Kusankha chokulitsa pamakina anu omvera

Poyang'ana koyamba, zingawoneke kuti njira yosankha amplifier m'galimoto kwa okamba kapena subwoofer sikophweka. Koma kukhala ndi malangizo achidule "Momwe mungasankhire amplifier" sikungayambitse mavuto. Cholinga cha amplifier pamawu omvera ndikutenga siginecha yotsika ndikuyisintha kukhala siginecha yapamwamba kuti iyendetse wokamba nkhani.

Zitha kusiyana ndi kuchuluka kwa njira zokulitsa, mphamvu ndi mtengo. Ma amplifiers awiri ndi anayi ndi omwe akufunika kwambiri pakati pa oyendetsa galimoto. Ndipo tsopano tiyeni tiyankhe funso mmene kusankha amplifier mu galimoto mwatsatanetsatane.

Maphunziro a Amplifier Galimoto

Choyamba, ndikufuna kunena za makalasi amplifier, pakadali pano pali ambiri, koma tikambirana ziwiri zazikulu zomwe zimapezeka kwambiri pamakina omvera agalimoto. Ngati muli ndi chidwi ndi mutuwu mwatsatanetsatane, kumapeto kwa nkhaniyi pali kanema yomwe ikukamba za magulu onse a auto amplifiers omwe akupezeka tsopano.

• Class AB amplifier. Ma amplifiers awa ali ndi mawu abwino kwambiri, okhala ndi kulumikizana koyenera amakhala odalirika komanso okhazikika. Ngati amplifier ya kalasi ya AB ili ndi mphamvu zambiri, ndiye kuti ili ndi miyeso yonse, zokulitsa izi zimakhala ndi mphamvu zochepa za 50-60%, i.e. ngati ma Watts 100 amadyetsedwa. mphamvu, ndiye kuti ma watts 50-60 adzafika kwa okamba. Mphamvu zina zonse zimangosinthidwa kukhala kutentha. Ndizosatheka kukhazikitsa amplifiers a kalasi AB pamalo otsekedwa, apo ayi, nyengo yotentha, imatha kulowa chitetezo.
• Class D amplifier (zowonjezera digito). Kwenikweni, kalasi ya D imapezeka mu ma monoblocks (ma amplifiers a njira imodzi), koma palinso njira zinayi ndi ziwiri zolumikizira mawu. Amplifier iyi ili ndi zabwino zambiri. Poyerekeza ndi gulu la AB, ndi mphamvu yomweyo, ili ndi miyeso yaying'ono kwambiri. Kuchita bwino kwa amplifierswa kumatha kufika 90%, sikumatenthetsa. D kalasi ikhoza kugwira ntchito mokhazikika pansi pa ohmic load yochepa. Chilichonse chikanakhala bwino, koma khalidwe la mawu a amplifiers ndi lotsika kwa gulu la AB.

Timamaliza gawoli ndi mawu omaliza. Ngati mukuthamangitsa zomveka bwino (SQ), ndiye kuti zingakhale zolondola kugwiritsa ntchito amplifiers a kalasi AB. Ngati mukufuna kupanga makina okweza kwambiri, ndiye kuti ndibwino kusankha ma amplifiers a Class D.

Chiwerengero cha mayendedwe amplifier.

Mfundo yotsatira yofunikira ndi chiwerengero cha mayendedwe amplifier, zimatengera zomwe mungalumikizane nazo. Zonse ndi zophweka apa, koma tiyeni tiwone bwinobwino:

         

• Ma amplifiers a single-channel, amatchedwanso monoblocks, amapangidwa kuti agwirizane ndi subwoofers, nthawi zambiri amakhala ndi kalasi D komanso kuthekera kogwira ntchito mopanda kukana. Zosintha (zosefera) zimapangidwira subwoofer, i.e. ngati mulumikiza cholankhulira chosavuta ku monoblock, chidzaberekanso mabasi omwe alipo.

 

• Ma amplifiers anjira ziwiri, momwe mungaganizire, mutha kulumikiza oyankhula angapo. Komanso ma amplifiers ambiri anjira ziwiri amatha kugwira ntchito munjira yolumikizidwa. Apa ndi pamene subwoofer imagwirizanitsidwa ndi njira ziwiri. Ma amplifierswa ali ndi zoikamo zapadziko lonse (zosefera), mwachitsanzo, ali ndi chosinthira cha HPF, mawonekedwewa amatulutsa ma frequency apamwamba kwambiri, ndipo posinthira ku fyuluta ya LPF, amplifier imatulutsa ma frequency otsika (kuyika uku ndikofunikira pa subwoofer).
• Ngati mumvetsetsa kuti amplifier yamagulu awiri ndi chiyani, ndiye kuti chirichonse chiri chophweka ndi njira zinayi, izi ndi ziwiri zokulitsa njira ziwiri, i.e. mungathe kugwirizanitsa oyankhula anayi kwa izo, kapena oyankhula 2 ndi subwoofer, nthawi zambiri ma subwoofers awiri ali. olumikizidwa, koma sitikulimbikitsa kuchita izi. Amplifier idzatentha kwambiri ndipo m'tsogolomu ikhoza kukhala yosagwiritsidwa ntchito.
  
  Ma amplifiers atatu ndi asanu ndi osowa kwambiri. Chilichonse chiri chophweka apa, mukhoza kugwirizanitsa oyankhula awiri ndi subwoofer ku amplifier yamakanema atatu, okamba 4 ndi subwoofer kwa amplifier asanu. Ali ndi zosefera zonse zosinthira zida zolumikizidwa kwa iwo, koma monga lamulo, mphamvu ya amplifiers ndi yaying'ono.

Pomaliza, ndikufuna kunena zotsatirazi. Ngati ndinu watsopano ku audio yamagalimoto ndipo mukufuna kupeza mawu apamwamba, omveka bwino, tikukulangizani kuti musankhe amplifier yanjira zinayi. Ndi iyo, mutha kulumikiza oyankhula akutsogolo ndi subwoofer yongolankhula. Izi zidzakupatsani kutsogolo kwamphamvu, mothandizidwa ndi ulalo wa subwoofer.

Mphamvu ya amplifier.

Mphamvu ndi imodzi mwazinthu zofunika kwambiri. Choyamba, tiyeni tiwone kuti pali kusiyana kotani pakati pa ovotera ndi mphamvu yayikulu. Chotsatiracho, monga lamulo, chimasonyezedwa pa thupi la amplifier, sichikugwirizana ndi zenizeni ndipo chimagwiritsidwa ntchito ngati chiphaso cha promo. Mukamagula, muyenera kulabadira mphamvu yovotera (RMS). Mutha kuwona chidziwitsochi m'malangizo, ngati wokamba nkhani amadziwika, mutha kupeza mawonekedwe pa intaneti.

Tsopano mawu ochepa momwe mungasankhire mphamvu ya amplifier ndi okamba. Mukufuna kudziwa zambiri za kusankha olankhula? Werengani nkhani yakuti "momwe mungasankhire ma acoustics agalimoto". Okamba magalimoto amakhalanso ndi mphamvu zovotera, mu malangizo omwe amatchulidwa kuti RMS. Ndiye kuti, ngati ma acoustics ali ndi mphamvu yovotera ma Watts 70. Ndiye mphamvu mwadzina wa amplifier ayenera kukhala ofanana, kuchokera 55 mpaka 85 Watts. Chitsanzo chachiwiri, ndi amplifier yamtundu wanji yomwe ikufunika pa subwoofer? Ngati tili ndi subwoofer yokhala ndi mphamvu yovotera (RMS) ya 300 watts. Mphamvu ya amplifier iyenera kukhala 250-350 Watts.

Mapeto a gawo. Mphamvu zambiri ndizabwino, koma simuyenera kuzithamangitsa, chifukwa pali ma amplifiers omwe ali ndi mphamvu zochepa, ndipo amasewera bwino komanso mokweza kuposa osakwera mtengo koma ndikuchita mopambanitsa.

Dzina la wopanga.

 

Pogula amplifier, ndikofunikira kwambiri kulabadira omwe adapanga. Ngati mumagula zinthu zopangidwa ndi manja, simungadalire kumveka bwino. Ndibwino kuti mutembenuzire kuzinthu zopenga zomwe zakhala pamsika kwa nthawi yaitali ndipo zakhala zikudziwika kale ndikuyamikira mbiri yawo. Mwachitsanzo, makampani monga Hertz, Alpine, DLS, Focal. Kuchokera pazachuma, mutha kutembenukira kuzinthu monga; Alphard, Blaupunkt, JBL, Ural, Swat, etc.

Kodi mwasankha kusankha amplifier? Nkhani yotsatira yomwe idzakhala yothandiza kwa inu ndi "momwe mungalumikizire amplifier yamagalimoto."

Momwe mungasankhire amplifier m'galimoto (kanema)

Amplifiers kwa SQ. Momwe mungasankhire amplifier mugalimoto

Inde, izi sizizindikiro zonse zomwe muyenera kuziganizira posankha amplifier, koma ndizo zikuluzikulu. Kutsatira malingaliro omwe afotokozedwa m'nkhaniyi, mutha kusankha chokulitsa choyenera pamakina anu omvera. Tikukhulupirira kuti tayankha funso lanu momwe mungasankhire amplifier kwa okamba kapena subwoofer, koma ngati mudakali ndi mfundo zosadziwika bwino kapena zokhumba, tidzakhala okondwa kuyankha mu ndemanga pansipa!
