ClearOne comm PRO TH20, PRO 8I, SR 1212 Room, Default Meter & Channel, Telephone Country Code

This prevents audio from being received from units above the master unit in a site. For example, you can configure a site with multiple units for a room-combining application where all units act together when three smaller rooms are combined into a larger room. When the rooms are divided again, the audio from one room will not be available in the other two rooms due to the Audio Master configuration.

In graphic above, the third unit in the network is an Audio Master with an RS-232 control device attached. Audio from the first and second units in the network does not pass beyond the second unit. Likewise the second Audio Master unit in the network does not pass audio from the unit before it. Sites can use multiple RS-232 devices, which you can connect to any unit regardless of Control Slave or Master designations.

Serial control is not affected by Audio Master or Slave designations. Global serial control of the site is maintained by the unit connected to a control device through its RS-232 port, in this case the third unit in the stack, which is also designated as the first Audio Master in the network.

NOTE: A master unit is not required for Converge/Converge Pro sites, and in most installations, all units will be slaves. Also, SNMP Control is not affected by Audio Master designations.
