Microtech Gefell M 221 Omni Condenser Studio Microphone ½ Nickel Capsule

Studio Microphone M 221

The condenser microphone M 221 unifies universal small diaphragm capsule technology with a metal diaphragm and a modular preamplifier. The use of a certificated measurement capsule combined with a preamplifier with 48 V phantom powering reaches a constant magnitude and phase response and transmission properties which are long-term stable.

Because of the small capsule dimensions the M 221 is ideally suited for applications where a low interference with the sound field is demanded. It is usable as a main microphone for recordings which should include a certain amount of the room response. As well the M 221 is suited as a spot microphone for recording instruments very close where the low frequencies should be transmitted in detail and original. Moreover it can be used for multichannel main microphone arrangements like AB stereophony or decca tree. For these applications the microphone is ideal because of its precise and long-time stable transmission properties. The M 221 has an excellent transient response because of the pressure transducer capsule and is really suitable to record instruments with extreme transients. With the both different sized spherical corpuses a high frequency accentuation can be produced in an acoustical way to increase the presence and to compensate the high frequency roll-off in the diffuse sound field. The M 221 can operate also in unfavorable climate conditions especially referring the temperature and air humidity for which the accessory humidity adaptor TA 202 is purchasable.

The use of the M 221 with the acoustical equalization ball KA 3 effects a frequency response accentuation which begins at approximately 1 kHz and goes constant at 3 dB from approximately 4 kHz up to 12 kHz. With the acoustical equalization ball KA 4 the accentuation of the high frequencies starts also at approximately 1 kHz and goes constant at 3 dB between 3 kHz and 12 kHz.
