EQ-215 Graphic Equalizer
MIR480A is a digital audio processor newly designed by Marani. It has extremely low noise floor, high dynamic range and powerful internal DSP to cover most of the usage scenarios. Whether in meeting rooms , theaters , touring performances, or even large-scale tours, you can use the A series processors. Advanced circuit design and original DSP algorithm are the core of pure and high-quality sound. In the signal processing part of MIR480A, inside powerful MARANI DSP, DSP and AD/DA converters are running at 96KHz sampling rate, complete processing functions provide a complete speaker crossover solution. From input gain/delay/noise gate/EQ/compression/FIR ，tooutputgain/delay/polarity/frequency division/FIR/EQ/compression/compression, there are up to 16 types of parametric equalizer (PEQ) The filter type can be selected. The output crossover filter has the classic Linkwitz-Riley /Bessel/Butterworth, and there are also NXF horntype filters and FIR filters with a slope of up to 120dB per octave. The newly added MIR linear phase frequency divider filter can make the phase of the crossover point easier to join and produce a lower delay. Everything we provide is for better sound. Added DSP plug-in, providing 96kHz FIR filter/highorder signal generator/RTA real-time spectrum analyzer, etc. The newly designed Hard Limiter (Hard Limiter) allows a constant rate limit on signals exceeding the threshold at any threshold to better protect the speaker unit. Each input and output channel provides a maximum 512-tap FIR filter, which can be customized by third-partysoftwaretogeneratetheFIR convolution you need. It can be used for speaker presets to improve the phase response and control the directivity according to requirements. The newly added MIR linear phase divider filter has the filter shape of the traditional IIR filter (Linkwitz-Riley 24+48/oct), but does not produce any phase shift, and the resulting delay is about 50% of the FIR filter.
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.
The Mir-F family of digital processors are Marani's new flagship system processors, including the MIR480I and MIR880F.The hardware adopts top AD/DA chips with excellent -96dBu background noise. It also has analog, digital AES/EBU, and Dante signal access capabilities, and has automatic switching function. Any signal can be set as the highest priority. As the core processor of the system, it has the redundancy and backup characteristics, and is suitable for government projects, high-end clubs, large mobile performances, theaters, radio and television and other places with higher requirements for signal processing. From the input gain/delay/noise gate /EQ/ compression /FIR to the output gain/delay/polarity /crossover/FIR/EQ/ compression/peak limiter, the parametric equalizer (PEQ) has up to 16 filter types to choose from. The output crossover filter has the classic Linkwitz-Riley/Bessel/Butterworth, The NXF（Notched X-over Filter） and FIR filter with slope up to 120dB per octave are also available. The new MIR linear phase crossover filter makes it easier to engage the phase of the crossover point and produces lower latency. Everything we offer is for better sound. With the addition of DSP plug-in, traditional processor architecture is usually fixed and unadjustable. Marani innovatively introduces the concept of plug-in, and uses powerful co-processor to complete dynamic processing that traditional processor is difficult to complete, such as dynamic balancing, linear phase multi-segment compression, feedback suppression and other functions. This feature is an open architecture, and the type and number of plug-ins will be updated from time to time. The new design of Hard Limiter allows constant rate limiting of signals exceeding the threshold at any threshold, better protecting the speaker unit. Each input/output channel provides a filter with a maximum of 512 tap FIR. You can use the built-in AutoEQ plus an external ASIO sound card to measure pulse and generate FIR coefficient or use third-party software to generate FIR coefficient as you need. For speaker preset, phase response can be improved and directivity can be controlled as required. The new MIR linear phase crossover has the type and shape of the traditional IIR filter, but does not produce any phase distortion, and the delay generated is about 50% of the FIR filter.
