dBVU – most familiar to users of typical analog audio mixers
dBFS – dB ‘Full Scale’ – the digital standard; see notes under the heading Audio
Headroom in Section 3.13
dBu – based on a voltage of 0.775 VRMS (a shy scale rarely seen in public,
supplied for completeness, comparison, and the amusement of audiophiles)
SECTION 15.4 EXTERNAL SOURCES
Columns in the first set of control groups are labeled for correspondingly numbered
Input rows on TriCaster’s rear connector panel (right-click to Rename audio inputs).
FIGURE 250
You may choose to think of these audio sources as being associated with the same-
numbered video inputs in the nearby rows on the rear connector panel.
This linkage is not strictly enforced, however. At times you may well prefer to treat
various audio sources as independent of the nominally associated video input. The
Follow (audio follows video) feature plays an important role in this context – see
Section 15.7.2.
15.4.1 CONNECTION TYPE
Individual sub-panel panels for external sources govern a group of
audio connections including variously (depending on TriCaster model)
of two XLR inputs, an AES/EBU (AES3) BNC connector, and an SDI
Embedded digital audio source.
