PAGE PORT PREAMP/EXPANDER
INTRODUCTION
These instructions contain the specifications and
information necessary to install, operate and maintain
the V-1094A Page Port Preamp/Expander.
SPECIFICATIONS
Design
The Valcom V-1094A Page Port Preamp/ Expander is
a solid-state audio preamplifier. The unit comes with
its own surface mount box, which provides ½ inch
conduit access. The amplifier will accept a high
impedance input (600 Ohms) and reduce it to a low
impedance output. When the control knob is set on 5,
the input signal level equals the output signal level.
Frequency Response: 80Hz to 10kHz +/-
3dB
Gain (into 8 Ohm load): +8dB maximum
The V-1094A is capable of driving 150 Valcom
one-way speaker/amplifier assemblies.
INSTALLATION
