M Cube
From Microtech Gefell:
The M Cube is a 9-channel microphone system for time-delay based 3-dimensional recordings. The nine microphones are arranged in the shape of a cube with a length of approximately one metre each side. The positions of the microphones are adjustable – so the dimensions of the microphone arrangement can be adjusted to the dimensions of the room and the sound source. The mounting bars have distance markings, so that any setting can easily be repeated.
The M Cube is set up as a 5.0 array with another four microphones for height information. Five M 102 capacitor microphones are used for the lower plane and four M 221 capacitor microphones are used for the upper plane. All the microphones are omni-directional pressure microphones. Because of this, the frequency response is independent from the distance to the sound source and there is no proximity effect; sensitivity to wind noise is very low.
The use of certified WS1F- and WS2F- measurement microphone capsules, combined with a 48 V phantom powered pre-amplifier (that internally raises the capsule bias voltage to the required 200 V) reaches a constant magnitude and phase response according to the tight tolerances of DIN EN 61094-4 and with transmission properties that are long-term stable. Only the diameters of the capsules and the noise level of the M 102 and the M 221 are different, all other transmission properties and the construction of both microphones are identical.
