Shure QLXD2/SM58 Handheld Wireless Microphone Transmitter (X54 Band)

Iconic SM58 Sound with Advanced Digital Wireless

The Shure QLXD2/SM58 Wireless Digital Handheld Transmitter, operating on the X54 frequency band (902–928 MHz, subject to Australian regulations), features the legendary SM58® dynamic vocal microphone capsule, delivering transparent 24-bit/48 kHz digital audio for vocalists and presenters across Australia. Designed for use with QLX-D® Digital Wireless Systems (receiver sold separately, e.g., QLXD4, QLXD4D, or QLXD4Q), this transmitter offers pristine audio quality, robust RF performance, and AES 256-bit encryption, making it ideal for mid-sized venues, houses of worship, and professional presentations.

Legendary Vocal Clarity

The SM58 capsule is the industry standard for live vocals, featuring a cardioid polar pattern that minimizes background noise and feedback for focused audio capture. Its tailored frequency response (50 Hz – 15 kHz) with a brightened midrange and bass roll-off delivers warm, clear vocals that cut through the mix, perfect for live music, speeches, and broadcast. The QLXD2 transmitter provides a 20 Hz – 20 kHz range (microphone-dependent) with a flat response, ensuring accurate sound reproduction. Proprietary Shure Gain Ranging automatically adjusts input levels for consistent performance without manual tweaks.

Advanced Features and Durable Design

The QLXD2/SM58 leverages Shure’s advanced digital wireless technology, offering a 26 MHz tuning bandwidth in the X54 band with up to 17 compatible systems in a 6 MHz TV band or 21 in an 8 MHz range (region-dependent). Digital predictive switching diversity ensures reliable RF performance, and AES 256-bit encryption provides secure transmission for sensitive applications. The rugged, lightweight aluminum body features a backlit LCD for group/channel, frequency, or battery runtime display. IR sync enables quick pairing with QLX-D receivers, and the system supports networked control via Wireless Workbench® software or ShurePlus™ Channels iOS app. The transmitter offers up to 9 hours of operation with two AA batteries (included) or 10 hours with an optional Shure SB900B lithium-ion battery, with external charging contacts for compatibility with SBC200 Dual Docking Charger. The interchangeable capsule design supports other Shure capsules (e.g., Beta 58A, SM86, KSM9) for versatile applications.
