INPUT MODULES

Every module has three selectable inputs. There is a microphone input on XLR, and two stereo
line inputs on cinch connectors and a Start connector.
The mic input is a professional balanced
input circuit with 48volt phantom
powering for condenser mics , 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 is equipped for this purpose.
Instead of one sensitive connection at the
input channel, the Airmate has 2
connections per channel (balanced). This
is a major difference between the Airmate
and other mixers. 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.
