The Sennheiser MKH 40 Microphone is a pressure gradient condenser microphone designed for remote recording, sound reinforcement, instrument capturing, group and choir capturing and speech. The MKH 40's capsule features symmetrical transducer technology that ensures extremely low distortion, and its wide angle cardioid polar pattern provides balanced sound reproduction. Reverse attenuation ensures maximum rejection of off-axis sound, providing exceptional control of the captured ambiance. The MKH 40 features a low frequency roll-off switch, to minimize rumble and noise. Switchable pre-attenuation provides an additional 10dB of headroom, preventing distortion and overload caused by transient signals at close proximity.
