Sennheiser MKH 20-P48 Omnidirectional RF Condenser Mic

The MKH 20-P48 is usually used as a main microphone for orchestras and solo instruments, and picks up the natural acoustics of the room, though it does have a much wider range of applications as omnidirectional microphones do not suffer from ‘proximity effect’.
