Six-zone voice evacuation amplifier — EVAC, paging, PA and background music in one unit.
An all-in-one digital voice evacuation system combining an EVAC controller, paging system, PA and background music in a single chassis with a built-in 500W six-zone Class-D amplifier. Two independent SD-card players handle evacuation and alert messages, six zones carry AB speaker line supervision, and the system scales to 120 zones through cascaded routers.

Note: the source specification table gives the model as “SR-65000” and lists 8-zone speaker outputs against a 6-zone description — likely a typo in the source. All figures are nominal, per manufacturer data.
