Important Tips for Care and Storage of Shure Rechargeable
Batteries
Proper care and storage of Shure batteries results in reliable performance and ensures a long
lifetime.
• Always store batteries and transmitters at room temperature
• Ideally, batteries should be charged to approximately 40% of capacity for long-term storage
• During storage, check batteries every 6 months and recharge to 40% of capacity as needed

Creating Audio Channels

A wireless audio channel is formed when a receiver and transmitter are tuned to the same fre-
quency. 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 occu-
pied 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.
1. Navigate to the Scan menu option.
2. Press enter to start the scan.
3. When the scan is complete, the channel will appear on the display.

Step 2: IR Sync for Automatic Transmitter Set Up
Performing an IR Sync automatically tunes the transmitter to match the receiver frequency, form-
ing 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 dis-
tance 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.
4. Next, use the arrow buttons to select a channel.
5. Press enter to save.
