Sisoloko sidibana neengxaki ezininzi zesandi kwinqanaba. Umzekelo, ngenye imini izithethi ngequbuliso azivuli kwaye akukho sandi kwaphela. Umzekelo, isandi sesandi senqanaba siba nodaka okanye iqhina alinakuphuma. Kutheni kukho imeko enjalo? Ukongeza kubomi benkonzo, indlela onokuyisebenzisa ngayo imihla ngemihla kukukwazisa ngesayensi.

1.Cakela kwingxaki ye-wiring yamanqanaba. Ngaphambi kokumamela, jonga ukuba i-wiring ichanekile kwaye nokuba imeko ye-potentiometer inkulu kakhulu. Uninzi lwezi zithethi zangoku zenziwe ngoncedo lwamandla angama-220v, kodwa azange zigwetywe ukuba ezinye iimveliso ezingeniswayo zisetyenziswa. Uninzi lwezi zibhalo zisebenzisa ubonelelo lwe-110V yamandla. Ngenxa yokungafikeleli kwi-voltage ukungangqinelani, isithethi sinokutsalwa.

IZIXHOBO ZOKUGQIBELA. Uninzi lwabantu lubeka izithethi, imingxunya, abaguquli be-digital-to-counts-toward kunye nabanye oomatshini abaphezulu, obuya kwenza ukuba isandi sokuphazamiseka, esiya kwenza ukuba isandi sibe nzima kwaye sivelise imvakalelo yoxinzelelo. Indlela echanekileyo kukubeka izixhobo kwi -udio rack ezenziwe ngumzi-mveliso.

3.Ingxaki yokucoca yamasinga. Xa ucoca izithethi, kuya kufuneka unikele ingqalelo ekucoceni i-SEPINALS, kuba iintambo ze-SESTB ziya kuba ngaphezulu okanye zingaphantsi kwe-oxidod emva kokuba izithethi zisetyenziswa kangangexesha elithile. Le filli ifilimu yesidida iya kuchaphazela kakhulu imeko yoqhakamshelwano, ngaloo ndlela ihlukumeza umgangatho wesandi. , Umsebenzisi kufuneka acoce amanqaku onxibelelwano ngearhente yokucoca ukuze agcine olona nxibelelwano lubalaseleyo.

Ukuphathwa kwe-wiring. Sukuyibopha intambo yamandla kunye nomgca womqondiso kunye xa uphatha i-wiring, kuba ukutshintsha kwangoku kuya kuchaphazela umqondiso; Akukho mgca womqondiso okanye umgca wesithethi unokuthintelwa, kungenjalo kuya kuchaphazela isandi.

5. Sukukhetha imakrofoni kwizithethi zenqanaba. Isandi sesithethi singena kumbhobho, iya kuba yimpendulo ye-acoustic, ivelise ukuba iphile, kwaye iqhube inxenye ephezulu kunye neziphumo eziphezulu. Okwesibini, izithethi kufuneka zibe kude namabala e-magnetic eqinileyo, kwaye zingakufuphi nezinto zenziwe ngendlela ebonakalayo, njengabangayikhiyo kunye neefowuni eziphathwayo, njl njl.
