Which of the following is NOT a selection for the Channel VU Meters?

The selection labeled as VU Output is not recognized as an option for the Channel VU Meters. The VU Meters serve the purpose of displaying the audio levels within a channel, and typically, they come in different variations such as VU Small and VU Large, which correspond to different display sizes. VU Direct generally refers to a measurement that reflects the signal level without any alteration.

In the context of audio signal processing, the term 'output' is typically associated with the final signal after processing rather than a dedicated VU Meter selection. This means VU Output does not fit within the conventional categories of meter selections, which focus on monitoring levels rather than output characteristics. Hence, this option does not belong within the list of standard selections for VU Meters in the given system.
