Marani MIR480I Flagship MIR 4 IN 8 OUT Audio System Processor Speaker Management Marani MIR-480I DLMS

Harga Untuk 1 Unit

MIR480I uses powerful MARANI DSP in signal processing. DSP and AD/DA converter both run at 96KHz sampling rate. Complete processing functions provide a complete speaker crossover solution.
From the input gain/delay/noise gate /EQ/ compression /FIR to the output gain/delay/polarity/


OVERVIEWFEATURESSPECIFICATIONSDOWNLOADS1. The whole machine operates at a sampling rate of 96KHz, and the frequency response remains flat between 20Hz-45kHz.
2. Complete 4 input processing channels +8 output processing channels, which can realize redundant switching of overlapping signals through double matrix routing
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.
