AS-AMP1 is a small digital amplifier (Class D), with EQ control and MIC mixer function. It is in small enclosure but with powerful functions, including bridge connection, dual-mono, EQ control, microphone mixer, etc.
Applications include classrooms, small meeting rooms, lecture halls, bars, etc.

  • 2x20Watt @ 4(Ohm) as the default amplifier output
  • Bridge connection function. The user can switch the AS-AMP1 to be 1x40Watt @ 8(Ohm) by bridge connection
  • Dual-mono function. The user can sum up the stereo audio to two times mono audio
  • Microphone mixer function. The microphone will be mixed to the line audio output, and separately controllable
  • Two stereo audio inputs, switchable by button, remote or RS232
  • Volume/Bass/Treble controllable by buttons or RS232
  • Line audio output, with volume controllable
  • Optional control solution, by IR remote or volume panel
  • RS232 control with smart feedback
  • Antistatic case design: providing good protection for long-term and stable performance
  • Internal international power supply (100Volt~240Volt AC, 50/60Hz) For worldwide compatibility
  • Fast switching speed
  • LED indicator, for power and working status
