The LINE2L/R signals refer to the signals that travel through the analog input bypass path to the output stage.
The PGA_L/R signals refer to the outputs of the ADC PGA stages that are similarly passed around the ADC to
the output stage. Note that since both left and right channel signals are routed to all output drivers, a mono mix
of any of the stereo signals can easily be obtained by setting the volume controls of both left and right channel
signals to –6 dB and mixing them. Undesired signals can also be disconnected from the mix as well through
register control.
