  Mix Minus

  Posted by Mike Cohen on October 14, 2010 at 9:21 pm

  My understanding is the following:

  Main audio (microphone) goes into a Mic input.
  Secondary audio (remote audio from a Tandberg audio codec, for example) goes into another input, and you turn the AUX knob for that channel to 0.
  Then you take an AUX send back to your remote audio return input, so the caller does not hear his own audio, but hears everything else on the main mix.

  Meanwhile the main mix contains all inputs, regardless of AUX settings, which goes to your record deck or PA or both.

  Have I missed anything? Obviously I am interested in the theory in this post, not going to get into specific gear being used.

  Thanks

  Hello Mike and welcome to the Cow Audio Forum.

  It’s late and I’ve had a heck of a day, but block diagram-wise, you’ve got it!

  The mix-minus goes back down a phone line to the caller, without his/her audio.

  I’m not sure how to decode your other statement: “Secondary audio (remote audio from a Tandberg audio codec, for example) goes into another input, and you turn the AUX knob for that channel to 0.”

  “Secondary audio (remote audio from a Tandberg audio codec, for example) goes into another input, and you turn the AUX knob for that channel to 0.”

  Correct. You can also use subgroups to create a mix minus, just remember: don’t assign that subgroup to the main mix bus.
