FBT MDA 4500 Description

The FBT MDA 4500 is part of the MDA4000 Series, designed to meet the needs of small to mid-sized audio installations with high flexibility and advanced control features. Capable of delivering up to 2000W of power across 4 channels, this amplifier handles both low-impedance and high-impedance speaker loads, making it ideal for distributed systems and multi-zone applications. With onboard DSP, a full 4x4 matrix, and an intuitive browser-based interface, users can manage routing, tuning, and monitoring directly from a smartphone, tablet, or PC—no dedicated app required. The MDA 4500 includes both wireless access point and wired LAN connectivity, offering installers remote configuration capabilities and simplified troubleshooting. Audio performance is optimized with ultra-low distortion, flat frequency response, and an excellent signal-to-noise ratio. Designed with reliability in mind, it features comprehensive protection circuits and dynamically controlled forced-air cooling for continuous operation in demanding environments.
