Receiving End. The Shure GLXD4+ Dual-Band Wireless Receiver (Z3: 2.4, 5.8 GHZ) is a compact, lightweight receiver that automatically scans 2.4 and 5.8 GHz frequencies to find the best channel of transmission possible. This feature ensures dependable performance for your presentations, performances, conferences, and events at a typical range of up to 100 feet indoors and 65 feet outdoors. 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.

Designed To Last. This receiver is made from durable ABS plastic and provides an easy-to-read display that shows important information, including the remaining transmitter battery time in hours and minutes. The front panel features charging for the separately purchased SB904 transmitter battery, and 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 an XLR output switchable between mic and line levels along with a balanced 1/4" Inst/Aux output.

Dual Band Technology The GLX-D+ provides an additional 125 MHz worth of potential open frequencies for available channels compared to its predecessor, the GLXD. By adding these additional hertz, dropouts are minimized and reliability is enhanced. The system offers true digital diversity, which means two antennas and two independent receiver modules work together to reduce RF signal dropouts. This unit transmits its own main frequency, 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.
