TELCO INPUT/OUTPUT MODULE
The optional Telco Input/Output module interfaces a telephone hybrid with the console. The module also
provides a host/caller recorder connection. One or two Telco modules may be installed.

Level Meters
The electronic meter movements have no individual meter calibrations or alignments. The meters use IEEE
standard 152-1991 (standard audio program level measurement). When set for PPM display mode, via the
Output module DIP switch, the PPM indications will light and a +4 dBu sine wave output signal will display at
-8 on the PPM scale. When set for displaying VU, the VU indications will light and a +4 dBu sine wave output will
display at 0 on the VU scale. Each of these settings corresponds to -20 dBFS (decibels below Full Scale digital
output).
The meters display the left channel audio output on the top row and the right channel audio on the bottom row
of each meter. The right hand meter can momentarily show the Cue bus level by pressing the Cue button on the
Output module. While this button is pressed the top row of LEDs show the Cue bus output level.
The Cue/Talkback speaker’s impedance is 45 ohms with a 3-watt power-handling capacity. The speaker volume is controlled by the Cue volume control on the Monitor module. A 3-watt amplifier IC on the Monitor
module drives the speaker. Refer to Chapter 5, Maintenance & Alignment, Meter Panel Assembly for speaker replacement procedures.

plete discussion of the Power Supply refer to the
AirWave Universal Power Supply Technical Manual
(PR&E # 75-41).
The AirWave Universal Power Supply (AUPS)
consists of a power transformer, selectable for 115
VAC or 230 VAC operation, chassis-mounted rectifiers and filter capacitors and a regulator circuit
board mounted to a heat sink.
The power supply is protected by a replaceable
AC mains fuse located in the power entry module,
thermal circuit breakers (auto-reset type) within
the transformer primary, internal fuses on the
transformer’s critical secondary outputs and selfprotected current-limiting regulators.
The power transformer has four secondary windings. Three are wired to bridge rectifiers and filter
caps mounted on the chassis floor, while the fourth
is connected to a bridge rectifier (CR6) and filter
cap on the regulator circuit card. All voltage regulators fasten to the heat sinks.
The power supply has five output voltages:
• +5 volts @ 6.5 A for the console’s logic circuitry
• +12 volts @ 4.0 A for the clock/timer
• ±16 volts @ 1.0 A each for the audio circuitry
• +45 volts phantom @ 0.100 A for condenser
microphones.
The +5 volt (U2) and +12 volt (U1) regulator
