The DPA Microphones 4466 CORE Omnidirectional Headset Microphone combines DPA’s renowned 5 mm capsules with CORE by DPA technology and the Red Dot award-winning headset. This is one of the most advanced headset microphones available—secure, durable and flexible. It’s perfect 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 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 individual performers for a perfect fit.

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.

DPA has 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 version of this mic is treated with a surface that mimics the color of the boom and adds a very distinct expression of the entire headset.

3-point ear grips
Most headsets have either a 1- or 2-point gripping system—resting on top of the ear or (sometimes) gripping below the ear. This DPA Microphones headset relies on a 3-point gripping system— adding a support area behind the ear pressing gently inward. This not only makes the headset sit more securely around the head even in jostling situations, but it also makes it extremely comfortable to wear over long periods. Furthermore, the advanced, ergonomic shape of these ear grips conforms to the shape of the head.

90° cable management system
The headset has its cable guide directly at the back of the headset frame, so that you can easily organize the cables to run unobtrusively down the back of the performers. The cable guide slides from side to side, so it can be moved out of, for example, the camera view. The special construction also separates the cables from the boom movement, which ensures that cables are not pulled on when the boom is moved. This helps ensure that the mic cable has a long life.

The cable is often the weak spot on these types of mics, but DPA Microphones has opted to use the same size cable (Ø 1.6 mm (.06 in)) as usual. They are extremely rugged, do not become entangled and are equipped with an inner core made of Kevlar that withstands rough pulls.

IP58 Certified
The CORE Miniatures are IP58 certified. This durability is achieved through a number of defense mechanisms:

Water-repellent 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
