High Power 100W Mono Digital Amplifier Board TDA7294 High Fidelity Audio Amplifier Board Module TDA7293Item NO.: XH-M170

100W Mono Digital Amplifier Board

Product Information:

The internal structure of TDA7293 is divided into three stages: the differential input stage is composed of bipolar transistors, and the drive stage and power output stage use FETs. This structure can integrate the advantages of bipolar transistors in low noise and power FETs in linearity, temperature coefficient and timbre. The voice is beautiful, taking into account the advantages of bipolar signal processing circuit and MOS power tube, and it has the advantages of low distortion, low noise, high withstand voltage, switch mute, overheat protection, short circuit protection, etc.

Notes For Use:

Three wire transformers must be used. Double 12 to 32 transformers can be used. Heat sinks must be attached by yourself. Don't ask why. If it doesn't work, it doesn't work. Don't talk about theory. Neither DC nor batteries can work. If they are connected, they will explode. Neither DC nor batteries can work. If they are powered on, they will burn.
