Power amplifiers make the audible to listeners. It is the final electronic stage in a typical audio playback chain before the is sent to the loudspeakers and speaker enclosures.


Features:

  • Digital amplifier has a higher overload capacity than analog amplifier, and it won't cause crossover distortion, transient inter modulation distortion and you don't have to worry about the loudspeaker internal resistance.
  • It supports V4.0 audio input and DC 8V to 25V voltage input.
  • Integrated amp uses NE5532 pre-amp, and TDA7492 chip for dual channel of 50W+50W power output.
  • Sound quality is very good by using this audio power amplifier module.
  • Applicable speaker impedance are 4, 6, 8ohm, great for turning normal speaker into speaker.
