M 221

Product catalog summary

Overview: The M 221 is a studio condenser microphone designed by Microtech Gefell, featuring a small diaphragm capsule with a metal diaphragm and pressure transducer. It is transformerless and supports phantom powering at 48 V.

Applications: The M 221 is suitable for various recording scenarios, including main microphone use for capturing room acoustics, spot microphone for close instrument recording, and multichannel arrangements like AB stereophony or decca tree. It excels in environments with extreme transients and can operate in challenging climate conditions with the optional humidity adaptor TA 202.

Acoustical Specifications: The microphone features an omni-directional polar pattern with a frequency response from 20 Hz to 20 kHz (± 2 dB). It includes free field equalization and a pressure transducer capsule, ensuring stable transmission properties.

Electrical Specifications: The M 221 has a transformerless circuit design, supporting sound pressures from 15 dB(A) to 136 dB with a maximum of 0.5% THD. It uses a standard 3-pin XLR-male plug for connection and requires an external 48 V phantom supply.

Mechanical Specifications: The microphone consists of a capsule and preamplifier, both with a diameter of 12.7 mm, extending to 21 mm at the connection side. The total length is 170.4 mm, and it weighs 123 g, allowing for versatile mounting options.

Delivery and Accessories: The M 221 is delivered with a microphone holder and spherical corpuses in a wooden case. Optional accessories include a windscreen, elastic suspension, turnable microphone holder, and connection cable.

Technical Specifications: Key specifications include a sensitivity of 50 mV/Pa at 1 kHz, output impedance of 100 Ω, noise level of 15 dB(A), signal-to-noise ratio of 79 dB, and a dynamic range of 121 dB.

STUDIO CONDENSER MICROPHONE M 221 with omni directional pattern 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. APPLICATION 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...

ELEKCTRICAL SPECIFICATIONS The transformerless circuit design of the electronic impedance converter with symmetrical output facilitates an output capability for sound pressures from15 dB(A) up to 136 dB with a maximum of 0,5 % THD (total harmonic distortion). The microphone is connected by a standard 3-pin XLR-male plug with gold-plated pins which realizes the powering by an external 48 V phantom supply according to IEC 61938 with a current consumption of 6 mA. MECHANICAL SPECIFICATIONS The M 221 consists of a microphone capsule and a microphone preamplifier as independent mechanic parts which...
