Analog Line Inputs
The device includes multiple line level input options
and two analog line input programmable gain amplifiers
(PGAs, Figure 9). The line input structure supports mul-
tiple configurations including stereo single-ended inputs,
stereo differential inputs, and stereo mixed single-ended
inputs (any two per line input mixer).

Analog Line Input Mixers
The analog line input mixer allows the selection of either
single-ended or differential inputs to each line input chan-
nel (Table 21). The line A input mixer can accept single-
ended inputs from IN1, IN3, and IN5, or a differential input
from IN3 and IN4 (IN3 - IN4). The line B input mixer can
accept single-ended inputs from IN2, IN4, and IN6, or a
