Analog Input PGA to Analog Output Mixer
The analog line input PGA and analog microphone PGA
outputs can be routed directly to any of the analog out-
put mixers. This configuration allows the analog inputs
to operate as line or microphone level input amplifiers
capable of driving headphone, speaker, receiver, or line
output loads. The analog inputs can also be mixed with
the DAC outputs to any of the available analog output
mixers. The figures in the appropriate analog input and
output sections detail the signal routing.

Analog Full-Scale Direct to ADC Mixer Inputs
The analog inputs can also be configured to accept and
route differential analog signals directly to the ADC mixers
(record path, Figure 11). By disabling and bypassing the
analog microphone and line input gain stages, this mode
provides a reduced power configuration for full-scale (up
to 1V
phone and line input configurations, this mode does not
allow the input signals to be routed directly to the analog
output mixers (playback path, Figure 31).
