Alternatively, you may want a ‘clean’ output from one or more sources for use apart from the main primary
output mix.
Specialized sub-mixes are often referred to as ‘mix-minus,’ since one or more sources are deliberately
subtracted from the main program. Mix-minus capabilities can be invaluable for productions like ‘phone-in’
shows. The remote caller needs to be able to hear the interviewer; but if you simply send the primary mix
back to him, he is forced to endure a late-arriving echo of his own voice. Needless to say, this would be
confusing and undesirable.
Suppose your interviewer is speaking into a microphone connected to Input 1. The audio from your
interviewee is routed into Input 2.
1. For Input 1, enable both the Master 1 and Master 2 switches under Routing in the Audio Configuration
panel.
2. For Input 2, enable only Master 1.
This setup gives you a clean output consisting of just the interviewer’s voice on the Master 1 bus. You can
then proceed as follows:
3. Assign Master to Output 1 in Output Configuration (Figure 204).
4. The Master 1 output connectors (1a and 1b) supply your primary audio program output for
distribution.
5. Connect TriCaster’s connectors Master 2 *connectors (1c and 1d) to your remote call hookup’s local
audio input to send the clean ‘mix minus’ back to your interviewee.
*Note that on certain TriCaster models, Master 2 and Aux 2 signals are only supplied to digital outputs.
This approach eliminates annoying echoing, feedback and the like. Meanwhile, both participants can be
heard on the main Program output. Also important, independent control and signal processing is provided
for each part of the pipeline.
15.7.5 PROCESSING
The second tab in Audio Configuration is named Processing, and likewise holds very valuable features.
E QUALIZER
The seven-band equalizer allows you to ‘shape’ sound to taste, accommodate sources with different acoustic
characteristics (say, mismatched mics), minimize feedback or roll off unwanted parts of the audio spectrum.
Enable or disable the Equalizer using the switch beside the label above its control group. The vertical sliders
attenuate or boost the tonal range centered on the frequency shown at the top.
