DSP4

With more than three decades of experience pioneering cutting edge audio products, QSC raises the bar once again with the DSP-4 Digital Signal Processing Module. This compact module offers two channels of independent DSP and attaches to the back of most 2-channel DataPort-equipped QSC amplifiers—without occupying any additional rack space.

Capitalizing on the success of our DSP-3, the second-generation DSP-4 provides several enhancements in functionality and performance while also incorporating the universally popular XLR balanced connectors. These enhancements include new A/D and D/A converters for improved signal-to-noise performance and upgraded software that significantly increases the unit’s operational characteristics.

Simple to install, compact, and featuring "set-and-forget" convenience, the DSP-4’s powerful processor enables you to perform a wide range of signal processing functions; and with its new A/D and D/A converters, its noise floor improves. Whether you need speaker crossovers, EQ, time delay, or subsonic filters, the DSP-4 is as flexible as your system’s needs.

Each channel includes:

  • Crossover filtering
  • Multiple parametric EQs
  • Shelf filtering
  • Tone and noise generation
  • Precision attenuation
  • Multiple delays (up to 910 ms)
  • Mixing
  • Compression and limiting

The DSP-4’s processing horsepower is dynamically assignable so you are not limited by a fixed signal chain. Simply use QSC’s powerful PC-based Signal Manager software to easily configure multiple processing functions and signal flow with “drag-and-drop” tools.

The power and flexibility of the DSP-4 eliminates the need for expensive outboard processing gear, reducing cost and installation time for almost any application. The compact DSP-4 also plugs directly into the back of most QSC DataPort-equipped amplifiers for use in systems where rack space is a premium.
