Symmetrical uye unbalanced cables - kusiyana

Makombora ari pakati pezvinhu zvakakosha zvemidziyo ye studio imwe neimwe. Pasinei nekuti ichave yakakura nyanzvi studio kana diki, kazhinji yekumba studio, isu tinoshanda netambo mune imwe neimwe yadzo. Naizvozvo, kusarudza tambo yakakodzera yekubatanidza midziyo yedu yakakosha zvikuru uye inokanganisa kunaka kweruzha rwakawanikwa. Tisati taita sarudzo yekutenga, tinofanira kutanga tazivana nemhando dzavo, zvakanakira uye zvisingabatsiri, nokuti zvose symmetrical uye asymmetrical vanezvo.

Matambo asina kuenzana anosanganisira, pakati pevamwe vane maviri eRCA magumo, iyo inonzi cinches pamativi ese kana kwatine masendimita maviri kune rimwe divi uye jack kune rimwe, kana kwatine jack kumativi ese. Tambo idzi dzinosiyaniswa nenyaya yekuti dzine maconductor maviri mumutsara mumwe, imwe yacho ine basa reinzwi redhiyo uye imwe yepasi. Waya idzi dzinoita hurefu hwakazara hwetambo kubva pakupinza kuenda painobuda. Iyo yakaderera yemhinduro iyi ndeyokuti kana tambo inosangana nekumwe kukanganisa mumhando yemasaisai munzira yayo, izvi zvinokanganisa zvichabuda pamagumo uye zvichanzwika. Naizvozvo, idzi mhando dzetambo hadzifanirwe kushandiswa kwekubatanidza kwenguva refu sezvo dzichizounganidza ruzha rwakawanda munzira yavo zvekuti unogona kuinzwa kuburikidza nevatauri vako. Ehe, inokodzera kupfupika kwekubatanidza uye kune yakajairika kushandiswa kwemumba sekunge uchibatanidza shongwe, nekuti mumhando iyi yezvishandiso hapana zvinongedzo zviri nani pane zvisina kuenzana, saka iyo symmetrical tambo yaisazoshandiswa zvizere zvakadaro. Munzvimbo dzakachipa dzekuteerera kana masipika akachipa zvakare hapana symmetrical yekubatanidza, saka tambo isina kugadzikana yakadaro ichashandiswa ipapo. Iko kusakosha kukuru kwemhando iyi yetambo isina kuenzana ndeyekuti haishande zvakanaka kwekubatana kwenguva refu.

Nekudaro, nekurebesa kubatana hakuna dambudziko ne symmetrical tambo, iyo inonyanya kubatsira kune studio yekubatanidza. Uku kurwira kwemhando yepamusoro yehuzha ichokwadi chemazuva ese kune wese anonzwika director uye mugadziri. Nokudaro, rudzi urwu rwetambo runoshandiswa zvakanyanya kwete chete kwekubatana kwenguva refu, zvakadai semakonti akazaruka, asiwo kune mapfupi anoda kunyanya kujeka, kwepamusoro-soro. Mu studio, nerubatsiro rwavo, tinosanganisa, pakati pevamwe condenser maikorofoni ine odhiyo interface kana musanganiswa. Tambo idzi dzine dhizaini yakati siyanei uye dzinoshanda neimwe nzira yakati siyanei. Kune waya nhatu pano, kwete mbiri sezvaiitika kune dzisina kuenzana. Semuenzaniso, mune tambo yeXLR mune yakajairwa maikorofoni tambo, waya imwe ine mutoro wepasi, uye maviri ndiwo ane chekuita nechiratidzo chekuteerera. Sezvakaitika kune tambo isina kuenzana, waya idzi dzinobhururukawo kuburikidza nehurefu hwose hwetambo kusvika kune zvakabuda, nemusiyano wekuti masaini maviri ekuteerera akasiyana zvishoma. Aya ndiwo mamwe makopi echiratidzo, asi iyo yekupedzisira conductor ine 180 ° kuratidzwa kwechiratidzo, kureva kuti yakaitwa polarized, kureva mirror reflection. Iyi tambo, seyakaitika tambo isina kuenzana, inogonawo kusangana nekukanganisika kwakasiyana munzira, iyo ichaunganidzwawo nemusiyano chete wekuti pakupera kana chiratidzo chaburitswa, chiratidzo chakatanga kudzoserwa mune imwe ye tambo dzeaudio dzinodzoserwa zvakare uye dzakakwana netambo yechipiri yekuteerera. Izvi zvinoreva kuti ese aya masaini masaini ari muchikamu chinowirirana, polarized, ane yakafanana waveform, izvo zvinoita kuti kupindira kwakaunganidzwa munzira panguva yekuyerera kwechiratidzo kubviswe. Tine yakanyanya kuchena, chiratidzo chiri nani.

Symmetrical tambo dzinowanzo tambo dziri nani uye kunyangwe dzine mapfupi ekubatanidza zviri nani kuashandisa. Ehe, izvi zvine musoro chete kana midziyo yedu yatinoshandisa ichishandisa symmetrical yekubatanidza. Nekudaro, ivo vanofanirwa kushandiswa kune refu kubatana, nekuti ipapo isu tichanzwa zvakanyanya mumhando. Muchiitiko chekushandisa tambo isina kukwana yekubatanidza kwemamita mashoma, tinogona kutoona kuderera kwehutano hwechiratidzo, uye nekubatana kwemamita akawanda, zvinoonekwa. Kune symmetrical tambo, kunyangwe madaro e100 m haana kutyisa uye inobuda ruzha yakanaka kwazvo. Nekudaro, zvinofanirwa kugara zvichiyeukwa kuti iyo ipfupi nzira yeinzwi wave kufamba, zviri nani kunaka kweinobuda ruzha. Naizvozvo, ngatiedzei kusachengeta pane tambo uye, kana tapedza zvishandiso zvedu, edza kukwirisa saizi yayo kune icho chaidiwa.
