Descriptions:
VA-6100MS changeover is an integrated controller supporting main and backup amplifier switching, speaker circuit grounding detection, open circuit and short circuit detection; compatible with 3/4 wired volume controller wiring, no need extra wiring or power supply; combining 8 programmable dry contact or wet contact trigger inputs and 8 programmable on-line output signal. It works with class D amplifiers, traditional amplifiers to provide a safe, affordable solution to the PA & Voice Alarm system.
Features:
* 2U cabinet design, high integrated, and modularized design.
* Support speaker circuit grounding, open circuit and short circuit detection.
* Support 3/4 wired speaker loop wiring.
* 8 programmable trigger input interfaces.
* 8 programmable trigger output interfaces.
* Support power amplifier enter power saving mode to save energy when no signal input.
* Support the connection with linkage fire alarm controller to realize fire alarm linkage control.
