FBT MDA 4800 — 4-Channel Class D DSP Install Amplifier
MDA 4800 Overview
The FBT MDA 4800 is a compact, energy-efficient 2U rack-mount amplifier engineered for professional fixed installations. It operates in LO-Z mode delivering 4 channels x 750W at 4Ω or switches to HI-Z mode for 2 channels x 1500W at 100V, covering a wide range of distributed audio system requirements. A built-in DSP with browser-based access via integrated WiFi simplifies commissioning and ongoing system management without dedicated software installation. This amplifier is well suited for system integrators, install engineers, and AV contractors working in venues, houses of worship, commercial facilities, and similar fixed-install environments.
Preloaded FBT speaker presets streamline system alignment, while S/PDIF I/O and GPIO expand connectivity and control options for integration into broader system architectures.
