This is what the graphic EQ looks like. It's like bars, but with the bottom of the bar removed so you only see the top of each bar. Left side is 20Hz (low bass) right side is 20KHz (high treble). You choose each freq and then raise or lower it. When you boost a certain freq. the bar will move above the center line and when you reduce a certain freq the bar will drop below the center line. You really need to read the manual. Remember that once your done you need to save the EQ curve to one of the 6 presets. Also start out adjusting both left and right the same. I think you hold down a button to make the EQ stereo (no seperate left-right). This makes things go much faster and is less complicated.
