Guardian Telecom’s DA388 Distribution Amplifier is a line level pre-amplifier for use in public address and alarm systems. As part of the integrated system, the DA388 recognizes audio inputs – telephone access, background music, voice signals and alarm tones – and boosts the signal before distribution.

The DA388 is designed to prioritize audio input signals and distribute the signal to multiple power amplifiers without degrading audio quality.

The DA-388 Zone Selector is one component in Guardian Telecom’s full line of reliable, hard working PA/GA paging system products – all designed for easy installation and connectability.

Guardian’s trained representatives will work with you to customize a safe comprehensive alarm and public address system for your operations.
