Kickback Series Combos9ENGLISHFRANÇAISDEUTSCHEESPAÑOLITALIANOThe Hartke Kickback Series Bass Amplifier gives you control over shaping the sound ofyour bass, using a process called equalization. To understand how this works, it’s import-ant to know that every naturally occurring sound consists of a broad range of pitches, orfrequencies, combined together in a unique way. This blend is what gives every soundits distinctive tonal color. The Kickback Series EQ controls allow you to alter a sound byboosting or attenuating specific frequency areas - they operate much like the bass andtreble controls on stereo, but with much greater precision.The Kickback KB12 and Kickback KB15offer three bands of equalization. Each EQknob, labeled Bass, Midrange, and Treble,affects a different frequency area of the au-dio. We carefully selected these frequencyareas because they have maximum impacton bass guitar signals. The Bass and Treblecontrols are shelving EQs, which provideboost when the control is moved clockwisefrom the center or cut when the control is moved counterclockwise from the center. TheMid EQ control is a peaking EQ. As the Mid control is turned clockwise the frequency areais boosted; as it is turned counterclockwise the frequency area is attenuated.In many instances, the best way to deal with equalization is to think in terms of whichfrequency areas you need to attenuate, as opposed to which ones you need to boost. Beaware that boosting a frequency area also has the effect of boosting the overall signal;specifically, too much Low EQ boost can actually cause overload distortion or even harmthe connected speaker.Using EqualizationBass TrebleMidrange
