channel, turn up the appropriate control. To not listen to a channel, turn
the control completely off.
4. Sidetone Controls: Each channel has a sidetone null control. This control
is used to set the amount of the microphone that is heard in the earphone
from that channel.
This control is a true hybrid null control and therefore is sensitive to
changes in line loading. For headphone use it is best to find the null for a
given channel and then rotate the control clockwise to obtain the desired
sidetone level.
If an external speaker is used providing a possible acoustic feedback path,
it will be necessary to use an almost complete null of the sidetone control.
5. Remote Mic Kill Buttons: It sometimes becomes desirable in an
intercom system to turn off all open microphones in a system.
Pressing and holding the RMK button for several seconds will reset all
open microphones at all beltpacks on both channels.
Caution: RMK CANNOT be used if power for a channel is derived from
some place other than the local station. The RMK action
momentarily shorts the power line of the affected channel. RMK
only works from a single main station system.
6. Program Enable Switches: The CS-702 has the ability to feed an
external program signal to either of the two channels independently. The
program enable switch allows the program to be turned on, off, or on with
interrupt.
•
In the on position, the program is fed to the channel under all
conditions.
• In the off position, the program is not fed to the channel.
• In the int position, the program is fed except when a talk is activated
to the channel. This program interrupt or IFB function can be used
for talent cuing and dressing room show monitor applications.
7. Program Feed Level Controls: Each channel has a program feed level
control that sets the amount of program being sent to that channel when
the program is activated.
8. Headset Connector: The headset connector is located on the front panel.
All Clear-Com headsets are recommended for use with the CS-702. The
following is a description of the characteristics of a suitable headset:
