A system for management and control of audio-related equipment. A link manager may be included in the system. The link manager may be configured to manage subscriptions to multiple other audio-related devices or control panel views. When the managed data variables change, the link manager module may notify other audio-related devices and/or control panel views of the change. In response to the notification, the other audio-related devices and/or control panels may subscribe to the audio-related device with the changed data variable, to request receipt of the updated data variable. In some examples, the link manager module may also be configured to lessen the subscription burden for a particular audio-related device.
