FBT MIURA 604I Power Amplifier

FBT MIURA 604I Power Amplifier

FBT MIURA 604I is an 4-channel Class D power amplifier with integrated DSP.

It drives low-impedance passive loudspeakers or 70 / 100 V lines. The chassis fits a standard 19-inch equipment rack.

Asymmetric loading enables power distribution according to channel demand. The switch-mode supply with PFC manages mains current and supports sustained peak output.

INFINITO for Windows provides DSP control and signal routing, groups and scenes, sensor and level monitoring, global mute and device firmware updates.

Main Features

• Dante: 4 inputs and 4 outputs, 24-bit audio at 48–96 kHz.
• 2 × EtherCON network ports support TCP/IP, AES70 control and daisy-chain connections.
• OLED display with push encoder: channel levels, sources, MUTE, speaker presets, SNAPSHOT, IP settings and menu lock.
• 4 balanced analogue inputs, 4 amplifier outputs and AES3 with LINK use screw-terminal Euroblock connectors.
• Separate RJ45 IN/OUT ports relay the four analogue channels to another amplifier. These are distinct from the Ethernet ports.
• 8 GPIO channels can act as analogue or digital inputs or digital outputs; fault relay contacts are provided.
• Auto-Standby and Auto-Wake reduce idle use when enabled and resume operation when an input signal returns.

Cooling uses a variable-speed fan with front-to-rear airflow. Allow at least 60 × 330 mm behind the amplifier and 100 mm above the rack. Secure the rear in mobile racks.

SE operates individual channels. Configure BTL in INFINITO on a Windows PC before connecting the loudspeaker load; the minimum bridge load is 8 Ω.
