The Shure AD4Q is a quad wireless receiver for the Axient Digital wireless system. It includes four discrete digital wireless receivers sharing facilities such as power in and out, RF in and out, and networking, and features Quadversity mode for extended antenna coverage and improved RF signal-to-noise.

The AD4Q Four-Channel Digital Receiver sets a new standard in spectral efficiency. Groundbreaking performance features include wide tuning, low latency, High Density (HD) mode, and Quadversity, ensuring solid performance in the most challenging RF environments. Networked control, AES3 + AES67 + Dante™ output, and signal routing options bring a new level of management and flexibility to your entire workflow.

As the new premier wireless solution in Shure’s portfolio, Axient Digital builds on the benefits of Shure’s UHF-R, ULX-D, and Axient wireless systems to create the most advanced wireless platform to date, suited for all professional productions and situations. Catering to evolving customer needs – especially in an environment of continued RF spectrum pressure – Axient Digital provides high-performance RF, exceptional audio quality, command and control, and hardware scalability.
One of the key features of the Axient Digital range is class-leading channel density, with up to 63 channels in a single TV band in high-density mode. Combined with Axient Digital’s wide frequency range, this makes large-scale wireless productions possible even in areas of high RF usage.

Features
High-Performance RF
Incorporating all of the capabilities that professional productions demand, Axient Digital is designed for maximum signal stability. It features true digital diversity with Quadversity™ receiver technology, significantly mitigating the potential for signal fades or interference that can cause dropouts. Quadversity mode allows users to place sets of diversity antennas in different zones, or double the number of antennas in a single zone, to improve RF signal-to-noise in challenging environments. High Density mode increases the maximum simultaneous system channel count from 17 to 47 per 6-MHz TV band (from 23 to 63 per 8-MHz TV band), while maintaining exceptional audio quality.

Audio Quality
Featuring pristine digital audio via Dante and AES3, Axient Digital has a 20Hz to 20 kHz range with a flat frequency response and accurate transient response. Axient Digital also boasts wide dynamic range, AES-256 encryption, and an industry leading 2ms latency from the mic transducer to the analogue output.

Command and Control
Axient Digital is compatible with Wireless Workbench® as well as the ShurePlus™ Channels App for efficient control and configuration, optimal spectrum management and frequency monitoring. The system’s Dante Cue and Dante Browse features enable high fidelity headphone monitoring of audio output from any Dante-enabled connected device. Additionally, Axient Digital provides networked charging via a suite of smart, high-performance batteries and chargers.

Hardware and Scalability
Axient Digital’s wide tuning range of up to 184 MHz for all transmitters and receivers covers an extended range of spectrum and simplifies inventory. Dual and quad receiver options, combined with a common receiver platform supporting AD and ADX transmitters, maximise user flexibility and scalability.

Wide tuning range up to 184 MHz
True digital diversity reception per channel for drop-out resistance
Networked control with Wireless Workbench software and ShurePlus Channels app
Optional DC module available to support redundant power
Quadversity mode for extended antenna coverage and improved RF signal-to-noise (AD4Q only)

RF Licensing
Our radio microphones can be set to use the Shared Frequency band Channel 38 at no cost to the hirer.

Our Shure Axient Digital systems are in Band G56 – covering the range 470-636 MHz (UK TV Channels 21 – 41) and can operate on up to 17 simultaneous frequencies in Channel 38 without intermodulation. Additional systems may require a Fixed Site License which can be obtained from OFCOM.
