With more than three decades of experience pioneering cutting edge audio products, QSC raises the bar once again with the DSP-4 Digital Signal Processing Module. This compact module offers two channels of independent DSP and attaches to the back of most 2-channel DataPort-equipped QSC amplifiers—without occupying any additional rack space. Capitalizing on the success of our DSP-3, the second-generation DSP-4 provides several enhancements in functionality and performance while also incorporating the universally popular XLR balanced connectors. These enhancements include new A/D and D/A converters for improved signal-to-noise performance and upgraded software that significantly increases the unit’s operational characteristics. Powerful Simple to install, compact, and featuring "set-and-forget" convenience, the DSP-4’s powerful processor enables you to perform a wide range of signal processing functions; and with its new A/D and D/A converters, its noise floor improves. Whether you need speaker crossovers, EQ, time delay, or subsonic filters, the DSP-4 is as flexible as your system’s needs. Each channel includes: - Crossover filtering - Multiple parametric EQs - Shelf filtering - Tone and noise generation - Precision attenuation - Multiple delays (up to 910 ms) - Mixing - Compression and limiting Configurable The DSP-4’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. Cost-effective The power and flexibility of the DSP-4 eliminates the need for expensive outboard processing gear, reducing cost and installation time for almost any application. The compact DSP-4 also plugs directly into the back of most QSC DataPort-equipped amplifiers for use in systems where rack space is a premium. Hardware - Two independent channels of DSP - 48kHz, 24-bit converters - No turn on pops or zipper noise - If the memory or hardware fails, unit turns on muted to prevent driver damage - Host interface via RS-232 or QSControl Audio Network System via CM16a Amplifier Network Monitor - Electronically balanced XLR inputs - Contact closure to trigger preset changes - Post-DSP output signal for daisy-chaining - Peak and RMS meter displays with clip indication - DataPort pass-through compatible with QSControl - Selectable input sensitivity: 1.5, 4, 9, 18 Vrms; - 6, 14.5, 21.5, 27.5 dBu; 3.5, 12, 19, 25 dBV - Output signal gain (to be released)
