Note: If encryption has been set from off to on, the receiver will generate a new encryption key and must be IR synced to the transmitter to share the new key.

System Set Up

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 1: Scanning to Find the Best Channel

The Scan function automatically selects the best available receiver channel.

Navigate to the Scan menu option.
Press enter to start the scan.
When the scan is complete, the channel will appear on the display.

The channel screen displaying the number 3

Network Scan

The Network Scan feature automates frequency assignment by using a single receiver to scan and deploy frequencies to all networked receiver within the same frequency band.

Network Scanning and Frequency Deployment

Connect receivers to an active Ethernet network. All receivers must be on the same subnet.
Prior to performing a network scan, turn on all receivers and allow 60 seconds for all receivers to join the network.
Choose a group or custom group for deployment on the receiver that will be used to initiate the network scan.
To start a network scan, press the menu button and navigate to the network scan menu. Press enter.
When the scan is complete, the displays of receivers waiting for frequencies will flash.
Press enter to deploy the frequencies or press menu to cancel the deployment.
The front panel LEDs on each receiver will blink when a deployed frequency has been assigned.

Note: Full frequency deployment may not occur if the number of receivers in the network exceeds the number of available frequencies in the selected group. Try another group or rescan after turning off unused receivers.

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.

Turn on the transmitter.
Press the sync button on the receiver. The red ir LED will blink indicating that sync mode is active.
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.
A success message 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.

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:

Navigate to the group setting.
Use the arrow buttons to scroll through the groups.
Press enter to select a group.
Next, use the arrow buttons to select a channel.
Press enter to save.

The group screen set to 2 and the channel screen set to 3

Manual Frequency Selection

Manual frequency selection can be used instead of groups and channels to set the transmitter and receiver to a specific frequency. For example, an audio channel can be created by setting the receiver and transmitter to same frequency.

Setting the Receiver Frequency

Press menu to navigate to the frequency setting option.
Use the arrow buttons to adjust the frequency. Press and hold for faster scrolling.
Press enter to save.

Linking Two Transmitters to a Receiver

Linking two transmitters to a receiver offers the flexibility to provide a performer with either a handheld or bodypack transmitter to meet their preference. For performances requiring instrument changes, two bodypack transmitters can be linked to a single receiver.

Note: Only turn on and operate one transmitter at a time to prevent interference between the transmitters.

Syncing the Transmitters to the Receiver

Both transmitters must be individually linked to the receiver by performing an IR Sync.

Turn on the first transmitter and perform an IR Sync with the receiver.
Perform a sound check and adjust the transmitter gain if necessary. When finished, turn off the transmitter.
Turn on the second transmitter and perform an IR Sync with the receiver.
Test the transmitter at performance conditions and adjust the transmitter gain if necessary. When finished, turn off the transmitter.

Matching Audio Levels with Mic Offset

When linking two transmitters to a receiver, there may be a difference in volume levels between microphones or instruments. If this occurs, use mic offset to match the audio levels and eliminate audible volume differences between transmitters. If using a single transmitter, set the mic offset to 0 dB.

Turn on the first transmitter and perform a sound check to test the audio level. Turn off the transmitter when finished.
Turn on the second transmitter and perform a sound check to test the audio level.
If there is an audible difference in the sound level between the transmitters, navigate to the Mic Offset menu on the transmitter to increase or decrease the mic offset in real time to match the audio levels.

The mic offset screen set to +6 dB

Radio Frequency (RF) Settings

Setting the Transmitter RF Power

The transmitter offers two RF power settings which determine the transmitter range.

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

Insert an Ethernet cable in the Ethernet port on the rear of the receiver.
Connect the cable to a computer or router.
The port LEDs on the receiver will illuminate to indicate network connectivity and network traffic.

Automatic IP Addressing

Enable a DHCP service on the server or use a DHCP enabled router.
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:

Start WWB6 software and use Inventory view to see devices connected to the network.
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.
From a WINDOWS/MAC command prompt, type ‘ping IPADDRESS’ of the device (e.g. "ping 192.168.1.100").
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.
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.

Network settings entered manually must be valid and conform to IP protocols to ensure proper network communication.

Receiver Menu

IP addresses and subnet addresses contain 4 groups of numbers. Each group can contain up to 3 digits. A decimal point separates each group.

When setting an IP address or subnet address, each of the 4 groups must be edited individually. The following diagram shows how the groups are mapped to the receiver display:

An IP address with numbers calling out each group; The IP menu with numbers caling out each part

Press menu while holding the enter button to access the advanced menu.
Press the menu button to navigate to the IP menu.
Use the arrow buttons to set the mode to St (static) and press enter.
Use the arrow buttons to edit the first group. Press enter to save and continue to the next group.
Use the arrow buttons and enter button to edit the remaining 3 groups.
When group 4 has been edited, the display will show the subnet mask menu. Use the arrow buttons to scroll and select a preset value for each of the subnet mask groups.
When finished, press enter to save settings.

Note: To restore automatic DHCP IP addressing, enter the IP menu and select AU (automatic). The Network Reset menu option can also be used to restore DHCP addressing.

Custom Group IR Sync

When using Custom Groups, always perform an IR sync from the Custom Groups menu in the receiver to ensure accurate display of group and channel information. See Custom Groups topic for additional details.

Radio Frequency (RF)

The blue RF LED will illuminate when a linked transmitter is within range of the receiver. Measure the transmitter range before a performance to avoid operating beyond the specified transmitter range.

The RF meter bars indicate amount of RF power being received. This signal could be from the transmitter, or it could be from an interfering source, such as a television broadcast. If the meter shows a signal level when the transmitter is off, then that channel may have interference. Check the surrounding area for sources of interference or change the receiver to a clear frequency.

A red RF LED indicates RF overload. Avoid operating multiple systems in close proximity.

Frequency Compatibility

Perform a Scan and Sync to ensure the transmitter and receiver are set to the same channel or frequency
Look at the label on the transmitter and receiver to make sure they are in the same band (G50, J50, L50, etc...).

Reducing Interference

Perform a scan to find the best open frequency. Perform an IR sync to transfer the settings to the transmitter.
For multiple systems, make sure that each receiver is assigned to a unique channel. Interference will occur if two transmitters are set to the same channel.
Maintain a line of sight between transmitter and receiver antennas.
Move receiver antennas away from metal objects or other sources of RF interference (such as CD players, computers, digital effects, network switches, network cables and Personal Stereo Monitor (PSM) wireless systems).
Eliminate RF overload (see below).

Increasing Range

Increase transmitter RF power level to Hi
Use an active directional antenna, antenna distribution system, or other antenna accessory to increase RF range

Eliminating RF Overload

If the RF OL icon appears on the RF meter, try the following:

Reduce the transmitter RF power level from Hi to Lo
Move the transmitter further away from the receiver—at least 6 m (20 ft)
If you are using active antennas, reduce antenna or amplifier gain.
Use omnidirectional antennas
