Shure The GLX-D+ Dual Band Wireless Rack System features the WA302 guitar cable and the GLXD4R+ half-rack receiver.

The Shure GLXD14R+-Z3 is a professional dual‑band digital wireless rack‑mount system designed for reliable, high‑quality, wireless audio transmission for instruments (such as guitar/bass) and performance applications. It uses Shure’s GLX‑D+ Dual Band technology that automatically scans both the 2.4 GHz and 5.8 GHz wireless bands to find the cleanest frequency channels, helping to maintain strong, interference‑resistant signal performance. The system combines a rugged metal half‑rack receiver with a lightweight bodypack transmitter and includes a guitar instrument cable (WA302) for quick setup. It offers up to 12 hours of rechargeable battery life, easy auto‑pairing, and a maximum typical operating range around 100 feet (30 m) line‑of‑sight while supporting expansion to multiple systems in the same environment.
