The MS-702 is a one-rack-space, two-channel main station with a
regulated 1.2-amp “fail-safe” power supply, individual channel short-circuit
protection, and a versatile intercom monitoring system. It supports two
intercom channels with up to 40 beltpacks or 10 speaker stations. It features
Clear-Com’s excellent speech intelligibility in both high- and low-noise
environments.
Monitoring System
The MS-702 can monitor intercom activity on one or both channels with
individual listen-level controls. Monitoring intercom activity is possible
through a headset or the internal loudspeaker. The high-sensitivity internal
speaker provides intelligible communication in the typical active production
environment.
Talk Selection
The MS-702 contains mic preamps with limiters, and speech-shaping
circuits for enhanced intelligibility. An individual electronic momentary/
latching talk button is provided for each channel. These buttons light
dimly when latched - blue-color LED while in stand-by and amber-color LED
when latched. The channels may be accessed separately or simultaneously
without tying them together. An optional gooseneck mic is available.
Announce Output
For paging applications, the MS-702 provides a balanced, line-level
output signal to a
1
/4-inch TRS connector on the rear panel. The front
panel “Announce” button activates the output and the Announce relay.
The relay circuit, on a separate
1
/4-inch TRS connector, is typically used to
mute control-room monitors during live announcements.
Visual And Audible Signaling
Visual “call” signaling attracts the attention of operators who have removed
their h
eadsets or turned o their speakers. Call buttons for each channel
signal all stations on that party line by ashing brightly. Along with the visual
signal, the station’s speaker will emit an audible signal if the remote station
operator holds the Call button for more than 2 seconds.
Remote Mic Kill (RMK)
The MS-702 is equipped with a global RMK button. It will turn o the micro-
phone talk circuits of all Clear-Com beltpacks in the system, eliminating
extraneous noise from the “open” headset microphones.
Program Input
The MS-702 accepts a line-level external program input for monitoring in the
headset and speaker, and/or mixing with intercom audio on either or both
channels. When Interrupt is selected, the program signal is interrupted when
the Talk button is pressed.

Power Supply & System Protection
The MS-702 provides visual indication of power
supply conditions. In the event of a short circuit
or current overload on a channel, that channel
will shut down while the other one continues
to operate. As soon as the fault condition is
removed, the “auto-reset” circuitry will restore
power to that channel - even under full load
conditions.
Simple Set-Up
The MS-702 connects to remote stations with
standard, two-conductor shielded mic cable.
User-selectable setup dip switches are provided
on the rear panel.
