Introduction: 

The SP6015A USB AUDIO SIGNAL GENERATOR is an instrument that automatically corrects the output level of the WAV file to provide a signal necessary for the AUX input of the ST-3000 or the SG-3000.
 The WAV file is played by the built in USB Sound Card and two WAV files are allowed to be simultaneously played.
 It gets the average voltage of all signals of the selected WAV file and then automatically corrects it to be 0.68Vrms which is the voltage of the AUX input of the SX-3000.
 The selected WAV file is automatically replayed.
 This program runs only in the computers with ST-3000/SG-3000 installed to run.
