The system amplifiers use class D adaptive amplifier technology available in 100W, 200W and 400W units in various configurations in 2U 19" rack mount units. There is a family of routers to cater for differing system complexities. The simplest router mixer unit allows for six audio inputs to be routed to the 4 dual audio outputs for dual circuit systems. Expanded units provide 12x12 or 20x20 capacity, and can control up to 64 amplifiers using the proprietary Audio-CAN data network. The basic routers also include digital storage for 2 x 32 second emergency messages and 2 x 16 second test messages. The 12x12 unit provides four out of each message type, and the 20x20 provide six of each message type. The routers are provided with a modem interface to allow the remote diagnostics, fault-finding and configuration to be carried out from a remote location.
