Receiver Gain Adjustment
The gain control sets the overall signal level for the system. The default gain level is 12 dB and the available gain
range is -18 to 42 dB, in 1 dB increments.
Set the gain to a level where the audio LED appears green or yellow, with only the highest audio peaks causing the
LED to occasionally turn red and engage the limiter. Reduce the gain if there is audible distortion of the audio.
From the receiver home screen, use the arrow buttons to increase or decrease the gain:
A single button press adjusts the gain in 1 dB increments
Press and hold the button for larger adjustments
Test the transmitter at performance levels when adjusting the gain. Monitor the audio meter and the audio LED to
prevent overloads.
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 protected audio path, preventing
unauthorized access by other receivers. To maintain security, components remain encrypted when turned off and
on.
Creating an Encrypted Audio Channel
Press the menu button to navigate to the encryption menu, indicated by the key icon.
Use the arrow buttons to select an encryption option:
on = encryption enabled
OFF = encryption disabled
