The SLXD14+/SM35 digital wireless system combines the SLXD1+ bodypack transmitter with the SM35 performance headset cardioid condenser microphone, delivering crystal-clear 24-bit audio with over 118 dB dynamic range. Designed for professional engineers, performers, and seasoned volunteers, the system ensures rock-solid RF performance across a 138 MHz tuning range, supporting up to 14 simultaneous systems in crowded 8 MHz TV bands.
With Automatic Setup, linked SLX-D+ receivers and transmitters maintain a stable connection even in challenging RF environments. ShowLink technology allows remote adjustment of transmitter settings directly from the receiver, including frequency changes, power-level control, locking and unlocking controls, and firmware updates. Full system monitoring and management are available through Wireless Workbench desktop software or the WWB Mobile app, via Wi-Fi or Bluetooth.
Every SLXD14+/SM35 system includes AES-256 encryption for secure audio transmission and Shure's Digital Feedback Reducer to minimize unwanted feedback automatically. Powered by two AA batteries or optional Shure SB903 rechargeable Li-ion batteries, the system provides up to 8 hours of continuous operation, making it ideal for live performance, presentations, corporate events, and stage productions where hands-free mobility and high-quality sound are critical.
