MKH 40 P 48  
Microphones | RF Symmetrical Capsule  
Condenser Microphone  
Cat. No. 002645  
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.
