The Shure RPW174 KSM8 Microphone Capsule Head is a replacement cartridge for all Shure wireless microphones, excepting those in the BLX and GLX-D ranges. By using Shure’s Dualdyne double diaphragm technology the worst proximity effects are avoided and both low and high-frequency handling noise is also kept to an absolute minimum. The result is a dynamic mic that provides the most neutral and accurate response possible, housed in a hard-wearing Shure enclosure.
