MIURA 604I is a compact 1U, 4-channel Class D amplifier developed for installation applications requiring efficiency, flexibility, and low-profile integration. It delivers 4×150 W at 4–16 Ohm or 2×300 W at 70/100V in bridge mode, supporting both low-impedance and high-impedance systems with full asymmetric loading. Dante audio streaming (4 channels), TCP/IP network control (AES70), and AES3 digital audio I/O with link are all integrated, enabling complete system configuration via INFINITO software. The unit features a universal SMPS with Power Factor Correction, an Auto-Standby/Wake function, and a front OLED display for onboard control. Connections include Euroblock I/O, EtherCON ports, 8-channel GPIO, and an IEC 20A power inlet, ensuring safe installation and professional-grade integration.
