DIRECT MOUNTING THE DSP-3 TO 2-CHANNEL, 2 RU QSC DATAPORT EQUIPPED AMPLIFIERS (CX, DCA, Powerlight2)
The DSP-3 mounts directly to the rear of 2-channel, 2-RU, DataPort equipped QSC amplifiers.

•All filters off •Clip limiter off •Mode set as required
2- Align the DataPort plug on the back of the DSP-3 with the DataPort jack on the back of the amplifier and gently push the DSP-3 to seat
the connector.
3- Install the two #4-40 screws to secure the left side of the DSP-3 to the amplifier. These two long screws pass through the DSP-3 and
thread into the inserts on the DataPort (HD15) jack. (see below). Use a #1-size phillips driver; be sure not to overtighten.
Be sure to secure the DSP-3 using all three mounting screws. The DSP-3’s “backside” DataPort connector can be
easily damaged if the DSP-3 is twisted and there are no supporting screws to properly secure it to the chassis.
