MX183, MX184, & MX185

Interchangeable cartridges and accurate sound reproduction in a tiny, unobtrusive lavalier microphone.

Features:

• Wide dynamic range and frequency response for accurate sound reproduction across the audio spectrum
• Interchangeable cartridges that provide an optimal choice for each application
• Rotatable tie-clip that pivots in 90 degree increments for placement flexibility
• Supplied snap-fit foam windscreen that controls breath noise and stays on securely
• Balanced, transformerless output for increased immunity to noise over long cable runs
• Supplied dual tie clip holds two microphones for dual miking applications

Microflex® Lavalier microphones bring a new level of sophistication to personal voice reproduction. Like all Microflex family microphones, the 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.
