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.

Lightweight power amplifiers in a 19″ rack-mountable housing for generating high sound pressure levels in medium to large sound reinforcement systems. H-series amplifiers employ a new hybrid class-H architecture, which combines the streamlined efficiency of a digitally controlled power section design with the power delivery and stability of a professional class-H output stage. Comprehensive internal protection monitors any thermal or overload conditions, automatically mutes at power on/off and provides active inrush limiting. A digital display continually shows the supply voltage, internal temperature and output level. A fully balanced signal path has 3 switchable input sensitivity levels to match different audio sources and the amplifier section can be set to operate in Stereo, Parallel or Bridge modes. A switchable 120Hz low-pass filter can be selected for use with subwoofers, avoiding the need for a separate crossover and saving additional expense and rack space.

High power class-D 100V line slave amplifiers in a rack-mountable housing. Slave inputs accept standard line level audio from a mixer or RM series mixer amplifier. Slave outputs can be cascaded onto further RS slaves to build larger systems. All line level inputs are connectable via RCA sockets or hard-wired via removable screw terminals. A further removable screw terminal is provided for 100V input, which enables the RS series slave amplifier to extend an existing 100V installation by connecting directly to the 100V speaker feed, or indeed from a long distance 100V feed using standard double-insulated cable. A 24V terminal is provided for connection to a security or alert panel to mute the output if required during alarm triggering. Speaker outputs are either 100V or low impedance (switchable on RS121 and RS241) which is stable down to 2 Ohms, enabling multiple low impedance speakers to be connected if preferred. Designed to power medium to large installations from a mixer output or to expand existing systems.
