A-series Commercial Mixer-amplifiers
A-series mixer-amplifiers with switchable stereo or dual mono speaker outputs. Each speaker output has a stereo input source that can be selected between the internal audio player or three external stereo line inputs and even a digital optical input for AV applications. The inbuilt media player section offers playback of mp3 audio tracks from USB drive or microSD card and also has a B/T wireless receiver and FM radio tuner. Each speaker output zone has a wide ranging power capability from background music up to higher sound pressure levels, with Bass, Treble and Master Volume controls for independent sound management. Two microphone inputs have individual level controls and can be set to override the stereo line input for voice announcements. Emergency muting can be actuated from an alarm panel via the 24V EMG MUTE contacts on the rear panel. The A-series commercial amplifiers offer sophisticated functionality and power in a convenient 2U rack package with a comprehensive and accessible control surface. Each variant of this range is appointed to meet the needs of different sized installations with flexible setup options to serve various system topologies.
