System tso suab

Xyoo 1958, lwm cov ntaub ntawv loj heev Columbia tso thawj cov ntaub ntawv tso suab. Txog rau tam sim no, tsuas yog monophonic albums tau paub, piv txwv li cov uas txhua lub suab raug kaw hauv ib lub channel. Lub stereo system tau cais lub suab rau hauv ob lub channel.

Cov yam ntxwv ntawm lub suab reproduced

Cov ntaub ntawv yas muaj grooves uas muaj qhov tsis sib xws. Nws yog vim cov irregularities uas rab koob yog ua kom vibrate. Cov duab ntawm cov irregularities yog xws li cov vibrations ntawm lub stylus recreate lub acoustic teeb liab kaw nyob rau hauv lub disc thaum nws kaw. Contrary to tshwm sim, qhov no technology yog heev meej thiab meej. Qhov dav ntawm qhov zawj no tsuas yog 60 micrometers.

RIAA kev kho

Yog tias peb xav kaw lub suab nrog cov yam ntxwv ntawm cov ntaub ntawv yas, peb yuav muaj cov khoom me me ntawm lub disc vim tias qhov tsawg zaus yuav siv ntau qhov chaw. Yog li ntawd, ua ntej sau cov ntaub ntawv yas, cov lus teb zaus ntawm cov teeb liab hloov raws li qhov hu ua RIAA kho. Qhov kev kho no muaj nyob rau hauv kev ua kom tsis muaj zog ntawm qhov qis thiab nce qhov ntau zaus ua ntej cov txheej txheem ntawm kev txiav cov ntaub ntawv yas. Ua tsaug rau qhov no, cov grooves ntawm lub disc tuaj yeem nqaim dua thiab peb tuaj yeem txuag tau ntau cov khoom siv suab ntawm lub disc.

Preamplifier

Lub preamplifier yuav tsum tau siv los rov qab qhov poob qis zaus uas txwv tsis pub kaw los ntawm kev siv RIAA sib npaug. Yog li ntawd, txhawm rau mloog cov ntaub ntawv yas, peb yuav tsum muaj phono qhov (socket) nyob rau hauv lub amplifier. Yog tias peb lub amplifier tsis tau nruab nrog lub qhov (socket), peb yuav tsum yuav ib qho ntxiv preamplifier nrog lub qhov (socket).

Summation

Cov thev naus laus zis meej uas tau tsim ntau xyoo dhau los thiab uas tau siv los ntawm ntau lab tus audiophiles hauv kev hlub nrog cov suab analogue rau hnub no yuav yog qhov xav tsis thoob. Hauv qhov ntu no, peb tau tsom mus rau feem ntau ntawm kev txhim kho cov ntaub ntawv yas, hauv ntu tom ntej peb yuav tsom mus ntxiv rau cov ntsiab lus tseem ceeb ntawm turntable thiab nws txoj kev loj hlob.
