GLXD1 Bodypack Transmitter (Z2 Band: 2400 - 2483.5 MHz)

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.

GLX-D4R Digital Wireless Multi-System Receiver

The Shure GLX-D4R Receiver is a single-channel rack-mountable receiver with removable antennas for improved audio and solid performance in multi-system installations for houses of worship, education and live music applications. The receiver features LINKFREQ Automatic Frequency Management (2.4 GHz) and an integrated battery charge port for charging a spare Shure lithium-ion battery. Up to nine compatible systems can be used in a typical setting, while a total of eleven systems can be achieved under optimum conditions when using optional GLX-D Frequency Managers.

The front panel features a high-resolution LCD screen, which displays the system status and real-time transmitter battery life in hours and minutes with an accuracy within ±15 minutes. Additional features include a remotely adjustable transmitter gain control, XLR & 1/4" output connectors, and a two-color LED charging indicator. The GLX-D4R receiver is enclosed in a rugged metal chassis and ships with two detachable antennas, a power supply, and rackmount hardware.
