Amplifiers peli le kanaleng: entsprechen motheo, mefuta e le tlhophiso
Ka stereos tse fapa-fapaneng tsa stereo seholisa hahiloeng ka sesebediswa. Leha ho le joalo, ho ke ho hlokahala hore ho sebelisa kopanetsoe-le kanaleng ke tlohang libui e phahameng matla le ho behela ba matla haholo utloahalla amplifiers. Amplifiers ka amanang ho bobeli libuela-hōle le ho metjha e tloaelehileng ka tsela borokho. Ba tšehetsa tlase impedance mojaro. Ka ba molemo ho ya sehlooho ke bokhoni ba ho boloka tlhakantsuke le phetoho.
Ha beha ho seholisa tsa stereo hase kamehla boleng ba modumo o molemo. U ka rarolla bothata bona ka ho kenya molumo lab.
