Shure AXT400 Dual Receiver: Unleash Exceptional RF and Audio Performance
The Shure AXT400 Dual Receiver combines advanced analog and digital technology for outstanding RF and audio performance. It features ShowLink Remote Control for real-time transmitter adjustments, frequency diversity mode for seamless dual-frequency operation, and Interference Detection Avoidance. With up to 228MHz of wideband tuning, it supports Axient and UHF-R series transmitters. Connectivity options include transformer balanced audio outputs, AES3 digital audio output, RF Cascade ports, and dual Ethernet ports for networked control and monitoring via Shure Wireless Workbench#174; 6 software.
Features:
- ShowLink Remote Control - Take control of your linked transmitter in real-time with the AXT400 and AXT610 ShowLink Access Point. Link Axient transmitters to each receiver channel using Infrared Sync. The ShowLink Access Point maintains 2.4 GHz wireless network communication with the transmitters and connects to the receiver over Ethernet. Adjust gain and synchronize frequency changes from the AXT400's front panel menu.
- Interference Detection and Avoidance - The AXT400 receiver can detect interfering signals during operation. When an interference source is detected, a warning message appears with frequency change options. Use the AXT600 Spectrum Manager to switch to a backup frequency manually or automatically. The Spectrum Manager monitors a compatible frequency list for optimal frequency use. With ShowLink Remote Control, the receiver and transmitter can synchronously switch to a clear frequency.
- Frequency Diversity - Enjoy seamless audio even in challenging environments with Frequency Diversity. The AXT400 Receiver analyzes signal quality and uses two independent radio frequencies for optimized audio on a single channel. In case of RF interference on one frequency, the receiver automatically switches to the other for clean, uninterrupted audio.
- Wideband Tuning - With up to 228 MHz of tuning bandwidth, the AXT400 can accommodate multiple transmitter bands, providing flexibility and simplifying receiver inventories. One receiver can cover the entire US UHF TV band.
- Networking - Share information with other system components via Ethernet for advanced features like remote transmitter control and management using WWB 6 software. The receiver has two RJ45 Ethernet ports with 10/100 Mbps network speeds and Power over Ethernet (PoE) for powering a ShowLink Access Point. Verify network configuration with the Find All utility in the front panel menu.
- Groups and Channels - The receiver offers a wide selection of frequency Groups for easy access to compatible Channels for multiple receivers. Use Channel Scan to find an open frequency within the current Group or Group Scan to find open Channels in all Groups and program compatible frequencies to other AXT400 receivers over the network.
- RF Cascade Ports - Share RF signal with up to 5 receivers within the same frequency band using the cascade ports. Distribute the antenna signal for up to 10 channels without splitters or distribution amplifiers.
- Compatible Transmitters - The receiver is compatible with the following Shure transmitters:
- AXT100 Bodypack Transmitter
- AXT200 Frequency Diversity Handheld Transmitter
- UR1 Bodypack Transmitter
- UR1H Bodypack Transmitter
- UR1M Micro-Bodypack Transmitter
- UR2 Handheld Transmitter
- MW2 Handheld Transmitter
- MW3 Handheld Transmitter
