The left and right output channel mixers are shown in Figure 43. These mixers allow the AUX inputs,
the ADC bypass and the DAC left and right channels to be combined as desired. This allows a mono
mix of the DAC channels to be done as well as mixing in external line-in from the IN3.
The IN3L/IN3R and PGA inputs have individual volume control from -15dB to +6dB. The DAC
channel volumes can be adjusted in the digital domain if required. The outputs of these mixers are
routed to OUT1L/OUT1R or OUT2L/OUT2R. They can also optionally be routed to the OUT3 and
OUT4 mixers.
