QSC DSP-3 2 Channel Digital Signal Processor




-Dual-Independent Channels of DSP -Features 48 kHz / 24-Bit Converters -Electronically Balanced Inputs -Contact Closure to Trigger Gain Changes
QSC DSP 3 2-Channel Digital Signal Processor DSP-3 (Digital Signal Processing) After three decades of developing pioneering audio products and systems, QSC raises the bar once again, setting a new standard in signal processing with the new DSP-3 Digital Signal Processing Module. The DSP-3's two channels of independent signal processing deliver more power, flexibility, and features-in short, more of everything you really need in a DSP-for less. Simple to install and compact, the DSP-3 is the advanced and affordable digital signal processing solution for your audio system. If you would like to purchase a DSP-3 module, please call our sales department at: 800-854-4079. Powerful The DSP-3’s powerful processor allows you to perform a wide range of signal processing functions. Whether you need speaker crossovers, EQ, time delay, or subsonic filters, the DSP-3 is as flexible as your systems's needs. Configurable The DSP-3’s processing horsepower is dynamically assignable so you’re not locked into a fixed configuration. Simply plug your laptop into its RS-232 serial interface and use QSC's powerful configuration software. You can easily configure multiple processing functions and signal flow with "click-and-drop" simplicity. The DSP-3 also allows real-time control or set-and-forget convenience. You can even save each configuration on disk for future recall. Versatile Getting attached to the DSP-3? Then you’ll be glad to know how easily it attaches to most two-channel DataPort-equipped QSC amplifiers, including the CX, DCA, and new PowerLight 2—without taking up extra rack space. Or use multiple DSP-3s with our rack-mount panel kit to create a stand-alone DSP solution that interfaces with any amplifier or system.
