Shure SLXD14/SM35 Digital Wireless Cardioid Performance Headset Microphone System (G58: 470 to 514 MHz)

The Shure SLXD14/SM35-G58 is a headset microphone system that uses digital wireless technology to deliver clear, high-fidelity sound for performers, presenters, and installers who refuse to compromise on audio quality. Operating in the G58 UHF range between 470 and 514 MHz, it offers 24-bit audio resolution and a 120 dB dynamic range that captures every nuance of a voice without added noise.

The system pairs the SM35 headset microphone with the SLXD1 bodypack transmitter. The headset features a cardioid condenser capsule that focuses on the performer’s voice while reducing pickup of drums, amplifiers, and room reflections. A secure wire frame and adjustable boom keep the mic exactly where it belongs, making it ideal for singers who play an instrument, fitness instructors who move constantly, or corporate speakers who need both hands free.

The SLXD1 transmitter connects to the headset through a locking TA4F connector. It maintains a reliable signal up to 330 feet from the receiver and offers selectable RF output levels to suit different venues. Power comes from two AA batteries or the optional SB903 rechargeable pack, providing up to eight hours of continuous operation for stress-free sessions, rehearsals, or live events.

On the rack, the SLXD4 single-channel receiver simplifies setup. Removable antennas allow strategic placement, auto frequency scan finds a clear channel, and IR sync links the transmitter in seconds. A 60 dB gain range adapts to quiet speech or powerful vocals, while balanced XLR and quarter-inch outputs integrate easily with mixers, powered speakers, or recording interfaces.

Engineers can run up to thirty-two SLX-D systems in the same band, so the SLXD14/SM35-G58 scales from a solo presenter to a full stage production or multi-room installation. Its consistent signal, straightforward controls, and flexible power options make it a dependable choice wherever dependable wireless audio is required.
