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.
