Iingcamango eziqhelekileyo malunga nokutya kunye nomqulu
Amplifier amandla , kulinganiswe kwi-Watts, ingaba yinto yokudideka kwaye ayiqhelekanga kakuhle. Ukungaqondi kakuhle oku kukuthi ukuthambisa kunokubambisana ngokuthe ngqo kumsindo okanye ngevolumu. Abanye bakholelwa ukuba okuphindwe kabini ukuveliswa kwamandla kuya kubangela umthamo ophezulu ophindwe kabini ngelizwi. Enyanisweni, amandla akananto yokwenza ngokukhawuleza. Ukuveliswa kwamandla kuhambelana nemibandela emibini ephambili:
- Ukusebenza kakuhle kweSomlomo
- Ikhono le-amplifier yokusingatha iziqongo zomculo
Somlomo Usebenze
Ukusebenza kweSomlomo, kwaziwa nangokuthi isistim sokubamba isistim , isilinganiselo sesiphumo sesithethi, esilinganiswe kwi-decibels, kunye nenani elichaziweyo lamandla okukhulisa. Ngokomzekelo, ukusetyenziswa kwesithethi kudlalwa kulinganiswa kunye nemakrofoni (exhunywe kumitha wemitha yesandi) ibeke enye imitha kwisithethi. Elinye ilitha lamandla linikezelwa kwisithethi kwaye imitha yemilinganiselo yenza amanani kwi-decibels. Isiphumo siphumo siphumela kwimilinganiselo yokusebenza kakuhle.
Abathengisi beentlobo ekusebenzeni kakuhle okanye uvakalelo ukusuka kuma-85dB (amaninzi angasebenzi) ukuya kwi-105dB (efanelekileyo). Njengokuthelekisa, isithethi nge-85 dB yokulinganisa ukusebenza kuya kuthatha kabini amandla okukhulisa amandla ukuba afinyelele umqulu ofanayo kunye nesithethi nge-88 dB. Ngokufanayo, isithethi esinomlinganiselo we-88 dB osebenza kakuhle siya kufuna amandla angaphezu kweshumi ngaphezu kwesithethi nge-98 dB yokulinganisa ukuphumelela ukudlala kwinqanaba elifanayo. Ukuba uqala nge-receiver ye-watt / 100, uzakufuna ama-watts angu-1000 (!) Okuphuma kumbane ukuphindwe kabini kwinqanaba levolumu.
Rynamic Range
Umculo uphezulu kwendalo. Ihlala ishintsha kwinqanaba levolumu kunye nexesha. Indlela eyona ndlela yokuqonda umculo oguquguqukileyo womculo kukuphulaphula ukuhlala kumculo womculo ongabonakaliyo (un-amplified). I-orchestra, umzekelo, inamanani amaninzi aphezulu, ukusuka kwiindinyana ezithulekileyo, ukuya kwii-crescendos ezivakalayo kunye nokunye phakathi phakathi kokuthula nokuvakalayo. Uluhlu kumgangatho wevolumu luyaziwa njengoluhlu olushukumisayo, umahluko phakathi kweendinyana ezilula kwaye zikhulu kakhulu.
Xa umculo ofanayo uphinde uphinde uvelise nge-audio system, inkqubo kufuneka ivelise ibanga elifanayo ngokuphakamisa. Xa udlalwa ngasemva kwinqanaba levolumu, amavesi athambileyo kunye namanqanaba omculo ayakufuna amandla amancinci. Ukuba umntu owamkeleyo wayenama-watts angama-100 ngamashishini ngamnye, iifayile ezithambileyo neziphakathi zifuna i-10-15 watts zamandla. Nangona kunjalo, ii-crescendos zomculo ziza kufuna amandla amaninzi angamaxesha ambalwa, mhlawumbi ama-watts angama-80. Omnye umzekelo omhle. Nangona sisiganeko esifutshane, umonakalo wecimbil ufuna amandla amaninzi ngexesha elifutshane. Ubungakanani bomntu owamkelayo ukunikezela kwamandla emfutshane ngexesha elifutshane kubalulekile ukuveliswa ngokuchanekileyo kwezandi. Nangona i-receiver isebenzise kuphela inxalenye encinci yesiphumo sayo esona sikhulu ixesha, kufuneka ukuba 'igumbi eliphezulu' likhulule inani elikhulu lamandla kwixesha elifutshane.
