I-Vital Specs Specific kanye Izici
Kunezici ezine eziyinhloko ezingathinta ukufaneleka kweyunithi yekhanda ukuze kusetshenziswe kunoma yimuphi uhlelo lomsindo wezimoto. Kuye ngesimo esithile, ezinye zalezi zici zizobaluleka kakhulu kunabanye. Akukho myalelo othize, yiwo:
- isabelomali
- amandla
- izici
- i-aesthetics
Noma ubani osebenza kwisabelomali uzofuna ukuthola i-head unit ehlangabezana noma edlula izidingo zakhe kwezinye izigaba ngaphandle kokuphula ibhange. Kodwa-ke, umuntu ozama ukwakha uhlelo oluzwakalayo lomsindo ngesikhathi esisodwa kuzoba nezinto eziza kuqala. Ake sibheke ngokwengeziwe ngokujulile izimfanelo ezahlukene okufanele uzibuke ku-unit unit enkulu.
I-Fact Factor
Ngaphambi kokuba inqubo yokukhetha i-head unit ingaqala, kubalulekile ukuhlola idatha yemoto ezoyisebenzisela kuyo. Iningi lezinhloko zekhanda lihambisana nezigaba ezimbili zamasayizi ezibizwa ngokuthi i-DIN eyodwa ne-DIN kabili, futhi iningi izimoto zibe nedamu elilodwa noma elilodwa le-DIN dash receptacle.
Uma i-head unit ekhona ingamamitha angu-50 ubude (50mm) ubude, ukushintshwa kufanele kuhambisane nesilinganiso esisodwa se-DIN. Uma i-unit ekhona ingamasentimitha angu-100 (100mm) ubude, khona-ke ingabe iyunithi eyodwa noma kabili yekhanda le-DIN lingasetshenziswa. Kodwa-ke, kudingekile ukuhlukanisa ukuze ufake ifoni eyodwa ye-DIN ibe yikamelo lokuphindwa kabili le-DIN.
OEM Vs. I-Aftermarket
Ukushiya iyunithi yekhanda le-OEM endaweni ngokuvamile akuwona umqondo omuhle, kodwa kukhona okunye okuhlukile. Uma i-head head ye-OEM inezici zonke ezifunayo, ukuyihlanganisa nge- amplifier nezikhulumi ze-premium zingalondoloza imali. Noma kunjalo, lokho ngokuvamile ngeke kuhlinzeke umsindo ongcono kakhulu. Ngaphandle kokuthi inyunithi yekhanda ye-OEM inemiphumela yesikhangiso, lolo hlobo lokusetha luzoholela ekuphambukeni komsindo. Uma i-unit unit yekhanda yokuqala inemiphumela yangaphambili, noma uma imoto ine-amp amp, ishiya endaweni ingasebenza kahle.
Imithombo Yomsindo
Imithombo yomsindo oyinhloko yezinhloko zomsindo izoxhomeka ekuthandweni komuntu siqu ngoba wonke umuntu unelabhulali yemidiya eyenziwe ngamanani ahlukene wekhasethi, ama-CD, ama-MP3, namanye amafayela omculo wedijithali . Ngokuya ngalokho onakho eqoqweni lakho, ungase ufune ukubheka i-head unit engadlala:
- Amathempulethi e-cassette
- Ama-disc compact
- Ama-DVD
- Ama-disc-Blu-ray
Ezinye izingxenye zekhanda ze-DIN ezimbili zingadlala zombili ama-cassette nama-CD, futhi zikhona nezinyunithi zekhanda ezifaka ukulawula kwe-CD. Amanye amayunithi akwazi ukudlala amafayela womculo wedijithali, kufaka phakathi i-MP3, i-AAC, i-WMA, nabanye, okushiswe kumaCD, futhi kukhona nabashintshi be-CD abahambisana nefomu ye-DIN yefomu.
Uma ngabe wonke umtapo wolwazi wakho we-media usezingeni eliphezulu, ungase ufune ukubheka i-unit unit engenamandla. Igama elithi "elingenalutho" libonisa ukuthi ayikho izingxenye ezihambayo ngaphakathi kwalezi zingxenye zamakhanda. Njengoba bengakwazi ukudlala ama-CD noma amakhasethi, ungadlala umculo kusuka ezintanjeni ze-USB, amakhadi we-SD, noma amashayela angaphakathi angakapheli.
Ngaphezu kwalokho, izinyunithi zekhanda ngokuvamile zihlanganisa uhlobo oluthile lwe-tuner yomsakazo. Ngaphandle komsakazo we-AM / FM oyinhloko amanyunithi amaningi ekhanda anikeza, ungase ufune ukufuna:
Ukusetshenziswa
Iyunithi yekhanda enezici ezinhle futhi ibukeke ishaja ngeke ibe lula ukuyisebenzisa. Njengoba i-head unit iyisikhungo somyalo ozoyisebenzisa ukulawula uhlelo lwakho lonke lomsindo nsuku zonke, kulula ukusebenzisa. Lesi sici kulula ukugcizelela, kodwa futhi kuyimbangela ehamba phambili yokuzisola komthengi. Ngisho noma uthenga i-head unit inthanethi, kuwumqondo omuhle ukubuka imodeli yokubonisa esitolo sendawo ukuze uzame ukulawula.
Amandla
Ama-audiophiles, amandla angenye yezinto ezibaluleke kakhulu ezicatshangelwayo ekwenzeni uhlelo lokulalelwayo lwemoto. Noma kunjalo, ngokujwayelekile amandla e-amplifier eyenza abantu bajabule. Izinhlelo ezinhle zezwi zithinta izikrini ze-unit unit ezakhelwe ngaphakathi ne-RCA.
Kunezizathu ezimbili zokucubungula amandla ekhanda lesikhulu. Uma ukwakha uhlelo lokulalelwayo lwemoto ngesabelomali, futhi ukuthola umsindo ongcono kakhulu akubalulekile kuwe, ngakho kubalulekile ukuthola inhloko yekhanda enekhono elikhipha amandla. Kungenzeka futhi ukwakha uhlelo lokulalelwayo lwemoto, lapho uzofuna khona ukuthola ikhanda eliyinhloko elinemiphumela emihle ye-amp amp kanye ne-RCA. Lokho kuzokuvumela ukuthi ujabulele umsindo ozwakalayo ngaphandle kwe-bat, futhi uzokwazi ukulahla i-amplifier enhle ku-mix kamuva.
Indlela yokunquma amandla we-amp built-in ukubuka inani le- RMS . I-RMS ibhekisela ezimpandeni-kusho-square, futhi le nombolo empeleni inenjongo ngendlela yokukhangisa okufana "namandla okuphakama" kanye "namandla omculo" akukhona. Noma kunjalo, ama-head units ngokuvamile akakwazi ukukhipha inani eligcwele le-RMS kuzo zonke iziteshi ezine zesiphakamisi ngesikhathi esisodwa. Kuthatha amandla amaningi ukukhiqiza ama-bass kunamanye ama-frequencies, ngakho-ke ungalindela ukuphazamiseka okuthile ngaphandle kokuthi usebenzise i-pass pass crossover.
Izici ezengeziwe
Kuye ngesistimu yomsindo ozama ukwakha, kunezinye izici eziningi okufanele uzibuke. Amanye alawa abalulekile ekuthuthukisweni kwesistimu, njengemiphumela ye-preamp, nabanye bazosiza ngokushesha.
