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 in-
puts 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 de-
vices 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 qual-
ity 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.
