MIR Flagship (FI Series)

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 Ringquitzrelli/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.

1. The whole machine operates at a sampling rate of 96KHz, and the frequency response remains flat between 20Hz-45kHz.
2. Complete 8 input processing channels +8 output processing channels, maximum simultaneously 12 output channels (analog +Dante)
3.Each output is equipped with a Dynamic EQ (DEQ, Dynamic Equalization) designed and developed exclusively by MARANI® for dynamic compensation/attenuation management of the system. Each DEQ provides 5 segments of filters including: 3 peak filters and low/high Scheffer filters
4. Innovative full matrix mixing, input channels are sent to plug-in nodes in any proportion, different plug-in nodes can also be mixed into one or more output channels, or even two adjacent output channels can be mix into the physical output channel.
5. The input channel is equipped with dynamic loudness filter and automatic RMS compressor, which can effectively control the signal dynamics of the input channel. The new design has a hard limiter with very low distortion, which can prevent the burst large dynamic signal from damaging the speaker unit and effectively guarantee the safety of the system.
6. AutoEQ automatic balancing algorithm, can run at the input/plug-in/output position, one-click measurement of impulse response, according to manually set or automatically calculated flat frequency response. You can use pure IIR/ pure FIR/IIR+FIR mixed modes to completely solve the phase problem.
7. Up to 4096Taps FIR filter.
8. New MIR linear phase crossover filter: The MIR linear phase crossover filter is a brand new frequency crossover filter, can use any of the classical filter shape, without any phase distortion, so that the phase curve remains original.
9. A network interface is configured to connect to the PC directly through a network cable. By default, DHCP automatically obtains an IP address.
10. New group Settings, can control up to 128 processors at the same time, can be unified control gain, mute, PEQ and polarity, increase the convenience of multi-machine turning.
11. Advanced Plugins, including 96kHz extended bandwidth FIR filter and Dynamic EQ..etc.
