The AIR concept

The master/
slave concept
The networking feature allows all monitors in a setup –
no matter if it is stereo or surround, digital or analog – to
always be aligned. This provides great possibilities in
terms of general control of the entire system.
Two physically different units exist for each AIR model:
a
Master unit and a Slave unit .
AIR Master units
An AIR Master unit is able to:
►
receive digital audio on AES connections
►
receive analog audio (if an analog card is installed)
►
send and receive audio and control data via the
proprietary TC LINK connection.
Fig. 1: AIR Master monitor – rear
Audio signals from your studio are fed to the Master
monitors only, and the signals are distributed from here
to the connected Slave units through a proprietary net-
working protocol.
Please note that a Master monitor
acts exactly as a Slave monitor when its TC LINK
button is set to the in “IN” position.
Master monitor as System Controller
Setting up an AIR system is done from the System
Controller monitor.
You set up, set tasks and calibrate all connected mon-
itors in the entire system either using AIR control soft-
ware or from a Master monitor that acts as the System
Controller monitor.
One – and only one – of the Master monitors must be
set up as the System Controller. This is done by set-
ting the TC LINK button on the rear panel to the “Out”
position.
Air Slave units
A Slave unit is able to receive and distribute audio and
control data via the proprietary TC LINK connection.

The Master unit distributes audio and control data to the
connected Slave units.
System Controller, Master or Slave
To set up a Master unit to be either the System Control-
ler or a regular Master or Slave unit, the LINK switch on
the rear panel must be set up correctly.
