Product Description

To better pick up the subject’s voice, it has a high pass filter at 100Hz to reduce rumble and increase headroom as well as being fitted with a high frequency boost to improve the mic’s response to speech. While not a directional microphone, the d:screet 4071’s frequency response has been tailored to focus in on the wearer’s voice, rendering any spill as natural-sounding as possible.

The 4071 comes in black, beige and white and using the DPA adaptor system the microphone can be interfaced to virtually all available wireless microphone systems.

The variety of accessories include DUA0571 Windjammer, DUA0572 miniature protective mesh, lavalier clips, windscreens as well as complete accessory kits for Film and ENG work.
