Perfect Combo For Your Wireless Presentation and Vocal Needs

The GLX-D+ Dual Band Digital Wireless is the ideal solution for musicians and performers who want to use wireless with confidence and hassle-free. Every aspect of it is managed automatically and completely reliably, so you can focus on performance. Thanks to new dual-band wireless technology, the GLX-D can operate on both 2.GHz and 5.8GHz, doubling the available bandwidth while intelligently avoiding interference to ensure reliable, uninterrupted audio. The included lithium-ion battery with smart charging for up to 12 hours of use (improved from the previous generation GLX-D) can be recharged in multiple ways and offers fast charging capabilities.

Available with several legendary microphone options (including the SM58®) in tabletop, half-rack and guitar pedal system configurations. Combined with a frequency manager and directional antenna accessories (both sold separately), rack-mount receiver systems are ideal for small to medium installations where more channels are required.

Always come through clear and precise to captivate your audience with transparent audio and durable setup from the GLX-D+ Dual Band and SM58 capsule. Don't let the fear of drop outs scare you. The dual band selects backup frequencies to keep the system (transmitter and receiver) ready to move in no-time in case interference occurs. The continuous interference monitoring enables a seamless switch without interruption during a performance. Keep performing reliably without any ongoing management.

This system includes the classic SM58 microphone, WL185 lavalier, and the GLXD4R+ half-rack receiver.
