The Shure AD4Q-US Axient Digital Quad-Channel Wireless System with Four ADX1 Bodypack Transmitters, Four UniPlex Cardioid Lavaliers, Showlink, and Chargers is a complete, high-performance solution designed for mission-critical productions, corporate environments, and broadcast applications. Centered around the AD4Q-US four-channel receiver, this system delivers reliable RF performance, pristine digital audio, and secure transmission for demanding, high-channel-count environments.
Operating across a 166 MHz ultrawide UHF bandwidth (470 to 636 MHz), the receiver supports expansive frequency coordination with up to 120+ simultaneous channels in standard mode, while High Density mode enables efficient operation in spectrum-constrained environments. True digital diversity reception and advanced interference detection help maintain uninterrupted audio, while AES-256 encryption ensures secure transmission for sensitive applications.
The four included ShowLink-enabled ADX1 bodypack transmitters operate in the G57 band (470 to 616 MHz) and provide flexible, user-friendly operation with automatic gain adjustment, selectable RF output power, and up to 10 hours of runtime with the supplied SB910 rechargeable batteries. Both of the included SBC240 dual-bay chargers are powered by the single included power supply and deliver network-controlled battery charging.
Combined with the four UL4 UniPlex cardioid subminiature lavalier microphones, the system delivers focused, directional voice capture optimized for speech and presentation. The 5mm capsule provides unobtrusive placement, while the cardioid polar pattern offers high gain before feedback in environments with loud sound reinforcement. A durable, paintable 1.6mm Shure Plex cable with enhanced shielding ensures long-lasting performance and resistance to interference.
An included AD610 ShowLink Wireless Access Point provides real-time remote control over the transmitters without interrupting the performer, enabling comprehensive management of transmitter parameters from the receiver or Wireless Workbench using 2.4 GHz wireless communication.
With Dante/AES67 networking, XLR and AES3 outputs, extensive remote control and monitoring capabilities via Ethernet, Wireless Workbench, and mobile app integration, this Axient Digital system is engineered to streamline your workflow while delivering dependable top-tier audio quality in the most demanding professional environments.
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.
Every feature has been stress-tested to enable seamless, uninterrupted audio in high-profile applications such as televised live performances, award shows and corporate events, the Broadway stage, secure government installations, and state-of-the-art meeting and training facilities.
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.
Other highlights include a low 2ms latency, XLR/AES3 + AES67/Dante outputs, 256-bit encryption, and HD mode for up to 47 active transmitters per 6 MHz TV channel. Axient Digital supports over 120 simultaneous channels and is compatible with AD1, ADX1, ADX1M, AD2, ADX2, and ADX2FD transmitters.
The Axient ecosystem uses multiple components that work together for advanced interference detection and avoidance. The AD4Q receiver can detect RF interference when it occurs and get a new, clean frequency from the AXT600 Spectrum Manager (available separately). Using the AD610 ShowLink Access Point (available separately), the AD4Q receiver and ADX transmitter execute a synchronized frequency change in a matter of milliseconds.
Remote Control for ADX transmitters
When it is difficult or impossible to access the transmitter, you can make instantaneous remote adjustments to your ADX transmitter settings (RF output, gain, mute, and more) via ShowLink.
Frequency Diversity Mode
In Frequency Diversity mode, two AD/ADX transmitters or a single ADX2FD transmitter can transmit two identical signals on two discreet frequencies. If the active signal degrades, the other takes over automatically, providing additional protection against dropouts. This mode uses two channels on the receiver.
Ultra-Compact ADX1M Micro Bodypack Transmitter
The ADX1M features a lightweight and ultra-compact design with an internal antenna. Comfortable to wear, it is exceptionally easy to place and conceal on talent.
Wide Dynamic Range: A dynamic range of >120 dB yields impressive signal-to-noise performance and accurate transient response.
Ultra-Low Latency: An exceptionally low 2ms latency from microphone transducer to analog output delivers a seamless, cohesive sound.
Digital Outputs: Dante and AES67 digital audio both transmit via a configurable 4-port Ethernet switch for combined control/audio or separate streams with redundancy. An AES3 output provides an additional option for pristine digital audio.
Encryption: An Advanced Encryption Standard (AES) 256-bit encrypted signal ensures that every transmission is secure and unbreachable, ideal for government facilities and other sensitive installations.
True Digital Diversity Reception: Mounting a superior defense against multipath, fading events, and other anomalies that cause RF noise, Axient Digital combines two discrete RF signals per receiver channel using a quality-based maximal-ratio-combining algorithm.
Quadversity Mode: Quadversity configures the receiver to accept four antenna inputs to maximize RF coverage and minimize the risk of dropouts and signal loss caused by interference. It also allows users to place two pairs of antennas to cover different zones. The AD4Q provides two channels of audio when configured in this mode.
High Density Mode: High Density transmission mode enables up to 47 active transmitters in one 6 MHz TV channel—all while maintaining exceptional audio quality. It is ideal for applications where many channels are needed in a confined area, transmission distances are short, and the number of available frequencies is limited.
Networked Charging for Transmitters: Intelligent, high-performance rechargeable transmitter batteries and chargers let you know how much running time is left during the show, in hours and minutes. You can also monitor the charging status of your spares.
Wireless Workbench and ShurePlus Channels App: Ethernet networking enables real-time, precision monitoring, and control of your system as well as automatic frequency coordination across multiple receivers, using Wireless Workbench and Axient Spectrum Manager software. The AD4Q is also compatible with external controllers such as AMX and Creston.
Control and monitor capabilities can be extended to an iOS mobile device via the ShurePlus Channels app, allowing you to make adjustments anywhere in the venue.
