MP-A2B

MP-A2B is a compact-size digital amplifier (Class-D) with 3 inputs (2 line in and 1 balanced MIC). It is integrated with powerful functions, including bridge connection, dual-mono, EQ control, microphone mixer etc. It has a good application in different places, including classroom, small meeting room, lecture hall, bar, pub etc.

  • [email protected] as the default amplifier output.
  • Bridge connection function. User can switch the MP-A2B to be [email protected] by bridge connection.
  • Two stereo audio inputs, switchable by button, IR remote & RS232.
  • Volume/Bass/Treble controllable by buttons IR remote & RS232.
  • MIC port can support balance/unbalance signal, suppress the external noise effectively.
  • Line audio output at 3.5mm jack, with volume controllable.
  • Dual-mono function. User can sum up the stereo audio to two times mono audio.
  • MIC mixer function. The microphone will be mixed to the line audio output, and be controlled separately.
  • MIC input supports 48V phantom power, dynamic MIC and wireless MIC.
  • Auto noise gate. It keeps detecting the audio and MIC input, will mute the output when there is no input.
  • Ultra low inrush current, no need for power sequencing. This allows multiple MP-A2B to be powered on simultaneously without overloading power circuits.
  • Convection cooler, fan is not needed.
  • Antistatic case design: providing good protection for long-term and stable performance.
