The DPA d:screet™ 4080 Miniature Directional lavalier microphone has been designed for use in broadcast studios where the noise floor is slightly higher and would not offer the ideal ambient situation.
The 4080’s directional characteristics – its cardioid polar pattern – enable better separation between of the source and the background noise. The 4080 lavalier mic comes with its own windshield and suspension system fitted to a flexible ball joint clip so it can be mounted either on the left or the right. To highlight speech intelligibility the frequency response has a gentle 4dB boost between 4 and 6Khz and a -5dB filter at 100Hz to further improve clarity.
The DPA d:screet 4080 lav mic is terminated to a microdot connector and using the DPA adaptor system the microphone can be interfaced to virtually any available wireless microphone system or hard wired directly using the DPA XLR adapter (DAD6001-BC).
