The black 4466 CORE Omnidirectional Miniature Microphone with Boom for Headset from DPA is a lightweight cardioid microphone with an adjustable boom mechanism designed for use with DPA headsets. The DPA 4466 and 4488 headset mics are modular and use the same headset design, allowing you to substitute the original boom mechanism and microphone for one featuring a different pickup pattern. This allows the user of a 4488 headset to swap out that model s directional (cardioid) headset for this 4466 omnidirectional version-saving you the expense of purchasing an entirely new headset.
The forgiving omnidirectional polar pattern in the 4466 captures audio in a 360° pickup pattern around the mic, providing consistent audio levels and offering a clean, natural, and transparent sound. The 2-way adjustable boom system-length and height-features an anti-rotate mechanism that makes it easy to position the tiny 5mm mic capsule for optimal sound quality. A sliding lock mechanism secures the boom positioning.
DPA s CORE technology is at the heart of the electret-condenser capsule, providing an ultralow noise floor and wide dynamic range. With an SPL rating of 144 dB, the microphone is more than capable of handling loud speakers, vocalists, and presenters to deliver clean, transparent, and reliable sound for critical performances and presentations.
