Abstract
An apparatus and a method for reestablishing previously established settings on the controls of an audio mixer having at least one input channel and at least one output channel. The method includes the steps of transmitting a first test signal through the at least one input channel; measuring and recording this first test signal during a first period of time at at least one output channel; transmitting a second test signal, substantially identical to the first test signal, through the at least one input channel during a second period of time; comparing this second test signal at the at least one output during the second period of time with the recorded first test signal; and altering the settings on the controls of the audio mixer in the event that the recorded first test signal is different from the second test signal of the at least one output. The apparatus includes means for transmitting the first and second test signals to the at least one input channel, means for recording the first test signal at the at least one output, means for displaying the recorded first test signal and the second test signal at the at least one output.
