Shure RPW170
KSM8 Capsule in Brushed Nickel for Shure Wireless Handheld Transmitters


Shure KSM8 Dualdyne Handheld Vocal Microphone Overview
Shure KSM8 Dualdyne Handheld Vocal Microphone – Technical Background

The Shure RPW170 is a KSM8 Dualdyne dynamic cardioid microphone capsule that is designed for use with the following Shure wireless handheld transmitters:

  • SLX2
  • UHF-R
  • QLX-D
  • ULX-S
  • ULX-D

The KSM8 cartridge was painstakingly crafted for the highest possible audio quality for live sound applications, and thanks to its Dualdyne dual-diaphragm design, it has the purest cardioid polar pattern available in a Shure product. This means that the off-axis rejection is incredibly smooth – even in high volume environments – so feedback is much less of a concern. Plus, the Dualdyne cartridge all but eliminates proximity effect, so there's no need to worry about artificially boosted low-end frequency content.

The Dualdyne cartridge features both active and passive diaphragms. The passive diaphragm is part of the cartridge's acoustic network to provide for the virtual elimination of proximity effect as mentioned above, as well as low-frequency handling noise. The patent pending Diaphragm Stabilization System (DSS) Technology protects and stabilizes the active diaphragm from unwanted excursion or rocking during plosives or impact to provide outstanding protection against high-frequency handling noise. This means that the Dualdyne cartridge is working twice as hard to provide the most accurate and neutral sound possible.

Shure RPW170 Features:

  • KSM8 Dualdyne dynamic cardioid cartridge for Shure wireless handheldtransmitters
  • Patented cartridge design featuring two ultra-thin diaphragms (one activeand one passive) and groundbreaking inverted airflow system
  • Exceptional control of proximity effect vastly increases working distancewithout on-axis coloration
  • Accurate frequency response due to controlled proximity effect whichallows for neutral mid-and-high frequency reproduction, resulting in the mostnatural sounding dynamic microphone available from Shure
  • Off-axis attenuation is flat and broad resutling in superior quality ofrejection of unwanted sound sources for increased vocal clarity
  • Neodymium magnet resides in a micro-injection mold of aerospace SoftMagmaterial that maximizes the magnetic field for maximum output level
  • The Dualdyne cartridge re-imagines the longstanding Shure PumpingPneumatic Shock Mount design with an elaborate mathematical architecture oftuned cavities, specific resistances, and precisely machined components thatare fully integrated into the cartridge's acoustic properties, resulting inexceptional handling noise without any loss of low-frequency response
  • Patent pending Diaphragm Stabilization System (DSS) Technology protectsand stabilizes the active diaphragm from unwanted excursion or rocking duringplosives or impact, providing substantial protection against high-frequencyhandling noise
  • Cutting-edge cartridge manufacturing methods utilize ultra-sonic andinternal laser welding to provide outstanding mechanical reliability
  • Dent-resistant, hardened carbon-steel grille design lined with hyrdophobicwoven fabric provides exceptional plosive and wind protection, while offeringvirtually waterproof protection
  • Brushed Nickel finish
