Musicians and presenters can now break free from cables with complete confidence using GLX-D+ Dual Band Digital Wireless technology. This innovative system operates across both 2.4 and 5.8GHz frequencies, effectively doubling the available bandwidth whilst intelligently avoiding interference to ensure reliable, dropout-free audio performance.
The GLXD24+/SM58 Dual Band Vocal System combines the renowned industry-standard SM58® vocal microphone with superior transparent digital audio quality in a convenient half-rack format. Automatic frequency management works seamlessly with the new Dual Band Technology to provide consistent, reliable performance that professionals can depend on.
Power is never a concern thanks to Shure’s proprietary Lithium-Ion rechargeable batteries, which provide up to 12 hours of continuous use. This wireless solution eliminates complexity whilst maintaining the audio quality and reliability that serious musicians and presenters require for their performances.
