The Shure GLXD24R+/Beta58 is a digital wireless system that includes a dynamic handheld microphone transmitter, and its dual-band design operates in the 2.4GHz and 5.8GHz frequency ranges with a transmission output of 10mW, which provides a range of up to 60m. The system's automatic frequency management technology means that it always selects the signal frequency with the best reception, and it can also switch to interference-free carrier frequencies during operation without any loss of audio signal. The scope of delivery also includes a rechargeable lithium ion battery for the transmitter, a power adapter for the receiver, a carrying case, and a rack-mounting kit.
The Shure GLXD24R+/Beta58 generates a digital output signal according to two different standards, and 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 Beta58A dynamic 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 using 6.35mm jack cables.
The GLXD24R+/Beta58 system's simple and intuitive operation makes it a good choice for newcomers to the world of wireless systems, but its design and features, such as the robust metal construction of the transmitter and receiver, also make it an interesting proposition for more advanced users who plan to use it frequently. Those looking for an easy-to-use wireless system that can be operated with up to 16 transmission paths at once can do this by utilising the 2.4GHz and 5.8GHz frequency bands simultaneously. Alternatively, up to eleven receivers can be operated at the same time using just the 2.4GHz setting. And fans of rackmount installations will no doubt appreciate the 19" rack compatibility of the receiver, which measures 19.7cm in width and 4.2cm in height and features rear-mounted antennae. As mentioned above, a rack-mounting kit is included in the scope of delivery to make this process as easy as possible.
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.
The Shure GLXD24R+/Beta58 is a versatile wireless solution that is not restricted to operation with the matching handheld transmitter: Shure additionally offers a pocket transmitter (availabe separately) to allow the receiver to be used in conjunction with lavalier microphones and headsets, and this is also suitable for instrument signals. Whatever the case may be, users can look forward to up to 12 hours of operation on a single battery charge using the transmitters in this system, and the battery level indicator makes it easy to see when the next recharge is needed. Even if only one transmitter can be used with the receiver at once, it is still possible to couple it with two transmitters simultaneously, allowing the user to change microphones or instruments much more quickly. Last but not least, the stationary receiver features a backlit display with three different brightness settings - a blessing on dark stages.
