Features and/or Benefits
Enhanced Intelligibility
Mic preamp with limiter and proprietary speech-shaping circuits improve the quality of words spoken into the system.
Eliminate Noise
Remote Mic Kill turns off the microphone talk circuits of all Clear-Com beltpacks eliminating noise from the open headset microphones.
Control Individual Voice Level
Individual Sidetone control allows the operator to vary the level of his or her own voice as heard in the headset.
Power Supply Protection
In the event of a short circuit or current overload, the protection circuit with shut down the output to avoid damage and will automatically restore the system power as soon as the fault condition is removed.
