Sennheiser MKH40 Condenser Microphone

The 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.
