remotely from the CCU) to the PROGRAM, TECH and STUDIO mixer circuits,
which are sent multiplexed digitally to the CCU.
The listening circuits permit each commentator to select the P.A., Guide, Aux,
IS and Program signals for his right earphone (and the right f' back local analog
signal, if present).
These can be mixed for listening if desired, and are accompanied by the
specific coordination sounds for each commentator (CC/FB TO COM), labeled
on the front panel as " Coord RX" .
The signals set LOCAL T' B (TECH)/CUE/RINGER can be addressed from the
CCU to any ear (right, left or both).
The studio feedback PGM FB is sent to the left earphone with the analog signal
left f' b if present.
When a commentator speaks to the local CCU technician, the signal remains
separated from the program. The same happens when a commentator speaks
to the studio. The push-buttons (PTT) intercom ' Push to Talk' send the
commentator' s voice to the corresponding circuits.
The " Channel On" switch allows the commentator' s signal to be sent to the
program circuit. This can be remotely activated.
The " STAND ALONE" switch allows to send the commentator signal to the
program circuit. This switch can be activated remotely.
In " STAND ALONE" mode the left earphone simply receives the signals at the
corresponding " analog feedback left" banana plugs, while right earphone
receives the mix of the signal at the " analog feedback right" banana plugs with
the local program mixed in the CU.
When the unit is in STAND ALONE mode the program sound is the mix of of
the CU channels without including the sound from other external sources.
When the CU works in STAND ALONE mode, there is neither CUE nor Local
Talkback and Ringer arrives to the left ear. The intercommunication with the
CCU (LOC T/B) and CUE or the studio feedback are sent to the left earphone.
