1. INTRODUCTION
The AIRMATE-USB has THree types of Modules.
Triple Input Modules (positions 1-4) have the following features
• Professional low noise balanced Mic pre-amp with 48 volt phantom
powering.
• Two pairs of line inputs with optional R.I.A.A. equalized pre-amp on
line-B for turntables.
• Gain control
• Three band stereo equalizer
• Start (ON) switch
• Stereo CUE switch for pre fade listening
• 100mm smooth professional faders
Input modules 5 & 6 are identical to triple input modules 1 thru 4
except for the line-B inputs have been converted into digital USB input
and output to allow easy interface with PC’s (Windows & Macintosh
computers). This feature will allow you to connect to the Internet via
your computer for “Live” streaming of audio to the Internet.
Input modules 7 & 8 have a high quality built-in Telephone Hybrid in
each module which are switch-able to stereo line inputs when only one
or no Telephone Hybrid is needed in your live broadcast studio.
2. TRIPLE INPUT MODULES 1-4
The input modules switches & controls have the following functions:
Each of Modules 1 thru 4 has three selectable inputs. The three types
of inputs consist of a Mic input and two pairs of stereo line inputs. In
the Mic switch position, the module is a normal mono module. When
the Mic is switched out, you have the choice of Line A or B stereo inputs which allows for the module to become a stereo module with both
left & right signals to feed the stereo mix buss.
GAIN
With the gain control, the source input level can be adjusted to the
required internal mixer level. This control adjusts both the Mic input
and the two pairs of line inputs with the same control depending on the
switch positions. Mic gain can be increased by 20dB by internal jumper
settings (if needed).
STEREO LINE (A B)
The stereo line inputs (A or B) pairs are high impedance inputs for connecting the stereo line level outputs of devices such as CD players.
MIC
The Mic input has a balanced XLR input connector with 48volt phantom powering for condenser mikes. The Mic-pre
circuitry uses the latest technology studio-class components. The low-noise design and excellent phase spec that
D&R is known for is integrated throughout the AIRMATE-USB.
Using balanced microphones & cables allows for the quietest and high quality audio signals throughout your Airmate-USB mixer. You can use standard
balanced Mic cables available at any pro audio dealer or music store.
The Airmate uses chassis-mount female XLR type Mic input connectors. Any
standard pro audio Mic cable will have the mating male XLR connector.
EQUALIZER
Each module has a stereo three band equalizer to control the high, mid, and low frequencies individually. The D&R
designers used carefully chosen frequencies in the equalizer circuitry to enhance the Mic input as well as the stereo A & B line inputs.
AUX SEND
The next control is a stereo Aux send that sends stereo source signals to the stereo Aux send buss Master and
then to the output connectors on the Master back panel. The stereo Aux send is for external effects such as re-
verb, echo, or headphone ampliers. Each Aux send can be set pre or post fader by changing jumper settings on
the circuit board of each module. The factory default is post fader.
CUE
Below the AUX SEND is the stereo CUE switch (Pre Fade Listening), this switch allows you to check the signal before you raise your channel fader up and mix it with other signals in the mixer.
ON
The ON switch is used to activate the module and generate a start signal for turntables, CD players, and jingle or
cart machines. This switch sends out a momentary pulse or shortens continuously two pins of the Start connector
on the back panel of the console.
FADER
Final control is the high quality, 100mm long throw K-Alps stereo channel fader with integrated fader start switch.
At the beginning of the fader movement you will feel integrated start switch that is activated when you bring up
the fader. This switch activates the start circuitry that is connected to the Start Connector on the module back
panel as described above. A Red light is activated if the SELF OP switch in the master section is activated. Control
Room monitoring will be muted when a Mic is opened (DJ setting).
INPUT CONNECTORS
On the back of modules 1 thru 4, you nd seven connectors for each module.
The Mic input is a balanced female XLR type
connector. The two pairs of stereo line inputs use
Cinch pro RCA female type connectors. If you use
turn tables and need phono type R.I.A.A. equalized pre-amps, D&R offers an optional plug-in
R.I.A.A. pre-amp for Line inputs B at a nominal
price. The level can be set with the gain control to
match any available phono cartridge.
Both Line inputs A & B are identical with the exception of the optional phono pre-amp. Being unbalanced, the shield and (-) or common need to
be connected together during installation.
In order to use the START switch, it requires
two pins in the ¼” stereo connector located on
the back panel to be wired. The tip and ring are
shorted when the ON switch or fader switch is
activated. Once you have done this, you can start
a turntable with the ON switch (if the START connector is wired on the back panel).
*NEVER CONNECT AC POWER VOLTAGE TO THIS REMOTE-JACK*
The START switches quick start turntables through the remote jack via a shorted contact action in the ¼” stereo
connector on the back of the mixer. If your turntable only needs a pulse to start, ask your dealer to modify the internal circuitry to change it into a momentary action, so it can be used as a pulse start switch.
Connections on the START connector can only be made with a maximum of 24 Volts 50 mA. Please
contact your dealer if you are uncertain.
*NEVER CONNECT AC POWER VOLTAGE TO THIS REMOTE-JACK*
INSERT
This ring/tip/sleeve stereo jack socket let’s you insert signal processors such as compressors/gates or special voice
processing units to “improve” your voice to be the ultimate announcer/DJ sound.
The Ring of the stereo jack sends the channel signal and the Tip accepts the return signal.
Below you see the type of cable you need.
If you are going to make a cable yourselves, do it like this.
Connect the tip from the stereo cable to the tip of one of the mono jacks and the ring of the stereo cable to the tip
of the other mono jack.
Now insert the stereo jack into the Airmate’s insert and connect the mono jack that produces a hum when the tip
is touched by your nger (and the related channel fader is open) into the processors output.
The other mono jack should be inserted into the processors input.
In case your processor has XLR inputs connect the tip of the stereo jack to pin 2 of the Female XLR and short pin 1
and 3 with each other and connect to ground (sleeve)
This also goes for the other Male XLR, connect the ring of the stereo jack (which sends signals) to a male XLR
pin2. Short here pin 1 and 3 and ty to ground (sleeve). This has to be done because the insert is not balanced.
See below the cable you need.
SPECIAL OPTIONS FOR MODULES 1 - 4
Located on the input channel circuit boards are several jumpers that can be changed to enable different congurations of the channel settings. If changes are required, we advise you to contact your local dealer to have these
changes performed.
The following 7 jumper settings can be changed to adjust the Airmate-USB to your needs.

panel.
GAIN
With the gain control, the source level is adjusted to the required internal mixer level.
This is for both Mic/Line inputs as well as the USB inputs.
LINE - USB
The stereo line input is a high impedance input for connecting any stereo line level
device such as CD players, iPods, tape decks etc. The USB switch changes the module into a USB in and out module. The USB connector will communicate with playrecord devices such as computers using a DAW (Digital Audio Workstation), Windows
Media Player, and/or CD players using a USB output connector. It is an input that
can be connected to any standard USB connector on PC’s to make an easy interface
with music programs running on the PC. When the USB connection is made between
the Airmate-USB and your PC, your computer will recognizes the USB device as new
hardware. A small green led lights when data is sent over the USB cable.
In Windows Media Player, you can change settings to allow it to work as a player or
recorder.
The controls of the input modules have the following functions.
MIC
The Mic input is a professional balanced input circuit with 48volt phantom powering
for condenser mikes which delivers studio-class microphone quality to your announcer/DJ channel.
EQUALIZER
Each input module has a three band equalizer to control the high, mid, and low frequencies individually at carefully chosen frequencies.
AUX SEND
Below the Equalizer is the stereo Aux send control that can send mono Mic or stereo
source signals (pre or post fader via PCB jumper settings) to the stereo Aux Send
buss. The factory default is post fader.
CUE
Below the Aux send is the stereo CUE switch (Pre Fader Listening), this switch allows
you to check the signal before you mix it with the other signals in the Airmate-USB.
ON
The ON switch is used to make a connection that can start turntables and CD players as well as jingle or cart machines. This switch sends out a momentary pulse or
switches continuously inside the Start connector on the module back plate at the rear
of the mixer. See “Start switch” on page 4.
FADER
Final control of the channel is the 100mm long throw K-Alps stereo channel fader with integrated fader start
switch. The channel fader sends the amount of signal from the associated channel to the master mix buss. At the
beginning of the fader movement you will feel an internally built in start switch that is activated when you bring up
the fader. This switch activates the start circuitry and controls externally connected devices such as CD players etc
(via the Start connector on the back).
INPUT CONNECTORS
On the back of your AIRMATE-USB modules 5 and 6 you will nd the following ve connectors.
Two unbalanced line input RCA Cinch connectors (stereo input) for connecting CD
players or any play-back devices such as cart machines, cassette players, or iPods. Any
line level equipment can be connected here. The level can be set using the gain control to
match most source levels.
The left RCA Cinch connector is the left input and the right RCA Cinch connector is the
right input. The shield is to be connected to the ground or case of the RCA Cinch connector.
The USB connector is wired according to International standards and is a stereo USB1.1
Codec (HID Interface) digital input, as well as an output.
The START switch has two active connections to be wired. The tip and ring are shorted
when the ON switch or fader switch is activated. Once you have done this, you can start a
turntable or other devise with the ON switch via the START connector on the back panel.
The START switches quick start turntables through the remote jack by a continuous contact action at the back of the mixer. If your turntable only needs a pulse to start, ask your
dealer to modify the internal circuitry to change it to a momentary action, so it can be
used as a pulse start switch.
*NEVER CONNECT THE MAINS TO THIS REMOTE-JACK*
Connections on the START connector can only be made with a maximum of 24 Volts by 50
mA.
Please contact your dealer in case of doubt.
The balanced Mic input is on XLR and can provide 48volt phantom powering.
