Audio Modes
Balanced: Provide a full-scale output of
24 dBu. This mode is intended for professional
balanced applications.
Unbalanced: Intended to drive the unbalanced
inputs of consumer amplifiers, in which case
one side of the line must be grounded.
Outputs are to drive line level inputs.
Not intended to drive speakers
directly.
Audio Sources
The channels routed to the line outputs may
include:
Embedded audio source
AES audio source
Analog audio source
