user interface ADB switch and controlled by the record/engineering
workstation.
The control channel has the same hardware as the playback and record
channels with the addition of a monitor for displaying the central
control user interface and keyboard and mouse for entering central

previous sections of this chapter for more information about the other versions
of AirPlay MP.
