Cov khoom ntawm lub tso suab tso suab tuaj yeem ua rau tsis meej pem rau cov uas nyuam qhuav pib muab tso ua ke. Dab tsi yog qhov txawv ntawm receivers thiab amplifiers? Vim li cas koj thiaj xaiv kom muaj cov txheej txheem ntawm cov khoom sib cais, thiab lawv txhua tus ua li cas? Ntawm no yog ib qho kev qhia txog cov khoom ntawm lub tshuab suab kom koj tuaj yeem nkag siab zoo dua lub luag haujlwm txhua tus ua si hauv koj qhov kev mloog.
Tus neeg txais
A receiver yog ib qho ua ke ntawm peb yam: lub amplifier, lub chaw tswj, thiab AM / FM tuner. Lub receiver yog qhov nruab nrab ntawm lub kaw lus, qhov twg tag nrho cov suab thiab video Cheebtsam thiab hais lus yuav txuas thiab tswj. Lub receiver txhawb lub suab, tau txais AM / FM chaw nres tsheb, xaiv qhov chaw mloog thiab / lossis saib (CD, DVD, Daim kab xev, thiab lwm yam) thiab kho lub suab zoo thiab lwm yam kev nyiam mloog. Muaj ntau lub receivers xaiv los ntawm, nrog rau lub tso suab thiab multichannel home theatre receivers. Koj qhov kev txiav txim siab yuav tsum yog nyob ntawm seb koj yuav siv lub receiver li cas. Piv txwv li, yog tias koj nyiam mloog suab paj nruag ntau dua li saib cov yeeb yaj kiab, tej zaum koj yuav tsis xav tau ntau tus neeg txais xov tooj. Lub tso suab receiver thiab CD lossis DVD player thiab ob tus neeg hais lus yuav yog qhov kev xaiv zoo dua.
Integrated Amplifiers
Ib qho kev sib xyaw amp zoo li tus txais tsis muaj AM / FM tuner. Ib qho yooj yim integrated amplifier combines ib tug ob-channel los yog multichannel amp nrog ib tug pre-amplifier (tseem hu ua ib tug tswj amp) rau xaiv lub suab thiab kev khiav hauj lwm suab tswj. Integrated amplifiers feem ntau nrog ib tug cais AM/FM tuner.
cais Cheebtsam: Pre-Amplifiers thiab Fais Amplifiers
Ntau tus neeg nyiam suab nrov thiab cov neeg mloog kev ntxub ntxaug nyiam cov khoom sib cais vim tias lawv muab cov suab zoo tshaj plaws thiab txhua lub ntsiab lus tau ua kom zoo rau nws txoj haujlwm tshwj xeeb. Tsis tas li ntawd, vim tias lawv yog cov khoom sib cais, muaj tsawg dua kev cuam tshuam ntawm pre-amp thiab theem siab dua tam sim no ntawm lub hwj chim amp.
Kev pabcuam lossis kho kuj tseem ceeb, yog tias tsim nyog. Yog tias ib feem ntawm a / v receiver xav tau kev kho, tag nrho cov khoom yuav tsum raug coj mus rau qhov chaw pabcuam, uas tsis muaj tseeb ntawm kev sib cais. Nws kuj tseem yooj yim dua los txhim kho cov khoom sib cais. Yog tias koj nyiam lub amplifier ua ntej / processor, tab sis xav tau ntau lub zog amplifier koj tuaj yeem yuav lub amp zoo dua yam tsis tau hloov lub pre-amp.
kab hauv qab
Ib lub tshuab hluav taws xob ua ntej tseem hu ua lub tshuab hluav taws xob tswj hwm vim tias nws yog qhov chaw txhua yam txuas nrog thiab tswj. Lub pre-amp muab ib qho me me ntawm amplification, tsuas yog txaus los xa cov teeb liab mus rau lub hwj chim amplifier, uas ua kom lub teeb liab txaus rau lub hwj chim hais lus. Cov txais tau zoo heev, tab sis yog tias koj xav tau qhov zoo tshaj plaws, tsis muaj kev cuam tshuam, xav txog cov khoom sib cais.
Power Amplifiers
Lub zog amplifier muab cov hluav taws xob tam sim no los tsav cov hais lus nrov thiab lawv muaj nyob rau hauv ob-channel lossis ntau qhov kev teeb tsa multichannel. Lub hwj chim amps yog qhov kawg ntawm cov khoom siv hauv lub suab ua ntej lub suab nrov thiab yuav tsum tau sib phim nrog cov peev txheej ntawm cov neeg hais lus. Feem ntau, lub hwj chim tso zis ntawm lub amp yuav tsum tau zoo sib xws nrog lub zog tuav lub peev xwm ntawm cov neeg hais lus.
