Route-r to Success for ASL
Tuesday, 30 January 2001
The latest product to be available from ASL is the VAR-4 Digital Audio Router. This unit uses digital signal processing to provide a self-contained Public Address/Voice Alarm control system and includes built-in digital message storage for emergency or routine announcements. It allows connection of up to six audio inputs routed to four outputs and for the monitoring and control of up to 64 amplifier mainframes (V400) and associated amplifier interface card/surveillance units. Each mainframe connects to the VAR-4 via an Audio-CAN serial data network and audio monitor bus. The router includes digital storage for 2 x 32-second emergency messages and 2 x 10-second test messages, and provides four microphone inputs, typically for two fire microphones and two general purpose paging microphones. Two connections are provided for background music sources, either of which can be selected for routing.
