Volume Lock
The volume lock discrete input is used to disable the volume controls of the portable electronic device.
When this input is Active Low (i.e. grounded when active, and open otherwise) the volume up, volume
down, and mute features are disabled. All other features of the Flight Stream remain functional. Each input
presents a load of greater than 10 kΩ.
Table 6-6. Discrete Inputs
An asterisk (*) following a signal name denotes the signal is an Active-Low, requiring a ground to activate.
If there is no asterisk, the signal is an Active-High.
