Qhov kev sib raug zoo ntawmtus hais lusLub Hwj Chim (Wattage)thiabimpedance (Ohms)yog qhov tseem ceeb ntawm kev tsim qauv audio .xdec lus qhia koj cov kev qhia tshwj xeeb:
Lub Zog & Cuam Tshuam Kev Sib Raug Zoo
OHM txoj cai
Hwj chim (p) {= voltage (v²) / impedance (z)
Rau ib qho muab nthuav dav voltage voltage tso zis:
▪ Qis dua impedance (e.g., 4Ω) → Lub Zog Zog Zog Kos
▪ Siab dua impedance (e.g., 8Ω) → Txo Cov Zog Hluav Taws Xob
Qhov tseem ceeb sib txuas
Amplifier Compatibility:
Feem ntau cov hluav taws xob nthuav dav hluav taws xob tawm ntawm cov qauv cuam tshuam (piv txwv li, 50W @ 8N → yuav xa tawm ~ 80W @ 4N).
Tshaj dhau tus amp tam sim no muaj peev xwm ntawm cov kev pheej hmoo tsis txaus ntseeg clipping / overheating.
Kev lag luam ua lag luam ua haujlwm:
Tsawg-z hais lus (4ω) Kos zog ntau dua tab sis thov txau efficonomiciciency (DB / m).
High-Z hais lus (8ω +) muaj ntau yam hauv cov suab kom txo qis dua cov kev poob ntev khiav.
Kev txiav txim siab tseem ceeb
Impedance nkhaus: Qhov yuam kev tiag tiag sib txawv nrog zaus (piv txwv li, "8ω nominal" hais lus yuav poob rau 5ω ntawm resonance).
Lub Zog Tuav Tes: Hais lus kub / tshuab txwv (rms thiab lub zog siab) yuav tsum phim amp tso zis.
Cov Tswv Cuab cuam tshuam
| Xwm txheej | Ua rau | Tus yam ntxwv |
|---|---|---|
| 8ω Hais Lus Ntawm 4ω AMP Kais | Underpowered (muaj kev nyab xeeb) | Amp muab • 50% rated zog |
| 4ω Hais Lus Ntawm 8TP | Overcurrent pheej hmoo | Tej zaum yuav ua rau Circuit Txwv |
| Mismatched impedance | Cov lus teb tsis zoo | Bass Roll-OFF ntawm Impedance Dips |
Cov Kev Cai Tsim
Aud suab: Feem ntau 6-8} ω rau kev ua haujlwm ruaj khov.
Tsheb suab: Feem ntau 4ω kom ua rau lub zog ua siab ntev los ntawm 12v tshuab.
Pro Suab: Siv tau 70v / 100v High-Z system system rau faib cov teeb tsa.
Tsab ntawv: XDEC Speauekr qhia ib txwm txheeb xyuas ob leeg hais lus yuam (ω) thiab amplifier tus thauj khoom tsawg kawg ua ntej ua khub.
