The DSP in the SuperCMIT detects discrete sound from different directions and whether the sound has a discrete, permanent direction. The algorithm also detects 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 the attenuation of wind shields; 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.
