Sungani Mtengo Weni Weni wa Mphamvu Yanu
Imodzi mwa nkhani zosokoneza kwambiri mu audio ndikulingalira kuti kukula kwake kukukulankhulani bwanji. Kawirikawiri, anthu amapanga chisankho chotero pogwiritsa ntchito wolankhula mophweka komanso nthawi zina opanda pake komanso zopereka zofunikira . Ambiri amakonda kutsata malingaliro okhudza momwe amps ndi okamba amagwirira ntchito. Takhala zaka zambiri kuyesa ndi kuyesa okamba - kuphatikizapo ife tapindula kumbuyo -kuwonetserako kuti tisalankhulane ndi akatswiri ambirimbiri a injini ndi maulendo amalonda mu bizinesi yamalonda - choncho apa pali zomwe muyenera kudziwa!
Zoona Zenizeni Zokhudza Woweruza Mphamvu Zogwira Zolemba
Choyamba, nkofunika kumvetsetsa kuti zomwe oyankhula pamagwiritsidwe ntchito kawirikawiri zimakhala zopanda pake. Kawirikawiri, mumangoona "mphamvu yapamwamba" kutanthauzira za momwe chidachokera. Kodi ndiyomweyi yopitirirabe? Average level? Msinkhu wa msinkhu? Ndipo zimakhala zotani kwa nthawi yayitali, ndipo ndizinthu ziti? Izi ndi mafunso ofunika kwambiri.
Mwamwayi, pakhala pali miyezo yambiri yotsutsana ndi kuyankhulana kwa magetsi, yofalitsidwa ndi Audio Engineering Society (AES), Electronic Industries Association (EIA) ndi International Electrotechnical Commission (IEC). Ndizodabwitsa kuti chifukwa chiyani munthu wamba angathe kusokonezeka pang'ono.
Pamwamba pa izo, ochuluka a opanga omwe tayankhula nawo samatsatira kwenikweni miyezo iyi; iwo amangopanga chidziwitso chophunzitsidwa. Kawirikawiri, chisankho ichi chimadalira mphamvu yogwiritsira ntchito subwoofer. (Kugwiritsira ntchito mphamvu zamagetsi pa madalaivala osakaniza, monga oofers ndi tweeters, ali ovomerezeka ndi ofunika kwambiri kuposa momwe angalankhulire okamba). Mwinanso mungaone wopanga amapereka wokamba mtengo kwambiri mphamvu yogwiritsira ntchito mphamvu poyankhula ndi wokamba mtengo wamtengo wapatali, ngakhale kuti onsewa amagwiritsa ntchito zovala zofanana.
Mipukutu ya Vesi vs. Mphamvu ya Amplifier
Ndikofunika kumvetsetsa kuti nthawi zambiri, 200 watt amp imatulutsa mphamvu yomweyo monga 10-watt amp. Izi ndi chifukwa chakuti omvera ambiri amapezeka pamagulu ochepa, kumene madzi osachepera 1 ali ndi mphamvu zokwanira okamba . Mulowezera wopatsidwa mwachindunji pamtundu wokhalapo woperekedwa, onse amphamvu amapereka mphamvu zofanana - malinga ngati atha kupereka mphamvu zambiri.
Kotero ndizoyimira voliyumu yomwe imakhudza, osati mphamvu ya amplifier. Ngati simukuphwanya dongosolo lanu kufika pamlingo umene voliyumu sizimveka bwino, mamembala anu sangatulutse zoposa 10 kapena 20 watts. Potero, mutha kulumikiza wotetezera 1,000-watt mwachinsinsi chaching'ono cha 2-inch. Musangotembenuzira voliyumu kuposa momwe wokambayo angayankhire.
Chimene simukuyenera kuchita ndi kutulutsa amphamvu amphamvu - nenani, chitsanzo cha 10 kapena 20-watt - kukhala wokamba nkhani ndikusintha voliyo mokweza. Mphamvu yotsika kwambiri imatha kusinthana (kusokoneza), ndi kudula kwa amplifier ndilo vuto lalikulu la oyankhula osalimba. Pamene amplifier yanu ikugwedeza, imatulutsa mpweya wamtundu wapamwamba wa DC molunjika poyankhula. Izi zikhoza kutentha mawu a madalaivala a wokamba nkhani akuwombera pafupifupi nthawi yomweyo!
Mmene Mungadziŵerengere Mtundu Womwe Amp Mukufunikira
Kusokoneza monga zonsezi zingawonekere, n'zosavuta kuwerengera kukula kwake kukula kwake. Ndipo gawo lopambana ndiloti mungathe kuchita izi pamutu mwanu. Sitidzakhala angwiro, chifukwa mudzadalira zomwe zimalankhula kuchokera kwa wokamba nkhani ndi amplifiers, zomwe nthawi zambiri zimakhala zosavuta komanso nthawi zina zimakopeka. Koma izo zikutseka iwe mokwanira. Nazi momwe mungachitire:
- Tengani mlingo wozindikiritsa wa wokamba nkhani , womwe ukufotokozedwa mu decibels (dB) pa 1 watt / mita imodzi. Ngati mndandanda uli mu chipinda kapena chipinda cha danga, gwiritsani ntchito nambala imeneyo. Ngati ndi anechoic spec (monga yomwe imapezeka muzolowera zowonongeka) yonjezerani +3 dB. Chiwerengero chimene muli nacho tsopano chidzakuwuzani mozama momwe wokamba nkhaniyo adzakulira mokweza mpando wanu womvetsera ndi chizindikiro cha 1-watt.
- Chimene tikufuna kufika ndi kuchuluka kwa mphamvu zomwe zimayenera kugunda pafupifupi 102 dB, zomwe zili pafupi kwambiri monga momwe anthu ambiri amafunira. Ndikumveka bwanji? Kodi munakhalapo mu kanema kofiira kwambiri? Malo owonetsedwa bwino omwe akuyendetsedwa pazomwe akufotokozera adzakupatsani pafupi 105 dB pa njira. Ndizofuula mokweza kwambiri kuposa momwe anthu ambiri akufuna kumvetsera - chifukwa chake masewera samakonda kusewera mafilimu pamtundu uliwonse. Kotero 102 dB amapanga cholinga chabwino.
- Pano pali mfundo yofunikira yomwe muyenera kudziwa; Kuti mutenge mauthenga owonjezerekawa +3 dB, muyenera kuwirikiza mphamvu ya amp amphamvu. Kotero ngati muli ndi wokamba nkhani omwe ali ndi chipinda chokhala ndi chipinda cha 88 dB pa 1 Watt, ndiye ma Watt 2 adzakupatsani 91 dB, 4 Watts adzakupatsani 94 dB, ndi zina zotero. Ingowerengera kuchokera apo: ma Watt 8 amakupatsani inu 97 dB, 16 Watts amakupatsani inu 100 dB, ndipo 32 Watts amakupatsani inu 103 dB.
Kotero chomwe inu muzisowa ndi amplifier zomwe zingathe kupereka ma Watts 32. Inde, palibe amene amapanga 32-watt amp, koma wolandira 40 kapena 50 watt kapena amplifier ayenera kuchita bwino. Ngati mukufuna amp amp ovomerezeka, nenani, Watts 100, musadandaule za izo. Kumbukirani, pafupipafupi kumvetsera ndi oyankhula okamba, amphamvu iliyonse imatulutsa pafupifupi 1 watt, komabe.
