Cordial greeting, friend Lessin, in the equalizer in the section where it says (Input) in the Source indication the cables coming from the sound source are connected, be it a console, mixer, dvd, ipod etc, etc. any sound source , these cables enter the equalizer with RCA male connectors and the Output section of the equalizer in the Source indication, by means of male to male RCA cables it goes to the amplifier in the audio inputs indication on the red and white female RCA connectors, so This mode should work very well, since the signal will first pass through the equalizer and then reach the amplifier being able to vary its multiple frequencies, I hope I have been helpful with this opinion. Regards
