Professional power in a compact modular system

Park Audio engineers have combined all the advantages of a line-array system in a compact, modular and surprisingly powerful design: 12,200 watts of professional performance.

Thanks to its active architecture, high-quality components and advanced DSP processing, the D-AR4 provides uniform coverage, high sound pressure and easy configuration for any demanding sound environment.

The system comprises:

  • 4 active NX183-P subwoofers
  • 4 active D2-P line-array modules

For ground-stack deployment, the system includes the D2-TP platform, which allows precise adjustment of the tilt angle.

An optional flying frame can also be ordered for flown installation of the array elements.

D2-P — active constant-curvature line array

This system features two 8-inch loudspeakers and four 1-inch B&C SPEAKERS drivers, with 1,050 W RMS of power and a frequency range from 60 Hz to 18 kHz.

Expandable up to 4 modules, it adapts easily to spaces of any size.

Housed in a sealed metal enclosure, its compact design allows the components to be placed very close together, which:

  • Minimizes phase interference
  • Provides uniform coverage with only -3 dB per metre
  • Reduces the risk of microphone feedback
  • Ensures balanced sound in large venues

Robust construction and consistent performance, even under demanding conditions.

NX183-P active subwoofer

NX183-P — deep bass with amplification and DSP

The NX183-P is a professional active subwoofer designed to deliver deep, controlled low frequencies from 34 Hz to 120 Hz.

It incorporates an 18-inch B&C Speakers driver with a neodymium magnet and 4-inch voice coil, powered by an internal 2,000 W RMS amplifier. Its design delivers a maximum sound pressure level of 133 dB SPL peak, making it ideal for high-performance applications.

The DSP integrated into the amplifier module provides advanced functions for:

  • Crossover filtering and equalization
  • Amplifier and loudspeaker overload protection
  • Optimized presets for creating directional subwoofer arrays (cardioid, end-fire)

Robust, powerful and ready for every type of stage, the NX183-P is the ideal foundation for professional sound-reinforcement systems such as the D-AR4.
