6.1 COMMUNICATION WITH TELCO MODULE
ENGINEER TO/FROM TELCO
Communication with the engineer is easily accomplished by activating the CUE switch in the Telco module.
An open communication is achieved now between caller and engineer.
ANNOUNCER TO/FROM TELCO
The CUE switch on the Telco module has to be activated. The moment the Announcer hits his cough
switch communication takes place between announcer and caller (Telco module).
There are several software programmable functions available here. In chapter 14 you can find detailed
information about the programmable options of the Airlab.
ALIGNMENT OF THE CHANNEL
With the fader closed (or muted channel) the CUE switch will be activated; the CUE to CRM function in the
master section must be activated. The gain control is used to adjust the level of the incoming signal until a
0 dB reading is achieved. If the 'ON' switch is now activated, the signal level will be nominal. When the
fader is opened, the CUE signal will be automatically reset (turned off), and its associated LED will be
switched off.
The CUE signal can be heard in two ways:
1. Through the stereo Control Room Monitors by activating the CUE to CRM function in the master
section. If the CUE is activated in one of the channels, the CRM and meters will be activated
without interruption of the main output.
2. By way of an externally connected CUE amplifier with loudspeaker.
