Product Overview

The DP4080 is a professional-grade digital audio processor by Harmonai, engineered for high-fidelity sound systems. It integrates FIR (Finite Impulse Response) filters, AES/EBU digital audio inputs/outputs, and 48V phantom power—providing a complete solution for audio signal processing and speaker management.

FIR Linear-Phase Filtering

Leveraging advanced FIR filtering technology, the DP4080 ensures full-bandwidth linear-phase response—effectively eliminating phase distortion caused by traditional IIR filters. This delivers purer, more natural sound reproduction, preserving audio integrity in both music playback and live sound reinforcement applications.

AES Digital Audio Interface

Equipped with standard AES/EBU digital audio inputs and outputs, the DP4080 supports lossless digital signal transmission—significantly reducing noise interference common in analog signal paths. Ideal for large-scale installations demanding the highest signal fidelity.

Built-in 48V Phantom Power

The unit features integrated 48V phantom power, enabling direct powering of condenser microphones without external power supplies—simplifying system cabling and enhancing overall reliability.

Speaker Management System

Includes a professional speaker management system supporting independent multi-channel processing—such as crossover, equalization, delay, and limiting—offering flexible configuration for diverse loudspeaker system requirements.
