AIRCOM Manual
5.6.
Monitoring
Commentator A and B only, GUEST has no monitoring facilities.
Each monitoring section provides 6 audio sources with individual level controls and a phones level
control as a master.
4 sources are external: Program and Intercom inputs.
2 are internal: Local commentators A and B.
5.6.1.
Internal Sources
SIDECHAIN: The commentator’s own microphone signal pre limiter, i.e. channel A for commentator A
and channel B for commentator B. The signal is present only, when a commentator is „active“ an output,
i.e. if ON AIR button is active or a TALK button is depressed *.
CO-COMM: The co-commentator’s microphone signal pre limiter, i.e. channel B for commentator A and
channel A for commentator B. The signal is present only, if the co-commentator is ON AIR or holds the
CO-COMM intercom button depressed **.
* different behaviour if CONFERENCE is activated (refer to 5.6.5) or if SIDECHAIN PRE is on by
configuration (refer to 6.8)
* different behaviour if CONFERENCE is activated (refer to 5.6.5)
5.6.2.
External Sources
PROGRAM: Program signal, fed into 3pole XLR labelled PROGRAM on rear panel.
COM 1: Intercom signal, fed into 3pole XLR labelled COM1 on rear panel.
COM 2: Intercom signal, fed into 3pole XLR labelled COM2 on rear panel.
COM 3: Intercom signal, fed into 3pole XLR labelled COM3 on rear panel.
5.6.3.
Intercom Call Signalisation
Incoming audio signals at COM1, COM2 and COM3 are signalised at the respective TALK buttons 1, 2
and 3. Signalisation appears at commentator A and commentator B at the same time *.
* different behaviour by configuration refer to 6.5 und 6.7
A TALK button lights up yellow, when the incoming signal level is higher than approx. -20dB.
Signalisation is stored for approx. 8 seconds, so that even a short signal is clearly indicated.
When a TALK button is depressed, signalisation will go off immediately.
When a TALK button is depressed while there is an incoming signal triggering the signalisation, the TALK
button lights up orange. In this case signalisation is not stored, thus the orange colour follows the
incoming modulation.
Basically the CO-COMM buttons provide the same signalling function, but they do not depend on audio
modulation. They are triggered when the co-commentator presses his CO-COMM button. The
signalisation is not stored, it is only active as long as the co-commentator holds his CO-COMM button
depressed.
