To Adjust The Tone
Use the levers next to the display to set the base,
midrange and treble until you get the sound you want.
The 60 and 250 levers adjust the bass; IK is midrange;
and 3.5K and 10K control the treble.
We suggest you start with the center lever ( I K ) in the
midpoint position. Then move the others up or down
until you get the amount of bass and treble you like.
