I-equalizer yebhetri isetyenziselwa ukugcina umrhumo kunye nokukhupha ibhalansi phakathi kweebhetri kwichungechunge okanye ngokuhambelana. Ngethuba lenkqubo yokusebenza kweebhetri, ngenxa yokwahlukana kwekhemikhali kunye nokushisa kweeseli zebhetri, ukuhlawulwa kunye nokukhutshwa kweebhetri ezimbini kuya kwahluka. Nokuba iiseli zingasebenzi, kuya kubakho ukungalingani phakathi kweeseli kuthotho ngenxa yamanqanaba ahlukeneyo okuzikhupha. Ngenxa yomahluko ngexesha lenkqubo yokutshaja, ibhetri enye iyakutshajwa kakhulu okanye iphume ngaphezulu ngelixa elinye ibhetri lingatshajwanga ngokupheleleyo okanye lingakhutshwa. Njengoko inkqubo yokutshaja kunye nokukhupha iphindaphindwa, lo mahluko uya kwanda ngokuthe ngcembe, ekugqibeleni ubangele ukuba ibhetri ingaphumeleli kwangaphambi kwexesha.
