Qhov tawm ntawm cov kais dej nres ntawm tus kais yuav tsum tau txuas nrog tus kais / splitter, vim tias qhov teeb liab ntawm cov kab lus tom ntej, yog li lub teeb liab hauv tag nrho cov kab yog sib npaug nrog kev siv cov teeb meem amplifier.
Coj mus rhaub yog nyob rau hauv cov ntaub ntawv ntawm cov zis tseem ceeb tshaj tawm cov khoom siv hluav taws xob hauv qab no cov khoom siv hluav taws xob tseem ceeb, nws tseem muaj qhov chaw nres nkoj hluav taws xob tseem ceeb
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov khoom siv sib cav yog tias nws tuaj yeem daws cov teeb meem ntawm cov khoom siv zoo tib yam nkaus, uas muaj peev xwm daws tau qhov teeb meem zoo ib yam nkaus, uas muaj peev xwm daws tau cov khoom siv ua kom pom kev vim muaj ib qho chaw kos npe hauv qhov project. Ntawm lub interface ntaus ntawv, lub splitter yog ib qho kev tswj hwm uas faib tawm audio thiab video teeb liab rau ntau cov khoom siv cov khoom siv lossis cov khoom tawm. Nws yog ib qho cuab yeej nyob rau hauv daim ntawv ntawm ib qho interface uas tshwj xeeb hauv kev faib cov cim.
