that pair. In this screen, the RF Signal Strength meter
is split with each side showing the RF signal strength of
one of the members of the diversity pair. (In the previ-
ous figure, the RF signal strength for Receiver Module
5 is the left half of the meter and the RF signal strength
for Receiver Mocule 6 is the right half.)

Frequency Diversity

Frequency Diversity mode uses two transmitters si-
multaneously carrying identical audio (the transmitter
microphones are placed right next to each other), and
the VR Field System performs a ratio blend of the audio
output from the associated receiver modules to protect
against dropouts. Another benefit of this mode is the
system avoids a transmitter that is signaling the end of
its battery life.
Frequency Diversity pairs two transmitters (of the same
make and model) with two adjacent receiver modules
(1-2, 3-4 or 5-6). Each transmitter/receiver in the pair

is tuned to a different frequency. The RF signal level at
each receiver is monitored and the audio is blended in a
manner similar to ratio diversity.

screen, the RF Signal Strength meter is split with each

In Frequency Diversity mode, the compatibility mode,
noise reduction, pilot tone bypass and output level are
all matched. For example, setting the compatibility
mode to Digital Hybrid in one receiver of the pair auto-

matically sets the other receiver to the same compatibil-

operating frequency are set independently.
Frequency Diversity has two modes of operation: nor-
mal mode and test mode. Test mode is automatically
activated when the DivMode Setup Screen is active and
Frequency Diversity is selected. In this mode, the audio
is always blended exactly 50/50 allowing a true null to
be achieved when the INVT function is activated. When
exiting this setup screen, normal mode is activated and
the blending ratio depends on the RF signal strengths.
The INVT control is used during system setup to match
the audio from each transmitter/receiver module pair.
Pressing the front panel Function button inverts the
audio from the second half of the selected receiver pair.
This control can be used to balance transmitter audio
output levels and to allow transmitters having opposing
output audio phases to be used together in this mode.
Note: Each Receiver Module in the Frequency
Diversity pair must be tuned independently to
match the associated transmitter. This is done
by selecting the receiver using the front panel
Receiver Select Button to open its Receiver Detail
Screen, then rotating the MENU/SELECT control
to the desired frequency.

LockSet Setup Screen

The LockSet function is used to prevent inadvertent
changes to the VR Field System setup. LockSet is
accessed from the Top Menu. The MENU/SELECT
control is used to toggle between the "NOT LOCKED"
and "LOCKED" states.
