DataPort
The QSC DataPort connection carries input signals, amplifier output monitoring signals, remote amplifier power on/ standby control, amplifier temperature, and more, all on one cable. Each DataPort is clearly marked indicating which channel’s amplifier it should be connected to. Follow the back panel labelling. Connect each DataPort to its respective amplifier’s DataPort.
Connect a DataPort cable from each of the DCM’s DataPorts to each of the system’s DCA amplifiers.
Orient the cable’s HD15 male connector properly and push the connector onto the DCA’s receptacle.
