Note: only compatible with GLXD+ series.
The Shure GLXD2+/Beta58 is a handheld vocal microphone with transmitter for the GLXD+ series of digital wireless systems. When used with a compatible receiver, a dual-band transmission path is created that works in the 2.4GHz and 5.8GHz frequency ranges and can be operated both cost and licence-free. The transmitter also provides a maximum range of up to 60 metres courtesy of a transmission output of 10mW. The system's automatic frequency management technology means that the compatible receivers always select the signal frequency with the best reception, and the system can also switch to interference-free carrier frequencies automatically during operation without any loss of audio signal. The transmitter also comes with a rechargeable lithium ion battery.
At the heart of the GLXD2+/Beta58 microphone is Shure's popular Beta58A dynamic capsule, which features an optimised frequency response for vocals and a supercardioid polar pattern that suppresses sound coming from the sides and rear, and concentrates the mic capture primarily on the signal coming from in front. The microphone converts sound from 50Hz to 16kHz to cover all vocal-related frequencies and, at a level of -51.5dBV/Pa, has a noticeably higher sensitivity than the equally popular SM58 capsule. The removable battery, which is also compatible with the GLXD1+ bodypack transmitter, can be conveniently charged via the transmitter's USB-C socket or by using the battery charging socket on the front of one of the stationary receivers. A low weight of around 400 grams also means that the handheld transmitter microphone can be worn effortlessly for longer periods.
The Shure GLXD2+/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 also make it an interesting proposition for more advanced users who plan to use it frequently. A metal fixed receiver complete with rear-mountable antennae is available in addition to a plastic desktop receiver with front antennae and also includes a rack-mounting kit. Those looking for an easy-to-use wireless system that can be operated with up to 16 transmission paths at once can achieve this courtesy of the bodypack transmitter by utilising the 2.4GHz and 5.8GHz frequency bands simultaneously. Alternatively, up to eleven transmitter/receiver combinations can be operated at the same time using just the 2.4GHz setting.
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 GLXD2+/Beta58 handheld transmitter not only delivers a bright midrange, making it the perfect choice for singers and speakers, but also ensures a minimised proximity effect courtesy of its weakened bass range, resulting in a microphone that packs quite a punch soundwise, even under adverse acoustic conditions. Singers in Top-40 bands and solo entertainers who perform for lengthy periods can also look forward to up to 12 hours of operation on a single battery charge, and the battery level indicator on one of the compatible receivers makes it easy to see when the next recharge is needed. Even if only one transmitter can be used with a compatible receiver at once, it is still possible to couple it with two transmitters simultaneously, allowing the user to switch between different microphone transmitters much more quickly. In this case, an ID, which allows the user to distinguish between the transmitters, is made available and can be read off the receiver.
