I-AU680B iyisandisi somsindo esingenantambo esisekelwe kubuchwepheshe be-UHF (Ultra High Frequency). Inezixhumi ze-3.5mm ne-RCA L/R stereo, okwenza ukuthi idlulise umsindo wekhwalithi ye-CD ngamabanga afinyelela kumamitha angu-100. Uhlelo lusekela ukudluliswa kusuka kwodwa kuye kwabaningi, nezinye izamukeli ezingafika ku-50 zingaxhunywa kusidluliseli esisodwa. Imibhangqwana yedivayisi eyi-10 ingasebenza ngesikhathi esisodwa endaweni efanayo ngaphandle kokuphazamiseka.

Isidluliseli sifakelwe isibonisi se-frequency ukuze kube lula ukuqapha iziteshi, kanti isamukeli sihlanganisa inkinobho yokulawula ivolumu ukuze kube lula ukulungisa umsindo, okwenza i-AU680B ibe isixazululo esiguquguqukayo nesisebenziseka kalula sokusabalalisa umsindo okungenantambo.
