ISIQINISEKISO SOKUPHAZAMISEKA

Lo msebenzi usinceda ngokukhawuleza nangokuchanekileyo ukuseta inzuzo ye ampi-lifier ukuqinisekisa ukuba nokuba uphezulu kangakanani na umthamo wenginginya uhlengahlengiswe, awuzukukhupha amandla agqithisileyo anokonakalisa ampi-lifier okanye izithethi. Ukwenza uvavanyo, kuya kufuneka usebenzise i-audio yovavanyo files igcinwe kwi-USB flash drive ehamba nayo (Ingoma 1: 40Hz -0dB kunye neTrack 2: 1kHz -0dB).

Ukuvavanya ubuninzi bevolumu engagqwethwanga yomamkeli:

• Ngaphambi kokuvavanya, cima i-EQ yomninimzi, izicwangciso ze-crossover, kwaye usethe i-bass kunye ne-treble adjustments ukuya kwi-0. Emva kokuba uvavanyo lugqityiwe, ezi zicwangciso zingabuyiselwa ngokwezinto ozikhethayo.
• Khetha "I-Distortion Detector" kwimenyu ephambili kwaye ucinezele u-"Enter" ukufaka olu jongano lomsebenzi. Landela imiyalelo ekwisikrini ukudibanisa igalelo/imveliso yesixhobo esisebenza ngeendlela ezininzi kwenye yeetheminali zemveliso yesandi yenginginya (nokuba ngqo kwizibuko lokufaka iRCA okanye usebenzisa intambo yoncedo).
• Dlala uvavanyo lwe-audio Track 1: 40Hz -0dB ngenginginya. Yandisa kancinane ivolyum yenginginya. Isikrini siya kubonisa "40Hz DETECT" ekhanyisiweyo kwaye isalathisi sokuphazamiseka siya kuba luhlaza, ngelixa sibonisa ivolumu yomsindo efunyenweyo.tage.
• Qhubeka ngokucotha ukunyusa umthamo wenginginya de kube "DISTORTION" ilayita kwaye isalathisi sokuphazamiseka sijika sibe bomvu. Emva koko wehlise ivolumu ngokucothayo de “DISTORTION” ijike ibe ngwevu kwaye isalathisi sokugqwetha sijike sibe luhlaza kwakhona. Rekhoda useto lwevolyum ngeli xesha.
• Tshintshela ukuvavanya i-audio Track 2: 1kHz -0dB. Phinda amanyathelo cd.
• Thatha umndilili wesethingi yevolyum erekhodiweyo njengowona mthamo uphezulu ungagqwethwanga.

  Ukuseta i ampubuninzi bevolumu engagqwethwanga ye-lifier:
• Ngaphambi kokuvavanya, cima i-EQ yomninimzi, izicwangciso ze-crossover, kwaye usethe i-bass kunye ne-treble adjustments ukuya kwi-0. Emva kokuba uvavanyo lugqityiwe, ezi zicwangciso zingabuyiselwa ngokwezinto ozikhethayo. Seta ivolyum yenginginya iye kubuninzi bevolumu engagqwethwanga egqitywe kwinyathelo langaphambili.
• Lungisa i ampumthamo we-lifier ukuya kwindawo encinci; khubaza i ampI-lifier's crossover kunye nezicwangciso zokucoca. Nqamula zonke izithethi eziqhagamshelwe kwi ampiitheminali zemveliso ye-lifier. Ukuba yi-subwoofer ampi-lifier, seta i-low-pass frequency kwisikhundla esiphezulu. Ukuba kukho i-bass boost knob, yibeke kwindawo eqhele ukusetyenziswa ngexesha lomsebenzi wesiqhelo.
• Khetha "I-Distortion Detector" kwimenyu ephambili kwaye ucinezele u-"Enter" ukufaka olu jongano lomsebenzi. Landela imiyalelo ekwisikrini ukudibanisa igalelo/imveliso yesixhobo esinemisebenzi emininzi yesixhobo kwenye yezi ampiitheminali eziphumayo ze-lifier (sebenzisa intambo yoncedo, ngocingo olubomvu oluqhagamshelwe kwitheminali evumayo kunye nocingo olumnyama oluqhagamshelwe kwi-terminal ethabathayo).
• Dlala uvavanyo lwe-audio Track 2: 1kHz -0dB ngenginginya (ukuba yi-subwoofer ampi-lifier, dlala i-audio Track 1: 40Hz -0dB).
• Yandisa kancinci i ampivolumu ye-lifier de kube "DISTORTION" ilayita kwaye isalathisi sokugqwetha sijike sibebomvu. Emva koko wehlise ivolumu ngokucothayo de “DISTORTION” ijike ibe ngwevu kwaye isalathisi sokugqwetha sijike sibe luhlaza kwakhona.
• Le ndawo imele ubuninzi obungagqwethwanga umthamo we ampi-lifier kumamkeli wangoku-ampinkqubo ye-lifier.

UMvavanyi wesiGaba
Inqanaba elingangqinelaniyo phakathi kwezithethi kwisixokelelwano somsindo kunokukhokelela ekubeni amaza omsindo arhoxise omnye ngaphandle, okukhokelela kwizandi ezingaqondakaliyo.tage kunye nokungabikho kwemvakalelo yestereo. Lo msebenzi uchonga isigaba sesithethi ngasinye kwisixokelelwano somsindo kwaye unokujonga kwakhona i-polarity yeetheminali zocingo zesithethi ngasinye. Ubhaqo kufuneka lwenziwe kwindawo ezolileyo ngokwentelekiso, njengokuvula iingcango zemoto kunye ne-air conditioning yemoto kunye nezinye izixhobo ezibangela ingxolo. Uvavanyo lufuna ukusetyenziswa komsindo wovavanyo file igcinwe kwi-USB flash drive ekhaphayo (Umkhondo 3: Isiginali yovavanyo lweSigaba).
Inkqubo yoMvavanyi weSigaba:

• Emva kokufaka inkqubo ye-audio, dlala i-audio Ingoma yesi-3: Isibonakaliso sovavanyo lweSigaba ngomsingathi kwaye ulungelelanise ivolumu kwizinga elifanelekileyo.
• Khetha "Umvavanyi weSigaba" kwimenyu ephambili kwaye ucinezele u-"Enter" ukuze ufake i-"Phase Tester in the System" interface. Landela imiyalelo ekwisikrini ukuze ubeke isamkeli semayikrofoni yangaphambili yesixhobo kufutshane kwaye sijonge phambili kwisithethi esivavanywayo.
• Isixhobo siya kubonisa i-polarity yesiginali nganye efunyenweyo ngexesha langempela, ebonisa isigaba esihle,okanye isigaba esingalunganga). Emva kokufumanisa imiqondiso emi-4 esebenzayo, isigaba sesithethi sinokumiselwa. Isikrini siza kubonisa ngokuqhubekayo ulwazi lwesigaba esisebenzayo esifunyenwe kwizinto ezimbini zokuqala ezilandelelanayo.
•  Ukuba kufunyenwe izigaba zesithethi ezingangqinelaniyo, tshintsha zonke izithethi zibe kwisigaba esivumayo okanye esibi (tshintsha isithethi esivumayo okanye esinegetive iingcingo zoqhagamshelo lwepolarity okanye utshintshe useto lwesigaba kwinkqubo yeDSP).

Umvavanyi weSigaba seSithethi EsiSinye:

• Kwi-interface ye-"Phase Tester in the System", cofa ukutshintshela kwi-interface ye-"Single Speaker Polarity Detection".
• Landela imiyalelo ekwisikrini ukudibanisa zombini iitheminali zesithethi kusetyenziso lwesixhobo esinemisebenzi emininzi yegalelo/izibuko lemveliso usebenzisa intambo yoncedo. Misa isamkeli semayikrofoni yangaphambili yesixhobo kufutshane kwaye ujonge ngaphambili kwisithethi.
• Isixhobo siya kubonisa i-polarity yesiginali echongiweyo nganye ngexesha langempela , ebonisa isigaba esihle, ibonisa isigaba esingalunganga). Ukuba kufunyenwe isigaba esilungileyo, i-terminal eqhagamshelwe kucingo olubomvu lwentambo yoncediso yitheminali evumayo yesithethi. Ukuba kufunyaniswe inqanaba elilandulayo, i-terminal eqhagamshelwe kucingo olumnyama lwentambo yoncediso yitheminali ephozithivu yesithethi.
