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
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
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
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
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
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.
