MIR480I

The MIR-F/I Series is the pinnacle of professional audio processing technology. Designed for professional Sound and System Engineers, these processors feature advanced capabilities such as Dynamic EQ (DEQ) and Auto EQ (AEQ). With up to 27 bands of parametric equalizers, the MIR-F/I Series allows extensive customization to meet the unique needs of any audio environment. The 8 channels Dynamic EQ processing module incorporates a sophisticated 5-band dynamic equalization system, featuring High/Low Shelving filters and three parametric filters. The DEQ supports four operational modes: Boost/Cut Above/Below Threshold, covering the entire audible spectrum from 20 Hz to 20 kHz. Each parametric filter offers three Q-factor modes for precise adjustments. MARANI’s Auto EQ simplifies system calibration with a proprietary algorithm that allows for one-touch measurement of impulse response. This innovative feature generates precise FIR coefficients and PEQ parameters automatically, enhancing efficiency in achieving optimal sound quality. Additionally, the inclusion of Dante protocol ensures seamless connectivity for modern audio networks. Elevate your audio performance with the MIR-F/I Series, where cutting-edge technology meets Italian engineering, transforming your listening experience with precision and unparalleled sonic intelligence.
