The DPX-4 allows remote rack mounting of QSC DataPort-compatible accessory modules such as the DSP-3 and DSP-4 digital signal processors. The bracket allows accessory modules to be used in a standalone configuration with QSC four-channel, PowerLight, or non- DataPort amplifiers, including non-QSC amplifiers. As many as four modules can be mounted to the bracket.

The bracket fits a standard 19" equipment rack and occupies 3 rack spaces. The top flange has sets of holes for securing your cabling with wire ties.The bracket may be mounted on either the front or rear rails of an equipment rack. The rack ears are adjustable, so its mounting depth can range from approximately 1.75 in (45 mm) to 4.72 in (120 mm).

The module’s DataPort connector is accessible through the rectangular opening in the bracket. Connectors, switches, LEDs, and other features located on the “outward” side of an accessory module are accessible even when the accessory is mounted to the bracket.

The interconnections an accessory module requires depend on the type of module and the type of amplifier it is used with. Accessories such as the DSP-3 and DSP-4 have their own audio signal inputs.


  • Allows remote rack mounting of up to four two-channel accessory modules
  • Up to eight channels of processing in 3 rack spaces
  • Adjustable rack ears for variable mounting depth
  • Additional holes for securing cabling with wire ties
