The GLXD1 Bodypack Transmitter from Shure is designed to work with Shure's GLX-D series digital wireless systems. It operates on Shure's Z2 frequency band between 2400 and 2483.5 MHz on a 2.4 GHz ISM wireless band. The transmitter provides up to a 200' range of operation and features Shure's LINKFREQ automatic frequency management that allows it to automatically link to a GLX-D compatible transmitter without having to perform any setup. It includes a rechargeable battery pack that provides up to 16 hours of performance time per charge. The battery can be recharged with the included USB charger cable. A 15-minute charge can provide up to 1.5 hours of performance time. The GLXD1 has a 4-pin TA4M connector and is compatible with both lavalier microphones as well as instrument cables with a proper adapter.
