5.1 MIXER INPUT
The CMI9738’s mixer input is a MUX design which offers the capability to record audio sources or
the outgoing mix of all sources. This design is more efficient to implement than an independent
input mix, and offers simple monitoring when a mix is recorded: what you hear is what you get
(WYHIWYG). The CMI9738 supports the following input sources
‹any mono or stereo source
‹mono or stereo mix of all sources
5.2 MIXER OUTPUT
The mixer generates two distinct outputs:
‹a stereo mix of all sources for output to the LINE_OUT
‹a stereo output of rear (surround) channel for REAR_OUT
