Shure AXT400 Dual Receiver - Unleash Exceptional RF and Audio Performance
The Shure AXT400 Dual Receiver combines advanced analog and digital technology to deliver 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 - Experience comprehensive real-time remote control of a linked transmitter when used with the AXT610 ShowLink Access Point. Axient transmitters can be Linked to each receiver channel using the Infrared Sync feature. The ShowLink Access Point maintains a 2.4 GHz wireless network communication with the transmitters and connects to the receiver over Ethernet. Control all functions of the Linked transmitter, including gain adjustments and synchronized frequency changes, from the front panel menu of the AXT400 in real-time.
- Interference Detection and Avoidance - During operation, the AXT400 receiver can detect the presence of interfering analog or digital signals. When a potential interference source is detected, a warning message is displayed along with options for changing frequency. When used with the AXT600 Spectrum Manager, the receiver can switch to a ¡®backup' frequency deployed by the Spectrum Manager, either manually or automatically. The Spectrum Manager constantly monitors a compatible frequency list to ensure the best available frequencies are used. With ShowLink Remote Control, the receiver and transmitter can execute a synchronized switch to a clear frequency, resolving the interference.
- Frequency Diversity - Enjoy seamless audio in environments where there is a risk of dropouts or interference. The AXT400 Receiver uses transmission from a single audio source on two independent radio frequencies to provide optimized audio on a single channel. In case of RF interference on one frequency, the receiver automatically switches to the other frequency, delivering clean, uninterrupted audio.
- Wideband Tuning - The up to 228 MHz tuning bandwidth accommodates multiple transmitter bands, offering flexibility and simplifying receiver inventories. A single receiver can cover the entire US UHF TV band.
- Networking - Share information with other system components via Ethernet for advanced features like remote control of transmitters and management using WWB 6 software. The receiver has two RJ45 Ethernet ports with 10/100 Mbps network speeds and is power over Ethernet (PoE) enabled, which can supply power to a ShowLink Access Point. Verify the network configuration using the Find All utility in the front panel menu.
- Groups and Channels - The receiver includes a wide selection of frequency Groups for easy access to compatible Channels for multiple receivers. Channel Scan finds an open frequency within the current Group. Group Scan finds the open Channels in all Groups and allows easy programming of 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 without using splitters or distribution amplifiers. Conveniently distribute the antenna signal for up to 10 channels.
- 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
