Using Blackmagic UltraScope

Audio Metering Display

Audio Metering Display shows you the audio levels in the embedded audio of the HyperDeck Studio

Pro's video signal. 8 channels of embedded audio from your HyperDeck Studio Pro are de-embedded

and then displayed in either dBFS or VU format. The VU button switches between dBFS and VU audio

metering standards.

dBFS is essentially a meter of the overall digital audio signal and is common on modern digital equipment.

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.

The right hand audio scope can monitor two channels of audio. 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.

When monitoring stereo signals, the line of the right hand audio scope fans out to represent the difference

between the left and right audio channels. The more stereo sound contained in the audio track, the

more circular the line will appear. If the audio contains minimal stereo content, then the scope will appear

more concentrated around the vertical axis.

While spoken dialog tends to appear as a vertical line, music with plenty of stereo content will puff out.

This is because mono audio is L+R, and will display on the vertical axis, whereas stereo content is L-R,

and will display on the horizontal axis to show the stereo difference.
