DPA 4466-OC-R-C10 4466 CORE Omni Headset Microphone, Brown, TA4F Mini-XLR
The 4466 CORE Omnidirectional Headset Microphone combines DPA’s renowned 5 mm capsules with CORE by DPA technology and the Red Dot award-winning headset.
These are the most advanced headsets – secure, durable and flexible – for segments including: Theatre, Broadcast, House of Worship and Conferencing.
This omni mic offers clean and transparent sound quality with lots of headroom. 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. When powered correctly, the microphone will be able to handle very high sound pressure levels up to 134 dB SPL so users can both speak and sing into the mic with no hint of distortion. The max SPL handling is an impressive 144 dB.
Technically advanced mechanical headset mount construction
The one-size-fits-all Headset is the most advanced construction on the market. It ensures comfort, even during long-term wear, but does so without sacrificing security. Its form grips gently and snuggly around the head and is easily adjustable. The spring mechanisms that grip around the ears are gentle, yet firm enough for you to feel secure during your performance. The Headset can also be customized on site to suit innavidual performers for perfect fit. These characteristics are also the reason why it was awarded the prestigious Red Dot award in 2019.
One-size fits all, adjustable frame
The headset frame is made of stainless steel and treated with a Physical Vapor Deposition (PVD) coating that makes it extremely durable. It can tolerate high temperatures and is resilient against impact and abrasion. The frame is one-size fits all with a simple adjustment mechanism for quick and easy resizing. Anatomically correct, it fits snuggly and comfortably around the head thanks to its unique shape. The entire mic has a pleasant matte look due to the coating, making the entire headset look small and less obtrusive than other headset solutions. Furthermore, it adds nothing to the size of the microphone, as the PVD is extremely durable but at the same time extremely thin.
2-way adjustable boom
The boom can easily be adjusted so that it sits perfectly at the corner of the performer’s smile (the optimal placement of a headworn mic). Not only can the boom be extended / shortened, but it can also be pivoted up and down at a fixed point below the ear (no more bending the boom). An anti-rotating mechanism designed into the boom shape, prevents it from rotating. A sliding lock system ensures that the boom is locked into the desired position. The entire boom can be detached at a point below the ear and moved from the right to left side of the frame.
We have also added a service connector at the end of the boom pole so that the boom and cable can be replaced independently if needed. The service connector is well-protected by a plastic cover that slides over the gold-plated connectors.
PVD-treated mic
The beige and brown versions of this mic are treated with a surface that mimics the color of the boom and adds a very distinct expression of the entire headset.
