Microtech Gefell M910

The M 910 condenser microphone has been developed for recordings of instrumental and vocal soloists in the professional market.  lts well balanced frequency response in the free-field as well as in the diffuse-field and the appropriate distinct characteristics ensure clean and colorless recordings of any sound sources with good selectivity.

lt is recommenced that the M 910 be used by soloists because it shows a specially optimized frequency response for this kind application.  A distance of less than 8 to 12 inches, which is recommended as minimum distance between lips and microphone, causes a coloration with an emphasis of lower frequencies, the proximity effect.

An acoustic filter integrated in the protective basket reduces the pop sensitivity. The direction of maximum sensitivity is axial (i.e. endwise to the microphone). This fact and the ergonomic design make this microphone the right choice for live performance of soloists.

Following the modern trend of technique the transducer is equipped with a gold plated polyester membrane.  The newly developed transformerless impedance transducer, having a balanced output stage, guarantees a high output capability and low intrinsic noise. Together, with the good qualities of the microphone capsule, a high brilliance of the live performance is reached. A 10 dB attenuator is installed to reduce the sensitivity of the microphone when placed near extremely loud sound sources.  And a low frequency roll-oft switch will reduce the proximity effect when dose miking. The two switches are sunk placed in the middle of the amplifier.
At the lower end of the amplifier the microphone is equipped with a 3-pin XLR connector fitting to the microphone cable C 70. These microphones use 48 volt phantom powering according to the international standards DIN 45596 and IEC 268-15.
