LD Systems DSP 45K - professional audio amplifier with 4 channels and extensive DSP control. Designed for touring and concert applications, it delivers 1200W RMS per channel or 2 x 2400W RMS in bridge mode. The Class H topology and PFC-corrected switch mode power supply provide a wide dynamic range and excellent transient response.
DSP 45K features multiple protection circuits, including a delay at power-up, overcurrent, thermal protection, and short-circuit, current limiter, and clip limiter to prevent overloading the speakers. Together with the two temperature-controlled fans, DSP 45K ensures exceptional reliability.
The integrated 24-bit DSP allows precise control with FIR and IIR filters, parametric EQ, crossover, delay, and RMS and peak limiting functions, while the configurable, savable, and password-protected presets ensure quick setup. DSP 45K includes a library of presets for LD Systems speakers, and the included software allows monitoring and control via computer.
