Flagship Power & Precision – Delivers ultra-high power with low distortion, perfectly matching the extreme dynamics of P Series speakers and subwoofers.

 Advanced DSP Control – Built-in 4×4 matrix routing, selectable inputs/outputs, and flexible crossover modes for total system customization.

 Pro-Grade Tuning – Supports both FIR and IIR filters for precise EQ and sound shaping across complex multi-channel setups.

To fully utilize the powerful performance of P series main speakers and subwoofers, a high-power amplifier with strong driving force is essential. High power with low distortion is often a contradiction. We need to ensure that the power amplifier has low distortion while maintaining high power because clean reproduction with extreme dynamics is our overriding objective. PA4000DSP is our flagship amplifier to reach it. We matched its high power with sophisticated DSP functions: 4x4 input and output matrix to freely control the signal path through software, and perform input and output selection. Advanced EQ algorithms support FIR and IIR filters, and optional frequency division mode.
