs indicate paging status
(see Figure 1).
The back panel is shown in Figure 2. An attached
wall socket transformer provid es power to the unit.
Connections for tip and ring, busy buss, and dry
contact closure are made at a compression scr ew

level by screwdriver. The multi-zone model has a
switch for selecting dedicated single zone paging.

INSTALLATION
The microphone has rubber feet for placing
directly on a desktop. Connect the transformer to
a standard 120 VAC 60 Hz wall socket. Figure 3
shows the wiring connections at the microphone
terminal block. Multiple microphones may be
wired to an amplifier in either a st ar or daisy chai n
configuration, as shown in Figure 4. Choose the
configuration that minim izes the length of wiring
runs.
Figure 5 shows the wiring diagram for connecting
microphones to a PagePac D-Series Ampli Center
amplifier. An additional terminal block is recommended with the star configuration for connecting
the various incoming wires at the amplifier end.
