Segment Number
Frequency Diversity
Frequency Diversity enables seamless, uninterrupted audio for mission-critical applications. Frequency Diversity works by
transmitting the audio on two independent 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 frequencies to provide a single channel of audio. If one fre
quency experiences interference, 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 sig
nal.
From the channel menu: Advanced > Frequency Diversity.
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
Press ENTER to save.
Perform an IR sync between the receiver and the transmitters.
Antenna Bias
All antenna ports provide a DC bias to power active antennas. Set the DC power to off when using passive (nonpowered) an
tennas.
To turn off the antenna bias:
From the Device Configuration menu: Device RF > Antenna Bias
Press the control wheel to enable editing, and then select Off
Tip: The Antenna Bias screen displays the current draw for each individual antenna and the total current draw for all antennas.
