Thaum nws los txog raucov khoom siv suab, lub amplifier ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov zoo ntawm lub suab tag nrho. Ntawm ntau cov lus qhia uastxhais cov kev ua tau zoo ntawm lub amplifier, qhov ntau zaus teb yog ib qho ntawm cov kev ntsuas tseem ceeb tshaj plaws. Nkag siab txog qhov ntau zaus teb cuam tshuam li cassuab zootuaj yeem pab cov neeg nyiam mloog suab thiab cov neeg mloog dav dav txiav txim siab tau zoo thaum xaiv cov khoom siv suab.

Cov lus teb zaus yog dab tsi?

Cov lus teb zaus yog hais txog ntau yam zaus uas lub amplifier tuaj yeem tsim dua tshiab tau zoo. Feem ntau nws ntsuas hauv Hertz (Hz) thiab qhia ua ntau yam, xws li 20 Hz txog 20 kHz. Qhov ntau yam no npog cov spectrum ntawm cov zaus uas tib neeg hnov ​​​​​​tau thiab feem ntau suav tias yog los ntawm 20 Hz (qhov qis tshaj plaws ntawm lub bass) mus txog 20 kHz (qhov siab tshaj plaws treble). Lub amplifier nrog ntau zaus teb tau dav dua tuaj yeem tsim dua qhov spectrum dav dua, txhim kho qhov kev paub mloog zoo heev.

Qhov Tseem Ceeb ntawm Qhov Kev Teb Zaus

1. Kev Tsim Dua Bass: Qhov kawg qis ntawm cov zaus spectrum, feem ntau qis dua 100 Hz, yog qhov chaw uas cov zaus bass nyob. Lub amplifier uas tuaj yeem tsim cov zaus qis no kom raug yuav ua rau muaj suab nrov dua, ntau duakev paub suab zoo heev.Rau cov hom ntawv uas xav tauntses bass tob, xws li suab paj nruag hluav taws xob, hip-hop, thiab suab paj nruag classical, lub amplifier nrog lub zaus teb uas txuas mus txog 20 Hz tuaj yeem txhim kho lub suab zoo heev.

2. Kev Pom Tseeb Nruab Nrab: Cov zaus nruab nrab (kwv yees li 300 Hz txog 3 kHz) yog qhov tseem ceeb rau kev pom tseeb ntawm lub suab thiab lub suab ntuj ntawm cov twj paj nruag. Lub amplifier uas ua tau zoo hauv qhov ntau no ua kom ntseeg tau tias cov suab thiab cov twj paj nruagsuab meejthiab zoo li tiag tiag. Yog tias qhov zaus teb yog txwv rau qhov ntau no, lub suab yuav tsis meej thiab tsis meej, cuam tshuam rau kev mloog tag nrho.

3. Cov Lus Qhia Txog Lub Suab: Cov zaus siab, tshwj xeeb tshaj yog cov uas siab dua 3 kHz, pab txhawb rau cov lus qhia meej thiab meej ntawm lub suab. Cov twj paj nruag xws li cymbals, flutes, thiab violins tsim cov suab hauv qhov ntau no. Lub amplifier uas tuaj yeem rov ua dua cov zaus no kom raug tuaj yeem muab qhov chaw thiab cov lus qhia meej, txhim kho qhov zoo ntawm lub suab. Cov lus teb zaus tsis txaus hauv qhov ntau treble tuaj yeem ua rau lub suab tsis meej lossissuab tsis muaj sia.

Qhov kev teb zaus cuam tshuam li cas rau qhov zoo ntawm lub suab

Lub amplifier qhov zaus teb ntau yam cuam tshuam ncaj qha rau nws qhov zoo li cas rov ua dua ntau hom suabcov teeb liab suab.Nov yog qee txoj hauv kev tseem ceeb uas qhov zaus teb cuam tshuam rau lub suab zoo:

1. Kev Tsis Sib Haum thiab Xim: Yog tias lub amplifier tsis tuaj yeem tsim cov zaus qee yam, nws yuav ua rau muaj kev tsis sib haum lossis xim rau lub suab. Piv txwv li, yog tias lub amplifier tsis tuaj yeem tswj cov zaus qis zoo, nws yuav tsim cov bass tsis sib haum uas tsis meej. Qhov kev tsis sib haum no pom tseeb tshwj xeeb hauv cov nqe lus nyuaj uas ntau yam twj paj nruag ua si tib lub sijhawm.

2. Dynamic Range: Ibdynamic range ntawm lub amplifierhais txog qhov sib txawv ntawm cov ntim ntsiag to thiab nrov tshaj plaws uas nws tuaj yeem tsim tawm. Qhov ntau zaus teb dav dua feem ntau txhais tau tias muaj ntau yam dynamic ntau dua, uas tso cai rau lub amplifier los tswj cov nuances me me thiab cov crescendos muaj zog yam tsis muaj kev cuam tshuam. Lub peev xwm no yog qhov tseem ceeb rau cov hom ntawv uas vam khom kev sib piv dynamic, xws li suab paj nruag classical thiab jazz.

3. Kev Teb Theem: Kev teb zaus tsis yog hais txog qhov loj ntawm lub suab ntawm ntau zaus sib txawv xwb, tab sis kuj suav nrog kev teb theem, uas yog lub sijhawm ntawmsuab nthwv dejCov amplifiers uas tsis teb tau zoo yuav ua rau muaj teeb meem rau lub sijhawm, ua rau lub suab tsis sib xws lossis tsis sib xws. Qhov no tshwj xeeb tshaj yog qhov tsis zoo hauv kev teeb tsa stereo, qhov twg cov duab thiab lub suab raug yog qhov tseem ceeb rau ib qhokev mloog zoo heev.

4. Kev sib raug zoo nrog cov neeg hais lus: Qhov teb zaus ntawm lub amplifier kuj yuav tsum sib xws nrog cov neeg hais lus uas nws tsav. Yog tias lub amplifier muaj qhov teb zaus tsawg, nws yuav tsis siv tag nrho cov kev ua tau zoo ntawm lub hais lus zoo. Ntawm qhov tod tes, lub amplifier zoo nrog cov lus teb zaus dav tuaj yeem siv tag nrho cov kev ua tau zoo ntawm lub hais lus mus rau nws lub peev xwm siab tshaj plaws.

Xaiv Lub Amplifier Zoo

Thaum twgxaiv lub amplifier, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov ntau zaus teb nrog rau lwm cov lus qhia xws li tag nrho harmonic distortion (THD), signal-to-noise ratio (SNR), thiab lub zog tso zis. Lub amplifier ua tau zoo tsis yog tsuas yog muaj qhov teb zaus dav xwb tab sis kuj muaj qhov tsis sib xws tsawg thiabtso zis hluav taws xob siabkom tsav cov neeg hais lus tau zoo.

Rau cov neeg nyiam mloog suab paj nruag, nws raug pom zoo kom mloog cov amplifiers sib txawv hauv ib puag ncig uas tswj tau kom ntsuas lawv lub suab zoo. Ua tib zoo saib seb lub amplifier ua kom cov bass, mid-range, thiab treble frequencies zoo li cas. Lub amplifier zoo yuav tsum muab lub suab sib npaug thoob plaws tag nrho cov zaus spectrum, ua rau muaj kev paub mloog zoo.

Xaus lus

Hauv kev xaus, qhov ntau zaus teb ntawm lub amplifier yog qhov tseem ceeb uas cuam tshuam rau qhov zoo ntawm lub suab. Kev teb zaus dav dua tso cai rau kev tsim cov bass zoo dua, qhov nruab nrab meej, thiab cov ntsiab lus treble, tag nrho cov no pab txhawb rau kev mloog zoo dua thiab lom zem dua. Los ntawm kev nkag siab txog qhov tseem ceeb ntawm kev teb zaus, cov neeg siv khoom tuaj yeem txiav txim siab tau zoo thaum xaiv cov amplifiers, kom ntseeg tau tias lawv tau txais lub suab zoo tshaj plaws los ntawm lawv cov kab ke suab. Txawm tias koj yog tus mloog tsis tu ncua lossis tus neeg nyiam mloog suab paj nruag tiag tiag, kev mloog zoo rau qhov teb zaus tuaj yeem coj koj qhov kev paub suab mus rau qib siab tshiab.
