The M 930, M 940, M 950 studio condenser microphones combine modern large diaphragm capsule technology with the latest in semiconductor circuit topology. They are specifically designed to meet the needs of professional and semi-professional users who demand the highest performance.
The microphones are ideally suited for universal miking applications in broadcast and sound studios. Their very favorable pricing also makes them attractive for project studios. Applications include vocalists, announcers, dialog pickup and as spot microphones for recording guitars, keyboard, percussion, wind and string instruments.
The pick-up pattern is perpendicular to the direction of the microphone axis (side addressed). The model number and pick-up pattern symbol mark the front of the microphone.
The condenser capsules exhibits a smooth frequency response with a slight presence boost in the 7 to 11 kHz range. The polar response exhibits an exceptionally high degree of rejection for sounds impinging from the rear (cardioid) or sides (super-cardioid) of the microphone.
The electronic impedance converter uses a newly perfected circuit topology. This design reduces the noise floor to an extremely low level while also raising the maximum output capability. As a result, these microphones have a clean, distortion free sound over an extremely wide dynamic range. RFI susceptibility is very low.
The microphone capsule and electronics are elastically suspended inside the compact metal housing. This reduces the sensitivity to mechanical impact and structure born noise. The microphone stand holder MH 93.1 can be exchanged for an elastic suspension EH 93 to further attenuate noise in extreme situations.
The M 930, M 940, M 950 connect to the microphone cable with a standard 3-pin XLR plug. Powering must be provided by an external 48 V phantom supply according to DIN 45596 and IEC 268-15.
The microphones are finished in either a satin nickel or dark bronze color.
