Table 19 DAC Output Digital Mixing

AUDIO INTERFACE 2 (AIF2) OUTPUT DIGITAL MIXING

There are two digital mixers associated with the AIF2 output channels. The inputs to each AIF2 mixer

comprise signals from AIF1, AIF2 and the digital sidetone signals.

Note that the Left/Right channels of the AIF1 and AIF2 inputs can be inverted or interchanged if

required; see “Digital Audio Interface Control”.

The AIF2 output mixer controls are defined in Table 20.
