The ALF-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 is a good application in different spaces, including classrooms, small meeting rooms, lecture halls, bars, pubs, etc.

Features:

• 2 x 20 Watt @ 4 0hm as the default amplifier output
• Bridge connection function. Users can switch the PA2B to be 1 x 40 Watt @ 8 0hm by bridge connection
• Two stereo audio inputs, switchable by panel button, IR remote and RS232
• Volume / Bass / Treble controllable by panel buttons IR remote and RS232
• MIC port can support balanced/unbalanced signal, suppresses the external noise effectively. Line audio output via 3.5mm jack, with controllable volume
• 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. 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, a fan is not needed
• Anti-static case design: providing good protection for long-term and stable performance
