Shure RPW174 KSM8 Wireless Capsule for Shure Transmitters - Black

Bring KSM8 Dualdyne vocal performance to a compatible black Shure wireless handheld transmitter with the Shure KSM8 Wireless Capsule for Black Shure Transmitters. The RPW174 is an interchangeable replacement or upgrade capsule—not a complete wireless microphone system—and is designed for professional vocal performance, presentations and demanding live applications. Its dual-diaphragm dynamic moving-coil cartridge uses two ultra-thin diaphragms, one active and one passive, with an inverted airflow system to provide greater control over proximity effect. Combined with a cardioid polar pattern and 40Hz–16kHz frequency response, this design helps preserve clear, natural vocal reproduction as the performer moves closer to or farther from the microphone.

Dual-Diaphragm Technology Controls Vocal Proximity Effect

Unlike conventional single-diaphragm dynamic microphone designs, the KSM8 Dualdyne uses its active and passive diaphragms with an inverted airflow system to control the low-frequency buildup that can occur as a performer moves closer to a directional microphone. This helps maintain a more consistent tonal balance across a wider working distance, preserving natural midrange and high-frequency reproduction. For singers, presenters and other performers who move naturally while using a handheld microphone, that control supports a more dependable vocal sound from one moment to the next.

Cardioid Pickup and Rugged Stage Protection

The cardioid polar pattern focuses pickup toward the performer while reducing unwanted off-axis sound, supporting vocal isolation in live-performance and presentation environments. An integrated pneumatic shock-mount system helps minimize handling noise without compromising low-frequency response. The hardened carbon-steel grille incorporates hydrophobic woven fabric for added protection against plosives, wind and moisture. Finished in black, the capsule provides a discreet visual match for compatible black Shure handheld transmitters.

A Direct Upgrade for Compatible Shure Handhelds

For users of compatible Shure wireless handheld transmitters with interchangeable capsules, the RPW174 offers a direct way to add KSM8 Dualdyne performance without replacing the entire system. One black capsule is included; a wireless transmitter is sold separately. The Shure KSM8 Wireless Capsule for Black Shure Transmitters combines controlled proximity effect, cardioid vocal isolation and durable protection in an interchangeable wireless-capsule format.
