Supermarket PTT Microphone Transceiver

Designed for systems that use a large number of Redback C0325/6 mics such as supermarkets and hardware stores. This design is very unique in that it allows you to install unlimited PTT mics on a single circuit, but only allow one mic at a time to operate. Cabling can be loop in/loop out and allows for “tee” offs to remote points if required. When a microphone is in use, the system “locks out” all other connected microphones. One mic can be set to have priority and will override all other mics, even if another is in use.
