LD Systems SP44K Features

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 LD SP44K 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.
