4.1
Mixer Input
The mixer provides recording and playback of any audio sources or output mix of all sources. The
STAC9708/11
supports the following input sources:
any mono or stereo source
mono or stereo mix of all sources
2-channel input w/mono output reference (mic + stereo mix)
Note: any unused input pins should have a capacitor (1 uF suggested) to ground.
4.2
Mixer Output
The mixer generates two distinct outputs:
a stereo mix of all sources for output to the LINE_OUT
a stereo mix of the surround DACs for output to the DAC_OUT
a mono, mic only or mix of all sources for MONO_OUT
* Note: Mono output of stereo mix is attenuated by -6 dB .
4.3
PC Beep Implementation
PC Beep is active on power up and defaults to an unmuted state. The user should mute this input
before using any other mixer input because the PC Beep input can contribute noise to the lineout during
normal operation.
