Gefell M930 Ts

The studio microphone M 930 Ts unifies approved large diaphragm capsule technology with anoptimized output transformer and a new developed circuit design.

That attains a signal transmission with negligible distortion combined with a lower low frequency response, a very low noise floor and a high sound pressure level even at high external load.

Because of the compact dimensions of the M 930 Ts it is ideally suited for applications where an optical inconspicuousness and an absolute view to manuscripts and monitors is demanded. It can be placed on speaker desks in radio stations as well as for recordings of dialog pickups, audio books and in dubbing studios. Moreover it can be used as main microphone for recordings of solo instruments or vocals, as spot microphone for recording instrumental groups and for setting up multichannel main microphone arrangements. There are accessories for XY-, ORTF and INA 5 arrangements available. Because of the balanced low-impedance transformer output the M 930 Ts can be used for longer cable length with negligible distortion.

The pick-up pattern is perpendicular to the direction of the microphone axis (side addressed) and is marked by the model number and the polar pattern symbol. The company logo is at the reverse side of the microphone. A condenser microphone capsule with a diameter of 28 mm and a gold-plated polyester membrane is installed as sound transducer. The polar pattern is cardioid with a very high attenuation of rear sound incidence. The M 930 Ts has a constant frequency response with an accentuation of approximately 2,5 dB between 6 kHz and 12 kHz to raise the speech and high-frequency presence. The change of the low end frequency response caused by the proximity effect is well-balanced without a very strong overemphasis at small microphone distances

The newly optimized circuit topology of the impedance converter leads in combination with the specially designed output transformer to a very high transmission level range for sound pressure levels from 7 dB(A) to 144 dB with a maximum of 0,5% THD (total harmonic distortion). As a result, the M 930 Ts has a clean, distortion free sound over an extremely wide dynamic range. RFI susceptibility is very low. 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.

The capsule is mounted elastically in the compact microphone housing of the M 930 Ts with a diameter of 45 mm and a length of 130 mm for attenuating solid-borne sound and impulses. If a higher attenuation of such influences is required it can be achieved by elastic holders and suspensions which are available as accessories. The weight of the M 930 Ts is 273 g without any holder and suspension. That weight allows the use of the microphone with standard microphone arms, stand mountings and other holders as well as on a microphone tang without any problems.
