Product Description Digital switching amplifier Rock-solid, ultrastable output power set record marks in terms of flexibility, efficiency and practical use. Whole amp racks of multiple conventional power amplifiers with switching power supplies may be reduced to a mere one to three LEX Class D Digital amplifiers. Apart from these "hard" benefits, they offer many more advantages such as a strikingly audiophile sound reproduction with very precise, deep lows and a superb resolution of midrange and high frequencies. The fact that LEX develops and builds amplifiers in top-notch quality is almost self-explanatory. The uncompromising component selection and a circuit design based on criteria of aerospace technology ensure utmost reliability. Features: Ø Switch-mode power supply for high performance and compact size Ø Class D (digital) output for extremely high efficiency because of less current consumption and heat dissipation Ø Easily handles 2-ohm loads all night long Ø Variable speed fan for low noise Ø Balanced XLR audio input / Speakon Speaker output Ø Switch for mono and stereo Ø Comprehensive front panel indicators including signal (SIG), clip (CLIP), active (ACT) and, protect (PRO) Ø Fully protected circuit design including DC, infrasonic, high frequency, thermal overload and short circuit Ø Clip limiter - prevents severely clipped waveforms from reaching the loudspeakers, whilst maintaining full peak power Ø DC protection - protects against infrasonic signals Ø VHF protection - protects the loudspeakers against strong very high frequency non-musical signals above the audible range. Ø Thermal protection - prevents the amplifier from being overheated Ø Compact size - only 1 U for reduced rack cost and space Ø Light weight - only 9 kg for easier racking and shipping (bigger power model)
