PREMIUM POWER AMPLIFIERS


The LD Premium SP series is a range of no-compromise professional power amplifiers combining high efficiency, reliability and versatility in a compact lightweight design. Available in 2 and 4-channel models the SP Series delivers superior audio performance for touring and installation sound reinforcement. The SP series amplifiers feature a switch mode power supply with Class H design, a 20Hz – 20kHz bandwidth with low THD and crosstalk, a damping factor greater than 500, and excellent S/N ratio. Reliable, long-life operation is ensured by heavy duty engineering, high quality components and a comprehensive safety package including soft start with turn-on muting, PMS™ power management and SSP™ safe operation amp Sentry Protection. The intelligent clip limiter ICL™ prevents speaker damage while maintaining signal integrity. Protection circuits against DC, thermal and power supply overload are implemented. A switchable subsonic filter and a 3-position gain switch offer variable amplifier adjustment. With up to 2.950W per channel at 2 Ohms, SP Series amplifiers provide massive output and serious value for demanding applications.
