General Guidelines to using the DataPorts on the CX168
1.Each channel pair (
2.The DataPort for channels 1 and 2 has a special function on the CX168. It is the ‘master’ DataPort for controlling AND reporting power supply status of the amplifier. It is only possible to control and report the status of the power supply using the Ch.1 & Ch.2 DataPort.
3.In order for the Ch.1 & Ch.2 DataPort to control the power status of the amplifier, the
4.The DataPort connection can be used for amplifier status monitoring only, using the terminal block inputs for supplying input signals to the amplifier. Ensure that the DataPort connection supplies NO INPUT SIGNAL when operating in this fashion. If signal is applied to both the DataPort and the terminal block input connector at the same time, the signals will be summed and amplified. The result may be undesirable.
5.If using the DataPort for supplying the audio input signals to the amplifier, we don’t recommend using the terminal block input connectors, even if they are connected to
6.If using the DataPort for supplying the audio input signals to the amplifier, do not use the unused terminal block inputs for
7.The heat sink temperatures of the CX168 are reported on the first channel of each channel pair’s DataPort. In other words, to monitor all four heat sink temperatures, all four DataPorts must be connected to the monitoring device (such as QSC’s CM16a). Temperatures will be reported on channels 1, 3, 5 and 7.
