TELCO MODULE.

The AIRLAB MK2 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 MK2 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 the future.
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.
