Shure BLX4 Tabletop Wireless Receiver (H9: 512 to 542 MHz)

The Shure BLX4=-H9 is a tabletop wireless receiver that delivers dependable, clear audio for performers, presenters, and sound crews who want quick, frustration-free setup. Operating in the H9 band from 512 to 542 MHz, it works seamlessly with Shure BLX1 bodypack or BLX2 handheld transmitters to create a complete wireless system for spoken word, live music, or corporate events.

QuickScan handles frequency selection with a single button press, searching through 123 available channels and locking onto the clearest one in seconds. Once the system is running, microprocessor-controlled antenna diversity continually monitors the signal and switches to the stronger antenna when needed, helping prevent dropouts and keeping the show moving.

An operating range of up to 300 feet lets performers roam the stage, presenters walk the room, and fitness instructors move freely without losing connection. Up to 12 compatible systems can run in the same frequency band, making it practical for small bands, houses of worship, conference centers, or rental inventories that need multiple channels without complicated coordination.

Balanced XLR and unbalanced 1/4-inch outputs connect easily to mixers, powered speakers, or recording interfaces. Front-panel LEDs provide instant confirmation of audio level and RF status, while internal antennas keep the footprint small for travel and quick tabletop placement. A rugged ABS housing resists the bumps and scrapes of transport or daily use, so the receiver can handle life on the road as well as permanent installations.
