With a soft rubber necklace, the d:screet Necklace Microphone is comfortable to wear and can be fitted easily by the subject, requiring no clips or ‘fiddly bits’ to get to grips with. Simply fit it over the head of the subject and you’re ready to go. There are two lengths of necklace – 47cm and 53cm.
DPA’s 4061 omni capsule provides excellent gain before feedback and with the necklace fitting will always provide consistent output. The microphone capsule extends at a slight upward angle to bring it closer to the wearer’s mouth and as it is an omni capsule, the d:screet 4061 Necklace Mic’s capsule does not suffer from any proximity effect.
Available in three colours, black, brown and white, DPA’s d:screet™ Necklace Microphone is, as the name depicts, discreet, and can be blended with clothing for minimal visual impact. The DPA microdot adapter system means that the DPA Necklace Mic will adapt to fit with all pro wireless systems without a hitch.
