DP36 DP Digital Audio Processor

High-Precision Crossover Equalization + Professional Phase Optimization: 96kHz/24-bit sampling rate, 15-band input and 10-band output PEQ adjustable, paired with 48-stage high/low-pass crossover; built-in FIR filters and all-pass filters optimize speaker phase coupling and correct phase curves for high-fidelity sound reproduction.

Intelligent Dynamic Adjustment + Multi-Terminal Flexible Control: Equipped with Dynamic EQ for automatic compensation of audio frequency band deficiencies; supports USB plug-and-play, RS232 central control, TCP/IP LAN remote control, and wireless operation via Android app, enabling synchronized parameter adjustment across multiple devices.

Secure Parameter Management + Streamlined System Debugging: Supports independent channel parameter saving and copying with archive locking to prevent accidental changes. Customizable power-on settings automatically save current parameters or lock unique startup states, simplifying system maintenance.

Features:

1. 96kHz/24-bit sampling rate, 15-band input PEQ, 10-band adjustable output PEQ with high/low shelving and all-pass filters. Both inputs and outputs feature 48th-order high/low pass crossovers. Tuned parameters can be saved per channel and copied to other channels, enabling comprehensive audio system adjustments.

2. Allpass filter for adjusting phase coupling at crossover points between speakers or cabinets, resolving acoustic phase interference issues;

3. Finite Impulse Response (FIR) filter: Unlike traditional IIR filters, FIR filters offer greater stability. They enable EQ and crossover tuning without phase distortion and support phase correction. Phase curve parameters can be configured via third-party software, imported into the processor, and applied to achieve comprehensive acoustic phase optimization for the speaker system, delivering more accurate and clearer sound reproduction. Input configuration: 256-1024-order FIR filters; Output configuration: 256-512-order FIR filters. Additionally, 11 distinct window function filters are provided for application.

4. Dynamic EQ dynamically equalizes audio by boosting or attenuating specific frequency bands by 0-12dB when they reach a threshold. This compensates for system deficiencies (e.g., harsh mid/high frequencies or insufficient low frequencies) and enables automatic equalization for consistent performance in any situation.

5. USB driverless auto-connect software, additionally supporting RS232 central control and TCP/IP LAN remote control;

6. Mconsole unified management connects control devices via USB/RS232/TCPIP interfaces. The TCP/IP port enables powerful functions like LAN remote control, multi-device management, synchronized parameter settings, and joint parameter tuning;

7. Archive locking prevents accidental or intentional tampering with processor parameters, maintaining system stability while safeguarding speaker calibration settings. Archive support includes power-on configuration: automatically save all real-time calibration parameters or set unique power-on state parameters to meet diverse system maintenance needs;

8. Supports Android app TCON wireless control.
