Looks Can Be Deceiving


Dataport_white_biggerIt may look like any old VGA video connector, but it’s not. DCA and ISA Series amplifiers and DCP, DCM, and DXP processors use a special QSC connection interface called DataPort, which enables DSP crossovers, speaker-specific EQ, and monitoring and control of amplifier and loudspeaker functions on a single cable. Although many off-the-shelf VGA cables may work with satisfactory results, the QSC DataPort specification requires that all 15 pin conductors be present and that all audio I/O conductors be shielded. Many VGA cables use only 7 pins. If pins 5 or 10 are tied to ground, damage to amplifier may result. Therefore, only QSC supplied DataPort cables should be used.
