The PA2B is a compact-sized digital amplifier (Class-D) with 3 inputs (2 lines 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.
- 2 x 20 Watt at 4 ohm as the default amplifier output.
- Bridge connection function. User can switch the PA2B to be 1 x 40Watt at 80hm by bridge connection.
- Two stereo audio inputs, switchable by button, IR remote and RS232.
- Volume /Base/Treble controllable by buttons IR remote and 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 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 and this allows multiple PA2B to be powered on simultaneously without overloading power circuits.
- Convection cooled, the fan is not needed.
- Anti-static case design: providing good protection for long-term and stable performance.
