Shure R183 Omnidirectional Cartridge

Product Overview

The Shure R183B is an omnidirectional replacement cartridge for Microflex-series microphones, including MX183, MX202, MX391, MX392, MX393, MX405, MX410, MX412, MX415, MX418, and WL183 models. Its 360-degree pickup pattern makes it well-suited for conference table installations, boundary microphone applications, and overhead miking where consistent capture from multiple talker positions is required. The black finish integrates with standard black Microflex hardware.

Product Description

The R183B threads directly onto compatible Microflex gooseneck, overhead, and lavalier microphone bodies with a simple cartridge swap — no soldering required. This makes it an efficient field-replaceable option for AV service technicians maintaining installed Microflex systems in conference rooms, training rooms, and commercial meeting spaces. The omnidirectional polar pattern captures sound equally from all directions with low handling noise, providing forgiving coverage for huddle rooms and round-table configurations where talker position varies. For facilities managing large Microflex deployments, stocking the R183B allows cartridge-level refresh without replacing entire microphone assemblies. Also available in bright white: see the Shure R183W-A. For installations requiring more focused pickup, consider the Shure R184B supercardioid cartridge or the Shure R185B cardioid cartridge.
