Setting Input Source
Each input channel may be configured to receive signal from a unique source.
To set an input’s source:

2. Press the Headphone encoder to display the list of available input sources.
Options include:
◦ OFF – Use to deactivate an input without having to change trim.
◦ MIC – Use for dynamic microphones or mic-level sources.
◦ MIC-PH – Use for microphones requiring phantom power. Provides 48V or
12V phantom power.
◦ LINE – Use for analog line level sources.
◦ LINE-PH – Use for phantom-powered condenser microphones.
Provides 48V or 12V phantom power, but at a line-level gain
range. Useful in high sound-pressure-level environments.
◦ AES42 – Use for digital AES42 (Mode 1) microphones.
◦ AES3 – Use for a digital AES3 source.
3. Turn the Headphone encoder to select an input source.
