LQ interfaces can be setup to allow a port to be assigned to only one channel group or setup to provide multi-channel
support. See screenshot from CCM web browser below for location of this setting:

 













Multi-Channel support: Enabled/Disabled. Enable this option to use the audio source in more than one Channel.
You can assign one port to many Channels. There is no limit on the amount of Channels a port can be assigned to, but the
rules for device resource usage apply. When the unit is reaching the limits of its capacity, the user interface stops you from
assigning more ports.
When multi- channel support is activated the port icon will show the number of channels the enabled port is assigned to. 













When do I use multi-Channel ports?
An example of when to use multi-Channel ports might be if you have a program feed or stage announce that should
be heard by several teams or groups.
