DSP-30 - Batts Audio, Video and Lighting


QSC Audio, Inc.

Computer Configurable Digital Signal Processor
Featuring intuitive PC system configuration combined with "set-and-forget" convenience, the DSP-30 unites easy-to-use, customizable, two-channel digital signal processing (DSP) with a simple preset selection interface that requires only two buttons. It can be used with all amplifiers and is housed in a 1RU, 19-inch rack-mount steel chassis. Sampling frequency is 48 kHz with 24-bit resolution. Dynamic range is greater than 95 dB. Rugged and dependable in the spirit of all QSC professional audio products, the DSP-30 is well suited to a variety of applications including mobile DJ, club PA, and pro touring.

The DSP-30's powerful processor enables a wide range of signal processing functions. Whether you need speaker crossovers, EQ, time delay, or subsonic filters, the DSP-30 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-30'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 DSP-30 provides eight fully configurable user presets, selectable from front-panel switches.

The power and flexibility of the DSP-30 eliminates the need for individual outboard signal processors—reducing cost, space, and installation time for almost any application. Housed in a 1RU, 19-inch rack-mount steel chassis, it can be used with all audio systems.
