Clear-com CS-702 Two Channel Headset Main Station
Clear-com CS-702 is a 2-channel compact main
station that can monitor intercom activity on
one or both channels with
individual Listen Level controls. Monitoring intercom activity is
possible through a headset, or external earphone or speaker. The CS-702
supports up to
55 beltpacks or 7 speaker stations.
Talk Selection
The CS-702 contains a mic preamp with limiter and
proprietary speech-shaping circuits. An individual electronic
momentary/latching Talk button is provided for each channel and light dimly
when latched.
Call Signaling
The CS-702 provides individual Call buttons for
each channel to signal all stations on the
channel(s). When a remote
station operator sends a Call signal, the CS-702’s associated
Talk button
lights brightly, attracting the attention of an operator who have removed
their
headsets or turned off their speakers. Individual sidetone can be
adjusted for each channel.
Remote Mic Kill (RMK)
Pressing the Remote Mic Kill button will turn off
the microphone talk circuits of all beltpacks, eliminating noise from the
open headset microphones.
Program Input
The CS-702 has a balanced, mic or line-level
program signal for monitoring in the headset
and/or mixing the intercom
audio on one or both channels. The front panel provides a local
Program
Monitor volume control and individual Program Send level controls. It also
provides a Program Send on/off/interrupt switch for each channel. When
interrupt is
selected, program is interrupted when the Talk button is
pressed.
Power Supply and Supply System Protection
The CS-702 provides visual indication of power
supply conditions. In the event of a short
circuit or current overload,
the CS-702’s electronic overload protection circuit will shut down
the
output to avoid damage. As soon as the fault condition is removed, the
auto-reset circuitry
will automatically restore system power, even under
full-load conditions. There is no need to
disconnect stations to allow
the power supply to reset.
