Input module 5-6 is identical to triple input module 1 to 4 except for the line-B input that has
been transformed to a USB in and output.
GAIN
With the gain, the source level is adjusted to the internal mixer level.
This is for both Mic/Line inputs as well as the USB input.
LINE - USB
The stereo line input is a high impedance input for connecting play-out systems and or CD
players.
The USB position of this switch changes this module into a USB in and out module.
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.
The controls of the input modules have the following functions.
A small green led lights when data is send over the USB cable.
MIC
The Mic input is a professional balanced input circuit with 48volt phantom powering for
condenser mikes , this means that you now have a studio-class microphone-channel at your
disposal. A microphone is an instrument that turns acoustical signals in electrical ones,
without any amplification (in most cases).
These very small signals have to be amplified without any noise and interference from the
mixing table.
The AIRMATE-USB is equipped for this purpose.
Instead of one sensitive connection at the input channel, the AIRMATE-USB has 2 connections
per channel (balanced).
It is now possible to connect the
2 wires in your microphone cable to the balanced input
as follows:
- One wire to pin 2 of the XLR connector.
- The other wire to pin 3 of the XLR connector.
- The shielding on the remaining pin 1 of the connector.
What are the advantages of this system?
A microphone cable connected in this way is completely
insensitive for outside interference.
EQUALIZER
The module has a three band equalizer to control the high, mid and low frequencies
individually on carefully chosen frequencies.
AUX SEND
Below the Equalizer there is the stereo Aux send that can be set to send stereo source signals pre or post
fader by jumper settings. The factory default is post fader.
CUE
Below the equalizer you see the stereo CUE switch (Pre Fader Listening), this switch gives you the possibility
to check the signal before you mix it with your other signals .
ON
The ON switch is used to activate the module and it generates a signal that can start turntables and CD
players as well as jingle machines. This switch send out a momentary pulse or switches continuously inside
the Start connector on the back of the console.
