Shure R184 Supercardioid Cartridge for Microflex Series Microphones (Black)

The Shure R184B is a supercardioid cartridge designed for Microflex series lavalier, boundary, gooseneck, and overhead microphones that accept interchangeable capsules. It gives your existing microphone a focused pickup that covers a 115° arc in front of the capsule. By concentrating on sound coming from the front, the cartridge helps cut room noise and keeps feedback under control when loudspeakers or stage monitors are nearby.

Engineers reach for this cartridge when they want to tighten the coverage of a podium microphone in a reverberant lecture hall, capture a single voice during a panel discussion, or isolate a choir section with an overhead installation. The same approach benefits broadcast booths, houses of worship, and conference rooms where gain before feedback and clear speech are always priorities.

Because Shure built the R184B to match the acoustic performance of the original Microflex components, you can swap it with confidence. Installation takes only a quick twist and click, with no soldering or recalibration. You keep the microphone body you already own while changing the pickup pattern in seconds.

The cartridge works with any Microflex model that supports interchangeable capsules, including lavaliers WL183, WL184, and WL185 along with gooseneck and boundary options ranging from the MX183 series through the MX690. That broad compatibility makes it a practical choice for rental inventories, permanent installations, and touring systems that rely on Shure Microflex microphones.
