Product overview
The DPA 4066 CORE is an omnidirectional headset microphone with clean and transparent sound quality and lots of headroom, for years the chosen headset microphone of broadcasters and theatres and of many auditoriums and lecture halls, thanks to its pristine sound and durability.
Its sensitivity of 6 mV/Pa matches the level of the human voice to the general input sensitivity of most wireless transmitters. Powered correctly, the microphone handles very high sound pressure levels, up to 144 dB SPL peak.
The headset construction is unique: the boom can be detached from the headset mount, switched to the left or right side and reattached. Humidity, often an issue in theatrical applications, is not a problem: a Double Vent Protection System, a drop stopper on the boom and water-resistant materials inside the microphone make it very difficult for the microphone to fail due to humidity.
The 4066 CORE uses CORE by DPA technology and is offered with the MicroDot connector for use with DPA adapters, or terminated terminated in 3-pin LEMO, TA4F Mini-XLR or Mini-Jack, in black, brown or beige, and in Standard and Small sizes.
