Triple Line Input Stereo Module
ON
The channel on/off switch operates in tandem with the fader.
There are two methods of activating the channel:
A. Press the `ON' switch (Green LED is on). Then by moving up the fader, the signal is sent to
the master and at the same time a mic-on/channel on indication is sent to the remote
connector.
B. When the 'ON' switch is 'OFF', no LED is illuminated. As the fader is moved upwards, the
channel is put into 'stand-by'.
At this point there is no "mic-on/channel on" signaling or audio to the master. Pressing the 'ON'
switch activates the channel and the green LED is on.
In order to switch the channel and mic-on signaling off, the 'ON' switch should be deactivated, or the
fader closed.
Fader
The fader is an ultra smooth 100mm model controlling the internal high quality VCA's and sending on/off
information to the logic circuitry. There is no audio going through the faders, which guarantees noise free
fading forever! When the fader is closed, the signal is automatically muted, providing a cut-off in excess of
100 dB. This high dB cut-off value ensures that the main output is protected from cross talk from
announcers.
Digital Otput:
The AirLab Triple digital input have 2 digital outputs. AES3 on the XLR and S/P-dif on de black cinch.
Dependent on the jumper setting the output is giving the stereo PROG signal or the stereo SUB-signal.
Normal the output level is -9dBFS but the level (headrome) can be adjusted.
The digital output clock depend on the digital input clock of the selected digital input (Line-A switch).
If no digital input signal is connected or selected (Line-A LED well be RED-flashing) the output-clock
well be 44.1kHz.
Is a digital input signal is connected and selected (Line-A LED well be GREAN or of) the output clock
well be equal the input-clock.
