The Studio Pro M2 can be used as a main microphone for orchestra recordings, as a spot mic for single instruments, and as a vocal microphone for all types of music and speech. The large gold-plated diaphragm capsule has a very smooth frequency response for all polar patterns. The microphone can be used very close to a sound source without the sound becoming unnaturally harsh. By means of a switchable high pass filter, interference through subsonic and low frequencies is reduced remarkably. As such, this switch cuts the low-frequency response reducing the proximity effect.
