Setting Input Signals - Polycom SoundStructure C16 Design Manual

Virtual Channels Muted
If the Mics group is unmuted and the Zone 1 Mics group is muted, the mute status of the Zone 1 Mics
displays the mute status and the Mics group displays a mixed mute state because some microphones in the
group are still muted but others are unmuted. The mixed mute state is shown as a cross hatched bar in the
mute button.
Notice in the above figure that the gain for the microphone inputs in the Mics group displays as 43 with
dashed lines around it indicates that some - but not all - of the microphones have a gain of 43 dB. In this
example, the wireless microphone has a different gain value. The group displays a dashed line if all the
values are not the same for the members in the group. In the above figure, 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.
Note: Changing Virtual Channels and Groups
Changing virtual channel group settings changes all the settings for the virtual
channels that are a part of the virtual channel group and generate command
acknowledgments 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, the
virtual channel group setting does not set automatically to the common value and consequently are no
command acknowledgment that the virtual channel group has that common value. For instance, if all
microphones in the Zone 1 group are muted individually, the Zone 1 group does not acknowledge that the
group is muted. However, if the Zone 1 group is muted, Zone 1 group acknowledges that the group and all
the members of the group are in a muted state.
Note: Individually Changing Members in a Virtual Channel Group
Changing the settings of all members in the group individually to a common value
does not cause the virtual channel group to show that common value.

Setting Input Signals

The settings applied to input signals depend on the type of virtual channel created from that physical input.
For example, there are different controls if the signal is a microphone input, line level input, a stereo virtual
channel, a signal generator, or a telco input.
