System information

AXT400 Dual Channel Receiver
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 IR 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 RF 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
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 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.
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. The receiver has two RJ45 Ethernet ports capable
of 10/100 Mbps network speeds. The Ethernet ports
provide Power over Ethernet (PoE), 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 pre-programmed
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 signals with up to 5 receivers
within the same frequency band. RF cascade allows
antenna signal to be conveniently distributed for up to 10
channels without using splitters or distribution amplifiers.
