Creating Audio Channels; Scan And Ir Sync; Manual Frequency Selection - Shure QLX-D Wireless System User Manual

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 to form an audio
channel
• Manual Frequency Assignment: Manually setting the receiver and transmitter to the same frequency rather than group and channel to form an
audio channel
Note: Group settings are not available in all regions - use channel settings to configure components.

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.
When the scan is complete, the receiver will automatically be set to the best available 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. Press the sync button on the receiver. The red ir LED will blink indicating that sync mode is active.
2. 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.
3. 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.
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 automati-
cally 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.

Manual Frequency Selection

Manual frequency selection is an alternative to using 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.
