Overview
The Shure AD4Q-US is a 4-channel wireless receiver housed in a rugged, single-rack unit complete with cable and mounting accessories. Part of the Axient Digital system, it delivers mission-critical signal stability and clear, transparent sound for professional productions that demand flawless execution. The AD4Q-US operates in a single 166-MHz ultrawide bandwidth that encompasses the entire usable UHF range from 470 to 636 MHz. Quadversity mode allows placement of two pairs of antennas in different zones or doubling antennas in one zone. The Dante Cue and Dante Browse features enable high-fidelity headphone monitoring from any connected Dante-enabled device.
- Wide tuning range up to 184MHz
- True digital diversity reception per channel for drop-out resistance
- Networked control with Wireless Workbench software and ShurePlus Channels iOS app
