Description

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.

Features:

  • One-size-fits-all - head sizes and shapes
  • Comfortable 3-point grip - above, below, behind the ear
  • Easily adjustable - frame size, boom length, placement
  • 90 deg. adjustable cable guide - keeps cable out of sight
  • Non-reflective PVD surface on headset frame, boom, capsule


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 individual 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.

It also has 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.

3-point ear grips
The ear grips on our new headset consist of some amazing technology. Most headsets have either a 1- or 2-point gripping system - resting on top of the ear or (sometimes) gripping below the ear. This 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 even over long periods. Furthermore, the advanced, ergonomic shape of these ear grips conforms to the shape of the head.

90 deg. 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 have a long life.

The cable is often the weak spot on these types of mics, but DPA has opted to use the same size cable (O 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 and are the highest standard on the market.

The cable, capsule and boom design, ensure immunity to noisy wireless devices. Headsets are typically connected to a wireless belt pack and DPA offers a comprehensive mix of adapters to suit the many wireless transmitters available. When used with an adapter, the connector is a MicroDot, but they also offer hardwired terminations to suit the most popular systems from manufacturers such as Shure and Sennheiser. All of these connectors are equipped with a rugged strain relief.

Adapter system gives you flexibility
The adapters for wireless systems give you flexible, simple and affordable possibilities. You are no longer bound to only one wireless system. As circumstances change, you can just switch your adapter, instead of incurring the cost of a completely new microphone. When you make the switch, you won't hear any loss or change in sound quality from the mic as the adapters are tailored to suit specific transmitter types.

DPA's miniature microphones work with all leading wireless mic solutions, such as Lectrosonics, Sennheiser, Shure, Sony, Wisycom, Zaxcom and many more. DPA Microphones' ingenious adapter system is one of a kind in the industry. It protects your investment in fantastic sound for years to come. Should you prefer to have your mic hardwired to a specific connector type, DPA offers pre-terminated types for the most popular wireless systems.

IP58 certified
The CORE Miniatures are IP58 certified. This durability is achieved through a number of defence 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
