Engineered and designed with the latest technology in mass notification control systems; when paired with a HyperSpike® MA series speaker, the Encompass Amplifier Cabinet is optimized to produce clear and authoritative voice commands with an acoustic footprint of up to 12 square miles.

The cabinet automatically switches to the best power source, performs self-diagnostics, and reports status to the outside world through industry-standard Form C relay fault reporting. Packaged in a NEMA 4 enclosure (4X upgrade available) with a pad-lockable door, the Encompass Amplifier Cabinet is ready to be installed in either indoor or outdoor applications.
