Automatic Clip Limiter. Adjusts the final amplification level to the amplitude of the input signal. This prevents “saturation” distortion during high-power usage. Crossover 75Hz - 1200Hz. -Independent for each signal allowing fluent regulation of frequency division -Easy configuration of bi-amp systems. Multi-level protection system. -Thermal and overload protection. Temperatures over 100°C or exit current overload will trigger automatic power cut-off. -Automatic return-protection in case of RF output. -Automatic power-down of the amplifier in case of short circuit Cooling extractor fans. Two stage cooling system. Fan extraction rate set at low level when radiator element is below 60°C, and high rate above this temperature. Automatic silent power switching. Prevents dangerous signals being delivered to the speakers during turn-on and turn-off. The integrated system turns itself on and off electronically and silently to protect the amplifier and speakers. Output power. Varies according to model, connection and configuration from 150w to 1600w. Constant operation with 2ohm load. LX1100 and LX1400 models allow amplification of speaker sets with a combined impedance of 2 ohms. Double input sockets, XLR and Jack types. Crossover output sockets. Allows the control of additional amplifiers with complimentary signals. Reliable Speakon safety output sockets. Toroidal transformer. Minimises mains-hum allowing for silent operation of high-voltage circuitry. Mosfet transistors. High quality mosfet transistors are used to produce distinctive bass and treble sounds. Anti-dust filters. Minimizes the risk of dust and dirt from entering the apparatus.
