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
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.
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:
