ISihlomelo A: Iingcebiso ngeeNcingo
Ukuza kuthi ga ngoku, uqhagamshelwe iimonitha ze-LSR kwaye wenza umculo omnandi. Nangona kunjalo, ukusebenza ngokugqibeleleyo, ukuqwalaselwa okuthile kwiinkcukacha zocingo ngoku kunokunciphisa ukuthotywa kwenkqubo kamva. Ezi zindululo zeekheyibhuli zilandela inkqubo yokufaka iintambo ezisemgangathweni kumagalelo ahlukeneyo.

Imithombo elungeleleneyo
Eyona ndlela ingcono yokuqhuba inkqubo yakho ilungelelene, apho zombini imiqondiso ethi "HOT" (+) kunye ne "COLD" (-) inikezelwa ukusuka kumthombo kunye ne-GROUND/SHIELD. Ezi ziqhele ukuthwalwa kwiintambo ezi-2-conductor ezikhuselweyo ezineziqhagamshelo ze-XLR kuzo zombini iziphelo. Kungenjalo, izihlanganisi ezineTip, iRingi, kunye neSleeve (T/R/S) iijacks zingasetyenziswa. Nanini na xa kunokwenzeka, isikhuselo sekhebula akufanele sidityaniswe nakweyiphi na iphini yomqondiso, kodwa ishiywe ukwenza umsebenzi wokukhusela intambo kuphela.

Phawula: Naphantsi kwazo naziphi na iimeko kufuneka ucingo olusezantsi lokhuseleko lususwe kwisidibaniso samandla se-AC. Xa usebenzisa imithombo elinganayo kunye ne-LSR28P, mhlawumbi i-XLR okanye i-T / R / S igalelo le-Neutrik "Combi" ikhonkco ingasetyenziswa. Umahluko phakathi kwezi zibini kukuba i-T/R/S imiselwe i-nominal -10 dBv input, kwaye i-XLR imiselwe +4 dBu.

Ngeempawu ezilinganiselayo, isibonakaliso se-HOT (+) esivela kumthombo wakho kufuneka siqhagamshelwe kwi-tip ye-T / R / S ikhonkco okanye i-Pin 2 yegalelo le-XLR njengoko kuboniswe kuMzobo A. I-"COLD" (-) isignali kufuneka ixhunywe kwi-Pin 3 ye-XLR okanye "Ring" ye-T / R / S ikhonkco. Ukunqanda iilophu zomhlaba, qhagamshela i-SHIELD ekupheleni komthombo kodwa kungekhona kwigalelo leLSR.
Phawula: I-LSR12P isebenzisa kuphela amagalelo kunye neziphumo ze-XLR.

Imithombo engalungelelananga
Xa usebenzisa imithombo engalungelelananga, kukho amathuba amaninzi okwazisa iilophu zomhlaba kwisixokelelwano.
I-LSR28P kunye ne-12P zibonelela ngeendlela ezininzi zokunceda ukunciphisa iingxaki ezinokubakho ngezixhobo ezingalungelelananga.

Ngelixa kukho ukudityaniswa kwe-HOT kunye ne-GROUND / SHIELD kuphela kwimithombo engalungelelananga, kuyacetyiswa ukuba kusetyenziswe intambo ephothiweyo ekumgangatho ophezulu. Umzobo B ubonisa umthombo ongalinganiyo oqhagamshelwe kwigalelo elilinganayo le-XLR ye-monitor ye-LSR usebenzisa i-twisted pair cable. Qaphela ukuba ikhuselo liqhagamshelwe kwi-GROUND/SHIELD isinxibelelanisi kwigalelo le-LSR, kodwa hayi kumthombo. Oku kunciphisa ukuba nokwenzeka kokwazisa i-loop yomhlaba kwisixokelelwano.

Xa usebenzisa imiqondiso engalungelelananga kunye ne-LSR28P, kuyacetyiswa ukuba usebenzise i-1/4” Ingcebiso/Iringi/isiqhagamshelo semikhono Eli galelo lenzelwe ngokukodwa ukwamkela iindidi ezininzi zoqhagamshelwano olulungeleleneyo nolungalungelelananga i-C ibonisa xa usebenzisa i-1/4” I-Tip/Ring/Sleeve igalelo kufuneka lingabikho kwi-sleeve ye-GROUND kwaye ingabi ngumthombo we-sleeve ye-GROUND. ukusebenza.

Umzobo D unika iinkcukacha zokudityaniswa kusetyenziswa intambo ene-single-conductorelded eneTip/Ring/Sleeve plug ye-LSR28P input. Intambo yomqhubi omnye kufuneka isetyenziswe njengendlela yokugqibela, njengoko ibonelela kakhulu kwiingxaki. Umqondiso othi "HOT" (+) kufuneka uqhagamshelwe kwincam yeNcam yeNcam/yeRing/Sleeve. UMHLABA kufuneka uncanyathiselwe kwiRingi yeTip/Ring/Sleeve plug kwigalelo leLSR28P.

Umzobo u-E uchaza uxhulumaniso usebenzisa intambo engalinganiyo kunye neNgcaciso / i-Sleeve uxhulumaniso kwi-input ye-1/4. Kule modi, i-Ring kunye ne-Sleeve yegalelo le-LSR zifutshane ngeplagi ngokuzenzekelayo.
