LD Systems LDDSP 45 K

Introducing the LD Systems LDDSP 45 K 4-channel power amplifier which is ideal for demanding large-scale sound reinforcement with extensive DSP. Designed for concert-quality performance, the LDDSP 45K delivers 1,200 watts per channel (2 / 4 Ohms or 70V) and 2 x 2,400 watts bridged (4 Ohms or 100V).

The high-efficiency Class H topology and switch mode power supply with power factor correction (PFC) provide a wide dynamic range and excellent transient response.

Comprehensive protection circuitry including power-up, DC, overcurrent, thermal and short circuit protection plus current and clip limiters to prevent SMPS overload and loudspeaker damage. Together with a pair of temperature controlled fans, they ensure exceptional reliability in the most demanding applications.

The 24-bit DSP allows precise control with FIR and IIR filters, parametric EQ, crossover, delay, RMS and peak limiter functions. User configurable loudspeaker presets with password protection enable fast setup. The LD Systems® DSP 44 K sports a menu driven 4-line display and rotary encoder with push button switch for easy configuration.

The LD Systems DSP 45 K is housed in a 2U all-steel chassis and weighs just 7 kg. It provides balanced Neutrik® XLR inputs, speakON® output connectors plus USB and Ethernet ports. For optimal speaker performance and safe operation the DSP 45K comes with an LD Systems® loudspeaker preset library and the included software enables computer control and monitoring.
