The Gefell M297 is a wide cardioid condenser microphone with a -10 dB attenuation switch, and a sensitivity reduction switch for low frequencies.
Studio Condenser Microphone Wide Cardioid
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.
