Audio loop tests can help to verify the functionality and quality of TriCaster audio inputs and outputs.
This is physically connected much like a video loop test – you connect one end of an audio cable (xlr or 1/4” depending on the unit) to the audio output, and you connect the other end into a corresponding audio input.
The difference is that if you run audio through that loop, you’ll get a horrible feedback noise, so make sure that you mute that looped input in the TriCaster audio mixer. Once you’ve done that, you can feel free to put an audio clip or video clip with audio on your program row through the DDR tab.
Once you’ve done this, you can visually inspect the greyed out bouncing VU meters to see if any audio is coming through. Remember, you will need to set the fader for the looped input to 0 db, otherwise there won’t be any sound by default, and you will need to make sure that input is set to Line.
If you need to test the looped input for sound quality, you can isocord that input by going to the record configuration and setting it to record just that input. Remember that in Advanced Edition, the audio source and the video source can be set independently. If you need this recorded clip to be in audio format only, you can set it to .mp3 by selecting the record format gear.
