QSC DSP-30 1RU 2-Channel Digital Signal Processor, 600 Ohms Output Impedance, 20Hz-20kHz, Balanced Neutrik Combo Input, 3-Pin Male XLR Receptacle Output

Featuring intuitive PC system configuration combined with set-and forget" convenience, the QSC 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" 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.

Powerful
The DSP-30's powerful processor enables a wide range of signal processing functions. Whether you need speaker crossovers, EQ, signal delay or infrasonic filters, the DSP-30 is as flexible as your system's needs. Each channel includes crossover filtering, compression and limiting, multiple parametric EQs, precision attenuation, shelf filtering, mixing, multiple delays (up to 910 ms), tone and noise generation.

Configurable
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.

Cost-Effective
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.
