Sennheiser MKH 70 3149 Leaflet

Cat. No. 003149 

General Description

The MKH 70 is a lightweight long gun microphone. Its excellent directivity 
is particularly suited to applications  undertaken  in  difficult conditions, 
such as high background noise and distance microphone positioning. Its 
frequency-independent directivity prevents sound colouration from off-
axis sound sources.
