The QSC DSP-30 Computer Configurable Digital Signal Processor features two-channels of customizable digital signal processing (DSP) with a simple preset selection interface that requires only two buttons. It works with all amplifiers as well. The processor uses balanced Neutrik Combo XLR and 1/4" inputs, as well as XLR outputs. It's housed in a 1RU 19" rack mount steel chassis. Plus, it's easy-to-install, easy-to-use and very affordable. Each channel includes crossover filtering, multiple parametric EQs, shelf filtering, tone generation, noise generation, precise attenuation, multiple delays up to 910 ms, mixing, compression, limiting and more. The DSP-30's processing power is dynamically assignable as well, which means you'll never get locked into a fixed configuration. When you're using the configuration software, you can easily configure several processing functions and signal flow with drag-and-drop convenience. You can even save each configuration on a disc. The DSP-30 affords real-time control. It offers easy PC connection with a front panel RS-232 and it features set-and-forget convenience. The DSP-30 The DSP-30 provides eight fully configurable user presets that are selectable from front-panel switches. Its power and flexibility even eliminate the need for any individual outboard signal processors, which saves space and money.
