The Shure GLXD4R+ is a single-channel digital wireless audio receiver compatible with the GLXD1+ bodypack and GLXD2+ handheld transmitters (available separately) and housed in a metal half-rack chassis with two removable rear-panel antennas. Rackmounting hardware is included, making this model ideal for installations in small venues, houses of worship, conference rooms, and event spaces. Shure's next-generation technology automatically scans 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 presentations, performances, conferences, and events at a typical operating distance of up to 100' indoors and 65' outside.
The receiver 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.
