To apply an AV device to a channel, drag the object onto the channel in the Unit or Channel tabs. For example, to apply a Crown PCC130 tabletop microphone to Mic/Line Input 1, select the object from the AV Devices tree and drag it onto the channel.
A dialog prompts you for the distance of the microphone to the talker. Select a value and press OK to apply the object to the channel.
A microphone icon appears next to the channel, indicating that the channel is using an AV device object configuration.
Click on the microphone icon to view object properties and enter a serial number in the AV Devices Properties dialog.
