Press enter to save. The key icon will be shown on the receiver display.
Press the sync button and align the IR sync windows of the transmitter and receiver. The encryption key icon
will appear on the transmitter screen when the IR sync is complete and the encryption key has been
transferred from the receiver.
Additional transmitters can share the same encryption key with a single receiver. Perform an IR sync to encrypt
each additional transmitter.
Note: When OFF is selected to disable encryption, perform an IR sync to clear the encryption key from the
transmitter and prevent an encryption mismatch error or FAIL message.
Removing Encryption
Press the menu button to navigate to the encryption menu.
Select OFF.
Press enter to save.
IR sync the transmitter and receiver to clear the encryption key from the transmitter and prevent an
encryption key mismatch between components, indicated by a FAIL message.
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
