Mix-minus
In audio, a mix-minus is a particular setup of a mixing console, such that the output to a certain device contains everything except the input from that device. This prevents echoes or feedback from reverberating or howling and squealing through the broadcast or sound reinforcement system.
The most common example of this is when hooking up a telephone hybrid to a console, at a radio station for example. The person on the telephone hears everything playing, including the DJ, except that the caller does not hear his or her own voice. This is also used in TV studios , so that the news anchors or actors can be in sync with the script of the TV program.
