Overview

The DPA2448QRT is a high-end 2-IN/4-OUT digital speaker management system designed to deliver maximum versatility and sonic purity for both live sound reinforcement and fixed installations. Managed by a powerful Marani M716 DSP engine, this unit offers full 96kHz processing and high-performance 24-bit AD/DA converters to ensure pristine audio quality. It features two analog inputs, four analog outputs, and a digital S/PDIF input, supporting a full matrix mixing mode that allows inputs to be routed and mixed in any ratio to any output. With a robust feature set including noise gates, RMS compressors, and internal noise generators, the DPA2448QRT provides all the tools necessary for precise system tuning.

For comprehensive control, the DPA2448QRT offers extensive processing options for every channel. Each input is equipped with a 30-band parametric EQ, three all-pass filters, and configurable delay up to 480ms, while each output features a 7-band parametric EQ, peak limiter, and crossover filters with slopes up to 48dB/Octave. The system can be configured locally via the front panel interactive LCD or remotely through USB and TCP/IP connections. The dedicated PC software allows for simultaneous control of up to 32 units, making it an ideal solution for complex, multi-zone audio setups.
