Shure : MX185
Description
The Shure Microflex Microphone Series
MX 185 bring a new level of sophistication to personal voice reproduction. Like all Microflex family microphones,
the MX-185 Lavaliers use Shure’s interchangeable condenser cartridges, available in cardioid, supercardioid or omnidirectional polar patterns. That means you can be sure there is a Microflex Lavalier that’s right for your application. Compatible with all Shure wireless bodypack transmitters, their high sensitivity and wide frequency response guarantee great sound.
Features
→ Wide dynamic range and frequency response for accurate sound reproduction→ Interchangeable cartridges that provide a choice of polar pattern for each application→ Rotatable tie-clip that pivots in 90° increments for placement flexibility→ Dual tie-clip and belt-clip preamp→ Supplied with snap-fit foam windscreen that controls breath noise→ Balanced, transformerless output for increased immunity to noise over long cable runs→ RF filteringSpecifications
