Note: In digital audio systems, signal levels exceeding allowable values are ‘clipped’ (uniformly
assigned the maximum level value), inevitably entailing audible issues that cannot be corrected
later. The Audio Headroom setting In Record Configuration allows you to offset input signal levels
to provide a safety margin (see the heading Audio Headroom in Section 16.1.1). This can greatly
reduce the possibility of clipping in captured files. Beyond this, use Trim and Gain controls
judiciously to avoid over-modulation.
Compressor/Limiters in TriCaster’s Advanced Audio Configuration panels also provide powerful
tool to help avoid prevent clipping – see Section 13.4.
3.16 CONFIGURE GENLOCK
1. If the Live Desktop isn’t already open, launch a TriCaster session from Startup.
2. Access the Output Configuration panel by clicking the Configure button (gear icon) that
appears at upper-right when you move the mouse over the main Program Output
monitor on the Live Desktop.
3. Click the Genlock tab in the Output Configuration panel (Figure 29).
4. The default Reference Type in the Genlock settings is SD (Bi-level), as this is currently the
most common reference signal type. However, if you supply an HD reference signal to
the Genlock input, you may want to change the setting to HD (Tri-level).
