1. An electronic apparatus having a plurality of sound input channels through which audio signals are input, a plurality of individual volume controllers to individually control output volume levels of the audio signals input through the sound input channels, and a mixer to mix the audio signals provided by the individual volume controllers and to output mixed audio signals, comprising:

  • a selection part through which one of the sound input channels is selected;

    a controller controlling the individual volume controllers to make the selected sound input channel have a normal volume level and to lower the output volume levels of unselected input channels below a predetermined volume level; and

    a memory storing setup volume levels previously set up for the unselected sound input channels,wherein the controller controls the memory to store initial volume levels of the unselected sound input channels to which the output volume levels are lowered according to the selected sound input channel,wherein the controller controls the individual volume controllers to restore the output volume levels of the unselected sound input channels to the initial volume levels stored in the memory, when the selected sound input channel is released from the selection, andwherein the selection part allows a user to select the selected sound input channel.
