DP24+ 2-Input 4-Output Professional DSP Loudspeaker Management Processor
Product Overview
The Haozhiseng Audio DP24+ is a professional 2-input, 4-output digital loudspeaker management processor designed for PA systems, live sound reinforcement, touring applications, and fixed installations.
Featuring a 32-bit floating-point DSP engine and a 96 kHz sampling rate, the DP24+ provides accurate signal processing and flexible system control. Its integrated EQ, crossover, delay, limiter, polarity, gain, and signal-routing functions allow precise optimization of full-range speakers, subwoofers, stage monitors, delay speakers, and multi-zone audio systems.
USB and RS-485 control interfaces simplify system configuration, making the DP24+ suitable for both portable sound systems and permanent installations.
Key Features
