Data port
The Data port located on the rear panel of the ALC2, is the connection for remote controlling the amplifier. Through the 15 pin high density D-connector, signals
indicating the status of the ALC2 are available for the remote control unit. The input signals to the amplifier can also be supplied through this connector.
For cinema applications, the Data port is compatible with existing D-connector connected cinema monitors. In that application in addition to the data port
connection only the AC mains and loudspeakers need to be connected, and so the Data port caters for reduced set-up and installation time and standardised in-
and output levels.
