Application Information

As design improvements are continuous, the following information is subject to change. Contact QSC for current information.

QSC’s DSP-4 Module has been designed to attach directly to the DataPort connector of QSC’s CX, DCA, and Powerlight 2 series amplifi- ers. When attached to CX, DCA, and Powerlight 2 amps manufactured 08/99 and later, the module receives its power through the DataPort from the amplifier. Modules connected to earlier models of those just mentioned and all Powerlight amplifiers (the “non-2’s”) require an external DC supply (available from QSC).

TO CLARIFY: CX, DCA, and PL2 amps made prior to August 1999 DO NOT provide adequate power supply voltage to the module, requiring the use of the same type of external DC supply as used with Powerlight amplifiers. The amps in question will have a serial number PRIOR to 0899XXXXX, where the first four digits of the serial number are the MMYY datecode. Again, the mod- ules WILL work with these amps, but will require the use of our external power supply.

•Full feature set, Direct-mounting, No external power required, No special interconnect cables required for the following QSC power amplifiers with serial numbers of 0899XXXXX and later, where the first four digits of the serial number are the MMYY datecode :

CX series: CX302 - CX1202V (all)

DCA series: DCA1222, DCA1622, DCA2422, DCA3022, DCA342

PL2 series: PL224, PL230, PL236, PL218

PL2A series:All

•Remote Mounting Required, QSC DataPort Cable required: Full feature-set, no external power required.

CX series: CX204V, CX254, CX404, CX168

DCA series: DCA1644, DCA1824

•Remote Mounting, QSC DataPort Cable and External Power required: Full feature-set.

Powerlight series:PL1.0 through PL4.0 (all)

PL6.0 and PL9.0 require modified DataPort cable between DSP-4 and amplifier. Powerlight 6.0 and 9.0 MUST have pin #9 removed from the Amplifier-to-DSP DataPort Cable (DPX-2) before use!

•Remote Mounting and External Power required. No DataPort Connection possible, Power Limiting not avail- able.

ISA series: The ISA amplifiers have a “V2” DataPort that may be used for audio inputs only.

MX series: All

PLX series: All

RMX series All

USA series: All

ALL non-QSC amplifiers can be used with the DSP-4.
