Hi everyone, this is John from Zoom and I am here to show you how to create a mix-minus on the LiveTrak L-20. A mix-minus is used when you need to create
a custom mix to prevent feedback. This is essential if you are recording a Skype
call from your computer during a podcast. First connect your microphones to inputs on the L-20, then connect the headphone output of your computer to the next available input. An adapter may be necessary to make this connection. Next, connect one of the L-20’s outputs
labeled A-F to your computer’s audio input. This is necessary for the Skype caller to
hear audio from the L-20. In order to prevent feedback you will need to lower the output level of
the Skype caller on the chosen L-20 output. Now you can connect headphones for your podcast
guests and create a custom mix for each output. For more information and product updates,
