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:

Networking Receivers

The receiver uses an Ethernet connection to network with other components. For automatic network configuration, use a DHCP enabled Ethernet switch such as the Shure

AXT620 or an Ethernet router with DHCP service. Use multiple Ethernet switches to extend the network for larger installations.

Multiple device network example using the Shure AXT620

Ethernet switch

Automatic IP Addressing

1. If using a Shure AXT620 Ethernet switch, set the

DHCP switch to ON.

2. Set the IP mode to automatic for all devices (Util >

Network > Mode > Automatic)

Manual IP Addressing

1. Connect the Spectrum Manager and receivers to an

Ethernet switch.

2. Set the IP Mode to Manual for all devices:

• Menu: Util > Network

• Use the control wheel to set valid IP addresses

for all devices. Set the subnet mask for all

devices to the same value.

Troubleshooting

Use only one DHCP server per network

All devices must share the same subnet mask

All devices must have the same level of firmware

revision installed

Look for the network icons on the display of each

device:

• If the icon is not there, check the cable

connection and the LEDs on the network jack.

• If the LEDs are not on and the cable is plugged

in, replace the cable and recheck the LEDs and

network icon.

Use the Find All utility (Util > Network > Find All)

to view devices on the network:

• The Find All report lists all devices on the

network.

• Check the IP address for devices not shown in

the Find All report to ensure that they are on the

same subnet.

To check connectivity of WWB6 to the network:

1. Start WWB6 software and use Inventory view to see

devices connected to the network.

2. If not, find the IP address from one of the devices on

the network (such as an AXT400 receiver) and see if

you can ping it from the computer running WWB6.

3. From a WINDOWS/MAC command prompt, type

“ping IPADDRESS” of the device (e.g. “ping

192.168.1.100”).

4. If the ping returns success (no packet loss), then the

computer can see the device on the network. If the

ping returns failure (100% packet loss), then check

the IP address of the computer to ensure it’s on the

same subnet as the device.

5. If the pings are successful and the devices still

do not show up in the WWB6 inventory, check to

ensure all firewalls are either disabled or allow the

WWB network traffic to pass to the application.

Check that firewall settings are not blocking network

access.

Adding ShowLink for Remote Control

Adding a ShowLink Access Point enables remote control of a linked Axient transmitter from the front panel of the receiver.

Connecting a ShowLink Access Point

1. Connect the Access Point to the Ethernet port of

the receiver to establish a network connection and

supply power.

2. Position the access point within range of the

transmitter.

3. Check the transmitter and receiver menus for the

ShowLink icon, indicating that remote control is

possible.

Remote Control of Transmitters

When a linked transmitter is within range of a ShowLink

Access Point, the transmitter adjustment menu is

enabled.

1. From the home screen, select Tx > Adjust

2. Press the control wheel to highlight a parameter for

adjustment.

3. Turn the control wheel to change a parameter value.

ShowLink Test

To check the ShowLink network and connectivity,

you can use the ShowLink test mode in the AXT400

receiver:

1. Connect the AXT610 Access Point to the network.

2. Link a transmitter to the receiver by doing an IR

sync.

3. You should see the ShowLink icon on the receiver

display next to the transmitter information.

4. From the receiver menu: Util > More >

ShowLink Test.

5. Use the control wheel to highlight a transmitter to

test, and then press Start.

6. The ShowLink test will run and display a signal

strength indication.

7. If the ShowLink signal strength is low, check the an-

tenna connection on the AXT610 and the transmitter.

Frequency Diversity

Frequency Diversity uses two independent radio frequencies sent from an AXT200 handheld transmitter or from two AXT100 bodypack transmitters connected with a “Y”

cable to deliver a single uninterrupted audio channel. To optimize performance, Frequency Diversity mode must match the transmitter type.

To set Frequency Diversity mode:

1. Menu: Options > Diversity

2. Turn the control wheel to select FD-Bodypack for AXT100 bodypack transmitters or to select FD-Handheld for AXT200 handheld transmitters.

Note: For smaller systems, connect the receivers

Dual Digital Signal Processors (DSP) in the receiver analyze the RF signal for signs of interference that can degrade the audio signal. When interference is present, the

receiver screen turns red and displays one of the following warning messages:

Interference Alert

Displayed on the home screen when low-level interference is detected. Interference at this level may not be audible or may only cause a slight disruption to the audio signal.

All receiver controls can still be accessed, and If the interference is not audible, a frequency change may not be necessary.

If Interference Avoidance is set to Auto mode, a frequency change will not occur unless the strength of the interference increases to trigger an Interference

Detected message.

Interference Detected

Displayed when high-level interference likely to disrupt the audio signal is detected. The menu screen displays on-screen options for changing to a clear frequency or if

Interference Avoidance mode is set to Auto, the channel will automatically switch to a clear frequency deployed by the Spectrum Manager.

If the Interference clears without being addressed or if a frequency change is made by the Spectrum Manager, the LCD screen will return to its normal color. The detection

message indicating time elapsed since the interference occurred will remain on the screen for up to 60 minutes or until dismissed.
