Diversity Setup
Diversity is a DSQD feature that safeguards against loss of audio signal caused by RF interference or by power loss
in a transmitter. The DSQD architecture allows three different types of diversity reception. Once chosen, the diversity
mode is shown on other screens with a link icon.

• Switched: Of the two antennas available on the DSQD, the audio automatically “switches” to the antenna receiving
the best audio quality. In this mode, there are four receivers available.

• Ratio: In this mode, two receiver channels can be “paired” as one receiver. Either Channels 1 and 2 or channels 3
and 4 can be combined into a pair. One receiver in a pair is fixed on Antenna A and the other receiver in a pair is
fixed on Antenna B. The DSQD automatically uses whichever receiver’s RF signal quality is better.
