If individual members of a group have different values for the same parame-
ter, such as the mute state, the value of the group parameter will be shown
with a crosshatch pattern as shown in the following figures.
If the "Mics" group is unmuted and then the "Zone 1 Mics" group is muted,
the mute status of the "Zone 1 Mics" would show the mute status and the
"Mics" group would show a mixed mute state because some microphones in
the group were still muted but others were unmuted. The mixed mute state is
shown as a cross hatched bar in the mute button.
Notice in this figure that the gain for the microphone inputs in the "Mics"
group is shown as 48 with dashed lines around it indicates that some - but not
all - of the microphones have a gain of 48 dB. In this example the wireless
microphone has a different gain value. The group will show a dashed line if
not all the values are the same for the members in the group. In the following
figure the all the members of the "Zone 1 Mics" group have 48 dB of gain, so
there are no dashed lines around the gain for the "Zone 1 Mics" group.
Changing virtual channel group settings will change all the settings for the virtual
channels that are part of the virtual channel group and generate command
acknowledgements for the virtual channel group and its virtual channels members.
If a parameter for all members of a virtual channel group is individually
changed to the same value, say one channel at a time until all channels have
the same value, the virtual channel group setting will not be set automatically
to the common value and consequently there will be no command acknowl-
edgement that the virtual channel group has that common value. For instance
if all microphones in the Zone 1 group were muted individually, there would
not be an acknowledgement from the Zone 1 group that the group was muted.
However if the Zone 1 group were muted, there would be an acknowledge-
ment for the group and all the members of the group that their state was
muted.
