Isixhobo esahlula imiqondiso yesandi ebuthathaka ibe ziifrequensi ezahlukeneyo, ezibekwe phambi kwe-power amplifier. Emva kokwahlulwa, ii-power amplifier ezizimeleyo zisetyenziselwa ukukhulisa isignali nganye yebhendi yesandi kwaye ziyithumele kwiyunithi yesithethi ehambelanayo. Kulula ukuyilungisa, kunciphisa ukulahleka kwamandla kunye nokuphazamiseka phakathi kweeyunithi zesithethi. Oku kunciphisa ukulahleka kwesignali kwaye kuphucula umgangatho wesandi. Kodwa le ndlela ifuna ii-power amplifier ezizimeleyo kwisekethe nganye, ebiza kakhulu kwaye inesakhiwo sesekethe esintsonkothileyo. Ingakumbi kwiinkqubo ezine-subwoofer ezizimeleyo, izahluli ze-frequency ze-elektroniki kufuneka zisetyenziswe ukwahlula isignali kwi-subwoofer kwaye ziyithumele kwi-subwoofer amplifier.

Iprosesa yesandi sedijithali ye-DAP-3060III ene-3 kwi-6 ngaphandle

Ukongeza, kukho isixhobo esibizwa ngokuba yi-digital audio processor kwimarike, esinokwenza imisebenzi efana ne-equalizer, i-voltage limiter, i-frequency divider, kunye ne-delayer. Emva kokuba i-analog signal output yi-analog mixer ingeniswe kwi-processor, iguqulwa ibe yi-digital signal ngesixhobo sokuguqula i-AD, icutshungulwe ize iguqulwe ibe yi-analog signal yi-DA converter ukuze idluliselwe kwi-power amplifier. Ngenxa yokusetyenziswa kwe-digital processing, uhlengahlengiso luchaneke ngakumbi kwaye inani lengxolo liphantsi. Ukongeza kwimisebenzi eyaneliswa zii-equalizers ezizimeleyo, ii-voltage limiters, ii-frequency dividers, kunye nee-delayer, ulawulo lwe-digital input gain, ulawulo lwesigaba, njl. nazo zongezwe, okwenza imisebenzi ibe namandla ngakumbi.
