The world of wireless microphones has grown tremendously in recent years, thanks to the introduction of digital technologies for audio transmission. At the same time, users have not had it easy. In Poland, the lion's share of the bands used by wireless microphones for LTE (from almost 600mhz to over 800mhz) has been sold out, and while it is still possible to operate in many bands in this range (especially away from big cities), sometimes getting a free transmission channel is very difficult.
As a result, manufacturers of wireless systems are not only taking advantage of digital transmission with a narrower usable bandwidth per channel, but are testing the possibilities on bands previously used for, for example, WIFI. This is no different for Shure Brand, which has expanded its GLX line with the new GLX-D+ systems.
The series includes:
GLXD4R+ - halfRack receiver
GLXD4+ - tabletop receiver
GLXD6+ - stompbox receiver for pedalboard.
GLXD1+ - bodypack transmitter
GLXD2+ - handheld transmitter
GLXD+FM - 2.4 / 5.8Ghz antenna splitter
PA805DB-RSMA - 2.4 / 5.8Ghz directional antenna
Compared to its predecessor, the new plus devices operate in the 2.4 and 5.8Ghz bands. Accordingly, the entire series is equipped with a special splitter and directional antenna supporting both bands. The systems are simplified to the maximum. Band scanning is done automatically, as is the pairing of the transmitter with the receiver. What's more, the manufacturer claims that the intelligent frequency management function constantly monitors the frequency spectrum and, without interruption of transmission, switches the devices to a clean channel when interference occurs.
The issue of battery charging has also developed strongly. I must admit that I am a fan of the solution in which the battery charging slot is integrated into the base ( this does not apply to the stompbox version of the receiver ). In addition, Shure further allows transmitters to be charged using a USB-C cable.
For the plus series, Shure has envisioned a new SB904 battery that allows - under optimal conditions, of course - for 12h of operation. What's more, fast charging is already entering pro audio equipment - 15 minutes of charging is supposed to be enough for 1.5h of use.
Personally, I am not a fan of solutions based on WiFi-like bands. Especially since these bands are often very dense (city centers) and band usage is completely unregulated. No less, I can see that this technology is constantly moving forward. I think the GLX-D+ system could be an interesting solution for local artists, small bands, community centers or for guitarists (Stompbox version) who don't like to hang on to cable.
The most important thing, after all, is that signal transmission should be uninterrupted. Will the Shure GLX-D+ provide that comfort? Time will tell. All configurations and accessories can be found on the manufacturer's website.
