The DPA SMK4081 Clip-On Supercardioid Microphones is a high quality directional condenser microphone primarily intended to use for ultra-low profile, discreet recordings in the field or as all-round microphone for instrument miking.
Each 4081 is a complete, integrated system combining microphone, windscreen, shock mount and cable management system.
The main features of the DPA SMK4081 Clip-On Supercardioid Microphones include:
