Txhim Kho Kev Ua Zoo Tshaj nrog Kev Tshaj Tawm DAC
Hauv ntiaj teb cov suab digital, qhov kev ua si kawg yog qhov digital digital-to-analog converter , los yog DAC. Cov me me, cov ntawv teev me me tsis yog ua rau cov neeg ua haujlwm hauv disc los yog lub computer thiab yog cov yuam sij rau kev hloov cov billions ntawm 0s thiab 1s ntawm lub suab teeb meem (piv txwv li ntawm CD lossis DVD) mus rau lub suab paj nruag zoo ib yam uas ncaj ncees rau lub suab qub.
DAC yog qhov tseem ceeb ntawm cov suab digital. Kev txhim kho sai sai hauv technology thiab nce hauv cov koob npe ntawm mobile / computer audio tau tsav cov neeg xav tau rau sab nraud DACs. Cov khoom no yog tsim los txhawb cov kev ua suab paj nruag, cov tshuab computer, kev ua si , thiab lwm qhov chaw suab .
Cambridge suab DacMagic
DacMagic 100 yog ib qho kev tawm sab nraud DAC muaj Cambridge Audio, lub chaw tsim tshuaj paus UK. Txij xyoo 1968, Cambridge Audio tau muaj nruab nrab-rau AV high-end AV Cheebtsam, cov khoom siv, thiab lub iPad tshuab. DacMagic 100 yog ib qho me me, ntsuas txog 1/3 qhov loj ntawm ib tus neeg laus los yog DVD player. Nws muaj peev xwm muab verticically los yog horizontally siv cov khoom siv roj hmab ntawm qhov chaw. Thaum sib txuas nrog, DacMagic 100 ua cov txheej txheem digital-rau-analog hloov, uas feem ntau yog ua los ntawm ib cov neeg siv ntawv disc, qus console, suab paj nruag neeg rau zaub mov, lossis PC.
DacMagic 100 tau nkag mus rau peb qhov chaw suab - ib qho khoom siv rau kev kho qhov muag (Toslink) thiab ob leeg rau coaxial S / PDIF , thiab ib qho USB input rau kev txuas mus rau USB lub tso tawm ntawm lub PC lossis MAC lub computer. Analog outputs muaj kev sib txuas ua ke ( RCA ) thiab kev sib npaug ntawm kab sib txuas (XLR). Ib qho kev xeem dhau (nrog Toslink thiab S / PDIF) yog muab los txuas rau lub suab digital recorder.
A (Luv) Zaj Lus Qhia Hauv Cov Nrov Digital
DacMagic 100 'upsamples' ib lub teeb tawm suab ntawm 16-ntsis / 44.1 kHz mus txog 24-ntsis / 192 kHz. Txawm hais tias muaj kev sib tham txog digital audio tshaj li qhov tshooj no, txaus los hais tias qhov nce ntawm tus nqi qis ntawm 16 txog 24-npav nce qhov loj ntawm txhua tus qauv coj los ua, thiab ua kom tiav cov teeb liab ntawm 44.1 kHz (44,100 kuaj ib pliag) mus rau 192 kHz (192,000 kuaj tauj ib zaug), ua rau kom muaj nuj nqis digital pulses sampled ib ob. Qhov kev tshwm sim muaj ntau dua dynamic ntau thiab ncua kev ua haujlwm siab ntawm cov lus tso tawm analog.
Lwm qhov tseem ceeb yog 32-ntsis teeb liab qhov kev tsim los txo cov teeb liab 'jitter.' Jitter yog ib qho teeb meem ntawm cov suab uas muaj feem rau lub sij hawm poob ntawm cov pulses, tej zaum tau piav raws li 'shaky pulses.' Ib lub suab hais meej, piv txwv li 32-ntsis processor, pab txo cov teeb liab jitter thiab pab txhim kho kev qhia kom paub meej thiab teeb liab. Lwm cov cim tseem ceeb ntawm DacMagic 100 muaj xws li ib qho piv txwv tus qauv qis (32, 44.1, 48, 88.2, thiab 96 kHz sampling rates) thiab peb cov ntxaij lim dej (L) uas tau kho raws li kev nyiam mloog. Pem taub hau theem tshooj theem hloov qhov kev pab cuam yog muab rau cov ntaub ntawv pov thawj.
Muaj Txaus Nrog Kev Tshawb Fawb Txog Science - Puas yog DacMagic Ua Haujlwm Zoo?
