MIR 260 E

Thương hiệu: MARANI
| |


MIR-E series is a more cost-effective Audio processor newly created by MARANI Pro Audio for market demand.It has the basic performance comparable to MIR-A series, excellent background noise as low as -91dBu, combined with high dynamic range and powerful internal DSP calculation.So that it can cover a wider range of audio usage scenarios.  The series comes in four models:MIR260E(2 in 6 out)、MIR360E(3 in 6 out)、MIR440E(4 in 4 out)、MIR480E(4 in 8 out0.)

In addition to conventional audio processing, MIR-E series is also equipped with MIR (Marani Impulse Response) linear phase frequency pision filter.MIR has the filter shape of traditional IIR filter (Linkwitz-Riley 24+48/oct), but does not generate any phase shift.The resulting delay is about 50% of the FIR filter, which makes split-point phases easier to engage, and produces lower delay. Everything MARANI offers is for a better sound.

The design of dual RMS compressors can provide a better protection mechanism for the sound amplification system while using RMS compressors to control signal dynamics or shape sound intensity.

1.   The frequency response of the whole machine remains flat at 20-20kHz, the background noise is as low as excellent -91dBu, and the maximum input level reaches +20dBu.

2.   Full matrix mixing, any input channel can be sent to the output channel, and adjacent output channels can also be superimposed to the physical output.

3.   Each input and output channel is equipped with RMS compressor, which can control the signal dynamics in the input channel or be used to shape the sound intensity.   The output end can do RMS thermal power protection according to the RMS power value of the speaker unit.

4.   New MIR linear phase pider filter: MIR linear phase pider filter is a new frequency pider filter, it has the shape of the classical filter (LR24/48), without any phase distortion, so that the phase curve remains flat.

5.   The machine is equipped with standard network port, which is connected by tcp/ip local area network (LAN).   The PC automatically prompts that the device has been found and avoids USB/RS485 online due to the persity of Windows series and hardware, there are various driver and connection problems.   At the same time, wireless router can be used to achieve wireless online, providing more efficient and stable device control.

6.   New group setting, can control 32 processors at the same time, can unify the control of gain,&silence, etc, increase the convenience of multi-machine debugging.

7.   The input channel is configured with a dynamic loudness riser, which can effectively improve the listening sensation.
