The DPA 4066 Omnidirectional Headset Microphone is the staple choice for headset microphones in theatre and broadcast, well loved for its robust, well-designed frame and excellent sound thanks to its capsule's Core technology.
The headset construction is unique. You can detach the mic boom from the headset mount to switch it to either the left or right side and then reattach it. Humidity, often an issue in theatrical applications, is not a problem. This microphone is constructed with a double-vent protection system and a drop stopper on the microphone boom. Also, the materials inside the mic are water resistant. These design elements make it very difficult for the microphone to fail due to humidity.
The microphone’s sensitivity is 6 mV/Pa. This matches the level of the human voice to the general input sensitivity of most wireless transmitters. If powered correctly, the microphone will be able to handle very high sound pressure levels up to 144 dB SPL before clipping occurs.
The 4066 CORE Omnidirectional Headset Microphone is in beige, black and brown with either MicroDot, 3-pin LEMO, TA4F Mini-XLR or Mini-Jack termination.
