ماژول آمپلی فایر 2X210W وات استریو XH-M251

Introduction

XH-M251 Stereo audio amplifier with very compact size but incredible power of 210+210W, thanks to the TDA8954 chip, manufactured by NXP Semiconductors. It can be connected to devices such as PCs, notebooks, tablets, and smartphones via a 3.5mm audio input jack. Integrates on PCB one potentiometer for the listening volume regulation. High power output, sound clarity and compact size make it a very versatile product.
TDA8954 is a new type of high-efficiency class D audio power amplifier with a typical output power of 4 Ohms at load.
This product uses the double power supply transformer with a power supply range from 12V to 28V also can work.
Normally, with full differential input, high power output in double AC28V, RL=4 Ohms, as a dual-channel 2 * 210W.
Because of the BD modulation in normal working noise is very low, the sound of a zero dead-time PWM output.
