L1400 450W-450W 4ohm (280W-280W8ohm) COMPACT MODERN DESIGN Compact size (2U-Rack Height) with up to 1200W per channel@2ohms these amps save valuable rack space without compromising power output. HIGH CURRENT TOROIDAL TRANSFORMER A high-current toroidal transformer saves rack space and minimizes hum and noise. EXCELLENT SOUND QUALITY The low T.H.D.(0.05%) and high damping factor (400 or higher) gives excellent sound quality. 2 STAGE POWER SUPPLY The high-power units (L1800 and L2400) have a 2-Stage Class-H design that maximizes their performance. EQUIPPED WITH 30Hz or 50Hz HPF All amplifiers are equipped with high-pass filters on each channel to help maintain sound quality, yet help protect the loudspeakers. EXTENSIVE PROTECTION CIRCUITS Extensive protection circuits monitor over voltage/current conditions, overheating, output shorts, and DC voltage to improve performance and reliability. CLIP-LIMITER CIRCUITS Clip-limiters on each channel are provided to help prevent distortion due to excessive signal levels. L.E.D FUNCTION DISPLAYS Power, Clip limiter, Signal, Protection, Mode (Parallel/Stereo/Bridged) LEDs on the front panel indicate the status of the unit in operation.
