Pre-mkuzamawu kwa subwoofer ndi

Okonda nyimbo, kapena kuonera pa lalikulu zisudzo nsalu yotchinga pakhomo, ndithudi, ndi mmene kutenga apamwamba phokoso. Choncho, Chofunika, ndi preamplifier amasankha kuti zotsatira Kodi mwala pa zimene makhalidwe kuyang'ana posankha chipangizo audio.

Pamene kumvetsera nyimbo pa CD-player komanso amafunika mkuzamawu chifukwa chizindikiro anatumikira mlingo ofooka kwambiri. Kuthandiza mizati chikugwirizana mkuzamawu. Amatha kusintha ndi alandire chizindikiro wailesi, kulera izo voliyumu ankafuna.

Amplifiers anawagawa mitundu itatu: kuyambirira, Integrated ndi mphamvu amplifiers. Yofunika, kuti Chili zonse mu phukusi munthu, panopa ndi ambiri. zodula ndi khalidwe imatengedwa osiyana dera chipangizo wopangidwa mwa mkuzamawu mphamvu ndi preamplifier. The amplifiers ndi chubu, transistor.

Ndi Baibulo kuyambirira angathe kupatsa okonda nyimbo chenicheni phokoso ankafuna kumva - oyera ndi apamwamba, indetu moyo.

Akusankha gulu la mtengo dongosolo Mipikisano njira digito, mukhoza kukhala pa AV-purosesa. Koma kupanga chisankho mwa amplifiers, ndi bwino kupereka mmalo preamplifier amene ali phindu bwino ndalama. The purosesa amatha bwino kusintha magawo ndipo anazungulira processing. Chifukwa cha zimenezi, mukhoza kusonkhanitsa zotsatirazi dongosolo zomvetsera monga gwero (mwachitsanzo, player CD), preamplifier, mkuzamawu ndi okamba. Monga gwero angathe kutumikira player vinilu mbiri, makaseti sitimayo ndi njira zina. Paudindo preamplifier angagwiritsidwe ntchito AV-purosesa. Preamplifiers ogwira molumikizana ndi kachitidwe digito wailesi, imene kupanga nsapato amplifiers mphamvu. Zimenezi zimathandiza mwini wa zowulutsira akatswiri kupewa zolakwika pamene kuimba nyimbo kujambula ndi n'chongoletsa pafupipafupi resonances chibadidwe mu chipinda.

Pre-mkuzamawu kwa subwoofer anapereka kufunika phokoso quality, m'pofunika kuvala pakati Eq wake pafupipafupi kuyandikira kilohertz wina, ndipo midrange pansi poldetsibela.

Kusintha mawu kwa preamplifier ayenera kubweretsa izo kwa pazipita, ndipo pakhomo la mkuzamawu ndi motere osachepera. Phokoso adzakhala apamwamba khalidwe ngati linanena bungwe impedance wa preamplifier ndi poyerekeza athandizira voteji kwa mkuzamawu mphamvu. Chabwino limagwirizana amplifiers chubu sitiriyo ndi amplifiers transistor mphamvu. Mukhoza kulumikiza Baibulo kuyambirira kwa okamba amphamvu, koma kulira ndi wabwino, inu mukhoza kupeza ntchito zitsanzo situdiyo kwambiri.

Monga ulamuliro, ndi preamp atenge mbali ya Mtsogoleri, amene amalola kusintha voliyumu ndi kamvekedwe ka dongosolo wailesi, kusinthana magwero wailesi ndi kumwa chizindikiro kwa mkuzamawu mphamvu. Mosiyana ndi yamasika, ndi preamplifier pamaso.

Ngati mwasankha mkulu khalidwe preamplifier, ili njira kalasi «High Mapeto», mwachitsanzo, «Evolution», olengedwa mwa okonza German. Iwo kufika chosalowerera ndale pazipita, processing athandizira zomvetsera chizindikiro. zida ali wangwiro mchitidwe m'munsi, chizindikiro lalifupi ndi khola kudzera magetsi. Predusilistel ndi rekodi linanena bungwe kuchokera subwoofer Kanema mabokosi anaika pamwamba, zikhoza Integrated chochunira ndi ntchito zake zosiyanasiyana fonokorrektor preamplifier. Mosakayikira, chipangizo oterowo amakamba zambiri zosangalatsa mwa omvetsera awa.
