TB-SD & TB-SR Station Master Talkback Intercom Overview
These units are used for interfacing with the Sonifex Station Master studio switcher and are
similar to the 6 way talkback intercoms, except that the talkback routing and switching (DC
signalling) is handled by the Station Master.
All of the features regarding level control, use of the microphone, speaker, headphones,
volume control and external inputs are the same as for the TB-6D and TB-6R intercoms.
However, the TB-SD and TB-SR can be used to communicate with up to 4 other locations
(including the Station Master), or all of the locations by pressing the “ALL” button.
Whereas the TB-6D and TB-6R have talkback outputs and input on a 15-way male ‘D’ type
plug, the TB-SD and TB-SR have instead a remotes socket consisting of a 25-way female ‘D’
type. This contains switch and indicator controls for the 4 talkback buttons together with
power and talkback input/output/control lines to and from the Station Master.
Example Application For TB-SD & TB-SR
Using the Station Master as the core of a complete studio air-switching, distribution and
talkback system, up to 4 studios can be connected using the TB-SD and TB-SR. A typical
application would be to distribute talkback and audio feeds around a small radio station, as
in this diagram.
