Dependable Wireless Audio that Anyone Can Use

GLXD2+/B58 Handheld Transmitter
Featuring the industry standard BETA®58A vocal microphone, the new GLXD2+/B58 Dual Band Handheld Transmitter delivers superior, transparent digital audio. The perfect combination of the automatic frequency management with the new Dual Band Technology provides reliable and consistent performance while Shure proprietary Lithium-Ion rechargeable batteries provide up to 12 hours of use. Go wireless without complication.

Portable Tabletop Receiver
- This configuration includes a portable tabletop receiver made from durable ABS plastic with front-panel charging for the SB904 battery and an easy-to-read display that shows pertinent information.
- The system transmits audio with a flat, 20 Hz to 20 kHz frequency response and 120 dB of dynamic range, leaving the sound of your mic unaffected by the wireless components.
- The transmitter’s input gain can be wirelessly adjusted right from the receiver’s front panel to optimize the audio signal.
- The rear panel provides a balanced XLR output switchable between mic and line levels along with a balanced 1/4″ Inst/Aux output.

A tireless performer
GLX-D+ Dual Band Digital Wireless is the perfect solution for musicians and presenters who want to go wireless with confidence, and without complexity. Every aspect of its operation is managed automatically and with total reliability, allowing you to focus on your performance.
With new Dual Band Wireless Technology, GLX-D+ can operate in both 2.4 and 5.8GHz, more than doubling the available bandwidth while also intelligently avoiding interference for reliable, dropout-free audio. Featuring smart rechargeability with up to 12 hours of runtime (improved from prior generation GLX-D), the included lithium-ion battery can be charged multiple ways and offers quick charge capabilities. A quick charge feature allows for 1.5 hours of use from a 15-minute charge.
Available with multiple legendary microphone options (including the SM58®) in tabletop, half-rack and guitar pedal system configurations. When combined with Frequency Manager and directional antenna accessories (both sold separately), the rack-mount receiver systems are ideal for small and medium installations where a larger number of channels is needed.
