The AIRLAB has the possibility
to be loaded with up to 16 Telco modules.
Due to an ingenious Mix-Minus
system alignment is only necessary during installation.
The AIRLAB Telco module
is a straight forward design making communication very easy.
The first control is the
front panel accessible, trimmer for side tone adjustment,
only necessary during installation.
The Telco Send knob controls
the outgoing signal to the caller. This signal is derived
from the PROGRAM or SUB bus.
The line input can be switched
to a balanced XLR input connector to accept an external (digital)
hybrid instead of its own internal hybrid.
A separate input gain control
with HP and LP filters be used to enhance intelligibility.
The SUB and PROGRAM assign
switch routes the signal to both outputs if needed.
The stereo Aux. control
has jumpers that select its source to be pre or post VCA/MUTE.
A Pan-pot and CUE/Select
switch plus the ON switch completes the Telco module.
A 100mm linear fader controls
a high quality THAT VCA, eliminating any fader wear out in
Connecting a Caller can
be accomplished with the ON switch when the fader is up or
with the CUE/SELECT/RING switch when the fader is down.
When CUE is active in the
TELCO module, the caller is connected to the CUE bus and
also the engineers talk-back, but does not go ON-AIR yet
as the fader is down.
It is possible to connect
both the Cue and On switch to a remote unit, allowing a director
to control the broadcast.
A "Connect" LED
positioned below the High Cut switch indicates that the internal
Hybrid is active.
CENTRALIZED MASTER SECTION
WITH PROGRAMMABLE UTILITIES AND SCRIPT SPACE.
The master module is divided
in three sections. The first "module" houses the
TAPE SEND which selects the feed to the tape output.
This could be either the
SUB output signal or the AUX. output signal..
The stereo Aux. master controls
the outgoing Aux. signals from the input modules. A Talk-back
to AUX. switch is provided for.
The lower part of this "module" houses
the Control Room Monitor section that can be fed by an EXT(ernal)
stereo input, the stereo Aux output, a stereo On-Air signal
or the stereo SUB output signal. All selections have LED
indicators and the lowest positioned switch has priority
over the input selectors positioned directly above.
The CUE balance pot adjusts
the balance between the PROGRAM output or another selected
input source and the CUE signal (when selected).
A cue LED indicates when
a CUE signal is on the CRM or Phones.
Separate Phones and CRM
controls, with a DJ mic on mute indicator on the CRM, complete
