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 output, 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 real­time remote control of a linked transmitter when used with the AXT610 ShowLink Ac­
cess 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 inter­
ference 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 manu­
ally or automatically. The Spectrum Manager constantly monitors a compatible frequency list to ensure the best available fre­
™
quencies 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 trans­
mission from a single audio source on two independent 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 inven­
tories. 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 re­
mote 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 network­ready devices can be identified us­
ing 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 re­
ceivers. 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.
