Shure RPW170 – KSM8 Dualdyne Wireless Capsule for Nickel Transmitters

Product Overview

The Shure RPW170 is a brushed nickel KSM8 Dualdyne wireless capsule compatible with Shure interchangeable handheld transmitters, enabling wireless deployment of the KSM8’s dual-diaphragm cardioid dynamic performance. Designed for commercial AV integrators maintaining premium Shure wireless microphone systems, the RPW170 delivers the natural tonal balance and dynamic performance of the KSM8 in a wireless capsule format, and is the correct capsule for nickel-finished Shure transmitters. It is compatible with select Shure handheld transmitters across the ULXD, QLXD, SLXD, and Axient Digital platforms.

Product Description

The KSM8 Dualdyne design uses two diaphragms working in concert within a dynamic transducer, providing extended frequency response that is characteristic of condenser microphones while retaining the SPL-handling durability of a dynamic. This technology is particularly beneficial in high-SPL commercial AV environments, house of worship applications, and live reinforcement where both vocal detail and reliable dynamic behavior are required. The RPW170 brings this performance to Shure’s interchangeable wireless platform, making it suitable as a wireless capsule upgrade or OEM replacement for existing KSM8 wireless deployments. The brushed nickel finish matches nickel-body Shure wireless transmitters for a cohesive system appearance. For a comparable capsule in black finish, see the Shure RPW174.

Key Features

• Dualdyne Technology — Dual-diaphragm dynamic transducer design extends the frequency response of a dynamic capsule, providing condenser-like detail with dynamic-class durability in commercial AV and live sound deployments.
• Cardioid Polar Pattern — Cardioid directionality delivers natural off-axis rejection suitable for vocal reinforcement in commercial meeting spaces, houses of worship, and live events.
• Brushed Nickel Finish — Designed specifically for nickel-finished Shure wireless transmitters to maintain system aesthetic consistency.
• Wireless System Compatibility — Compatible with select Shure handheld transmitters in the ULXD, QLXD, SLXD, and Axient Digital families that accept interchangeable capsules.
• Dynamic Transducer Durability — Dynamic transducer construction handles high-SPL environments without the phantom power requirements or humidity sensitivity associated with condenser capsules.

Typical Applications

• House of worship wireless vocal reinforcement requiring extended dynamic range
• Boardroom and conference room wireless microphone systems
• All-hands rooms and multi-purpose commercial meeting spaces
• Live sound reinforcement in auditoriums and performance venues
• Commercial meeting space installations with premium wireless infrastructure

Frequently Asked Questions

What is Shure’s Dualdyne technology?
Dualdyne is Shure’s dual-diaphragm design for dynamic microphone capsules. Two diaphragms work in tandem within a single dynamic transducer housing, extending the frequency response beyond what a single-diaphragm dynamic can achieve. This delivers detail and clarity closer to condenser performance while maintaining the SPL handling and durability of a dynamic capsule.

Why is the RPW170 nickel-specific?
Shure offers the KSM8 wireless capsule in two finishes to match the body color of compatible transmitters: nickel (RPW170) and black (RPW174). While both deliver identical acoustic performance, selecting the correct finish maintains consistent system appearance. Use the RPW170 with nickel-bodied Shure wireless transmitters.

Which Shure wireless systems are compatible with the RPW170?
The RPW170 is compatible with Shure handheld transmitters in the ULXD, QLXD, SLXD, and Axient Digital families that accept interchangeable capsules. Always confirm compatibility with your specific transmitter model against Shure’s published compatibility list before ordering.

Is the RPW170 suitable for commercial installation or only for touring?
The RPW170 is appropriate for both installed commercial AV systems and touring deployments. Its dynamic transducer construction makes it particularly well suited to venues and commercial spaces where humidity, temperature variation, or high SPL would put condenser capsules at a disadvantage.
