Thanks for joining the growing ranks of
broadcasters employing Harris Corporation prod-
ucts designed by Pacific Research & Engineering.
Harris Corporation supplies audio products and
systems to the world’s leading broadcast facilities.
Our mission is to provide the finest quality prod-
ucts, systems, documentation and after-sale sup-
port.We invite comments and suggestions for im-
provements to this documentation and to all of
our services.
AirWave Digital is a very sophisticated console
with an extensive range of features contained in a
compact design.To obtain maximum benefit from
the console’s capabilities, read the
Installation, Op-
eration and Equipment Description chapters prior to
product installation.
PRODUCT OVERVIEW
Each Airwave Digital mainframe ships standard
with one each of these modules:
• Microphone Preamp
• Monitor
• Output
• Timer Control
The modules are installed into their standard
positions in the mainframe along with the Input
modules ordered. Additional Mic Preamps, Ana-
log or Digital Remote Line Selectors, and up to
two Telco modules, or various accessory panels,
may also be installed per the order. If required,
blank panels are available to cover unused mod-
ule positions.
AirWave Digital’s motherboard and module area
is completely contained within a welded steel chas-
sis for strength and RFI immunity.The meter panel
is hinged at the rear, locking down over the upper
part of each module, covering the audio and logic
connectors and the Logic Settings switches. Be-
neath the meter panel, the chassis bottom is open
for easy cable access.
Module Descriptions
Microphone Preamplifier
Contains five preamplifiers with individual gain
controls under a security cover. Phantom power
(+45VDC) is selectable for each input.The pream-
plifier outputs are +4 dBu balanced for connec-
tion directly to an Input module or to outboard
mic processing equipment. One module is supplied
standard, but additional Mic Preamplifier mod-
ules can be installed into any RLS or input posi-
tion.
Input
Each Input module can be configured as an ana-
log module (with two balanced, stereo inputs), or
as a digital module (with two AES-3 inputs)
through a plug-in SIM (Single In-Line Module).
Each Input module features two input selection
(A or B), channel on/off control, fader level con-

trol (with the selectable global fader start feature),
Cue and Off-Line control and output selection to
three program buses. Faceplate channel trim con-
trols allow the analog version to accept input lev-
els from -10 dBu to +4 dBu.
The module’s inputs are electronically switched
through a faceplate A/B Input selector. Logic wir-
ing to/from external peripherals connects to a 24-
pin logic connector on the faceplate. Logic and
module function options for the A or the B input
are set through a ten-position faceplate DIP switch.
A second, optional interface connector is available
for separate logic control for the A and B inputs.
Telco Input/Output
Up to two optional Telco modules can be in-
stalled into the mainframe next to the monitor
module. These provide the audio and logic con-
nections for up to two telephone hybrids and two-
channel recorders.A faceplate trim control allows
the module to work with hybrid outputs from -10
dBu up to +4 dBu.
EachTelco module’s output (Feed to Caller) can
be set manually to any one or a combination of
the three program buses and the Off-Line mix
bus. The Autofeed function automatically
switches the Feed to Caller between the Off-Line
mix and the assigned bus with the highest prior-
ity when the Telco module is turned off and on
(for more information, see the Telco Operation
section) .
Monitor
A double-width module with the monitoring and
communication controls for a control room (C/R)
and separate studio or voice booth. Volume
controls for C/R and studio speaker volume, C/R
headphone and Cue are included with independent
source selection for each room (three external
inputs, Pgm-1, Pgm-2, Pgm-3 and Telco). The
module includes a C/R to studio talkback system
with built-in adjustable electret talkback mic. Both
C/R and studio warning outputs are provided.
Output
Contains the various analog stereo line output
amplifiers and the AES-3 digital outputs for the
Program-1 (Pgm-1), Program-2 (Pgm-2) and Pro-
gram-3 (Pgm-3) buses. A monaural analog out-
put of the Pgm-1, Pgm-2 or Pgm-3 bus (operator-
selected) is also provided. Each balanced analog
output uses a nominal level of +4 dBu. Each digi-
tal output is AES-3 compatible.
This module also has faceplate buttons for the
right-hand signal level meter selection, Program-
2 or Program-3, with momentary Cue bus level
metering. The module also has two DIP switches
for selecting if Fader Start is enabled and the me-
tering scale (VU or PPM).
Timer Control
Provides manual or automatic control over the
digital timer located in the meter panel. This
module also routes power to the clock/timer
assembly and provides an external reset for a
studio mounted timer. It also provides for a AA
battery backup voltage to hold the console’s logic
settings in case of momentary power outage.
Remote Line Selector (RLS)
Two line selectors are available: an analog RLS
and a digital RLS. Each is a 7x2 input selector.
The analog version uses balanced, line-level mono
or stereo signals.The digital version uses AES-3-
compatible digital signals. Two banks of seven
switches provide manual, exclusive source
selection, among the seven common external input
signals for the two outputs.
Power Supply
The separately packaged rack mount power
supply is fully regulated and protected by inter-

Revision B.1 • 7/04
HARRIS CORPORATION

nal fuses and electronic safeguards against exces-
sive current.
The power supply has five regulated output volt-
ages. Two outputs (±16 volts) power the analog
audio circuitry. A third (+5 volts) powers the DSP
and logic control circuitry.The remaining outputs
power the clock/timer assembly (+12 volts) and
supplies phantom powering (+45 volts) for con-
denser microphones connected to the Microphone
Preamplifier module.
SPECIFICATIONS
AirWave Digital’s specifications are significantly
more complete, and the related test conditions
more defined, than those usually shown for con-
soles in this class. Be sure to follow the test condi-
tions and measure in the units as stated.
The specifications are for a fully-loaded AirWave
Digital-20 mainframe.
Test Conditions:
Specifications are for the basic signal paths, per
channel, with 600 ohm loads connected to the
analog program outputs.
0 dBu corresponds to an amplitude of 0.775
volts RMS regardless of the circuit impedance.This
is equivalent to 0 dBm measured into a 600 ohm
circuit for convenient level measurement with
meters calibrated for 600 ohm circuits.
Noise specifications are based upon a 22 kHz
measurement bandwidth.The use of a meter with
30 kHz bandwidth will result in a noise measure-
ment increase of approximately 1.7 dB.
Total Harmonic Distortion (THD) is measured
at a +23.5 dBu output level using a swept signal
with a 22 kHz low pass filter.
