LD Premium LDSP44K 4-Channel Power Amplifier

The LDSP44K is a professional 4-channel power amplifier offering amazing value and versatility in a compact lightweight Class H design. Suitable for touring and installation sound reinforcement it delivers a maximum of 4x 980W into 2Ohms and 2x 1.960 in 4Ohms stereo bridge mode.

Featuring a high efficiency switch mode power supply the LDSP44K provides a 20Hz – 20kHz bandwidth with low THD and crosstalk, a damping factor higher than 500, excellent S/N ratio and 3 switchable sensitivity levels.

Reliable performance is ensured by heavy duty engineering, high quality components and comprehensive protection including soft start with turn-on muting, PMS™ power management, SSP™ (Safe operation Sentry Protection) and ICL™  (Intelligent Clip Limiting) to maintain 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.
