- Ama-A/V receiver amaningi aguqula isignali ye-bass yize enemiphumela eminingi ebonakalayo ngenxa yokulinganiselwa kwe-chip ye-DSP.
- Ukuxuba ama-subwoofers ezinhlobo ezahlukene noma osayizi ngaphandle kokulawula okuzimele kungabangela ukukhanselwa kwe-acoustic kanye nokungazwakali komsindo.
- Izakhiwo ezintsha ezisekelwe kuma-processor e-SHARC zivumela ukulingana okuzimele ngempela kwesiteshi ngasinye se-bass.
- Kungenzeka ukunqoba ukulinganiselwa kwemishini emidala usebenzisa amaprosesa angaphandle njenge-miniDSP noma isofthiwe yokulinganisa njenge-REW.
Ukusetha uhlelo lwe-bass egumbini lokuphumula akulula kangako. Kwabaningi abathanda imidlalo yaseshashalazini yasekhaya, ukuthola ama-subwoofers ahlanganiswe kahle cishe kuyikhanda elivame kakhulu , njengoba imisindo yegumbi ngalinye ingaba yinto engalindelekile, futhi ukuxhuma nje izintambo nokucindezela ukudlala akwanele ngaso sonke isikhathi.
Kunombono ophambene wokuthi ukuba nama-subwoofer amaningi aphumayo ku-A/V receiver kuqinisekisa ukulawula okuphelele kwesipikha ngasinye. Kodwa-ke, iqiniso lobuchwepheshe liwukuthi izinhlelo eziningi ziguqula isignali , okusho ukuthi yize ubona amachweba amabili angokoqobo, umamukeli uphatha izipikha zombili njengokungathi ziyiyunithi eyodwa, okunciphisa kakhulu ukusebenza kahle komsindo.
Inganekwane yokuphuma ngokuzimela kanye nenkinga ye-DSP
Ukuze siqonde ukuthi kungani abanye abamukeli bengaphathi i-bass ngokwahlukana, sidinga ukubheka ngaphakathi. Sekuyiminyaka eminingi, imikhiqizo enamandla efana neDenon neMarantz isebenzisa ama-chip e-Cirrus Logic DSP (ikakhulukazi uchungechunge lwe-CS49844) kumamodeli abo aphakathi nendawo kanye nasezingeni eliphezulu. Inkinga ukuthi le hardware icubungula i-bass ngendlela eyodwa yangaphakathi ye-mono.
Lokhu kusho ukuthi, noma ngabe umamukeli unemiphumela emibili ye-RCA noma ye-XLR, womabili athola ukulingana kanye nezihlungi ezifanayo. Ngamanye amazwi, angamakhophi aqondile womunye nomunye . Ngokuthakazelisayo, amanye amamodeli amadala ayengcono kakhulu kulokhu ngoba asebenzisa amaprosesa e-Analog Devices e-SHARC, okwavumela ukusakazwa kwedatha okuzimele—ikhono elalahleka okwesikhashana lokunciphisa izindleko zokukhiqiza.
Amamodeli athengiswa kakhulu njengeDenon AVC-X3700H noma uchungechunge oluningana lweMarantz ahlushwa yilo mkhawulo. Ngisho nemishini esezingeni eliphezulu kakhulu, njenge-AVC-X8500H, ingabonisa lokhu kuphazamiseka kwe-elekthronikhi , lapho ijika lokulungisa igumbi liphindaphindwa khona kuzo zonke iziphuphu ze-bass kungakhathaliseki ukuthi isikhulumi sibekwe kuphi.
Abasebenzisi abaningi bazizwa bedukisiwe ngoba imenyu yomamukeli ibavumela ukuthi balungise ivolumu nebanga le-subwoofer ngayinye ngokwehlukana. Akukhona ukuthi umenzi uqamba amanga, kodwa kunalokho kukhona iqhinga kusofthiwe . Izinga levolumu kanye nokubambezeleka kuyizilungiselelo ezilula zezibalo ezisetshenziswa ekugcineni kochungechunge lwesignali, ngaphambi nje kokuba isignali iphume kukhebula.
Kodwa-ke, okubaluleke kakhulu ngomsindo yizihlungi eziyinkimbinkimbi nama-crossover . Lokhu kukhiqizwa ngaphakathi kwe-DSP, futhi njengoba kunesiteshi esisodwa kuphela, womabili ama-subwoofer athola ukulungiswa okufanayo, enganaki iqiniso lokuthi ikhona elilodwa legumbi lingase libe nama-null ahlukile e-acoustic kunekhona eliphambene.
Izingozi zokuxuba ama-subwoofer ahlukene
Uma usebenzisa izikhulumi ezimbili ezifanayo, iqiniso lokuthi isignali i-cloned ngokuvamile akuyona inkinga, ngoba amagagasi ayahlangana kahle. Inkinga yangempela iphakama lapho sizama ukuhlanganisa izinhlobo ezahlukene, osayizi, noma ubuchwepheshe , njengokuhlanganisa i-subwoofer evaliwe engamasentimitha ayi-10 ne-subwoofer ye-bass reflex engamasentimitha ayi-12.
- Isikhathi esibekiwe: Umklamo ngamunye unempendulo ehlukile kanye nesivinini sokwehla.
- Ukukhanselwa kwe-acoustic: Ukusebenzisa ukulingana okufanayo kubo, kungenzeka ukuthi khansela omunye nomunye ngezikhathi ezithile, okudala izikhala lapho i-bass iphela khona.
- Ukuntuleka kwezihlungi ezithile: Ukuze amabhange ahlukene abambisane, kubalulekile ukufaka isicelo izihlungi zokusika ezizimele ezivala amaphutha e-transducer ngayinye.
Ukuziphendukela kwemvelo kwezobuchwepheshe kanye nombono omusha
Kusukela ekupheleni kuka-2022, isimo sashintsha ngenxa yokusetshenziswa kwepulatifomu ye -Analog Devices SHARC (Griffin Lite EVO) kumamodeli afana ne-Denon AVR-X3800H noma i-Marantz Cinema 50. Lo mklamo uvumela ukuphathwa kwama-subwoofers afinyelela kwamane ngokuzimela ngokuphelele.
Ngala mandla okucubungula edijithali, uhlelo lwe-Audyssey XT32 manje selungakwazi ukubala ama-curve ahlukene okulinganisa isiteshi ngasinye. Ngaphezu kwalokho, lunikeza isisekelo esidingekayo sokusebenzisa amathuluzi ochwepheshe afana ne -Dirac Live Bass Control (DLBC) , okuthuthukisa ukusebenzisana phakathi kwamaza e-bass ahlukene. Luze lwavumela nokwethulwa kwemodi ye-bass eqondisayo, yize ukusetshenziswa kwayo kwansuku zonke okusebenzayo kungaxoxwa ngakho.
Indlela yokuxazulula ukuntuleka kokuzimela kumakhompyutha amadala
Uma umamukeli wakho enomkhawulo we-Cirrus Logic, akudingeki ukuthi uwulahle. Kunezindlela zokudlula lo mkhawulo we-elekthronikhi. Enye indlela ephumelela kakhulu ukusebenzisa ihadiwe yangaphandle njenge-2x4 HD miniDSP . Uxhuma ukuphuma okukodwa okuvela kumamukeli kuya ku-miniDSP bese usuka lapho usabalalisa isignali ku-subwoofer ngayinye.
Ngokuhlanganisa lokhu nemakrofoni yokulinganisa (njenge-UMIK-1) kanye nesofthiwe ye -Multi-Sub Optimizer (MSO) , ungalinganisa futhi ubambezele isikhulumi ngasinye ngokwaso. Enye indlela engabizi kakhulu yindlela yokulinganisa ehlanganisiwe usebenzisa izinhlelo ezifana ne -REW noma i-AcoustiX . Kulesi simo, ama-subwoofers asethelwe kwimodi engathathi hlangothi, futhi kuthathwa isilinganiso sesamba sangempela esifinyelela endlebeni ukuze kusetshenziswe ukulungiswa komhlaba wonke okunciphisa ukungasebenzi kahle kwegumbi.
Umhlahlandlela Wokuxhumana: Ama-Subwoofers Asebenzayo Nangasebenzi
Kulabo abaqala phansi, kubalulekile ukuhlukanisa phakathi kwe-subwoofer esebenzayo (evele ine-amplifier yayo) kanye ne-passive (edinga amandla angaphandle). Ku- subwoofer esebenzayo , mane usebenzise ikhebula le-RCA le-coaxial kusukela ekuphumeni kwe-amplifier ethi "Sub Out" kuya ekufakweni kwe-LFE kwe-subwoofer.
Uma kwenzeka i -subwoofer engasebenzi , uxhumano lufana nolwanoma yisiphi isikhulumi, kusetshenziswa izintambo zikagesi. Uma i-amplifier inama-terminals A no-B futhi izikhulumi eziyinhloko zixhunywe ku-A, i-subwoofer ixhuma ku-B. Kunconywa ukusebenzisa izintambo ezine-cross-section enkulu ukuze uphathe kangcono amandla amaza aphansi. Ekufakweni kobungcweti noma kwe-PA, kungcono ukusebenzisa i- crossover esebenzayo ehlukanisa amaza ngaphambi kokuba afinyelele kuma-amplifier kagesi, ngaleyo ndlela kuvimbele i-amplifier ukuthi isebenze kumabanga azolahlwa kamuva yizihlungi ezingasebenzi.
Ukulawula kwangempela ukukhishwa kwe-bass kwenza umehluko omkhulu phakathi komsindo odaka kanye nokuhlangenwe nakho okujulile kwe-cinematic. Kungakhathaliseki ukuthi ukuthuthukisa ihadiwe yakho ibe yi-processors ye-SHARC, ukusebenzisa izixazululo zangaphandle njenge-miniDSP, noma ukwenza ngcono isigaba kanye nokubekwa, umgomo uwukuba yingcweti kuma-acoustic egumbi ukuze ama-subwoofers akho asebenze ngokuvumelana futhi angangqubuzani.
