Default Re: LEFT - STEREO - MONO - RIGHT Switch

1970s/1980s amplifiers did just that, connect left and right channels together. The Switch was designed around these tape recorders but Dave and Paul are correct, if you're using headphones out say on MP3 players or to be safe, insert a 1K resistor between each of the left and right inputs and their respective switches.
