OUT3 can provide a buffered midrail headphone pseudo-ground, or a left line output. It can also be
a common mode input for OUT2L/OUT2R. OUT4 can provide a buffered midrail headphone pseudo-
ground, a right line output, or a mono mix output. It can also be mixed into the input boost mixer for
recording.
