Impedance: Nws yog hais txog qhov sib piv ntawm qhov voltage mus rau qhov tam sim no ntawm tus hais lus input teeb liab. Lub tswv yim impedance ntawm tus hais lus feem ntau muab faib ua ob hom: siab impedance thiab qis impedance. Lub impedance siab tshaj 16Ω yog siab impedance, thiab impedance qis dua 8Ω yog impedance tsawg. Tus qauv impedance ntawm tus hais lus yog 8Ω.
Tus hais lus impedance feem ntau yog txuam nrog lub hwj chim amplifier. Qhov ntau dua tus hais lus impedance, qhov tso zis qis dua, yog li tsis muaj 16Ω hais lus. Cov neeg hais lus hauv tsev impedance feem ntau yog 4-8Ω. Cov zis ntawm 4Ω yog ob zaug loj dua li ntawm 8Ω, tab sis qhov yuav tsum tau muaj rau lub hwj chim amplifier yog siab dua, uas yuav tsum tau ib tug loj tso zis tam sim no thiab tsawg nyob rau hauv tsis kam. Haum rau chav kawm A lub zog amplifier.
2Ω tsuas yog tsim rau lub tsheb horn impedance, vim lub tsheb horns tsis muaj bass thaj tsam, thiab cov kev cai rau lub hwj chim amplifiers tsis yog li ntawd. Ntev npaum li qhov ntsuas qhov tso zis muaj zog loj, nws tuaj yeem nruab nrog 2Ω hais lus, thiab lub zog tso zis yuav loj dua.
Lub tsheb horns tsuas yog haum rau 2-4Ω. Vim tias lub zog tso zis ntawm lub tsheb amplifier yog me me.
Yog tias nws tau nruab nrog 8Ω speaker, lub suab yuav me me heev.
