M-Audio M-Track Duo - audio interface
M-Audio, nrog qhov zoo sib xws, npe nws cov khoom tom ntej M-Track. Cov tiam tshiab ntawm cov interfaces no ntxias nrog tus nqi qis heev, Crystal preamps thiab bundled software.
Nws yog ib qho nyuaj rau kev xav, tab sis tag nrho 2x2 suab interface zoo li M-Track Duo tam sim no pheej yig dua li qee qhov guitar cables! Txawm hais tias lub ntiaj teb tau nce mus rau brink, los yog muaj qee qhov zais cia hauv cov cuab yeej no uas nyuaj rau kev nkag siab. Hmoov zoo, tsis yog. Ib qho yooj yim piav qhia rau tus nqi qis yog siv lub codec uas tseem txhawb nqa USB hloov. Yog li, peb muaj ib qho analog-rau-digital, digital-rau-analog converter thiab lub processor uas tswj lawv txoj haujlwm nyob rau hauv daim ntawv ntawm ib qho kev sib xyaw ua ke, uas nyob rau hauv rooj plaub no yog Burr Brown PCM2900. Txawm li cas los xij, versatility, ntxiv rau qhov yooj yim thiab tus nqi qis ntawm tag nrho cov kev daws teeb meem, yog txuam nrog qee qhov kev txwv.
Bits 16
Thawj yog kev siv USB 1.1 raws tu qauv, ib qho kev hloov pauv ntawm lub xeev no yog 16-ntsis hloov dua siab tshiab nrog cov qauv mus txog 48 kHz. Qhov no tshwm sim nyob rau hauv ib tug dynamic ntau yam uas tsis pub tshaj 89 dB nyob rau hauv analog-rau-digital hom, thiab 93 dB nyob rau hauv digital-rau-analog hom. Qhov no tsawg kawg yog 10 dB tsawg dua li feem ntau siv 24-ntsis kev daws teeb meem niaj hnub no.
Txawm li cas los xij, yog tias peb xav tias cov cuab yeej siv tsuas yog siv rau kev kaw hauv tsev studio, ces 16-ntsis kaw yuav tsis yog qhov txwv loj rau peb. Tom qab tag nrho, qhov nruab nrab ntawm lub suab nrov, cuam tshuam thiab ntau hom suab nrov, txawm tias nyob hauv ib lub tsev nyob ntsiag to, yog kwv yees li 40 dB SPL. Ntawm tag nrho 120 dB dynamic ntau ntawm tib neeg lub suab, tsuas yog 80 dB muaj rau peb. Lub microphone thiab preamplifier yuav ntxiv tsawg kawg 30 dB ntawm lawv tus kheej lub suab nrov, yog li qhov tseeb dynamic ntau ntawm cov kaw lus tseem ceeb yog qhov nruab nrab ntawm 50-60 dB.
Yog li vim li cas 24-ntsis suav siv? Rau ntau lub taub hau thiab kev ua tau zoo nyob rau hauv ib puag ncig kev ua haujlwm ntsiag to ntau dua nrog lub suab nrov tsis tshua zoo siab microphones thiab lub suab zoo tshaj lub suab preamps. Txawm li cas los xij, muaj tsawg kawg yog ob peb lub laj thawj vim li cas 16-ntsis kaw hauv tsev studio yuav tsis muaj kev cuam tshuam kom tau txais kev txaus siab rau kev kaw suab.
tsim
Microphone preamps yog ua tib zoo tsim cov qauv tsim nrog lub transistor input thiab voltage nce siv los ntawm op-amp. Ntawm qhov tod tes, cov kab inputs muaj ib txoj hauv kev nthuav dav, thiab cov khoom siv guitar muaj FET tsis. Cov kab tawm tawm yog hluav taws xob sib npaug thiab buffered, thaum lub mloog pob ntseg tso tawm muaj ib qho amplifier cais. Tag nrho cov no tsim cov duab ntawm qhov yooj yim tab sis kev xav interface nrog ob lub tswv yim thoob ntiaj teb, ob kab tawm thiab lub mloog pob ntseg. Hauv kev saib xyuas kho vajtse hom, peb tuaj yeem hloov pauv ntawm cov kev mloog mloog los ntawm hauv DAW software; los ntawm mono inputs (ob leeg hnov ntawm ob lub channel) thiab DAW; thiab hauv lub tso suab (ib sab laug, ib txoj cai) thiab DAW. Txawm li cas los xij, koj tsis tuaj yeem sib xyaw qhov sib npaug ntawm cov teeb liab tawm tswv yim thiab cov teeb liab tom qab.
Txawm li cas los xij ntawm kev saib xyuas, cov khoom siv raug xa mus rau USB thiab pom hauv DAW cov kev pab cuam raws li ob-channel USB Audio Codec chaw nres nkoj. Lub combo inputs default rau mic hom thaum lub XLR plug txuas nrog, thaum tig rau 6,3 hli TS los yog TRS plug activates kab los yog ntsuas hom, nyob ntawm seb qhov hloov chaw.
Tag nrho lub cev ntawm lub interface yog ua los ntawm yas, thiab cov potentiometers nyob rau hauv conical recesses. Lawv rubberized npog ua kom tuav tau yooj yim dua. Cov input jacks yog txuas mus rau lub vaj huam sib luag, thiab cov zis jacks tsis zoo li wobble ntau dhau. Tag nrho cov keyboards ua haujlwm du thiab ntseeg tau. Cov LEDs nyob rau pem hauv ntej vaj huam sib luag teeb liab muaj thiab distortion ntawm lub input teeb liab thiab ua kom lub phantom voltage ntau rau ob qho tib si inputs.
Cov cuab yeej siv los ntawm USB chaw nres nkoj. Peb txuas lawv rau Mac khoos phis tawj yam tsis tas yuav teeb tsa cov tsav tsheb, thiab nyob rau hauv rooj plaub ntawm Windows, ASIO cov tsav tsheb tuaj yeem rub tawm los ntawm cov chaw tsim khoom lub vev xaib.
Ntawm kev xyaum
Tsis muaj lub hwj chim-on qhia ntawm lub interface, tab sis qhov no tuaj yeem kuaj xyuas los ntawm lub sijhawm ua kom lub zog phantom rau cov khoom siv. Qhov kev hloov kho ntawm lub microphone input rhiab heev yog kwv yees li 55 dB. Kev tswj kom zoo ntawm DAW khiav nrog lub suab nrov-dhau condenser microphone teeb liab tuaj yeem tau los ntawm kev teeb tsa qhov nce mus rau kwv yees li 75% ntawm qhov kev hloov kho. Nyob rau hauv cov ntaub ntawv ntawm hluav taws xob guitars, nws yuav yog, nyob ntawm seb qhov ntsuas, los ntawm 10 mus rau 50%. Cov kab tawm tswv yim muaj qhov rhiab heev 10 dB qis dua li ntawm microphone input. Cov theem ntawm distortion thiab suab nrov ntawm cov zis yog -16 dB raug rau 93-ntsis interfaces, yog li txhua yam yog raws li nws yuav tsum muaj nyob rau hauv no hais txog.
Ib qho teeb meem yuav tshwm sim thaum mloog lub teeb liab los ntawm lub microphone inputs - hauv lub mloog pob ntseg, tsis hais qhov chaw, nws yuav nco ntsoov. Qhov no yog ib qho teeb meem tshwm sim nrog feem ntau pheej yig suab interfaces, yog li kuv yuav tsis fuss txog nws, txawm hais tias nws yeej yuav tsis ua rau koj txoj hauj lwm yooj yim dua.
Mic preamps muaj qhov ntse dhia hauv kev nkag siab ntawm qhov kawg ntawm kev tswj ntau yam, thiab Tau txais cov pob tw viav vias ntau dhau - qhov no yog lwm qhov kev zoo nkauj ntawm cov kev daws teeb meem pheej yig dua. Lub mloog pob ntseg tso zis yog tib lub teeb liab raws li cov kab tawm, tsuas yog peb tuaj yeem kho lawv cov qib ntawm nws tus kheej.
Muaj cov software pob suav nrog 20 Avid plug-ins, Xpand!2 virtual suab module thiab Kaum Ib Hlis Lite guitar amp emulation plug-in.
Summation
M-Track Duo yog qhov ua tau zoo, ua haujlwm tau zoo thiab tus nqi qis heev uas tso cai rau koj sau cov microphones thiab cov cuab yeej hluav taws xob thiab hluav taws xob hauv koj lub tsev studio. Tsis muaj foob pob hluav taws lossis cov kev daws teeb meem tshwj xeeb, tab sis txhua yam uas tso cai rau koj ua tiav txoj haujlwm nrog kev siv zog tsawg tshaj plaws. Ua ntej, peb tuaj yeem siv XLR, TRS thiab TS connectors, uas tsis yog li pom tseeb hauv cov nqi no. Muaj cov khoom tsim tau txaus preamplifiers, lub mloog pob ntseg tsim tau zoo thiab muaj peev xwm los txuas cov neeg saib xyuas yam tsis muaj kev hloov pauv thiab vias.
Kev txwv hauv ntau daim ntawv thov yuav yog 16-ntsis hloov dua siab tshiab daws teeb meem thiab qhov nruab nrab zoo tswj cov teeb liab los ntawm microphone inputs. Tej zaum koj yuav muaj kev tsis ntseeg txog kev ruaj ntseg ntawm kev tswj hwm, thiab koj yuav tsum tsis txhob teeb tsa lawv txhua txoj hauv kev thaum mloog. Txawm li cas los xij, cov no tsis yog qhov tsis zoo uas lwm cov khoom lag luam, txawm tias kim dua, yuav yog dawb los ntawm.
Tsis muaj kev tsis ntseeg tias nyob rau hauv daim ntawv ntawm M-Track Duo peb muaj ib qho ntawm cov pheej yig tshaj 2x2 suab interfaces ntawm lub khw, lub functionality uas yuav tsis nyob rau hauv qhov tsawg kawg nkaus txwv txoj kev loj hlob ntawm nws cov neeg siv txuj ci los yog muaj peev xwm los tsim suab paj nruag. hauv tsev studio.
