DP26+ 2-Input 6-Output Professional DSP Loudspeaker Management Processor
Product Overview
The Haozhiseng Audio DP26+ is a professional 2-input, 6-output digital loudspeaker management processor designed for PA systems, live sound reinforcement, touring systems, rental applications, houses of worship and fixed audio installations.
Featuring a 96 kHz sampling rate, 24-bit A/D and D/A converters, and a 32-bit DSP processor, the DP26+ provides precise signal processing with wide frequency response, low distortion and excellent channel separation.
Each input and output channel includes comprehensive processing functions such as parametric EQ, gain, delay, polarity, compressor and mute control. Six independently configurable outputs also provide flexible input routing, crossover filters and limiters for accurate loudspeaker system management.
PC control is available through front-panel USB, rear-panel RS-485 and TCP/IP connections.
