Setting new standards for the broadcast industry
Already the worldwide leader in headset mics for theatre and broadcast applications, the d:fine™ In-Ear Broadcast Series now adds an integrated in-ear monitor to create a broadcast and communication headset with outstanding acoustic performance and feather-light comfort.
The in-ear drivers allow no audio leakage to the microphone capsule. They are easily driven due to their high sensitivity. Two sizes of ear-pads are included to fit most ears.
The cable steer, located at the headset mount, controls the cable run down the neck. You can easily adjust the headset mount size.
These innovative headsets – the first of their kind – are designed for broadcast professionals who insist on superior voice reproduction without compromising on simple setup and daylong comfort.
d:fine™ 4266 Omni In-Ear Headset Mic
The d:fine™ 4266 Omni In-Ear Broadcast Headset Microphone combines the legendary sound of the 4066 Omnidirectional Capsule with a lightweight and flexible headset system and an in-ear driver. This condenser mic is easy and fast to adjust and it offers clean and transparent sound quality with lots of headroom.
Like all of the microphones in the range, the d:fine™ 4266 Omni In-Ear Broadcast Headset Microphone offers accurate, natural voice intelligibility and very high SPL capabilities. The mics effortlessly handle up to 144 dB peak before clipping. In addition, due to their exquisite linear response, low distortion and extremely broad dynamic range, they sound great no matter what the application. The d:fine™ 4266 comes with a Single In-Ear earpiece and is available in black and beige.
A bit about omnis
An omnidirectional microphone has sensitivity at all angles – in principle picking up sound equally from all directions. This gives you extremely natural and realistic sound compared to a cardioid mic. Omni mics are often used for picking up ambient sounds, as well as miking a large sound source such as a choir in a recording situation. Unfortunately, due to their pickup pattern, omnis can also produce a lot of feedback in live situations.
Nonetheless, we recommend that you try a DPA omni first because, when used close to the sound source, the equal frequency response makes these mics a flexible addition in your audio toolbox. It will often give a more natural sound, it can handle extremely high sound pressure levels, it does not suffer from proximity effect and is not as sensitive to wind, pop or handling noise.
Adapter system gives you flexibility
The adapters for wireless systems give you flexible, simple and affordable possibilities. You are no longer bound to 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.
The d:fine™, d:screet™ and d:vote™ series of 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.
