Shure AD4Q Four-channel Digital Wireless Receiver with No Accessories

Next-gen Wireless for Today's Crowded Spectrum

When you need maximum wireless performance and reliability — we're talking televised live performances, secure government installations, and similar mission-critical applications — you need Shure's Axient wireless technology. On the cutting edge of wireless technology, the Shure Axient AD4QUS 4-channel receiver can assign up to four antennas to a single channel for enhanced coverage and signal quality. Axient's Spectrum manager provides advanced frequency scanning which is displayed graphically, and can even store the data from a site survey for later use. And with Frequency Diversity mode enabled, your Shure Axient AD4QUS wireless receiver shrugs off RF interference that can cause audio interruptions in less sophisticated systems.

• Next-gen digital radio for maximum stability
• 184MHz tuning range across all receivers and transmitters
• Up to 47 active transmitters per 6MHz TV channel
• Frequency Diversity plus advanced interference detection and avoidance
• Quadversity mode for extended antenna coverage and improved RF signal-to-noise ratio

World-class sound quality and transmission security

Transmissions remain secure, thanks to AES 256-bit encryption, making Axient the perfect choice for government facilities and other sensitive installations.

Frequency diversity for maximum reliability

Axient wireless stands out in the wireless realm with its Frequency Diversity capability. It essentially allows transmission of a single source on two independent radio frequencies — Axient continuously analyzes signal quality and uses both frequencies for optimized performance. You'll experience no interruptions, dropouts, or audio artifacts caused by direct RF interference.

Advanced interference detection and avoidance

Axient's ability to detect and avoid interference is second to none. Signal interference can come from a wide range of sources, not just radio and telecom signals. The Axient AD4QUS receiver is equipped with Shure's most sensitive detection circuitry to sense signal degradation. You have your choice of automatic avoidance, or you can manually select a new frequency if you choose. When using the Axient Spectrum Manager, backup frequencies are constantly monitored, ranked, and automatically deployed in the event of signal interference.

Precision spectrum management

Axient's Spectrum Manager delivers precise wideband scanning and onboard compatible frequency calculation — backup frequency monitoring, ranking, and deployment are all available on demand too. Using the Spectrum Manager, you can capture a detailed scan of your venue (displayed graphically), and even listen to a particular signal or store the site survey data for later use.

Extremely wide 184MHz tuning range and spectral efficiency

All Axient wireless receivers and transmitters have a wide tuning range up to 184MHz for maximum spectrum coverage. And when you need to enhance your system's channel count, switch on Axient's High Density mode for a dramatic increase in channel count while maintaining maximum audio quality and reliability.

Manage your wireless gear with ShowLink Remote Control

Using Axient wireless, you'll be able to make remote adjustments to all ADX transmitter parameters in real time, using a wireless network connection between linked transmitters and receivers. At any point in the show, you'll be able to adjust transmitter settings without leaving your mix position. You can change frequencies, enable RF mute, adjust RF output power, and much more.

Wireless Workbench software and ShurePlus Channels app

Designed to give you complete control over your Axient wireless system, Shure's Wireless Workbench software provides advanced RF spectrum and Timeline plotting, frequency coordination, and live performance monitoring. You can also use your iOS device with the ShurePlus Channels app for control and system monitoring.

Networked charging for better resource management

Axient's use of smart batteries and chargers means you'll always know the status of your batteries. Not only will you be able to see how much runtime your transmitters have remaining, you'll also know the charging status of your spares. Axient batteries can deliver an impressive 9.5 hours of runtime.
