Talkback to another Studio
STEP 9- TALKBACK
The Talkback feature is designed so that a console can easily communicate with another studio. In the ARC-15 studio, the operator pushes the TALK button on
mic channels One or Two and speaks through his control room mic into the Monitor/cue system of the other studio. The second studio responds back to the
ARC-15 studio and the audio is heard through the CUE system.
INSTALLATION
The ARC-15 has a talkback audio output to be sent to the remote studio and an audio input to the Cue system (with logic) to receive audio from the remote
studio. All connections are made to the 15 pin, D-sub LOGIC connector on the rear of the console. On site installation requires the building of a custom cable to
link the console to the studio at the other end.
a) TALKBACK INPUT-
b) INPUT LOGIC-
c) TALKBACK OUTPUT-
d) OUTPUT LOGIC-
OTHER CONSOLES
Talkback can be accomplished between non ARC-15 series consoles and studios. Care should be taken to assure compatibility between logic voltages.
GROUND LOOPS AND HUM
Because of long cable lengths between studios, it is possible for the talkback system to introduce hum into one or both studios. Isolation transformers may
be required on the analog inputs and outputs.
FACTORY CABLE
Arrakis has an optional cables available in various lengths from the factory.
TEST
Test talkback between the two studios. It is important to also listen for hum or noise in the Program output on the control room monitor speakers.
