FBT MIURA 604I — Compact 1U DSP Install Power Amplifier
MIURA 604I Overview
The FBT MIURA 604I is a 1U, 4-channel Class D power amplifier engineered for permanent installation environments where efficiency, flexibility, and a low-profile form factor are essential. It delivers 4×150W into 4–16 Ohm for standard low-impedance configurations, and switches to 2×300W in bridge mode for 70V and 100V distributed audio systems. Full asymmetric loading support allows mixed system topologies within a single unit, making it well suited for system integrators, houses of worship, corporate AV installations, and hospitality venues. The MIURA 604I is designed for integrators who need a reliable, space-efficient amplifier platform that adapts to diverse installation requirements without sacrificing output capability.
Its compact 1U chassis simplifies rack density planning, while Class D efficiency reduces heat load and power consumption in equipment rooms and low-ventilation enclosures.
