DPA 4488-DC-R-F34 4488 CORE Directional Headset Microphone, Beige, Mini-Jack
The 4488 CORE Directional 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.
The 4488 CORE Directional Headset Microphone offers an open and natural sound making it ideal for both spoken word and vocal performance applications. It provides excellent off-axis rejection in high-SPL situations. It efficiently suppresses distant sound sources making it perfect for demanding live performance environments where background noise and feedback are concerns. The bass response is designed for optimal linearity at 2-3 cm (1 inch) from the sound source. This means that the bass roll-off will be relatively prominent at a greater distance – a paramount factor when it comes to rejection of background noise and in the fight to avoid feedback.
Technically advanced mechanical headset mount construction
The new 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.
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 be extended or shortened, so that it can be placed at the corner of the smile. It can also be pivoted up and down at a fixed point below the ear (no more bending the boom) for even more precis placement. 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.
