Description

Overview

The Shure RK100PK is an in-line preamplifier designed to protect Shure MX microphones from radio frequency interference that can cause buzzes and dropouts. It does not alter the microphone’s tone but ensures a clean signal by blocking noise from nearby transmitters, lighting equipment, and grounding issues. This unit connects easily with a standard 3-pin XLR connector and draws power from phantom power supplies, eliminating the need for batteries or external adapters.

Its compatibility with a broad range of Shure capsules—including lavalier, headset, boundary, and podium microphones from the MX, Beta, SM, WL, WBH, and PG series—makes it a versatile choice for environments like broadcast booths, corporate boardrooms, houses of worship, and live event venues where multiple mic types are used.

Product warranty

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
