The AD48F is a high-end professional FIR speaker management processor designed for advanced PA system tuning and precision audio control. Featuring 96kHz sampling frequency, a 64-bit DSP core, and 32-bit A/D and D/A conversion, the AD48F delivers exceptional audio accuracy and low latency. It supports multiple I/O configurations and flexible routing, making it suitable for complex sound reinforcement systems. With independent FIR processing on each output, advanced EQ, delay, dynamics control, and comprehensive system security, the AD48F is an ideal DSP solution for live sound, touring systems, and permanent professional audio installations.
1. High-Resolution 96kHz FIR DSP Architecture
The AD48F is built on a powerful 64-bit DSP processor operating at 96kHz, combined with high-quality 32-bit A/D and D/A conversion. This architecture ensures ultra-precise signal processing, improved phase accuracy, and superior sound clarity, making it ideal for professional loudspeaker management and FIR-based system optimization.
2. Flexible Multi-Configuration Input / Output Design
The processor supports multiple I/O configurations, including 2×4, 2×6, 2×8, 3×6, 4×6, and 4×8. Flexible crossover and matrix routing allow high-pass and low-pass filters to be set from 20Hz to 20kHz, enabling precise system design for full-range speakers, subwoofers, and multi-way PA systems.
3. Independent FIR Processing on Each Output Channel
Each output channel includes an independent FIR engine supporting up to 1024-order FIR filters with parameter import and backward compatibility. Channel names can be edited and stored individually, allowing engineers to implement accurate phase correction, linear-phase crossover, and custom loudspeaker tuning.
4. Advanced EQ, DEQ and Dynamic Control
Every input channel provides 12 bands of fully parametric EQ, adjustable up to ±20 dB, while each output includes 15 parametric EQ bands. The AD48F also integrates dynamic EQ (DEQ), noise gate, compression, and limiter functions, offering complete tonal shaping and system protection for professional sound reinforcement.
5. Precision Delay, Phase and Alignment Control
Each input and output channel features adjustable delay, polarity, and mute control with a maximum delay of 1000 ms. Delay units can be displayed in milliseconds, meters, or feet, with coarse and fine adjustment modes for accurate speaker alignment in large venues and distributed audio systems.
6. Comprehensive Connectivity and Network Control
The AD48F provides USB 2.0, USB 3.0, RS485, and TCP/IP interfaces for system integration. RS485 supports control of up to 250 devices over distances exceeding 1500 meters, enabling centralized management of large-scale audio systems and remote control applications.
7. User-Friendly Interface and System Security
A 2×24 blue backlit LCD and multi-segment LED level meters provide clear real-time monitoring of input and output signals. The processor supports up to 60 user presets, password-protected parameter locking, and multi-level access control to ensure system stability and data security.
8. Built-In Signal Generator and Diagnostic Tools
The integrated signal generator allows system self-testing, calibration, and on-site debugging without external equipment. This feature significantly improves commissioning efficiency for professional sound installations and touring setups.
