Telco Module
PAN
The PAN enables positioning of the incoming caller signal. The range is not restricted in
order to enable to position any incoming signal anywhere in the stereo image.
CUE/SELECT/RING
Automatic pre-fade listening/post pan, or cue, allows a caller to be heard without being in
the broadcast. When activating the cue switch, the caller is connected to the CUE bus and
listens to the talk back MIC of the engineer (fader closed).
The CUE switch shows an incoming call by a flashing CUE LED. Hitting the CUE switch
makes a connection as described above. A remote switch can pick up a call by wiring the
remote connector of the Telco module.
The 'ON' switch works in conjunction with the fader switch.
If the green LED is on, the channel is 'active'.
There are two methods of activating an incoming call:
A.
will illuminate and the caller is connected to the Telco module but not yet heard in the
broadcast because the fader is still down.
By opening the fader, the Telco module will be activated and the signal will enter the
program. When the fader is closed again the program signal will be muted, when the
fader is at its lowest position.
B.
now opened. In this situation, none of the signals are active but as soon as the ON
switch is activated (with a flashing CUE/RING switch) the caller will be "On-AIR".
All switching is carried out electronically and free of noise for years to come.
If the CUE function is active, it will be disabled when the channel is activated.
NOTE: In the Telco module it is not possible to "Cue" when the channel is up and
FADER
The Airlab is fitted with a modern ultra-smooth linear fader controlling a high quality VCA
and the Airlab internal logic circuitry. This system eliminates any noise from disturbing the
audio signal path. When the fader is closed, the signal will be automatically muted, which
provides excellent fader attenuation in excess of 100dB.
