I-AU680B iyisandisi somsindo ongenantambo esisekelwe kubuchwepheshe be-UHF (Ultra High Frequency). Inezixhumi ze-3.5mm kanye ne-RCA L/R stereo, okuvumela ukudluliswa komsindo wekhwalithi ye-CD emabangeni afinyelela kumamitha angu-100. Uhlelo lusekela ukudluliswa kwelinye kuya kwabaningi, kanti inani eliphezulu lamasamukeli angu-50 lingaxhunywa kusidlulisi esisodwa. Amapheya angafika kwangu-10 wamadivayisi angasebenza ngesikhathi esisodwa endaweni efanayo ngaphandle kokuphazamiseka.

Isidlulisi sifakwe isibonisi samaza ukuze kulula ukuqapha isiteshi, kanti isamukeli sihlanganisa isiphequluli sevolumu ukuze kulula ukulungisa umsindo, okwenza i-AU680B ibe yisisombululo esiguquguqukayo nesisebenziseka kalula sokusabalalisa umsindo ongenantambo.
