Super-directional double gooseneck conference microphone U857QU
Engineered for high-quality audio applications such as reception, recording, television broadcasting, and conferences with stringent requirements.
UniLine? ultra-directional microphone, offering a narrow reception angle of 90°.
Excellent soundproofing design that prevents feedback even at high gain levels.
UniGuard? - Radio Frequency Interference (RFI) Shielding Technology, offering protection against RFI to prevent interference during reception, such as from mobile phones.
Adjustable, durable, slender, and non-memory bendable goose-neck structure, allowing for quick and flexible positioning of the microphone's pickup head.
UniSteep® - High-pass filter, providing an efficient high-pass filter that attenuates low-frequency noise without compromising voice quality.
Built-in microphone preamplifier power component; no need for an external power module.
Swappable microphone head design, available with compatible microphone heads for various applications. The reception angle ranges from 90° to 360°.
Equipped with a double-layer windproof foam cover, it reduces the occurrence of unpleasant jet and wind noises during speaking.
Rapid installation design, with a standard 3-pin Cannon XLRM connector at the microphone terminal, compatible with conference microphone stands designed with a 3-pin Cannon XLRF female connector. It can also be directly connected to a soundboard as needed.
Optional desktop anti-vibration microphone stand, which securely mounts the microphone on a desk or other flat surface, reducing impact and vibration noises when the microphone collides with the surface.
