QSC DSP 3 MODULEThe compact DSP 3 Digital Signal Processor module from QSC (www.qscaudio.com) attaches to the back of most QSC DataPort-equipped amps, including the PowerLight 2. The DSP 3 offers two channels of independent DSP, including cross-overs, shelf and parametric filters, signal delay, compression and peak limiting. Function and signal flow configuration are via "drag-and-drop" software using icons and simple drawing tools, interfaced via an RS-232 serial port. The software allows real-time control, and all settings can be stored for later recall. Additional DSP 3 functions include a two-to-one mixer, signal splitter, signal mute, 0.1dB attenuation steps, polarity reversal, 24-bit/48kHz converters, built-in tone and noise generators, and selectable 1.5v/4v/9v/18v input sensitivity.
