The QSC DSP-3 Digital Signal Processing Module features two channels of independent processing that provide plenty of power, flexibility and functionality. The unit is compact, easy to install 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. Plus, the DSP-3's processing power is dynamically assignable, which means you'll never get locked into a fixed configuration. Using the configuration software, you can easily configure several processing functions and signal flow with drag-and-drop convenience. You can save each configuration on a disc as well. The DSP-3 even affords real-time control. It's also designed to attach to most two-channel QSC amplifiers with a DataPort. Using the DataPort attachment feature won't take up extra rack space. However, if you're using an alternate amplifier, QSC makes a rack-mount attachment bracket for up to for DSP-3 modules.
