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).  

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.  You can connect directly to a different external audio source in the Advanced Configuration panel (see Section 15.7).  Also, you may well prefer to treat various audio sources as independent of the nominally associated video input.  The Follow (audio follows video) features play an important role in this context – see Section 15.7.5.

15.4.1 Connection Type

Individual sub-panel panels for external sources govern a group of physical audio connections including variously (depending on TriCaster model) two XLR inputs, an AES/EBU (AES3) BNC connector, and HDMI or SDI Embedded digital audio sources.  In addition, NDI and Dante™ audio sources can be assigned to any control group.

*Note: Dante support requires an inexpensive user license from Audinate™.


Naturally, only one connection type can be active for a given audio input group at any moment. To access the Connection menu, move the cursor into the label of an input, and click the Configure (gear) button that appears just at right. The Advanced Audio Configuration panel will be shown.  

The drop-down Connection menu at the top of this pane allows the selection of one of the various sources.

  • Local physical sources are listed as IN 1 (Line, Mic, etc.), IN 2, and so on.
  • Dante sources (network audio from systems supporting this protocol from Audinate™)
  • Follow INPUT (1-n) – the default source selection; links the audio source for this control group to the same number video input.
  • NDI audio sources.

Note: Channels 1 and 2 of TriCaster’s Master and Aux 1 outputs are always sent to Dante channels 1-4.

15.4.2 Audio Hardware Options

If you choose one of the local hardware input sources, such as IN 1, you will often need to further specify which of several optional connectors grouped under that input is used to supply audio to this input.  For example, you may wish to connect to XLR connectors, or use the SDI embedded audio from the same input group on TriCaster’s chassis.

To choose this setting, click the configuration gadget (gear) shown at right beside your Connection selection in the Advanced Audio Configuration panel.  In turn, this will open the Hardware Configuration panel’s Input tab, allowing you to specify which Audio Source type you wish to use (Figure 185).

Note: On TriCaster 410, Mini SDI and Mini, only the first two inputs support analog audio.

  • Microphone – low impedance microphones and other common professional audio sources.
  • Microphone (Phantom) – microphones (typically condenser mics) requiring supplementary DC power; not supported by TriCaster Mini.
  • Line – generally consumer audio sources such as CD players, VCRs, etc.
  • AES – digital audio (4RU models only).
  • SDI Embedded (or HDMI) – digital audio embedded with digital video transmitted via a Serial Digital Interface (SDI) or HDMI connection (TriCaster Mini models).

Audio Level (dBFS)

For Microphone selections only, a Gain knob is enabled at right in the Hardware Configuration pane.  This provides additional trim for inputs, allowing you to bring input levels into a suitable operating range.
