Digital stereo PA amplifier with integral media player in a compact 0.5U rackmount housing. Class-D amplifier section can deliver up to 2 x 55W max. output for background music with a microphone input for announcements or alerts. The media player section can select between USB / microSD mp3 player, FM tuner, Bluetooth receiver, 2 stereo line inputs (rear panel RCA) and another line input on the front panel (3.5mm). Playback can be controlled from the front panel or by the supplied I.R. remote control. Four mounting brackets are provided which enable the A22 to be fitted under a counter top or against a wall for discreet installation. Two A22 units may be mounted side-by-side into a 1U rack space, which can serve smaller peripheral zones in a larger PA installation. Combine with 2 or 4 speaker units for a truly space-saving sound system with comprehensive and easy-to-use functions.
