Supreme audio quality, Digital processing

Emitter Vehicle Intercom System is engineered to solve the problem of communication in high-noise environments such as in Fire and Rescue vehicles, mobile machines, ambulances, etc.
The supreme audio quality is achieved with digital audio transmission which is much more immune to electrical noise and other disturbances than analogue transmission. Digital audio processing, automatic gain control (AGC), gate functionality and digital filtering improve sound quality on all levels.
INTERCOM consists of two main units and supporting components. Regarding mounting location, one unit, usually mounted in the cabin, is marked as the “indoor/master unit” and the other one as the “outdoor/slave unit”. Each unit has its own specific supporting components. The indoor/master unit has an integrated microphone, optional external gooseneck microphone and external 15 W speaker. The outdoor/slave unit has an external handheld unit with an integrated microphone and speaker, external 15 W speaker and 1 A output for external ring indication lamp or a buzzer.
