Ungawakhetha kanjani ama-amplifiers nezipikha zama-bass guitar?

Ingabe i-bass guitar ibaluleke kakhulu kune-amplifier esixhuma kuyo? Lo mbuzo awuyindawo, ngoba amabhesi ekhwalithi ephansi azozwakala kabi kusikhulisa-zwi esihle, kodwa ithuluzi elihle elihlanganiswe ne-amp empofu ngeke lizwakale lilihle nalo. Kulo mhlahlandlela, sizobhekana nama-amplifiers nezipikha.

Isibani noma i-transistor?

"Isibani" - isiko lamashumi eminyaka, umsindo wakudala, ojikelezayo. Ngeshwa, ukusetshenziswa kwe-tube amplifiers kuhilela isidingo sokushintsha amashubhu ngezikhathi ezithile, okwandisa kakhulu izindleko zokusebenza zamashubhu "izithando", ezisabiza kakhulu kunezimbangi zabo. Lo mncintiswano uqukethe ama-transistor amplifiers. Umsindo awuhambisani nezikhulisamandla zamashubhu, nakuba namuhla ubuchwepheshe buhamba ngokushesha kangangokuthi onjiniyela baya ngokuya basondela ekufinyeleleni izici ze-sonic zamashubhu ngama-transistors. Ku-"transistors" awudingi ukushintsha amashubhu, futhi ngaphandle kwalokho, "izithando" ze-transistor zishibhile kunamashubhu. Isixazululo esithokozisayo ama-amplifiers ayi-hybrid, ahlanganisa i-tube preamplifier ne-transistor power amplifier. Ashibhile kunamashubhu amplifiers, kodwa asathwebula omunye womsindo "weshubhu".

Omakhelwane "Omculo".

Kufanele ucabangele iqiniso lokuthi i-amplifier yeshubhu ngayinye idinga ukuphendulwa ifike ezingeni elithile ukuze izwakale kahle. Ama-amplifiers e-Transistor awanazo izinkinga ngalokho, azwakala kahle ngisho nasezingeni eliphansi levolumu. Uma singenabo omakhelwane abadlalayo, isibonelo, icilongo noma i-saxophone, ukuhlakaza "isibani" kungaba yinkinga enkulu. Ngaphezu kwalokho, kubhebhethekiswa ukuthi amaza aphansi asakazwa kangcono kumabanga amade. Ukuhlala edolobheni, ungenza uhhafu webhulokhi uyeke ukusithanda. Singadlala ngokuthula ekhaya kusikhulisi se-solid-state esikhudlwana futhi sihlabelele emakhonsathini. Ungakwazi njalo ukukhetha i-amplifier encane ye-tube ngesipika esincane, kodwa ngeshwa kukhona "kodwa" eyodwa. Kuma-bass guitars, izipikha ezincane zizwakala zimbi kakhulu kunezinkulu ngoba azilungile ngokwanele ukuletha amaza aphansi, kodwa ngaphezulu kwalokho kamuva.

Ikhanda + ikholomu noma inhlanganisela?

I-Combo iyi-amplifier ene-laudspeaker endlini eyodwa. Inhloko iyunithi ekhulisa isignali evela ensimbini, umsebenzi wayo okuwukuletha isignali esikhulisiwe kakade kusipikha. Ikhanda nekholomu kuhlangene kuyisitaki. Izinzuzo ze-commba nakanjani ukuhamba okungcono. Ngeshwa, benza kube nzima ukufaka isipika esikhundleni, futhi ngaphandle kwalokho, ama-transistors noma amashubhu avezwa ngokuqondile kungcindezi yomsindo ophezulu. Lokhu kunomphumela omubi emsebenzini wabo ngezinga elithile. Kuma-combos amaningi kuyiqiniso ukuthi isipikha esihlukile singaxhunywa, kodwa noma sicisha esakhelwe ngaphakathi, sisaphoqeleka ukuthi sithuthe sonke isakhiwo se-combo lapho sihambisa i-amplifier kusuka endaweni kuya kwenye, kodwa kulokhu nge isipikha esihlukene. Endabeni yezitaki, sinekhanda elihambayo kanye namakholomu ahamba kancane, okuthi uma kuhlangene kube yinkinga enzima kwezokuthutha. Kodwa-ke, singakhetha isipikha esikhulukazi ngokuya ngokuthanda kwethu. Ngaphezu kwalokho, ama-transistors noma amashubhu "ekhanda" awavezwa ukucindezela komsindo, ngoba asezindlini ezihlukile kunezipikha.

Usayizi wesipika kanye nenani lamakholomu

Kuma-bass guitar, isipikha esingu-15 ”sijwayelekile. Kuyafaneleka ukunaka ukuthi isipikha esikhuluma (lokhu kusebenza futhi kusipikha esakhelwe ngaphakathi ku-combach) sifakwe i-tweeter. Ezimweni eziningi ingu-1 ”futhi itholakala kukholamu efanayo nesipika esikhulu. Akudingekile neze, kodwa ngenxa yalokho, isiginci se-bass sithola igquma eligqame kakhudlwana, okubalulekile ekugqabuleni ingxube lapho udlala ngeminwe yakho noma uphaphe, futhi ikakhulukazi nge-clang technique.

Uma isipikha esikhulu, singakwazi ukuphatha kangcono amaza aphansi. Kungakho abadlali be-bassi ngokuvamile bekhetha izipikha ezinezipikha ezingu-15 “noma 2 x 15” noma 4 x 15 “izipikha. Kwesinye isikhathi izinhlanganisela nesipikha esingu-10 nazo ziyasetshenziswa. I-15 "isipika sinikeza amabhesi amahle, futhi i-10" inesibopho sokugqekeza ebhendini ephezulu (indima efanayo idlalwa ama-tweeter akhelwe ezipikheni ezino"sipikha" esingu-15). Kwesinye isikhathi abadlali be-bass baze banqume ukuhamba ngisho no-2 x 10 “noma 4 x 10” ukuze bagcizelele impumelelo ebhendini ephezulu. I-bass ephuma lapho izoba nzima kakhulu futhi igxile kakhulu, okungenzeka ibe yinto efiselekayo ezimweni eziningi.

Kunemithetho ethile okufanele uyikhumbule lapho ukhetha amakholomu. Ngizokunikeza izindlela eziphephe kakhulu. Kukhona, yiqiniso, abanye, kodwa ake sigxile kulabo abasengozini enkulu. Uma ungaqiniseki nganoma yini, thintana nochwepheshe. Hhayi ukudlala ngogesi.

Uma kuziwa emandleni, singakhetha isipikha esilingana namandla weamplifier. Singakwazi futhi ukukhetha isipikha esinamandla aphansi kune-amplifier, kodwa-ke kufanele ukhumbule ukuthi ungaqapheli kakhulu i-amplifier, ngoba ungalimaza izikhulumi. Ngaphezu kwalokho, ungakhetha futhi isipikha esinamandla amakhulu kune-amplifier. Kulesi simo, akufanele udlule ngokweqile ngokuhlakaza i-amplifier, ukuze ungalimazi, ngoba kungenzeka ukuthi sizozama ukusebenzisa amandla aphelele wezikhulumi kuzo zonke izindleko. Uma sisebenzisa ukulinganisela, konke kufanele kuhambe kahle. Enye inothi. Isibonelo, i-amplifier enamandla angu-100 W, ukukhuluma nge-colloquially, "iletha" 200 W kusipika esingu-100 W. ngamunye wabo.

Uma kukhulunywa nge-impedance, ihluke kancane. Okokuqala udinga ukuhlola ukuthi unoxhumo oluhambisanayo noma lwe-serial. Ezimweni eziningi, kwenzeka ngokuhambisana. Ngakho-ke uma sinoxhumano oluhambisanayo ku-amplifier, isb nge-impedance engu-8 ohms, sixhuma isipikha esingu-8-ohm esisodwa. Uma unquma ukusebenzisa izikhulisa-zwi ezi-2, kufanele usebenzise izikhulisa-zwi ezingu-2 16 – ohm zesikhulisa-zwi esifanayo. Kodwa-ke, uma sinoxhumano oluwuchungechunge, siphinde sixhume isikhulumi esisodwa esingu-8-ohm ku-amplifier ene-impedance ye-8 ohms, kodwa kulapho ukufana kuphela khona. Endabeni yokuxhuma kochungechunge, amakholomu amabili angu-2-ohm angasetshenziswa ku-amplifier efanayo. Okuhlukile kungenziwa, kodwa iphutha lingaba nemiphumela emibi kakhulu. Uma ungaqiniseki ngo-4%, landela le mithetho ephephile.

Yini okufanele uyibheke?

Ama-amplifiers e-Bass ngokuvamile anesiteshi esingu-1 kuphela esihlanzekile, noma amashaneli ama-2 ahlanzekile futhi ahlanekezelwe. Uma sikhetha i-amplifier ngaphandle kwesiteshi sokuhlanekezela, sizolahlekelwa ithuba lokuthola umsindo ohlanekezelwe kuphela ngenxa ye-amplifier. Lena akuyona inkinga enkulu. Uma kunjalo, vele uthenge ukuhlanekezela kwangaphandle. Kufanele futhi unake ukulungiswa. Amanye ama-amplifiers anikezela nge-EQ enamabhendi amaningi kumabhendi ngamanye, kodwa iningi linikeza kuphela i-EQ “ye-bass – mid – treble”. Imvamisa, ama-bass amplifiers afakwe i-limiter (i-compressor esethwe ngokukhethekile), evimbela i-amplifier ekuhlanekeni okungafuneki. Ngaphezu kwalokho, ungathola i-compressor yakudala elingana namazinga evolumu phakathi kokudlala okuthambile nokunolaka. Kwesinye isikhathi ukuguquguquka kanye nemiphumela yendawo yakhelwe ngaphakathi, kepha lokhu kumane kuyizengezo futhi akuthinti umsindo oyisisekelo. Uma ufuna ukusebenzisa ukushintshashintsha kwangaphandle kanye nemiphumela ezungezile, hlola ukuthi ingabe i-amplifier ine-loop ye-FX eyakhelwe ngaphakathi. Ukushintshashintshashintsha kanye nemiphumela yendawo kusebenza kangcono nge-amp ngokusebenzisa iluphu kunaphakathi kwe-bass ne-amp. I-wah - wah, i-distortion kanye ne-compressor ihlale ixhunyiwe phakathi kwe-amplifier nensimbi. Kubaluleke kakhulu ukuhlola ukuthi i-amplifier inikeza okukhiphayo kwe-mixer. I-bass ivame ukuqoshwa ngokulandelana, futhi ngaphandle kokukhishwa okunjalo akunakwenzeka. Uma umuntu edinga okokukhipha i-headphone, kufanele futhi aqiniseke ukuthi iku-amplifier enikeziwe.

Isifinyezo

Kuyafaneleka ukuxhuma ama-bass kokuthile okubalulekile, ngoba indima ye-amplifier ekudaleni umsindo inkulu. Indaba “yesitofu” akumele ithathwe kancane uma ufuna ukuzwakala kahle.
