Creating Audio Channels
A wireless audio channel is formed when a receiver and transmitter are tuned to the same frequency. To ease setup, frequencies available to the QLX-D system are
organized into groups and channels. Each group contains a number of channels, and each channel is assigned to a specific preset frequency.
The QLX-D system provides 3 methods for tuning the receiver and transmitter to the same frequency:
• Scan and IR Sync: The receiver scans the RF spectrum for the best available frequency and an IR sync automatically tunes the transmitter to the receiver frequency
• Manual Group and Channel Assignment: Manually setting the receiver and transmitter to the same group and channel number forms an audio channel
• Manual Frequency Assignment: Manually setting the receiver and transmitter to the same frequency rather than using groups and channels forms an audio channel
Important: Before you begin a scan or frequency assignment:
• Turn off: All transmitters for system you are setting up to prevent interference with frequency scans.
• Turn on: The following potential sources of interference including other wireless systems, computers, CD players, large LED panels, and effects processors to prevent
selection of occupied frequencies.
Scan and IR Sync
The simplest way to create an audio channel is to use the scan function to find the best available receiver channel, and then use the IR sync feature to automatically tune
the transmitter to the receiver channel.

Step 2: IR Sync for Automatic Transmitter Set Up
Performing an IR Sync automatically tunes the transmitter to match the receiver frequency, forming a wireless audio channel.
1. Turn on the transmitter.
2. Press the sync button on the receiver. The red ir LED will blink indicating that sync mode is active.
3. Align the IR sync windows of the transmitter and receiver at a distance of <15 cm (6 in.). When the transmitter and receiver
are aligned, the red ir LED remains on and the sync will automatically occur.
4. sync good appears on the display when IR sync is complete. The blue rf LED will illuminate indicating that the transmitter
is within range of the receiver.
Note: If the IR sync fails, repeat the IR sync procedure, carefully maintaining alignment between the IR windows of the transmitter
and receiver.
< 15 cm (6 in.)
Manual Group and Channel Assignment
An audio channel can be manually created by simply setting the receiver and transmitter to the same group number and channel number. For example, a receiver set to
Group 2, Channel 3 and a transmitter set to Group 2, Channel 3 would form an audio channel.
Use manual group and channel configuration to assign specific groups and channels to receivers and transmitters as an alternative method to automatically creating
channels with IR sync.
Use the following steps to set the group and channel in the receiver and transmitter:
1. Navigate to the group setting.
2. Use the arrow buttons to scroll through the groups.
3. Press enter to select a group.

Networking
The receiver uses an Ethernet connection to network with other components and includes an internal DHCP client for automatic network configuration when connected to
a DHCP enabled router.
Connecting to a Network
1. Insert an Ethernet cable in the Ethernet port on the rear of the receiver.
2. Connect the cable to a computer or router.
3. The port LEDs on the receiver will illuminate to indicate network
connectivity and network traffic.
Automatic IP Addressing
1. Enable a DHCP service on the server or use a DHCP enabled router.
2. When the receiver is powered on, the DHCP server will automatically
assign an IP address to the receiver.
Tip: Use the network reset option available in the advanced features menu
to return the receiver to the default DHCP addressing mode.
Configuration Tips
• Use shielded Cat 5 or better Ethernet cables to ensure reliable network
performance
• The LEDs on the Ethernet port illuminate indicating a network connection
is active
• The network icon illuminates when the receiver detects additional Shure
devices on the network
• All components must operate on the same subnet
• Use multiple Ethernet switches to extend the network for larger
installations
Network Troubleshooting
• Use only one DHCP server per network
• All devices must share the same subnet mask
• All receivers must have the same level of firmware revision installed
• Look for the illuminated network icon on the front panel of each device:
If the icon is not illuminated, check the cable connection and the LEDs on the
Ethernet port.
If the Ethernet port LEDs are not illuminated and the cable is plugged in, replace the
cable and recheck the LEDs and network icon.
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 a
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 communicate
with the device on the network. If the ping returns failure (100% packet loss), then
verify that the IP address of the computer is on the same subnet as the receiver.
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.
Setting the IP Address and Subnet Mask Manually
IP addresses and subnet masks can be manually set from the advanced menu in the receiver or from the monitor panel in Wireless Workbench 6.
