However, many customers have purchased the unit for interoperability (repeating) purposes. The unit connects four radios to one microphone and two speakers. Specific features such as crossband repeating of up to 4 radios (Selectable COR or VOX operated), hook Switch, Select/Unselect audio control and muting, and PA output make the unit more than a "microphone switch".
The NCS-C250 can be configured in systems to provide for sharing of radios between multiple units thereby reducing the number of radios required, resulting in a reduction of overall system cost. (Please see Application Note NCS-AN-101 for further information.)

The NCS-C250 and NCS-C251 are available with two optional features to enhance their operation. Both options are factory installed.

The Sidetone signal is also output to the selected speaker to allow remote monitoring or recording of both sides of the radio communications. This feature can be enabled or disabled by the operator.
