6.3. Mixer Analog Input
The mixer provides recording and playback of any audio sources or output mix of all sources. The
STAC9766/9767 supports the following input sources:
• Any mono or stereo source
• Mono or stereo mix of all sources
• Two-channel input with mono output reference (mic or stereo mix)
Note: All unused inputs should be tied together and connected to ground through a capacitor
(0.1 µF suggested).
Note: The MIC should be tied to ground separately through its own 0.1 µf capacitor.
6.4. Mixer Analog Output
The Mixer generates three distinct outputs:
• A stereo mix of all sources for output to the LINE_OUT
• A stereo mix of all sources for output to HP_OUT
• A mono, mic only or mix of all sources for MONO_OUT
