Shure BLX14R/SM35 Rackmount Wireless Cardioid Performance Headset Microphone System

The Shure BLX14R/SM35-H9 is a complete system that pairs Shure wireless technology with the SM35 cardioid headset microphone, giving performers, instructors, worship leaders, and presenters the freedom to move naturally on stage or in front of a class.

The BLX4R receiver installs in a standard equipment rack and uses detachable antennas for convenient placement. Its QuickScan feature evaluates the local RF environment and selects a clear frequency with a single button press, so setup takes seconds even in crowded radio-frequency spaces.

The SM35 headset focuses on the performer’s voice through a cardioid pickup pattern that helps control feedback and reduces ambient noise. A lightweight frame keeps the mic stable during vigorous movement, making it well suited to dance numbers, fitness instruction, and animated speaking engagements.

The BLX1 bodypack transmitter runs up to 14 hours on two AA batteries and maintains a reliable link to the receiver at distances of up to 300 feet. Balanced XLR and unbalanced 1/4-inch outputs on the receiver connect directly to mixers, powered speakers, or recording interfaces, allowing the system to fit easily into portable rigs and permanent installations.
