DSP 44 K LD SYSTEMS 4-channel DANTE™ amplifier

Description

DSP 44 K LD SYSTEMS 4 channel amplifier

The LD Systems® DSP 44 K is a professional 4-channel power amplifier suitable for use in a network, for demanding large-scale sound reinforcement. It includes extensive DSP control and Audinate's Dante™ network technology, a self-configuring solution for distributing digital audio over Ethernet with extremely low latency. Designed for concert performance, the DSP 44 K delivers a massive 1,200 watts per channel and 2 x 2,400 watts bridged.

The highly efficient Class H topology and switch mode power supply with power factor correction (PFC) ensures a wide dynamic range and excellent transient response. The DSP 44 K features comprehensive protection circuitry including power-up, DC, overcurrent, thermal and short-circuit protection plus current and clamp limiters to prevent SMPS overload and speaker damage. Together with a pair of temperature-controlled fans, they provide exceptional reliability in the most demanding applications.

The 24-bit DSP enables precise control with FIR and IIR filters, parametric EQ, crossover, delay, RMS and peak limit functions. User configurable speaker presets with password protection allow for quick installation. The LD Systems® DSP 44 K features a menu-driven 4-line display and a rotary encoder with push-button switch for easy configuration. The Dante™ interface enables immediate integration into networks using the Dante™ protocol, and the included software enables computer control and monitoring.

The LD Systems® DSP 44 K is housed in a 2U all-steel chassis and weighs just 7 kg. It offers balanced Neutrik® XLR inputs, speakON® output connectors plus USB and Ethernet ports. For optimum speaker performance and safe operation, the DSP 44 K comes with an LD Systems® speaker preset library.
