DPA480D DPA Digital Audio Processor

High-Resolution Tuning + Professional Phase/Frequency Response Optimization: 96kHz/24-bit high sampling rate, with 15-band input and 10-band output PEQ adjustable, paired with various filter types including all-pass and high/low-pass; built-in FIR filters directly correct phase and frequency response issues for more precise sound restoration.

Intelligent Dynamic Adjustment + Precise Delay Control: Features a Dynamic Equalizer (DEQ) for automatic audio band optimization; input/output supports 2000ms delay adjustment to meet sound synchronization needs across diverse scenarios.

Multi-terminal Collaborative Control + DANTE Network Expansion: Equipped with 4 DANTE ports, supporting USB/RS232/TCP/IP multi-terminal control; enables networked configuration and remote monitoring of multiple devices, suitable for large-scale audio systems.

Features:

1. 96kHz 24-bit sampling rate, 15-band input PEQ, 10-band output PEQ, high/low pass filters;

2. Finite Impulse Response (FIR) filter with direct phase and frequency response correction via FIR Designer;

3. All-pass filter, 3 distinct characteristics: high/low pass, phase, band pass, notch filters;

4. Dynamic Equalizer (DEQ);

5. 2000ms input/output delay;

6. USB plug-and-play software, supports RS232 central control, TCP/IP wired and wireless control;

7. Multi-unit network integration and remote monitoring;

8. 4-channel DANTE.
