Audio VU LED Indicators
These LEDs show the audio signal strength of the selected audio input sources
(embedded SDI audio, AES/EBU audio, analog 4-Channel balanced, or
2-Channel unbalanced) or the values for audio being played back during editorial.
The LEDs show a standard VU-style display, with the LEDs having the following
meanings:
Green— audio source signal level is in the “safe” area (no clipping). Vertically, the
green LEDs also show the signal strength, so you can see if the signal level is
low. Generally, it’s preferred to have the signal near the top of the green or
even occasionally peaking into the orange LEDs.
Yellow— audio source signal levels are at the peak edge of the safe area before
clipping will occur.
Red— audio source amplitude is too hot and the signal is clipping at it’s signal
peaks. You should reduce the input gain at its source (mixer or source
equipment supplying the signal).
