AD4D AD4D Dual Channel Receiver
Assigning Transmitters to Transmitter Slots
Each receiver channel contains eight transmitter slots to control the RF signals
passed by the receiver. Transmitters can be assigned to the channel slots
or "registered" with the receiver.
For added protection from interference, the receiver will issue a warning or
block signals from any transmitters that aren't registered.
To assign a transmitter to a receiver channel:
1. From the Channel menu: Transmitter(s)>Transmitter Slots
2. Use the control wheel to scroll to an available transmitter slot. If the slot
is occupied, syncing will overwrite the existing transmitter.
3. Align the transmitter with the IR sync window and press SYNC.
When the sync is complete, the transmitter will be assigned to the slot. The
transmitter will remain assigned to the slot until it is unlinked. To remove a
transmitter from a slot, use the control wheel to select the slot, and then press
UNLINK.
Tip: For quick access, the slots can be accessed from the channel menu by
selecting the F4 function button.
Interference Management
In the event of signal degradation, Interference Management technology
provides options to move to a clean, compatible frequency, either manually
or automatically.
Respond to an alert by manually selecting a new frequency, or allow the
Spectrum Manager or Wireless Workbench to automatically deploy a backup
frequency the instant interference is detected.
Tip: To dismiss a interference alert, select the affected channel, and then
select Dismiss.
Configuring Interference Management
Interference Management can be configured for each channel individually.
Setting the Detection Mode
The Mode setting determines how the receiver will switch to a clear frequency
in the event of interference
1. Select a channel and navigate to: Advanced>Interference Management
12/21
2. Choose one of the following modes:
⁃ Manual: Select a frequency manually when interference occurs
⁃ Automatic: Allow the receiver to automatically select a new frequency.
Unregistered Transmitter Action
The unregistered transmitter option determines how the receiver reacts to
the presence of unregistered transmitters, which can be a potential source
of interference.
From the Interference Management menu, choose one of the following op-
tions:
• Allow: The receiver will pass audio from the unregistered transmitter
• Warn: The receiver will display a warning when an unregistered transmit-
ter is detected
• Block: The receiver treat the unregistered transmitter as interference and
will block the audio
Frequency Server
The frequency server option allows you to assign a networked Spectrum
Manager as a server for clear frequencies in the event of interference.
1. From the Interference Management menu, select Freq. Server
2. Press the control wheel to enable editing, and then select a Spectrum
Manager from your network.
3. Press ENTER to save.
Channel Quality Meter
The home screen displays a channel quality meter, providing a visual indicator
of the signal-to-noise ratio of the RF signal. When the RF signal is strong
with a low level of noise, all five segments of the meter are filled or the
number 5 is displayed.
If the noise ratio increases, the fewer segments are displayed or the quality
number drops. Low levels of channel quality provide an early warning of po-
tential problems, allowing you to switch to a clear frequency.

Frequency Diversity
Frequency Diversity enables seamless, uninterrupted audio for mission-critical
applications. Frequency Diversity works by transmitting the audio on two in-
dependent frequencies from an ADX2FD Frequency Diversity handheld
transmitter or from two AD/ADX series transmitters.
When operated in Frequency Diversity mode, the receiver uses two frequen-
cies to provide a single channel of audio. If one frequency experiences inter-
ference, the audio from the other frequency is used to prevent dropouts or
interruption of the audio.
Using Frequency Diversity in conjunction with Interference Detection provides
an additional layer of protection for the audio signal.
1. From the channel menu: Advanced>Frequency Diversity.
2. Choose one of the following frequency diversity modes:
⁃ Combining: For use with a single ADX2FD handheld transmitter
⁃ Selection: For use with a pair of AD1 or ADX1 series transmitters
3. Press ENTER to save.
4. Perform an IR sync between the receiver and the transmitters.
