Shure AXT400 Axient Wireless Dual Receiver 470-698 MHz

The Shure AXT400 Axient Wireless Dual Receiver (470-698 MHz model) offers professional-grade features including advanced interference detection and avoidance, seamless frequency diversity, and comprehensive remote control capabilities via the Shure Wireless Workbench software.
Core Performance Features
Interference Detection and Avoidance: The receiver automatically detects interfering signals and, when used with an AXT600 Spectrum Manager and ShowLink, can automatically or manually switch to a clear, compatible frequency without audio interruption.
Frequency Diversity: This mode ensures seamless, uninterrupted audio in challenging RF environments by receiving the same audio source on two independent frequencies simultaneously, and using the best possible signal.
Wideband Tuning: An expansive tuning bandwidth of up to 228 MHz in the specified model (470-698 MHz is the range for this specific unit, a portion of the total range the model supports), allows a single receiver to cover a vast portion of the usable RF spectrum, simplifying inventory and providing flexibility.
ShowLink™ Remote Control: When paired with a ShowLink Access Point, this feature provides comprehensive real-time remote control over all linked transmitter parameters, including gain adjustments and frequency changes, directly from the receiver's front panel or a computer.
Connectivity & Control
Networking: Dual Ethernet ports enable connection to a network for advanced monitoring and control using Shure's Wireless Workbench 6 software. The ports are Power over Ethernet (PoE) enabled for powering a ShowLink Access Point.
RF Cascade Ports: These ports allow the RF signal to be shared with up to five other receivers in the same frequency band, eliminating the need for external antenna splitters.
Audio Outputs: The unit includes transformer-balanced XLR and 1/4" analog audio outputs, which can be used simultaneously with a 24-bit AES3 digital audio output for high-quality digital signal chains.
Compatibility: The AXT400 receiver is compatible with both Shure Axient (AXT) and UHF-R series transmitters.
