Shure GLXD+FMZ4/LC-E – DUAL BAND Frequency Manager for Digital Wireless Systems Shure GLXD+FMZ4/LC-E is a professional frequency manager designed for managing digital wireless systems in a DUAL BAND configuration. The device serves as the central element of complex audio installations, where radio transmission stability, absence of interference, and optimal use of the available frequency spectrum are of key importance. Product Features The Shure GLXD+FMZ4/LC-E frequency manager stands out with a range of features that make it an indispensable tool in professional wireless systems: Intelligent management of up to 11 channels – the device automatically scans available bands and assigns optimal frequencies for transmitter/receiver pairs, eliminating the risk of mutual interference. DUAL BAND technology enables simultaneous operation in two frequency ranges: 2.4 GHz and 5.8 GHz, ensuring flexibility and resistance to interference. Automatic switching to backup frequencies guarantees continuous transmission even in the event of sudden interference. Powering GLXD4R+ receivers directly from the manager simplifies cabling and reduces the number of power outlets required in the rack cabinet. Professional radio spectrum management for demanding installations In the world of professional wireless audio, signal stability is just as important as quality. Shure GLXD+FMZ4/LC-E solves one of the most common problems encountered in complex installations – managing multiple wireless channels in one place without the risk of mutual interference. The manager acts as a central controller that analyzes the radio environment and intelligently assigns frequencies for each connected receiver. With the ability to connect up to 6 Shure GLXD4R+ rack receivers via RF ports, the device creates a cohesive frequency management network. If system expansion is needed, there is an option to connect up to 3 managers in a daisy-chain configuration, allowing central management of up to 16 receivers from a single controller. This solution is ideal for large installations such as theaters, conference centers, or radio stations, where the number of wireless channels exceeds the capabilities of a single device. DUAL BAND technology is another distinguishing feature of this manager. Operation in two globally license-free bands – 2.4 GHz and 5.8 GHz – means that the installation can operate legally in practically every country in the world, without the need for radio licenses. At the same time, two independent bands increase the availability of free frequencies, which is crucial in environments with high radio signal density, such as stadiums, exhibition halls, or city centers. The manager is equipped with an XLR output, which allows direct connection to a mixer or audio interface, and a USB port used for communication with receivers. The lack of a display on the enclosure is due to the fact that the device serves as a technical backend – all configurable parameters are set via the connected GLXD4R+ receivers, which have their own displays. Applications Professional wireless systems in theaters, opera houses, and concert stages Conference and congress installations in business centers and hotels Radio stations and television studios requiring multiple wireless channels Church installations and lecture halls at universities Sound equipment rental companies and event management firms Detailed Technical Specifications Number of managed channels: 11 (expandable to 16 via daisy-chain) Operating frequency type: Ultra High Frequency (UHF) Radio frequency (RF) range: 2400 – 5800 MHz Outputs: 1 × XLR Connectivity: USB Mounting type: Rack cabinet Antenna type: Removable Dimensions (W × D × H): 100 × 430 × 600 mm Enclosure material: Metal Power supply included: Yes Materials and Construction The Shure GLXD+FMZ4/LC-E frequency manager is made of a solid metal enclosure, which ensures durability and resistance to mechanical damage typical of intensively used rack installations. The device construction is designed for mounting in a standard rack cabinet, facilitating integration with existing technical infrastructure. Removable antennas allow for replacement in case of damage or adjustment to propagation conditions in a specific venue. The compact dimensions – with a width of only 100 mm – mean that the device does not take up much space in the rack, leaving room for other system components.
