Shure GLXD24R+/Beta87A

The Shure GLXD24R+/Beta87A digital wireless system generates a digital output signal via an XLR and 6.3mm jack socket according to two different standards. The system additionally includes a USB-C interface to make firmware updates easy to install. Two different options are available for charging the lithium ion battery: The transmitter’s USB-C connection or the battery charging socket on the front of the receiver. At the heart of the microphone is Shure's popular Beta87A condenser capsule, whose supercardioid polar pattern suppresses sound coming from the sides and rear, and concentrates the mic capture primarily on the signal coming from in front. The receiver's LC display indicates which group and channel is active and how much battery life remains (in hours and minutes) as well as the audio volume level, signal gain level, and more. The incoming signal can be fed to a mixing desk via the XLR output, while amplifiers and small active PA systems can be fed via a jack cable.

The American company Shure began developing microphones during the early 1930s and is one of the pioneers of the audio engineering sector. Models such as the 55 Unidyne - known to many as the "Elvis microphone" - and the SM57 and SM58 which appeared in the mid-1960s are still ubiquitous in live sound production today. They enjoy cult status among musicians and technicians alike. In the 1990s, Shure introduced the first wireless microphones and in-ear monitoring systems and became a market leader in this field. In addition to microphones, Shure offers a wide range of earphones and headphones for studio and live use, as well as various accessories.
