Audio Meter (Vu Meter) - RED EPIC-M DRAGON (Carbon Fiber) Operation Motion

EPIC/SCARLET OPERATION GUIDE

AUDIO METER (VU METER)

The Audio Meter displays at the bottom-right corner of the viewfinder, and displays either the incoming audio channels
(default), or the outgoing audio (Cam Mix, Rear Mix, and Monitor Mix). For more information, go to
page 93.
INCOMING AUDIO CHANNELS
When you select Input as the VU Meter Source, the Audio Meter displays the incoming audio channels (default). For
more information, go to "VU Meter" on
MIC-1 and MIC-2 inputs on the camera. Channel 3 and Channel 4 are greyed out unless the camera detects audio
input via the Pro I/O Module.
The channel names selected in the Audio menu determine the channel names displayed in the Audio Meter. For more
information, go to "Channel Name" on
The Audio Meter shows the incoming audio signal when a source is selected, even if the channel is not recorded.
When a channel is recorded, the channel indicator left of the Audio Meter is green.
OUTGOING AUDIO
When you select Output as the VU Meter Source, the Audio Meter displays the Cam Mix, Rear Mix, and Monitor Mix
levels. For more information, go to
When recording to an external device, use the Output levels to help accurately monitor recorded audio.
AUDIO METER LEVELS
Figure: Audio Meter
The camera updates the Audio Meter 12 times per second with the maximum signal from the last 1/12 of a second
period. The range of the Audio Meter is –52 dBFS to 0 dBFS.
The lines and colors indicate danger of clipping, as described in the table below:
Line
First line (far left border;
solid)
Second line (solid)
Third line (dashed)
Fourth line (dashed)
Fifth line (far right border;
solid)
NOTE: In the American broadcast and post production systems, –20 dBFS roughly corresponds to 0 VU and 4 dBu. In
a digital system, dBu is an approximation; the correct unit for digital audio levels is dBFS.
