About the Shure AXT400 Axient Dual Wireless Receiver

The Shure AXT400 is a high-density, dual-channel wireless receiver that serves as the core reception unit for the advanced Axient Digital wireless microphone ecosystem. Engineered for the most demanding professional audio applications, it delivers exceptional audio fidelity, unparalleled spectrum efficiency, and robust system control in a single 1U rack-mount chassis. Each of its two fully independent channels utilizes true diversity reception and Shure's sophisticated digital modulation to ensure a rock-solid, interference-free audio link with ultra-low latency, making it ideal for critical live broadcast, major touring productions, and large-scale installed sound where signal integrity is non-negotiable. The receiver's advanced processing preserves the full dynamic range and sonic detail of the microphone source, providing transparent wireless audio transmission.

A defining feature of the AXT400 is its deep integration into networked audio and control systems. It is equipped with dual Ethernet ports for seamless connection to Dante audio networks, allowing for digital distribution of both receiver channels over standard IT infrastructure while supporting AES67 streaming for broad interoperability. Comprehensive remote management is achieved through Shure's Wireless Workbench software, enabling frequency coordination, monitoring of RF and audio levels, adjustment of transmitter parameters, and system-wide diagnostics from a central location. This receiver also supports Axient ShowLink technology, which provides a separate 2.4 GHz control link for remote antenna selection and real-time control of compatible transmitters, further enhancing system resilience.

The unit boasts an intuitive color touchscreen interface that provides at-a-glance status information for both channels, including real-time spectrum displays, audio meters, transmitter battery life, and network health. Built with the rigorous demands of touring in mind, its robust metal chassis ensures durability. The Shure AXT400 represents the pinnacle of wireless receiver technology, combining cutting-edge digital wireless, comprehensive networking, and exhaustive system control into a single unit, empowering audio professionals to deploy and manage large-scale wireless systems with confidence in any RF environment.

FAQs about Shure AXT400 Axient Dual Wireless Receiver

What is the Shure AXT400?

The Shure AXT400 is a premium, dual-channel analog UHF wireless receiver built for mission-critical live broadcast, theater, and touring. It features advanced interference detection and avoidance circuitry, wideband tuning, and remote management within the Shure Axient ecosystem.

What frequency tuning range does the AXT400 cover?

The AXT400 provides wideband tuning across up to 228 MHz in the UHF spectrum (typically 470–698 MHz, depending on regional model). This wide tuning range significantly reduces the need to carry multiple receivers dedicated to narrow frequency bands.

How does Interference Detection and Avoidance work?

When paired with an AXT600 Spectrum Analyzer, the AXT400 continuously monitors RF conditions and can identify signal degradation before audio dropouts occur. It automatically deploys a verified, clean backup frequency within milliseconds to maintain uninterrupted audio.

What is Frequency Diversity mode?

Frequency Diversity allows the receiver to combine two independent RF transmissions carrying the identical audio signal from a single dual-carrier transmitter (such as the AXT200). If one channel suffers interference or drops out completely, the receiver seamlessly extracts the audio from the clean channel without clicks or mute events.

How does the AXT400 connect with ShowLink?

The receiver integrates over Ethernet with an AXT610 ShowLink Access Point to communicate remotely with paired transmitters. This enables sound engineers to make real-time transmitter gain, frequency, and RF power adjustments directly from the receiver front panel or networked software.

Does it support digital audio networking like Dante?

The standard AXT400 features dual transformer-isolated analog XLR outputs as well as AES3 digital audio outputs via XLR. However, it does not have native Dante or AES67 onboard; networked audio can be integrated through outboard AES3-to-Dante convertors.

How do you monitor and configure the AXT400 across a network?

The rear panel includes dual Ethernet ports for cascading and networking into Shure Wireless Workbench (WWB) software. WWB provides complete real-time RF visual plots, frequency coordination, remote parameter adjustment, and automated event logging.

What antenna connectivity and distribution features are built in?

It features standard 50-ohm BNC antenna inputs with switchable DC bias power for active antennas and in-line RF boosters (like the UA830WB). It also includes RF cascade output ports to pass antenna signals directly to up to four additional receivers without an external antenna splitter.
