Shure SLXD14/SM35 Digital Wireless Cardioid Performance Headset Microphone System (J52: 558 to 602 + 614 to 616 MHz) - SLXD14/SM35-J52

Product Overview

The Shure SLXD14/SM35 is a digital wireless headset microphone system built for presenters, instructors, and worship leaders who need hands-free operation with clear speech reproduction. It combines the SLX-D digital wireless platform with the SM35 cardioid performance headset microphone. Operating in the J52 band (558 to 602 + 614 to 616 MHz), the system delivers transparent 24-bit digital audio and stable RF for auditoriums, training rooms, and houses of worship. A rack-mountable SLXD4 receiver and SLXD1 bodypack transmitter make it straightforward to integrate into a commercial AV rack.

Product Description

This SLX-D headset microphone system pairs the SLXD4 single-channel receiver with an SLXD1 bodypack transmitter and the SM35 headworn microphone for hands-free, hands-on presenting. The SM35 is a cardioid electret condenser headset with a flexible gooseneck for repeatable mic placement and a tight unidirectional pattern that rejects off-axis sound to control feedback in live rooms. Its TA4F (TQG) connector mates directly with the Shure bodypack. As a 24-bit digital wireless system, SLX-D provides clean audio and predictable frequency coordination, supporting up to 32 compatible systems per 44 MHz band for multi-room deployments. The J52 band covers 558 to 602 MHz plus 614 to 616 MHz. The SLXD4 receiver mounts in a standard AV rack and feeds a DSP, mixer, or conferencing processor, making this a dependable hands-free presenter wireless microphone for auditoriums and multi-purpose rooms. Locking snap-fit windscreens tame plosives and breath noise for consistent intelligibility.
