The M 294 extends the SMS 2000, Studio Microphone System. The proved microphone capsules M 70 and M 94 form a unit with the modified microphone amplifier MV 200.
These microphones are designed for a universal applications in professional recording and sound reinforcement and meet the requirements of modern technics.
The newly developed, transformerless circuit design substitutes the previous transformer for a symmetrical output stage. Its intrinsic noise and remarkably output capability emphasize the advantages of the microphone capsules M 70 and M 94. Microphone capsules with an extremly thin metal diaphragm enable brilliant sound transmission.
The direction of maximum sensitivity is axial. The studio microphones are equipped with a wide range of accessories for many microphone mounting methods.
lt is possible to activate a 10 dB-attenuator pad for handling very high sound pressure levels. A sensitivity reduction for low frequencies can be utilized to suppress the proximity effect. The two switches are into the middle of the preamplifiers.
The microphone is equipped with a standard 3-pin XLR connector fitting to a microphone cable, e.g. C70. The operation voltage is provided by 48 V phantom powering, according to the international standards DIN 45596 and IEC 268-15.
They are available in a satin nickel or a black matt finish.
Both condenser microphone capsules are pressure gradient transducer. The converter elements contain a nickel diaphragm with a thickness of less than 1 µm. The back-plate electrodes are Teflon-coated to increase operational reliability.
M294 The desired presence boost of ca. 5dB in the 8kHz range gives this microphone its special clarity.
lt is recommended to use a popscreen and to switch on the microphone bass rolI-off for closerange applications.A windscreen can be utilized to enhance life-like recording.
