Izici Zomkhiqizo:
Lesi siqinisi samandla senziwe ngezinto ezisezingeni eliphezulu futhi sinokusebenza okuhle kakhulu nekhwalithi. Ifanele ukudlala umculo, amatiyetha asekhaya, nezinye izindawo.
Izinketho ezahlukahlukene zokufaka nokuphumayo: Ineziteshi ezi-2 (4) zokufaka kanye nokuphuma kwezikrini zezipikha ezi-2 (4). Isekela okokufaka okuhlukahlukene kwesignali yomsindo futhi inikeza ukuphuma komsindo okuzinzile, okusezingeni eliphezulu.
Izici eziyingqayizivele: Inkomba yokucindezela iphuzu eliphezulu, izilungiselelo zeswishi yokukhetha ukuzwela, izindlela ezintathu zokusebenza, njll. Lezi zici eziyingqayizivele zihlangabezana nezimo nezidingo ezahlukene, zinikeza umuzwa wokusebenzisa oguquguqukayo futhi owenziwe ngezifiso.
Ukusebenza okuhle kakhulu nokwethembeka okuzinzile: Inemisebenzi efana nokuqalisa kahle lapho kuvulwa ugesi, i-DC, ukushisa ngokweqile, ukulayisha ngokweqile, nokuvikela okufushane. Isebenzisa ubuchwepheshe obuthuthukisiwe bokubanda komoya ukuqinisekisa ukuthi imishini ingasebenza ngokuzinzile ngaphansi kwezimo ezahlukahlukene.
Ukufakwa nokusebenza okulula: Izinyathelo zokufaka ezilula nezicacile nemiyalelo yokusebenza kwenza kube lula kubasebenzisi ukuqala ngokushesha, ngaphandle kwesidingo sokusebenza okuyinkimbinkimbi namakhono ochwepheshe.
Ngokufingqa, amaphuzu avelele kakhulu wokuthengisa ama-amplifier ochungechunge lwe-D dual-channel (quad-channel) atholakala ekusebenzeni kwawo ezingeni elichwepheshile, ukucushwa okuhlukahlukene kokufaka nokuphumayo, izici ezihlukile, ukusebenza okuhle kakhulu nokwethembeka okuzinzile, kanye nokufakwa okulula nokusebenza.
Ipharamitha yomkhiqizo:
Imodeli: OBT-DM20
Amandla okuphumayo (1 KHz, THD < 1%, zonke iziteshi zishayelwa):
8Ω i-stereo / 250W * 2 / 300W * 2 / 400W * 2
4Ω i-stereo / 320W * 2 / 480W * 2 / 560W * 2
2Ω stereo / 450W * 2 / 670W * 2 / 780W * 2
Uhlelo lokuvikela ukuphepha: Ukuvikelwa kwe-DC; ukuvikelwa okufushane; uhlelo oluzwelayo lokuphatha ukushisa ngokweqile; ukuvikelwa kokushisa ngokweqile; ukuvikelwa kokulayisha ngokweqile kokufaka; ukuvikelwa kokulayisha ngokweqile kokuphumayo; ukuvikelwa kokuqalisa kahle; ukuvikelwa komkhawulo we-amplitude kungafinyelela ku-10V
