Audio Signal Encryption

The QLX-D receiver features Advanced Encryption Standard (AES-256) to protect the audio signal. When encryption is enabled, the receiver generates
a unique encryption key which is shared with a the transmitter during an IR sync. Transmitters and receivers that share an encryption key form a pro-
tected audio path, preventing unauthorized access from other receivers. To maintain security, components remain encrypted when turned off and on.
Creating an Encrypted Audio Channel
1. Press the menu button to navigate to the encryption menu, indicated by the key icon.
2. Use the arrow buttons to select an encryption option:
• on = encryption enabled
• OFF = encryption disabled
3. Press enter to save. The key icon will be shown on the receiver display.
4. 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 en-
crypt each additional transmitter.
Note: When OFF is selected from the receiver menu to disable encryption, perform an IR sync to clear the encryption key
from the transmitter and allow free reception by other receivers.
Removing Encryption
1. Press the menu button to navigate to the encryption menu.
2. Select OFF.
3. Press enter to save.
4. IR sync the transmitter and receiver to clear the encryption key from the transmitter and allow free recep-
tion by other receivers.
Note: If encryption is 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.
