Product Overview
The Shure R185B is a cardioid replacement cartridge for Microflex-series microphones in black finish. Its 130-degree pickup angle at -3 dB provides a balanced combination of directional focus and coverage width, making it appropriate for conference table goosenecks, lecterns, and installed boundary microphone applications where a broader capture area than supercardioid is needed while still rejecting sound from behind the capsule. Compatible with MX and WL Microflex gooseneck, overhead, boundary, and lavalier models.
Product Description
The R185B threads directly onto compatible Microflex microphone bodies via a tool-free cartridge swap, enabling fast field replacement in installed AV systems. The cardioid polar pattern provides good off-axis rejection — particularly from behind — while offering a wider acceptance angle than supercardioid, which benefits applications where the talker's head position varies slightly or the microphone is at a slight distance. For AV integrators managing installed Microflex deployments, the R185B allows polar pattern changes at the cartridge level without replacing full microphone assemblies. Use of a windscreen is recommended per Shure documentation. Also available in bright white: see the Shure R185W-A. For tighter pickup, see the Shure R184B supercardioid cartridge.
Key Features
- Cardioid Polar Pattern — 130-degree pickup angle at -3 dB provides balanced directional capture with wider coverage than supercardioid, suitable for varied talker positions.
- Good Off-Axis Rejection — Cardioid pattern rejects sound from behind the capsule, reducing pickup of room noise and adjacent sound sources in commercial AV environments.
- Windscreen Recommended — Shure recommends windscreen use with cardioid cartridges to minimize breath noise in close-miking applications.
- Tool-Free Threaded Installation — Screws directly onto compatible Microflex microphone bodies for fast, solderless field replacement.
- Black Finish — Matches standard black Microflex hardware for a consistent appearance across commercial AV installations.
