Shure GLXD4+ Dual-Band Wireless Tabletop Receiver (Z3: 2.4, 5.8 GHz)

The receiver is made from durable ABS plastic and features front-panel charging for the SB904 transmitter battery (available separately) and an easy-to-read display that shows pertinent information, including the remaining transmitter battery time in hours and minutes. The system transmits audio with a flat, 20 Hz to 20 kHz frequency response and 120 dB of dynamic range, leaving the sound of your mic unaffected by the wireless components. The transmitter`s input gain can be wirelessly adjusted right from the receiver`s front panel to optimize the audio signal. The rear panel provides a balanced XLR output switchable between mic and line levels along with a balanced 1/4` Inst/Aux output.

Dual-Band Technology for Easy and Reliable Wireless Performance

• GLX-D+ Dual-Band Digital Wireless systems operate in both the 2.4 and 5.8 GHz frequency ranges, automatically scanning both to select the one that offers the higher number of clean channels.
• The previous GLX-D only worked in the 2.4 GHz range, which offers 83.5 MHz of bandwidth. By expanding into the 5.8 GHz range, the GLX-D+ provides an additional 125 MHz worth of potential open frequencies for available channels, helping to minimize dropouts and enhance reliability.
• The system offers true digital diversity, which means two antennas and two independent receiver modules work together to reduce RF signal dropouts.
• In addition, the GLX-D+ transmits on its own main frequency just like a traditional system, but it also transmits on 2 extra `backup frequencies`? at the same time. If the system detects interference on the main frequency, it will switch to one of the backups automatically without the user even knowing.
• Besides the additional spectrum, there are other benefits to in operating in the 5.8 GHz range. In general, there are fewer devices operating in this range, making the spectrum cleaner. The 2.4 GHz range is home for Bluetooth devices and other devices, including Wi-Fi routers and repeaters, security cameras, baby monitors, garage door openers, and more. Operating in this range means competing with these devices for the same space.
• GLX-D+ receivers typically allow you to run up to 4 mics simultaneously in the same space. Under ideal conditions, up to 8 systems can be used.
• If you need more mics at once, consider the GLXDR+ half-rack receiver, which offers removable antennas and can accommodate the GLXD+FMZ3/LC Frequency Manager (available separately). The frequency manager allows up to 11 mics to operate simultaneously (16 under highly optimal conditions) making it ideal for installations with multiple wireless systems.
