15.1.1 AUDIO SPECIFICATIONS
TriCaster’s analog audio conforms to SMPTE RP-155. The maximum input/output level is +24 dBu. Nominal
input level is +4 dBu (-20dBFS), and the sample rate is 96 kHz. Levels above 0dBVU are shown in red in the
VU meters, to caution you that overly high levels can result in clipping in recordings.
Hint: An error message appears in the Status Bar above the main Program output monitor to warn you if clipping
occurs – see Section 7.3; see also Section 15.7 (Advanced Configuration) and Section 15.8.1 (Headroom Notes).
SECTION 15.2 HEADPHONES
At the extreme left side of the Audio Mixer you will observe a simple
volume control for the Headphones output. By default, headphones
connected to this stereo output jack will carry the audio signal from the
output designated Master 1 – that is, the same audio carried by outputs
marked 1a and 1b in the Audio Out group on TriCaster’s backplane.
Remember that this output is also affected source Solo switches. When Solo is enabled
for one or more sources – or outputs – only the soloed sources are sent to the connector.
(See Solo in Section 15.5.4 for more information on this feature.)
SECTION 15.3 VU METER CALIBRATION
VU (Volume Unit) meters are located right above the Volume control sliders throughout the Mixer. The
calibration of the VU meters can be changed to suit your preference.
Click the label below the Mute button in the Headphone control at left to open a small menu offering three
options as follows:
 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 3.12
 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).
