Tam sim no, muaj cov lag luam loj, hom, chav kawm thiab lub zog ntawm cov tso suab.
Lub ntsiab tsis tseem ceeb thaum xaiv lub suab txuas ntxiv rau cov neeg hais lus lossis, raws li nws yog qhov tseeb, lub nruab suab (AC) yog:
- Suab paj nruag (Suab paj nruag), txwv tsis pub muaj txheej txheem (Programme) fais fab (W);
- kev tawm tsam (Ohm).
Software hwj chim, yog dab tsi?
Txhua tus hais lus muaj 3 lub zog: lub zog loj tshaj (Peac), Qhov Haujlwm (suab paj nruag) lub zog thiab RMS lub zog (rau qee lub sijhawm nrog nth zog, lub suab paj nruag liab liab tau xa mus rau tus hais lus, qhov no yog qhov tseem ceeb npaum li cas thiab nws qhov kev ua haujlwm raug kuaj xyuas)). Lub teeb liab rau xam lub zog programmed yog nthuav tawm nyob rau hauv daim ntawv ntawm nruab nrab suab paj nruag teeb liab, nrog attenuation thiab peaks. Xws li lub teeb liab, hauv kev sib piv rau lub suab nrov liab qab, nws yuav yooj yim rau kev yug me nyuam los ntawm tus neeg hais lus thiab nws ua kom tsawg dua Nws yog los ntawm RMS lub zog uas qhov kev zov me nyuam lub zog tau xam, uas yog kwv yees li ob npaug ntawm RMS. Lwm 2 lub sijhawm ntxiv software yog lub zog siab tshaj plaws, tab sis yuav kom xaiv lub suab nrov koj yuav tsum tsis txhob mloog nws, vim nws tsuas kav ntev li ob peb milliseconds ntawm tus ntuav lus xwb.
Raws li txoj cai, tag nrho 3 hom zog tau sau rau hauv daim ntawv hla tebchaws AC, tab sis yog tias ib qho qhia, tom qab ntawd nws tsis yooj yim los xam qhov program fais fab. Nws tseem tau suav los ntawm lwm cov kev ntsuas: AES, EIAJ, thiab lwm yam.
4 lossis 8 ohms yog qhov cuam tshuam ntawm feem ntau ntawm cov tshuab. Txhawm rau xaiv qhov kom zoo amplifier, mloog yuav tsum tau them rau ntau npaum li cas lub zog amplifier tuaj yeem xa thiab ntawm dab tsi ua haujlwm. Qhov no feem ntau tau qhia hauv nws lub luag haujlwm. Koj tuaj yeem txuas cov lus hauv kev sib txig (los ntawm cov khoom sib txuas tshwj xeeb).
R tag nrho = (R1xR2) / (R1 + R2) yog tus qauv rau xam tag nrho cov quab yuam ntawm 2 tus neeg txuas nrog sib txuas lus, qhov twg R1 thiab R2 yog qhov tawm tsam ntawm cov kab ke. Nrog tib qho kev tawm tsam rau ob qho kev hais lus, koj tuaj yeem faib cov tsis kam ntawm ib qho los ntawm ob. Txuas nrog lub zog txuas rau lub zog nrog ib qho cuam tshuam tsawg tshaj qhov tsawg kawg nkaus rau nws tau txwv tsis pub! Txhua zaus yuav tsum kuaj cov amplifier impedance thiab tag nrho impedance ntawm tus neeg txuas nrog raws li daim ntawv hla tebchaws.
Yog hais tias lub suab nrov dua nyob rau hauv hom choj, tom qab ntawd 2 txoj kev sib txuas ua ke thiab qhov tshwm sim cuam tshuam. Txhua lub suab nrov tau tsuas muaj ib qho RMS zog thiab nws yog rau nws tus hais lus tau xaiv. Cov lus tsis pub tshaj tawm yuav tsum tsis raug tso cai ua haujlwm nrog "xoob" ntau dhau qhov ua tiav, nyob rau hauv rooj plaub ntawd txawm tias tsis muaj zog yuav cuam tshuam cov lus!
