Shure BLX4R=-H9 Rack Mount Wireless Receiver H9 Band

The Shure BLX4R is a single-channel rack-mount wireless receiver designed for use within the Shure BLX Wireless System ecosystem. Built for small venues, houses of worship, presentations, and live performance setups, it provides the kind of consistent, interference-resistant audio that Shure is known for. The rack-mountable form factor keeps your gear organized and secure, while XLR and 1/4-inch outputs give you the flexibility to integrate with virtually any sound system. With support for up to 12 channels per frequency band, the BLX4R scales well for multi-microphone configurations without requiring a jump to a more expensive wireless platform.

Operating in the H9 frequency band, this receiver pairs exclusively with Shure BLX1 bodypack and BLX2 handheld transmitters in the same band — a critical detail to verify before purchasing. The system delivers a reliable wireless range of up to 300 feet, and the user-friendly front-panel controls make frequency selection and gain adjustment straightforward even during live events. Included in the box are rack mount hardware, a power supply, and a user guide, so installation is quick. For anyone building out or expanding a wireless rig with proven Shure reliability, the BLX4R is a practical, professional-grade foundation.
