At Audioarts, value engineering is straightforward:
– Define the features our customers require.
– Design cleanly with an eye toward quality and durability.
– Manufacture in an efficient manner, utilizing the best of
computer and machine technology.
With the Audioarts AIR-4 radio console we’ve brought
together what is essential for a compact radio console and
made it work the way it should. Ideal for smaller stations
looking to upgrade as well as larger facilities in need
of an auxiliary studio or newsroom console, the AIR-4
demonstrates a basic Audioarts design premise: Low cost
doesn’t have to mean low quality.
THE FEATURES YOU NEED:
The AIR-4 has four built-in microphone preamps, allowing
the use of a host microphone and three guest microphones
without the need for external mic preamps. The AIR-4 has
2
12 input channels, each with A/B source select, plus a 13th
fader for call-ins. External machine control, two program
busses, cue (with built-in speaker), talkback, mix-minus, and
CR, headphone and studio monitor control are all included.
Patchable USB connectivity for PC news, production work
stations or streaming audio makes the Audioarts AIR-4
perfect for local radio stations and internet broadcasters.
The AIR-4 draws upon Wheatstone Corporation’s extensive
investment in the latest design, tooling, and manufacturing
infrastructure. We design and manufacture our audio
consoles right here in New Bern NC, USA, to ensure our
reputation for quality, performance, and reliability remains
uncompromised.
The Audioarts AIR-4 mixing console delivers top broadcast
audio quality and an excellent feature set at a great price.
•1
2 stereo input fader channels, each with A and B
inputs and remote START logic
• Headphone output with built-in amplifier and
concealed jack
• 13th phone caller fader with talkback and auto
mix-minus to caller
• Dual meters: PGM 1 and Switched
(PGM 2 or external)
• Four high performance mic preamps with variable
gain trims to precisely match your microphones;
preamp outputs jumper to any input fader’s A or
B input
• LED switch illumination
• Two program busses with balanced outputs
(switchable stereo or mono mode)
• Additional external input feeds the monitor
section (for live air or pre-delay air monitoring)
• Control Room monitor switchable PGM 1, PGM 2
or external; can mute when CR mic is live
• Split cue — when any fader is in CUE, sends cue
audio to left channel and L+R sum of selected
source to right channel of monitor output
(switchable separately for CR and headphone)
• Tabletop mount, no cutout
• RJ-45 connectors for low cost wiring
• External power supply
• Front panel ON-AIR LED indicator, plus a closure
output to drive an external On-Air light relay.
• Studio output with independent source selection
and CR-to-studio talkback button
• Plug in faders and conductive plastic monitor
pots for easy replacement
• USB connection is patchable to any of your input
faders and internally dipswitchable to pick up
PGM 1 or PGM 2 output mixes. Lets the AIR-4
interface with your desktop computer for news,
music sweetening functions or to stream audio
mixes to and from the console.
• Built-in cue speaker; cue output can automatically
interrupt your main stereo monitors

Modern interface for modern studios
CONSOLE LOGIC DIPSWITCHES:
SW1 - CUE TO CR - routes the cue signal to
the main control room speakers for full range
sound.
TRIM POTS:
VU METER TRIMS - separate gain
trims for precise calibration of the
main program and switched VU
meters to your facility’s standards.
SW2 - CR SPLIT CUE - sends the cue signal to
the left CR speaker and a L+R mono summed
program signal to the right CR speaker (an
internal jumper can cause the same action in
the headphone circuitry).
CALLER GAIN TRIM to accurately
match the signal level required by
your caller interface device.
SW3 - STUDIO DIM - reduces the studio monitor
signal feed level when the studio TB button is
pressed.
PROGRAM GAIN TRIMS provide
optimal gain adjustability.
MIC GAIN - these four trimmers
optimally adjust the built-in mic
preamplifiers to your microphones.
SW4 & SW5 - when activated change Program 1
stereo output to mono (for AM stations).
SW6 & SW7 - do the same for Program 2.
DC POWER IN:
Remote power supply
keeps hum and noise
away from the console.
PROGRAM OUTPUTS:
Separate electronically
balanced RJ45 connectors
for program 1 and program 2
output mixes.
CALLER PORTS:
Separate electronically
balanced RJ45 input and
output connectors link to
your telephone interface
device.
4
MIC 1 – 4 INPUTS:
(electronically balanced)
Plug-in screw terminal
connectors accept low
level microphone signals
and input them to the
console’s four microphone
preamplifier circuits.
USB PORT:
Lets the AIR-4
interface with your
desktop computer
for news, music
sweetening functions
or to stream audio
mixes to and from
the console.
USB ANALOG OUT:
May be patched to any of
the console’s 24 stereo RJ45
inputs, or looped to outboard
processing gear. Internally
dipswitchable to pick up
Program 1 or Program 2
output mixes.
MIC 1 – 4 OUTPUTS:
The outputs of the AIR-4’s low
noise mic preamplifiers can be
patched directly to any of the
console’s 13 fader channels or
be looped through outboard
processing gear.
Interfacing AIR-4
The AIR-4 is the most flexible analog mixer in its class. Its rear panel is laid out in a
straight-forward and intuitive manner that makes interfacing it a snap. Once wired, a
rear-panel cover protects your work and streamlines its appearance.

STUDIO OUTPUT:
Independent studio output normally wires to your
studio monitor speaker amplifier.
EXTERNAL IN:
A balanced external input to feed either the control
room or studio monitor sections. It is generally wired
to an off-air signal source.
CR OUTPUT:
Feeds CR monitor speaker
amplifier so the operator
can listen to PGM 1, PGM 2
or EXT IN, or even the CUE
feed if dipswitch selected.
DB-25 LOGIC CONNECTOR:
Provides logic ports for all 13 of your fader machine starts,
on-air tally relay port, guest TB to CR logic function, as well as
a cue output for an optional external cue amplifier.
CR MUTE/TALLY:
13 dipswitches, one for each
console fader. When activated
cause the CR speakers to
mute (preventing open mic
feedback) and send an on-air
tally signal to activate an
external On-Air light relay.
INPUTS:
24 stereo balanced RJ45 inputs provide A
and B sources for the twelve fader channels.
Mic preamps jumpered to these inputs will
automatically feed both left and right inputs
when an RJ patch cord is inserted. (Note the
13th phone module fader is a mono channel,
but can also receive a mic preamplifier signal.)
