Shure AD4Q 2025 - black

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.

Interference Detection and Avoidance
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.

Pristine Digital Sound and Secure TransmissionTransparent Sound: A flat, 20Hz to 20kHz frequency response provides accurate audio reproduction.

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.
