The DSP in the SuperCMIT detects a discrete sound from different directions and whether the sound has a discrete, permanent direction. The algorithm also detects a diffuse sound from all directions. This information is used to suppress diffuse sound and to focus on discrete sound.

This allows the range of the microphone to be increased significantly – without the typical artifacts in sound color. The SuperCMIT is the world’s first microphone that combines high directivity with high sound quality.

The SuperCMIT 2 U has three buttons that enable/disable the filters and presets of the microphone. The two filters are identical to those of the analog tube CMIT 5 U: high-frequency emphasis (+5 dB at 10 kHz) compensates for the attenuation of windshields; the steep low-cut (18 dB/octave from 80 Hz) suppresses low-frequency wind and boom noises.

While the unprocessed CMIT signal is always at the output on channel 2, channel 1 is the output of the SuperCMIT. A preset button determines its directivity. Two positions are possible:

Preset 1: Moderate increase of the directivity and attenuation of the diffuse sound by 11dB (5dB more than the SCHOEPS CMIT 5U or channel 2 of the SuperCMIT)

Preset 2: The attenuation of the diffuse sound is 15 dB. This position is reserved for special applications – in some cases artifacts are possible.

The gain can be raised by +30 dB by double-clicking on all three buttons.

For the SuperCMIT, two power supplies are available, which are needed if the recording device doesn’t support AES42.

– PSD 2U: digital 10V phantom power, AES3 output

– MiniDA42: digital 10V phantom power, AES3 output, 2 analog outputs.
