OUTPUT MIXERS

Left and right analogue mixers allow the DAC output and analogue bypass paths to be mixed.

Programmable attenuation and mute is available on the analogue bypass paths from LINPUT3,

RINPUT3 and from the input boost mixers as shown in Figure 13. A mono mix of left and right output

mixers is also available on OUT3.

Figure 13 Output Mixer Path

Left and right mixers are enabled by the LOMIX and ROMIX register bits. The mono mixer is enabled

by OUT3 register bit, which also enables the OUT3 driver.

to change volume levels of these paths during playback.
