Product introduction


MP73X2 is a dual microphone amplifier. Its fully discrete signal path with six separate transformers for the mic input, line input and line output. Each transformer enhances performance in a way. Its stereo sound quality makes the output sound more smoother, natural and warmth. Via various button and knob to adjust the signal which offers ideal sound quality and avoids sound distortion. Its heavy-duty shell makes product sturdy and durable.



Feature : 

  • Its shell adopts dust-free spraying processing makes product concise and better adhere
  • The chassis is made from high quality steel to provide extra shielding against stray magnetic and RF
  • Combines with unique circuit to amplifier ensures output signal more purity and clear
