Overview
 
The Shure GLXD14R+ is a digital wireless lavalier microphone system that offers reliable hands-free audio with outstanding sound quality in a package that's simple to use, even if you've never operated a wireless system before. Shure's next-generation technology handles the set up for you, automatically scanning both the 2.4 and 5.8 GHz frequency ranges to seek out the best possible digital transmission channel to ensure dependable performance for your performances, broadcasts, interviews, and events at a typical range of up to 100' indoors and 65' outside.
 
Bodypack Transmitter and Omnidirectional Lavalier Mic
 
This version of the GLXD14+ is configured with a bodypack transmitter and a WL93 omni lavalier microphone, a tiny lav that's easily concealed in the talent's clothing while still delivering broadcast-quality speech and vocals.
The omnidirectional polar pattern picks up sound from all around the capsule, helping to supply consistent speech levels, even when the talent isn't speaking directly toward the microphone; a windscreen is provided.
The mic plugs into the TA4F connector on the rugged, metal GLXD1+ bodypack transmitter, which offers an ergonomic design and a comfortable fit with a convenient on/off switch that can be operated by feel.
Up to 12 hours of operation are supplied by the included SB904 rechargeable lithium-ion battery. A red and green LED indicator shows sync and battery statuses at a glance.

Half-Rack Receiver for Installation
 
This configuration includes a metal half-rack receiver with front-panel charging for the SB904 battery and an easy-to-read display that shows pertinent information.
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.

Reliable Dual-Band Technology
 
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 to the main transmission frequency, the GLX-D+ is constantly monitoring 2 extra "backup frequencies”, so if the system detects interference, it will switch to one of the backups automatically without the user even knowing.
Besides the additional spectrum, there are other benefits 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 GLXD+FM 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.
Intelligent Battery Rechargeability
 
The GLXD1+ bodypack transmitter runs on an intelligent SB904 rechargeable lithium-ion battery (included).
The battery provides up to 12 hours of continuous use on a full charge.
The transmitter automatically powers off after approximately 1 hour to conserve battery life if the signal from a linked receiver is not detected.
The SB904 battery can be recharged in the GLXDR4+ receiver's charging bay (located on the front panel). The charging bay can also be used to recharge a spare battery while the transmitter is in use.
Alternately, the SB904 can be recharged while in the bodypack transmitter with the included USB charging cable.
Just a 15-minute quick charge provides 1.5 hours of use.
The SB904's remaining battery life is displayed in hours and minutes from the receiver's front panel.
