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 “VU Meter” on page 75.
When recording to an external device, use the Output levels to help accurately monitor recorded audio.
AUDIO METER LEVELS
The DSMC 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 DBFS BAR COLOR DESCRIPTION
First line (far left border; solid) –52 dBFS Green Audio is not clipping
Second line (solid) –20 dBFS Green Audio is not clipping
Third line (dashed) –12 dBFS Yellow Audio close to clipping
Fourth line (dashed) –2 dBFS Red Audio is clipping
Fifth line (far right border; solid) 0 dBFS Red Audio is clipping (if signal exceeds –1 dBFS,
the whole bar is red)
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.
AUDIO DURING PLAYBACK
The DSMC plays all recorded channels during playback, and automatically unmutes any muted audio outputs.
To access audio settings during playback, go to Menu > Settings > Audio and select the following tabs:
