Isithasiselo A: Izincomo zezintambo
Njengamanje, cishe usuxhume iziqaphi ze-LSR futhi wenza umculo omnandi. Nokho, ukuze usebenze ngokugcwele, ukunaka okuthile emininingwaneni yezintambo manje kunganciphisa ukuwohloka kwesistimu kamuva. Lezi zincomo zekhebula zilandela umkhuba wezintambo ojwayelekile wokufaka okuhlukile.

Imithombo Elinganiselayo
Indlela engcono kakhulu yokusebenzisa isistimu yakho ibhalansile, lapho kokubili amasiginali "HOT" (+) kanye "COLD" (-) anikezwa kusukela kumthombo kanye ne-GROUND/SHIELD. Lokhu kuvame ukuthwalwa ngamakhebuli avikelwe angu-2 anezixhumi ze-XLR kuzo zombili iziphetho. Kungenjalo, izixhumi ezinojeke Ithiphu, Iringi, neSleeve (T/R/S) zingasetshenziswa. Noma nini lapho kunokwenzeka, isivikelo sekhebula akufanele sixhunywe kunoma iyiphi iphinikhodi, kodwa siyekwe ukuze senze umsebenzi wokuvikela ikhebula kuphela.

Qaphela: Ngaphansi kwezimo akufanele kukhishwe intambo yaphansi yokuphepha kusixhumi samandla e-AC. Uma usebenzisa imithombo elinganisiwe nge-LSR28P, kungaba okokufaka kwe-XLR noma i-T/R/S yesixhumi se-Neutrik “Combi” singasetshenziswa. Umehluko phakathi kwakho kokubili ukuthi i-T/R/S isethelwe okokufaka kwegama -10 dBv, futhi i-XLR isethelwe +4 dBu.

Ukuze uthole amasignali abhalansile, isignali ye-HOT (+) evela kumthombo wakho kufanele ixhunywe ekugcineni kwesixhumi se-T/R/S noma i-Pin 2 yokokufaka kwe-XLR njengoba kuboniswe kuMfanekiso A. Isignali “COLD” (-) kufanele ixhunywe ku-Pin 3 ye-XLR noma “Ring” yesixhumi se-T/R/S. Ukuze ugweme amaluphu aphansi, xhuma i-SHIELD ekugcineni komthombo kodwa hhayi kokokufaka kwe-LSR.
Qaphela: I-LSR12P isebenzisa okokufaka nokuphumayo kwe-XLR kuphela.

Imithombo Engalingani
Uma usebenzisa imithombo engalinganiseli, maningi amathuba okwethula amaluphu aphansi ohlelweni.
I-LSR28P ne-12P zinikeza izindlela ezimbalwa zokusiza ekudambiseni izinkinga ezingaba khona ngemishini engalingani.

Yize kukhona ukuxhumana OKUSHISAYO neGROUND/SHIELD kuphela okuvela emithonjeni engalinganiseli, kuyanconywa ukuthi kusetshenziswe ikhebula ebhangqiwe ephothiwe yekhwalithi ephezulu. Umfanekiso B ubonisa umthombo ongalinganiseli oxhunywe kokokufaka kwe-XLR okunokulinganisela kwemonitha ye-LSR kusetshenziswa ikhebula elisontekile. Qaphela ukuthi isihlangu sixhunywe kusixhumi se-GROUND/SHIELD kokokufaka kwe-LSR, kodwa hhayi emthonjeni. Lokhu kunciphisa amathuba okuthi kwethulwe iluphu yaphansi ohlelweni.

Uma usebenzisa amasiginali angalinganiseli nge-LSR28P, kunconywa ukuthi usebenzise isixhumi esingu-1/4” Ithiphu/Indandatho/Isikhono Lokhu okokufaka kwakhelwe ngokukhethekile ukuthwala ukuhlanganisa okubanzi okunokulinganisela nokungalinganisi kwe-C imibukiso lapho kusetshenziswa i-1/4” Ithiphu/Indandatho/umkhono wokufakwayo kufanele kube i-GROUND yomthombo wokuxhumana ophelele ukusebenza.

Umfanekiso D unikeza imininingwane ngoxhumo kusetshenziswa ikhebuli ene-conductorelded single ngepulaki ethi Ithiphu/Indandatho/Isikhwama okokufaka kwe-LSR28P. Ikhebula eline-conductor eyodwa kufanele lisetshenziswe njengendlela yokugcina, njengoba linikeza amathuba amaningi okuba nezinkinga. Isignali ethi “HOT” (+) kufanele ixhunywe ekugcineni kwepulaki ethi Ithiphu/Indandatho/Isikhwama. I-GROUND kufanele inamathiselwe Kwindandatho yepulaki Yethiphu/Indandatho/Isikhwama kokokufaka kwe-LSR28P.

Umfanekiso E unikeza imininingwane ngoxhumo kusetshenziswa ikhebula elingalingani kanye noxhumo Lwethiphu/Imkhono kokokufaka okungu-1/4”. Kule modi, Ukukhala kanye Nesikhwama sokokufaka kwe-LSR kufinyezwa ipulaki ngokuzenzakalelayo.
