Audio Metering Display

The audio metering displays show you the audio levels in the embedded audio of the SDI video
signal. Up to 16 channels of embedded audio are de-embedded and then displayed in either
dBVU or dBFS format.
The VU meter shows average signal levels, is easy to use and very common on older equipment.
VU is calibrated to the SMPTE recommendation of a 1 kHz tone test signal set to -20 dBFS.
dBFS is essentially a meter of the overall digital audio signal and is common on modern digital
equipment.
The right hand audio scope can monitor two channels of audio, which can be selected from the
'set' drop down menu. e.g., ch 1 & 2, ch 3 & 4, etc. The audio scope presents audio in an X-Y
view so you can see audio balance issues, out of phase conditions and whether an audio track
is mono or stereo. Mono audio should appear as a single vertical "in phase" line. If the line is
horizontal, then your audio is "out of phase" and could cancel out (i.e., loss of audio) when
received by downstream equipment. Audio phase is one of the most common audio faults in
large facilities, where cables can be incorrectly connected.
