Figure 2-11: Typical Cable or School Television Studio Installation
The system has several 2-channel RM-702 rack mount stations and several wall
mount 2-channel stations. The system is powered from a Clear-Com power
supply that also provides the terminations for both channels.
A line of single-channel beltpacks is connected to channel A. The beltpacks are
used for the cameras and floor managers. Normal communication between all
parties is on channel A.
Channel B is connected to talent receivers for announcers. The program that is
to feed the announcers is connected to the first RM-702. Its DIP switch options
are set to insert program on channel B and interrupt the program when a call
signal is present on channel B. The option DIP switches for placing a call signal
on channel B is set on both RM-702s. Now, either RM-702 will interrupt the
program feed to the announcer when a talk is initiated from it to the announcers.
A PA amplifier is connected to the announce output of the first RM-702 such
that the operator of that station could talk directly to everyone in the studio.
