MKH 40 P 48

Microphones | RF Symmetrical Capsule

Condenser Microphone

General Description

The cardioid MKH 40 has a large number of applications, for example as
a main microphone, especially in lightly reverberant or acoustically less
perfect rooms, with instrumental groups or for speech applications. Its
wide-angled, neutral directional characteristics and high level of reverse
attenuation ensure an exceptionally balanced sound.
