If the DSP-3 is directly mounted on a 2-RU QSC DataPort equipped amplifier, this connector plugs into the amplifier’s DataPort connector.
If used with 3-RU QSC DataPort equipped amplifi- ers, the DSP-3 will need to be remotely mounted and a male-female DataPort cable used to inter- connect the amp & DSP-3.
If used with a non-DataPort amp (QSC or other), this connector will not be used.
