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

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.

Press the menu button to navigate to the encryption menu.

Select OFF.

Press enter to save.

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

The simplest way to create an audio channel is to use the scan function to find the best available receiver channel,

Network Scan

The Network Scan feature automates frequency assignment by using a single receiver to scan and deploy

frequencies to all networked receiver within the same frequency band.

Connect receivers to an active Ethernet network. All receivers must be on the same subnet.

Prior to performing a network scan, turn on all receivers and allow 60 seconds for all receivers to join the

network.

Choose a group or custom group for deployment on the receiver that will be used to initiate the network scan.

To start a network scan, press the menu button and navigate to the network scan menu. Press enter.

When the scan is complete, the displays of receivers waiting for frequencies will flash.

Turn on the transmitter.

Press the sync button on the receiver. The red ir LED will blink indicating that sync mode is active.

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.

Use the arrow buttons and enter button to edit the remaining 3 groups.

When group 4 has been edited, the display will show the subnet mask menu. Use the arrow buttons to scroll

and select a preset value for each of the subnet mask groups.

When finished, press enter to save settings.

When finished, select Apply.

Connecting to an External Control System

The receiver connects to external controls systems (AMX or Crestron) via Ethernet cables.

Viewing the Receiver in WWB6 Inventory

Click on the Inventory tab to view the receiver channels. Double-click on parameters to enable editing.

Tip: Clicking on the receiver icon next to the channel name flashes the front panel LEDs on the receiver for remote

identification.

Firmware is embedded software in each component that controls functionality. Periodically, new versions of firmware

are developed to incorporate additional features and enhancements.

Firmware Versioning

When updating receiver firmware, update transmitters to the same firmware version to ensure consistent operation.

The firmware version is numbered in the form of MAJOR.MINOR.PATCH (e.g., 1.2.14). At a minimum, all devices on

the network (including transmitters), must have the same MAJOR and MINOR firmware version numbers (e.g.,

1.2.x).
