It’s well-built from cast metal, so should give years of reliable service, especially if mounted in a rack cabinet. The GLXD4R is a neat-looking unit featuring an easy-to-read LCD screen that displays channel information, gain levels and remaining battery life. Range is quoted at 30 metres and battery life is up to 16 hours using the supplied lithium-ion battery, which can be recharged via the tidy dock that’s accessed via the front panel of the GLXD4R receiver. It’s a discreet-looking unit with just an on/off switch and a multi-coloured battery-status LED breaking up its functional lines. The housing is molded ABS, which is fine, though it doesn’t have the substance of some of the mics reviewed here. The bundled mic capsule is from an SM58 – perhaps the most iconic live microphone of all time – so you can have total faith in the sound quality. This kit forms part of Shure’s GLX-D Advanced ecosystem, which is where the US brand starts to get serious with its wireless products.
