Zomwe Anthu Ambiri Amakhulupirira Zokhudzana ndi Kutaya ndi Vuto
Mphamvu ya amplifier , yoyezedwa mu watts, ikhoza kusokoneza nkhani ndipo nthawi zambiri imamvetsetsedwa bwino. Zomwe anthu ambiri amaganiza ndizokuti kutulutsa madzi kumagwirizanitsa molunjika kapena mokweza. Ena amakhulupirira kuti kukayikira mphamvu zomwe zimatuluka zidzatulutsa voliyumu mokweza mobwerezabwereza. Ndipotu, mphamvu sichinthu chokwanira. Mphamvu zotulutsa mphamvu zimakhudza zokhudzana ndi mfundo zazikulu ziwiri:
- Kulankhula bwino
- Mphamvu yamagetsi amatha kuyimba nyimbo
Kulumikiza Kwachinsinsi
Mphamvu ya kulankhula, yomwe imadziwikanso kuti ndi yotulutsa mawu, ndiyeso ya wokamba nkhaniyo, yomwe imayesedwa pamagetsi, ndi mphamvu yowonjezera. Mwachitsanzo, kukambitsirana kwa oyankhula nthawi zambiri kumayesedwa ndi maikolofoni (yogwirizana ndi mita ya mlingo) imayikidwa mita imodzi kuchokera kwa wokamba nkhani. Mphamvu imodzi yamagetsi imaperekedwa kwa wokamba nkhani ndipo mamita a msinkhu amatsitsa voliyumu m'magetsi. Chiwerengero cha zotsatira chimasintha muyeso.
Oyankhula amayenda bwino kapena mphamvu kuchokera ku 85dB (osadziwika bwino) kufika 105dB (zothandiza kwambiri). Poyerekezera, wokamba nkhani ali ndi 85 dB yowonjezereka bwino amatenga kawiri mphamvu ya amplifier kuti afike pamutu womwewo ngati wokamba nkhani ali ndi mphamvu 88 dB. Mofananamo, wokamba ndi chiwerengero cha 88 dB chodziwika bwino amafunika mphamvu khumi kuposa momwe wokamba nkhani aliri ndi 98 dB momwe angagwiritsire ntchito pa msinkhu umodzimodzi. Ngati mukuyamba ndi wolandila 100 watt / njira, mungafunike ma Watts 1000!
Mphamvu Yamphamvu
Nyimbo ndizochilengedwe. Nthawi zonse zimasintha mlingo wake komanso nthawi zambiri. Njira yabwino yodziwira nyimbo ndizovuta kumvetsera nyimbo zokondweretsa (un-amplified). Mwachitsanzo, gulu la oimba limakhala ndi mavoliyumu osiyanasiyana, kuchokera ku ndime zakuya kwambiri, kupita ku crescendos mokweza ndi zina pakati pa bata ndi phokoso. Mndandanda wa voliyumu umadziwika ngati kukula kwakukulu, kusiyana pakati pa ndime zofewa kwambiri komanso zazikulu kwambiri.
Pamene nyimbo zomwezo zimatulutsidwa kupyolera mu mauthenga a audio, dongosololi liyenera kubzala mofanana mofuula. Mukamaliza kusewera pamtundu wa voliyumu, ndime zosavuta ndi zazing'ono zomwe zili mu nyimbo zikufuna mphamvu zochepa. Ngati wolandirayo ali ndi mphamvu 100 zamtundu uliwonse pagulu, ndime zofewa ndi zapakati zingafune pafupifupi 10-15 watts amphamvu. Komabe, ma crescendos mu nyimbo angafunike mphamvu yochulukirapo kwa nthawi yochepa, mwina ma Watt 80. Chinthu china chabwino. Ngakhale kuti ndizochitika kanthawi kochepa, kuwonongeka kwa chimbalangondo kumafuna mphamvu zambiri kwa kanthaŵi kochepa. Kukhoza kwa wolandila kupereka mphamvu zopitilira kwa kanthaŵi kochepa ndikofunikira kuti abereke molondola. Ngakhale wolandirayo angagwiritse ntchito kagawo kakang'ono kowonjezera nthawi zambiri, ayenera kukhala ndi 'mutu' kuti apereke mphamvu zochuluka kwa nthawi yochepa.
