Featuring the SM35 headset microphone, QLXD14/SM35 wireless mic system with headworn microphone combines professional features with simplified setup and operation.

The SM35 Performance Headset Microphone

Great for multi-instrumentalists and active performers who need their hands free, the SM35 is lightweight and low-profile, so you can concentrate on your performance and your audience can enjoy it without distraction. The SM35 features a wireframe headset design that fits both securely and comfortably, allowing for long-term, confident performances. This mic also comes with a pair of interchangeable locking snap-fit windscreens, the perfect accessory for minimizing pickup of plosives, breath, and wind noise for a clean, intelligible sound.  

The SM35’s tight, unidirectional cardioid pattern lets you focus on the sound you want to capture, providing excellent rejection of off-axis noises, preventing feedback from other electronic equipment such as floor monitors, and minimizing on-stage signal bleed. This makes it an ideal choice for a wide range of applications, from small clubs to large installations--and even arena tours. Get even better positioning via the mic’s flexible gooseneck design, which allows you to further isolate your sound from unwanted noises.

The QLXD1 Bodypack Transmitter

Transparent 24-bit digital audio quality and incredibly efficient RF spectrum usage make the QLXD1 bodypack transmitter ideal for wireless vocals and instruments in presentation spaces, music venues, houses of worship, and more. With over 120 dB of dynamic range, you won’t need to adjust any transmitter gain. This bodypack also comes with AES 256-bit encryption, giving you confidence that every transmission is secure.

Boasting an easy-to-read backlit display, this bodypack is designed for intuitive, efficient use. Use selectable display mode to personalize what settings are shown, choose the desired group/channel, frequency, or battery runtime (when using the optional Shure SB900B battery, sold separately). The QLXD1 quickly syncs with a wireless receiver over IR at the push of a button and maintains a clear, uninterrupted signal over its entire 100 m (330 ft.) range, with no transmitter gain adjustments needed.

The QLXD1 features all-metal construction to ensure durability, while a wide selection of compatible microphone choices offer legendary Shure sound signatures. This bodypack also comes with a detachable ¼ wave antenna. Additionally, the QLXD1 includes external charging contacts, allowing for docked charging.

The QLXD4 Digital Wireless Receiver

Get the perfect balance of professional features and intuitive efficiency with the QLXD4 digital wireless receiver. This receiver offers transparent 24-bit digital audio quality and incredibly efficient RF spectrum usage. Streamline your workflow: Find open frequencies fast with automatic scanning, then deploy them to transmitters using one-touch IR sync.

Experience expanded capabilities with ethernet networking. This allows you to use networked channel scanning across multiple receivers, remotely control settings from your computer via Wireless Workbench® software integration, and remote monitoring from iOS devices is also available (via the ShurePlus™ Channels Mobile App).

More about the QLX-D Digital Wireless Systems
