BLX4=-H9 Wireless Receiver

The Shure BLX4 is a single‑channel analog wireless receiver designed for use with Shure BLX wireless microphone systems. The H9 designation means it operates in the 512 MHz to 542 MHz frequency band, making it suitable for regions where that band is supported. It’s built to be simple to set up and use, with intuitive controls and reliable performance. The receiver uses microprocessor‑controlled internal antenna diversity to maintain stable RF reception and reduce signal dropouts. One‑touch QuickScan technology lets you automatically find a clear frequency if interference is present. The unit offers both balanced XLR and unbalanced ¼″ outputs so it can connect to mixers, PA systems, and other audio equipment. Front‑panel LEDs give visual status for RF channel and audio levels.
