Cynthia Wisehart on Shure’s GLX-D+ Dual Band Wireless System

Early this month, Shure debuted a new GLX-D+ dual band wireless system. Much was made over the guitar and vocalist support. Yes, the microphone was designed with a particular eye to guitar support, but it’s a broadly applicable product, and I wanted to single it out, as I sometimes do on the back of walkthroughs with product manager.

I naturally zeroed in on the implications for installed environments where a robust budget-conscious wireless system can change the available options on a project. Where in the past, wireless might have been too expensive or complex, this could be a fit for worship, schools, corporate presentations, lectures, etc. We have a lot of choice a the high end; this product seemed like it could broaden the wireless field.

This is not just a case of value engineering. Shure says this new generation is a major enhancement from the previous generation that more than doubles available bandwidth; it can operate in 2.4GHz and now 5.8GHz, automatically scanning for and selecting the cleanest available frequencies.   In addition to the nifty guitar pedal receiver option, it’s available in rackmount and tabletop options with a wide selection of lavalier, headset, and handheld microphone choices— including Shure’s flagship SM58.

We’re told there are battery life improvements on the rechargeable battery; Shure claims a 12-hour runtime. A quick charge capability promises 1.5 hours of use from a 15-minute charge—a lifesaver in many situations for example when someone forgets to charge a mic well in advance to charge a mic. The new lithium-ion SB904 battery can be charged directly on the tabletop and half-rack receivers or through a USB-C connector on the transmitter. Shure has estimated that the rechargeable battery will save 2000 alkaline batteries.

Shure explained the objective to improve RF performance, antenna distribution, and management for up to eleven half-rack systems in typical environments (16 under optimal conditions)- -this requires a separately available Frequency Manager and directional antenna accessories.

GLX-D+ systems and components are available in various configurations for both installed and touring. Since all GLX-D+ Dual Band  Wireless systems operate in a license-free frequency range, users won’t have to worry about technical hurdles while traveling.

One of the pleasures of my job is the opportunity to get an introduction to new and innovative products with the product managers. This is a product that stood out for me. It also kicks off that time of year when new products will start to make the scene at NAB and InfoComm, when the fruits of everybody’s labor— sometimes years of labor—come into the spotlight.
