SUB-MIXES AND MIX MINUS

At times you may require specially configured audio mixes, typically using one of TriCaster’s two stereo Aux audio outputs. For instance – some installations call for sending audio from one or more internal sources (such as a DDR or the Sounds player) to a secondary distribution system.

Alternatively, you may want a ‘clean’ output from one or more sources for use apart from the main primary output mix. Specialized sub-mixes of this sort 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 channel 1 of Input 1. The audio from your interviewee is routed into Channel 2. You could easily supply both to your Master bus for your program output needs, but remove channel 1 from Aux 1, and remove channel 2 from Aux 2 to provide mix minuses to send back to you different remote interviewees.

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.

Hint: TriCaster Advanced Edition provides full 4x4 matrix routing for each source, allowing for much more sophisticated mixes than the simple example above.
