The equipment has two connections for distributed elements in Public Address Systems. It

consists of a line level audio input plus control signals for connecting up to 8 devices in bus mode
"daisy chain", where each device is connected to the next. Both connections are identical and are
interconnected. The ACSI bus supplies remote power to the equipment, see 2.2.8.

The   connection   is   via   ethernet   cable,   T568B   standard.   The   maximum   distance   of

connection for the entire bus is 1000m (3280ft).
