Signal indicator chart
This section gives a feedback about the actual level of the audio
signal:
▪ In microphone input and advanced analog audio input channel,
the displayed status depends on the actual level of the input
signal and the gain setting.
▪ In the embedded audio channel, it depends on the actual level
of the input signal.
▪ In case of the advanced analog output, it depends on the actual
level of the three audio signals (mic in, advanced audio input,
embedded audio), gain settings, and the input volume settings.
Left circle refers to the left channel, right circle to the right channel.
