Mokhoa oa ho Tonesa Amplifier ea Koloi bakeng sa Mids le Highs (Tataiso e nang le linepe)
Tse ka hare
Sehloohong sena, ke tla u ruta mokhoa oa ho theha amplifier ea koloi bakeng sa maqhubu a bohareng le a phahameng ka metsotso e seng mekae.
Ho senyeha ha molumo ho etsahala haeba maqhubu a taolo ea phaello a behiloe holimo haholo. Joaloka motho ea chesehelang stereo e moholo ea neng a sebetsa lebenkeleng la li-stereo tsa likoloi, ke na le boiphihlelo ba ho etsa li-amplifiers ho ntlafatsa boleng ba molumo. O ka tlosa ho khopama ho stereo ea hau ka ho lokisa li-mids le trebles ka litlhophiso tsa treble le bass. Hape u tla qoba ho sotha molumo o senyang libui le likarolo tse ling tsa sistimi ea stereo, 'me u ke ke ua ba le tahlehelo kapa litšenyehelo tse ling ho lokisa sistimi ea hau ea molumo.
Kakaretso e Potlakileng: Mehato e latelang e tla lokisa amplifier ea koloi ea hau hantle bakeng sa bohareng le holimo:
- Ho bapala molumo kapa 'mino oo u o ratang haholo
- Fumana taolo ea phaello ka morao ho amplifier ebe u e lebisa bohareng.
- Fetola molumo hore e be karolo ea 75 lekholong
- Khutlisetsa taolo ea phaello 'me butle-butle u eketse khafetsa ho fihlela matšoao a pele a ho sotha a hlaha.
- U ka boela ua sebelisa multimeter ho fetola taolo ea phaello.
- Fetola switch ea HPF ho amplifier ebe u beha HPF ho 80Hz ho beha maqhubu a phahameng.
- Fetola maqhubu a mahareng lipakeng tsa 59 Hz le 60 Hz bakeng sa molumo o motle ka ho fetisisa.
- Tlosa litlhōrō tse matla le li-dips ka taolo ea EQ ea amp.
Ka tlase ke tla teba ho sena.
Ho lokisa maqhubu a mahareng le a holimo
Sebopeho sa amplifier se boetse se ipapisitse le mofuta oa amplifier ho stereo ea koloi ea hau. Ba qalang ba lokela ho etsa bonnete ba hore ha ho na maqhubu a tlase haufi le libui tsa bona.
Hape, o hloka sebaka se nepahetseng sa Gain ho fumana ipf le hpf e nepahetseng bakeng sa li-mods le maxes. Qoba ho khopama, le hoja ho ka fokotsoa kapa ho felisoa habonolo. Ho khopama ho ka baka tšenyo e ke keng ea boleloa ho libui le litsebe tsa hau. Ho khopama ho etsahala ha o beha taolo ea phaello e phahameng haholo ebe amplifier e romella libui tse khutsufalitsoeng ho libui. Mmino o lerata o mpefatsa dintho le ho feta hobane dibui di se di tletse.
Mokhoa oa ho beha taolo ea phaello
Ho etsa sena:
hata 1. Bapala pina eo u e tsebang hobane u tseba hore na e utloahala joang.
Ho amp, fumana konopo ea Gain 'me u e fetole hoo e batlang e le halofo ea tsela - u se ke ua e beha matla a feletseng.
hata 2. Fetolela molumo ho fihlela ho liperesente tse 75 - ho khopama ho qala ka melumo e phahameng haholo, kahoo u se ke ua beha molumo ho fihla holimo.
hata 3. Mamela 'mino o bapalang 'me u bone hore na o monate.
hata 4. Khutlela taolong ea phaello ka morao ho amplifier 'me u e lokise (ka thata) ho fihlela ho khopama ho qala. Khaotsa ho phahamisa molumo hang ha u bona mesaletsa ea ho sotha.
Ntle le moo, o ka sebelisa multimeter ho fetola taolo ea phaello.
Ho beha boholo
Haeba u batla feela maqhubu a phahameng ho libui tsa hau, joale HPF high pass filter ke seo u se hlokang. HPF e thibela matšoao a fokolang a fokolang a sa hlahisoang hantle ke libui le li-tweeters. Matšoao a tlase a ka chesa libui tsa hau, kahoo HPF e thusa ho thibela sena.
Mehato e latelang e tla u thusa ho lokisa treble:
Mohato oa 1: Flip switch ea Hpf ho amplifier, kapa sebelisa screwdriver ho e lokisa haeba ho se na switch ho eona.
Ho kenya li-setting, tobetsa konopo ea "high pass filter" ho amplifier ea hau. Li-amps tse ngata li na le switch, empa ho latela OEM.
Mohato oa 2: Beha Sefe ea High Pass ho 80Hz
Li-HPF li hlokomela ts'ebetso ea tsona e ntle ka ho fetisisa ho tloha ho 80Hz ho isa ho 200Hz, empa ea pele ke eona e ntle ka ho fetisisa.
Maqhubu afe kapa afe a ka tlase ho 80Hz a lokela ho isoa ho subwoofer le libui tsa bass. Kamora ho beha HPF ho 80Hz, lokisa LPF ho hapa maqhubu a ka tlase ho 80Hz. Kahoo, o felisa likheo tsa tlhahiso ea molumo - ha ho na maqhubu a setseng ntle le tlhokomelo.
Ho beha maqhubu a mahareng
Batho ba bangata ba mpotsa hore na ke tlhophiso efe ea frequency e molemo bakeng sa maqhubu a mahareng. Ke tsena!
Mohato oa 1: Fetola mahareng pakeng tsa 50Hz le 60Hz.
Ho bohlokoa haholo ho hopola hore karolelano ea maqhubu a sebui se seholo sa koloi e pakeng tsa 50 Hz le 60 Hz. Leha ho le joalo, li-audiophiles tse ling li sebelisa li-equalizer bakeng sa tatso e poteletseng haholoanyane. Kahoo, fumana kotola ea midrange ho amp mme u e behe ho 50Hz kapa 60Hz.
Mohato oa 2: Tlosa litlhōrō tse bohale le li-dips
Ho etsa sena, sebelisa modulation kapa li-setting tsa equalizer. Litlhōrō tse bohale le li-dips li etsa melumo e bohale, kahoo etsa bonnete ba hore u li felisa ka litlhophiso tsa EQ tsa amp ea hau. (1)
Litlhophiso tsa Equalizer li boetse li arola molumo ka maqhubu a tlase, a mahareng le a phahameng. Sena se o nolofalletsa ho li etsa ka mokhoa oo u ratang ka teng; Leha ho le joalo, ba bang ba khetha ho sebelisa app ho tune amplifier. Empa ka kakaretso o hloka ho beha maemo a holimo hanyane ho feta li-mids bakeng sa molumo o motle ka ho fetisisa.
Qetellong, ha u theha litlhophiso tsa amplifier, etsa bonnete ba hore li lumellana le litlhoko tsa hau. Batho ba na le tatso e fapaneng ea molumo, 'me se utloang se le monate ho uena se ka 'na sa e-ba lerata ho motho e mong. Ha ho na molumo o mobe kapa o motle kapa litlhophiso tsa amplifier; Taba ke ho felisa ho sotha.
Mantsoe a mantlha le litlhophiso tsa amplifier
Hoa hlokahala ho utloisisa mantsoe a motheo le mokhoa oa ho theha amplifier ea koloi pele u fetola li-mids le tse phahameng. Liphetoho tse kang 'mino o letsoang, sebui, kapa tsamaiso eohle li ama molumo oa bohareng le o phahameng.
Ho phaella moo, ho na le likonopo tse 'maloa kapa litlhophiso tse ka morao ho amplifier tse hlokang tsebo e ntle ea amplifier. Ho seng joalo, u ka ferekana kapa ua khopamisa maemo. Ka tlase ke tla tšohla lintlha tsa sehlooho ka botlalo.
khafetsa
Khafetsa ke palo ea oscillation ka motsotsoana, e lekantsoeng ho Hertz, Hz. [1 Hertz == 1 potoloho ka motsotsoana]
Ka maqhubu a phahameng, mats'oao a molumo a hlahisa melumo e phahameng. Ka hona, maqhubu ke karolo ea bohlokoa ea maqhubu a mahareng le a phahameng a molumo kapa 'mino.
Bass e amahanngoa le bass, 'me u tlameha ho ba le libui tsa bass hore u utloe maqhubu a tlaase. Ho seng joalo, maqhubu a seea-le-moea a tlaase a ka senya libui tse ling.
Ka lehlakoreng le leng, maqhubu a phahameng a hlahisoa ke lisebelisoa tse kang licymbala le lisebelisoa tse ling tse phahameng. Leha ho le joalo, ha re khone ho utloa maqhubu ohle - lebelo la tsebe ke 20 Hz ho isa ho 20 kHz.
Li-frequency tse ling ho li-amplifiers tsa koloi
Baetsi ba bang ba thathamisa khafetsa ho li-decibel (dB) tsa LPF, HPF, super bass, joalo-joalo.
Fumana (boikutlo ba ho kenya letsoho)
Gain e hlalosa maikutlo a amplifier. U ka sireletsa sistimi ea hau ea stereo ho sotha molumo ka ho fetola phaello ka nepo. Kahoo, ka ho fetola phaello, o fumana molumo o eketsehileng kapa o fokolang ha o kenya amplifier. Ka lehlakoreng le leng, molumo o ama feela tlhahiso ea sebui.
Litlhophiso tsa phaello e phahameng li tlisa molumo haufi le ho sotha. Tabeng ena, o tlameha ho lokisa li-setting tsa phaello ho felisa ho khopama ho tsoa ho sebui. U tla etsa bonnete ba hore sebui se fana ka matla a lekaneng feela ho felisa ho sotha molumo.
Lifapano
Li-Crossover li netefatsa hore lets'oao le nepahetseng le fihla mokhanni oa lona ea nepahetseng. Sena ke sesebelisoa sa elektroniki se hahelletsoeng ka har'a potoloho ea molumo ea koloi ho arola maqhubu a molumo ka mekhahlelo e fapaneng. Mofuta o mong le o mong oa maqhubu o fetisetsoa ho sebui se loketseng - tweeters, subwoofers le woofers. Li-tweeters li fumana maqhubu a phahameng, athe li-subwoofers le li-woofers li fumana maqhubu a tlase haholo.
Li-Filters tsa High Pass
Ba fokotsa maqhubu a kenang libui ho ea ho maqhubu a phahameng feela - ho fihlela moeli o itseng. Ka hona, maqhubu a tlase a thibetsoe. Ka hona, li-filters tse phahameng li ke ke tsa sebetsa le li-tweeters kapa libui tse nyenyane tse ka senyehang ha matšoao a tlaase a feta ka har'a sefe.
Lisefe tsa Low Pass
Li-filters tse tlase li fapane le li-filters tse phahameng. Li u lumella ho fetisetsa maqhubu a tlase (ho fihlela moeling o itseng) ho li-subwoofers le li-woofers - libui tsa bass. Ntle le moo, li sefa lerata ho tsoa mats'oao a molumo, li siea matšoao a boreleli ka morao.
Ho akaretsa
Ho theha amplifier ea koloi bakeng sa maqhubu a mahareng le a phahameng ha ho thata. Leha ho le joalo, o tlameha ho utloisisa likarolo tsa mantlha kapa likarolo tsa tokiso ea molumo - khafetsa, li-crossovers, fumana taolo, 'me li-filters li fete. Ka 'mino oo u o ratang haholo le tsebo e nepahetseng, u ka khona ho fumana melumo e makatsang tsamaisong ea hau ea stereo. (2)
