iSound PA20

2 x 20 Watt @ 4 0hm as the default amplifier output

Bridge connection function. Users can switch the PA20 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 signals and suppress 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 into 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, and will mute the output when there is no input

Ultra-low inrush current, no need for power sequencing, and this allows multiple iSound PA20 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
