Overview

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 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.

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.
