Shure AD4Q Quad-Channel Receiver

Setting the standard in spectral efficiency, the ADQD from Shure is a quad-channel receiver that offers reliable wireless audio in even the most challenging environments. The ADQD is set apart by its Quadversity mode, which extends antenna coverage and improves RF signal-to-noise. Part of the Axient® Digital Wireless Systems series, this receiver is compatible with AD and ADX series transmitters.

This receiver boasts all the bells and whistles you need to optimize your audio while cutting the cord on wired sound setups. High Density Mode intensifies the coverage and maxes out the system’s channel count, while the receiver’s true digital diversity reception minimizes dropouts and a Channel Quality meter gives you real-time status of RF signal-to-noise. Networked control with Wireless Workbench® software and ShurePlus™ Channels iOS app deliver streamlined management and flexibility to your workflow. A configurable Ethernet switch lets you choose between a Dante or AES67 digital output, while the headphone jack on its front panel enables Dante™ Cue and Dante™ Browse monitoring. Other features include switchable XLR and AES3 outputs, low latency performance, wide tuning up to 184 MHz, locking AC connectors, and secure transmission via its encryption enabling.

This receiver is sold in multiple varieties, allowing you to choose accessory options as well as frequency alternatives.
