|By default, the Icon 800's embedded audio processor controls the following:
- Acoustic echo canceller (AEC)
- Noise reduction
- Automatic gain control
To use an external controller, turn Integrated Audio on.
When this option is on, the following conditions apply:
- The volume buttons on your phone and main screen are unavailable.
- Active Mic defaults to Line In. Microphones connected to line in audio inputs are always on.
- DVI audio inputs are on until you stop them at their source.
NOTE: The Integrated Audio preference is available for the Icon 600 from the command line.
