INTRODUCTION
The Master Unit
The Master unit distributes Audio and control data to the
respective Slave units connected.
System Controller, Master or Slave
To set up a Master unit to be either System Controller or
Master/Slave the LINK switch on the rear panel must be
set up correctly.
Out:
The monitor operates as a System Controller
In:
The monitor operates as either:
- a regular Master with digital Inputs (analog Inputs are
only with the optional analog I/O card installed) or
- as a Slave unit.
I/O
The Master unit contains AES/EBU Input connectors and
three Link connectors carrying both audio and control data
to connected Slave units.
Connectors
1* AES/EBU - XLR
2* Link RJ45 connectors
1* Link/Input RJ45 connector
1* Word Clock BNC sync
Option slot
Two card types are currently available.
• An analog Input module giving the option of feeding a
Master unit with 2 analog Input signals.
• An AES Digital Input card giving the option of sending all
six channels in a 5.1 setup to one single Master monitor.
From there the signal is distributed to 4 slave monitors
and Sub via the TC LINK RJ-45 connections creating a
fully digital 5.1 setup.
The Slave & Sub Units
The Slave and Sub units contain one RJ45 Input connector
and one Link connector. Via the RJ45 Input connector the
Slave unit is supplied with audio and control data from the
Master unit. Via the RJ45 Link connector transmission to
additional monitors is possible.
Initializing Network
When the setup is powered up for the first time, the Master
unit scans the setup in order to determine the number of
monitors connected. Each monitor is recognized via a
unique serial number but can be renamed according to task.
After the initial scanning of the set-up, the Master unit will
be re-scanning the setup every 5 seconds in order to
determine any change.
Additional AIR Control units
Any additional control units, such as the optional AIR Soft
Remote or the AIR Remote, can be connected to any free
"Link" connector in the system. (see below)
Control data is transmitted via the System Controller, and
distributed to other monitors in the network.
Remote Control
AIR monitor systems can be set up and controlled locally
via the Master monitor’s user-interface via the optional
remote control or from a PC/Mac.
AIR SOFT - Software Remote
Any parameter in the System Controller including the setup
parameters can be controlled via the “AIR SOFT”.
Additionally, software upgrades and installation of such can
be done via AIR SOFT.
Hardware Remote
A simple remote level control, controlling the level of the
entire set-up. Control data is transmitted to the Master unit,
and distributed from there ensuring that any monitor
hooked up, is set identically.
Air PC/IP
An optional software dedicated for the Advanced Installer.
In addition to the common parameters the PC/IP software
offers Parametric EQ and various Parameter Lock
functions.
Common Features
- for both the Master and Slave units
Advanced Condition Monitoring
For both the Master and the Slave units several protection
systems are included in the AIR monitors. This is to insure
both short term protection against large dynamic pulse
signals, but also to insure long term protection against
over-heating and thus permanent damaging the drivers.
Long term thermal protection
Inside the amplifier module the temperature of the heat
sink is constantly monitored so any dangerous over-
temperature situations can be avoided - this is for
protection of the entire electronic module. Furthermore the
temperature of the tweeter voicecoil is calculated with
behavioral modeling of the tweeters thermal characteristics.
Beware
Power down procedure:
• In general, use the "sleep function" (Press and hold Exit
on System controller),
• System will automatically go into sleep mode after
2.5 hours.
• If you need to switch the system off on the mains switch
on rear panel, please make sure to turn down the global
volume and switch Slave monitors off before Master
monitors.
