AXT400 Dual Channel Receiver
The AXT400 Dual Channel Receiver combines advanced analog and digital technology to deliver exceptional RF and audio performance. The receiver features ShowLink™
Remote Control for real-time transmitter adjustments, Frequency Diversity mode for seamless dual-frequency operation, and Interference Detection & Avoidance. It offers up
to 228 MHz of wideband tuning and supports Axient and UHF-R series transmitters. Connectivity options include transformer balanced audio outputs, AES3 digital audio out-
put, RF Cascade ports and dual Ethernet ports for networked control and monitoring via Shure Wireless Workbench
®
6 software.
Features
ShowLink™ Remote Control
The AXT400 offers 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. All functions of the Linked transmitter including gain adjustments and synchronized frequency changes can be controlled 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 an interfering analog or digital signal. When a potential interference source is detected, a warning mes-
sage 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
Frequency Diversity provides seamless audio in environments where there is a risk of dropouts or interference by using transmission from a single audio source on two in-
dependent radio frequencies. In Frequency Diversity mode, the AXT400 Receiver continuously analyzes signal quality and uses both signals to provide optimized audio on a
single channel. In the case of RF interference on one frequency the receiver automatically uses the other frequency, delivering clean, uninterrupted audio.
Wideband Tuning
Up to 228 MHz tuning bandwidth accommodates multiple transmitter bands, providing flexibility and simplifying receiver inventories. A single receiver can cover the entire US
UHF TV band.
Networking
The AXT400 Receiver shares information with other system components via Ethernet, enabling advanced features such as remote control of transmitters and management
using WWB 6 software. The receiver has two RJ45 Ethernet ports capable of 10/100 Mbps network speeds. The Ethernet ports are power over Ethernet (PoE) enabled, which
can be used to supply power to a ShowLink Access Point. To verify the network is correctly configured, the list of network-ready devices can be identified using the Find All
utility in the front panel menu.
Groups and Channels
The receiver includes a wide selection of frequency Groups which allow 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
The cascade ports share RF signal with up to 5 receivers within the same frequency band. RF cascade allows antenna signal to be conveniently distributed for up to 10 chan-
nels without using splitters or distribution amplifiers.
Compatible Transmitters
The receiver is compatible with the following Shure transmitters:
