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.
Legacy or CORE by DPA – the choice is yours
The legacy d:fine™ 4066 has always been, and still is, one of the most clear, consistent and robust miniature microphones you can find on the market. It’s known for working across a wide dynamic range as well as exhibiting low distortion across all SPLs. If you need to squeeze a little more performance out of your mics, choose CORE. The d:fine™ CORE 4066 gets a 14 dB increase in dynamic range and from a whisper to a scream reduces the general distortion:
Total harmonic distortion: < 1% THD up to 137 dB SPL peak
Dynamic range: Typ. 111 dB
All CORE by DPA technology microphones are IP58 certified. This durability is achieved through a number of defense mechanisms:
• Water-repellant nano-coating of the cover and housing
• Hermetic sealing of the sensitive amplifier at the core of the mic
• Dual gold plating of the diaphragm
The d:fine™ CORE 4066 Omnidirectional Headset Microphone is in beige, black and brown with either MicroDot, 3-pin LEMO, TA4F Mini-XLR or Mini-Jack termination.
