Introduction
Specification

DM300 is a 300W active power amplifier module with one input and two outputs that supports DSP function. Its simple software interface can be matched with real-time settings of compressor, limiter, noise gate, parametric equalization, matrix routing, delayer and other functions to provide smooth operating experience, and the RJ45 network port can transmit Dante network audio while supporting multiple devices hand in hand. Also, it has good configurability and extensibility, suitable for various occasions.
