B.    Introduction

 

 

MT-2X04USB is 2CH stereo digital power amplifier with high performance DSP application for stage, professional audio, home hi-end audio and karaoke products. Thanks to the accurate digital signal processing, it is flexible to adapt various sound applications and advantages as bellows:

 

l          Class-D and switching power Design for high efficiency, high stability & lighter weight.

l          Output power setting from 200Wx2CH ~1000W (BTL)

l          On board digital signal processing includes crossovers, compressors,  PEQs(frequency point, Gain, Q value), delay time setting, output limit setting.

l          Easy Graphic User Interface (GUI) Control for DSP parameter adjustment and preset saved/load through USB (what you change through GUI, what you feel synchronously)
