The D40 professional instrumental microphone with its solid all-metal body will stand up to the hardships of night-after-night onstage use with a smile. Its patented Varimotion diaphragm uses a unique laminated material to damp high resonance peaks, leading to a quantum leap in audio performance. The transducer is protected by a sturdy wire-mesh cap and can take extremely high sound pressure levels with ease. An integrated stand adapter in combination with the included H440 mounting bracket makes the D40 a highly versatile tool for use on drums, percussion, wind instruments and guitar amps.
