SETTING AVCU PREFERENCES
The AVCU can detect video inputs in most situations. However there are instances when manual
configuration is required. This is particularly common when running video through active
extenders, and when using video distribution amplifiers. In addition to disabling the video
detection circuitry, several other options can be changed in the AVCU preferences.
You can easily change the AVCU preferences by using the selection buttons on the front of the
AVCU:

Simultaneously hold down the - and + selection buttons, and then press the Power button.

a setting. In Figure 11, the DAC output setting is selected. The pointy brackets on the first line
