FU-PRODP48 – Digital Audio Signal Processor
Advanced DSP control for live sound, studio systems, and installed audio environments.



Professional Digital Audio Signal Processor for Precision System Control
The FU-PRODP48 digital audio signal processor is engineered for professional live and studio sound applications.Designed for live sound, installed systems, broadcast trucks, and studio environments, this unit delivers powerful DSP processing with exceptional signal integrity. Built around the ADSP-21571 chip and featuring 48-bit internal resolution, the DP-48 sets a new benchmark for modern digital audio signal processor performance.
With support for multiple analog inputs and seamless connectivity via USB or internal network control, the FU-PRODP48 adapts effortlessly to complex system configurations.
Powered by the ADI Five Series DSP platform, this digital audio signal processor offers 50% more FIR and EQ processing capacity than previous generations. Input channels include 5 bands of dynamic EQ (DEQ), 31 bands of graphic EQ (GEQ), and 15 bands of parametric EQ (PEQ), providing unmatched tonal control.
Output channels feature 15 bands of PEQ, FIR filters, adjustable voltage limiters, and noise gates for full loudspeaker management. With up to 750ms delay, 48dB maximum gain, and +20dBu output level, the processor ensures optimal alignment and system protection in demanding applications.
The AD1955 DAC supports 24-bit/192kHz decoding with a 120dB signal-to-noise ratio, delivering pristine audio reproduction across all frequencies.
Imagine deploying a system in a feedback-prone venue and solving problematic frequencies in seconds. The FU-PRODP48 digital audio signal processor allows surgical EQ cuts at 250Hz, 500Hz, or 1kHz without sacrificing tonal warmth. Whether calibrating monitor mixes, integrating subwoofers, or correcting room modes around 63Hz and 125Hz, this processor offers precision that eliminates guesswork.
Its PC software includes a built-in signal generator for speaker calibration, enabling on-site optimization without external tools. Thirty factory presets accelerate deployment, while custom user presets allow full system personalization.
This is not just processing — it is total system command.
Upgrade your workflow with the FU-PRODP48 digital audio signal processor and experience unmatched control, transparency, and reliability. Designed for sound engineers, rental companies, studios, and broadcast professionals, it delivers advanced DSP performance at an accessible investment level.
Take control of your system. Optimize every frequency. Protect every speaker.

Professional Applications
- Feedback Elimination in Live Sound – Identify problematic frequencies (typically 250, 500, 1kHz in venues) and apply narrow-Q cuts to eliminate ringing while preserving tone.
- Monitor Mix Equalization – Shape individual monitor sends for instruments/vocals with surgical precision, preventing buildup of competing frequencies
- System Room EQ – Correct acoustic room modes (low-frequency modes near 63, 125 Hz common in small venues) improving clarity and impact.
- House of Worship Sound SystemTone Shaping for Non-FEUR Loudspeakers – When using third-party speakers, parametric EQ enables frequency response optimization without external crossovers.
