2.2.1.1 Line Inputs

For the line input configuration, shown in Figure 3-4, the PCM1841-Q1 captures the audio signal provided through terminals J1 (IN1), J2 (IN2), J3 (IN3), and J4 (IN4). The input accepted in this mode is a differential, 2VRMS, full-scale audio signal. Single-ended inputs are not supported by the PCM1841-Q1 device and the inputs must be AC coupled.
