M-Audio M-Track Duo - odhiyo interface

M-Audio, ine kuwirirana kunoshamisa, inodana zvigadzirwa zvayo zvinotevera M-Track. Chizvarwa chazvino cheaya mainterface anokwezva nemutengo wakaderera, Crystal preamps uye bundled software.

Zvakaoma kufungidzira, asi yakazara 2x2 odhiyo interface seM-Track Duo ikozvino yakachipa kupfuura mamwe tambo dzegitare! Pamwe nyika yamukira kumawere, kana kuti pane chakavanzika mumudziyo uyu chinonetsa kunzwisisa. Sezvineiwo, kana. Tsananguro yakapusa yemutengo wakaderera ndiko kushandiswa kwecodec inotsigirawo USB kutamiswa. Saka, isu tine analog-to-digital, digital-to-analog converter uye processor inodzora basa ravo muchimiro chechikamu chimwe chete chakabatanidzwa, icho munyaya iyi Burr Brown PCM2900. Zvisinei, kushandiswa kwakasiyana-siyana, kuwedzera kune nyore uye mutengo wakaderera wemhinduro yose, inosanganiswa nemimwe mipimo.

Zvishoma 16

Yekutanga ndeyekushandiswa kweiyo USB 1.1 protocol, yakabva kune iyi mamiriro ezvinhu ndeye 16-bit shanduko ine sampling inosvika 48 kHz. Izvi zvinoita kuti pave nehuwandu hunochinja husingapfuuri 89 dB muanalog-to-digital mode, uye 93 dB mu digital-to-analog mode. Iyi ingangoita gumi dB yakaderera pane inowanzo shandiswa 10-bit mhinduro nhasi.

Nekudaro, kana isu tichifungidzira kuti mudziyo uchashandiswa chete kurekodha mu studio yekumba, ipapo 16-bit kurekodha haizove yakanyanya kuganhurirwa kwatiri. Mushure mezvose, avhareji nhanho yeruzha, kupindira uye akasiyana siyana e ambient ruzha, kunyangwe mukamuri yakanyarara, ingangoita makumi mana dB SPL. Pakati pese 40 dB inoshanduka yerudzi rwemunhu, chete makumi masere dB ndiyo inowanikwa kwatiri. Iyo maikorofoni uye preamplifier ichawedzera inokwana makumi matatu dB yeruzha rwavo, kuitira kuti iyo chaiyo inoshanduka rekodhi rekodhi inobatsira chiratidzo chiri paavhareji 120-80 dB.

Saka nei 24-bit computing ichishandiswa? Kuti uwane mamwe headroom uye kuita munzvimbo yakanyarara nyanzvi studio nharaunda ine isinganyanye ruzha rwemhando yepamusoro maikorofoni uye yepamusoro ruzha rwekuumba preamps. Nekudaro, pane zvingangoita zvikonzero zvishoma nei 16-bit kurekodha mu studio yekumba isingazove chipingamupinyi pakuwana inogutsa inonzwika kurekodha.

design

Maikorofoni preamp yakanyatso gadzirwa madhizaini ane transistor yekupinda uye voltage kuwana inoitwa neop-amp. Kune rimwe divi, mitsetse yemitsara ine yakaparadzana nzira yekusimudzira, uye magitare ekuisa ane FET buffer. Iyo mitsetse inobuda ndeyemagetsi yakaenzana uye yakavharwa, nepo iyo mahedhifoni inobuda ine yakaparadzana amplifier. Zvese izvi zvinogadzira mufananidzo weyakapfava asi ine fungidziro ine maviri epasirese ekuisa, maviri mitsara inobuda uye yehedhifoni inobuda. Mune hardware yekutarisa maitiro, isu tinogona chete chinja pakati pekuteerera zvikamu kubva mukati meDAW software; kubva kumono inputs (zvese zvinonzwika pamatanho ese) uye DAW; uye mustereo (mumwe kuruboshwe, mumwe kurudyi) uye DAW. Nekudaro, haugone kusanganisa zviyero zvechiratidzo chekuisa uye chiratidzo chekumashure.

Zvisinei nemasetirwo ekutarisa, izvo zvinopinda zvinotumirwa ku USB uye zvinoonekwa muzvirongwa zveDAW senge-maviri-chiteshi USB Audio Codec port. Iyo combo inoisa default kune mic modhi kana XLR plug yakabatana, uchibatidza 6,3mm TS kana TRS plug inomutsa mutsara kana chiridzwa modhi, zvichienderana nekuchinja kwekuchinja.

Muviri wese weiyo interface wakagadzirwa nepurasitiki, uye iyo potentiometers iri muconical recesses. Zvivharo zvavo zvine rubberized zvinoita kuti kubata kuve nyore. Iwo majeki ekuisa anonamirwa zvakasimba kune panhizha, uye majeko ekubuda haaite kuzununguka zvakanyanya. Maswichi ese anoshanda zvakanaka uye akavimbika. Iwo maLED ari pamberi pepaneru anoratidza kuvepo uye kukanganisa kwechiratidzo chekupinza uye activation yeiyo phantom voltage yakajairika kune ese mapipu.

Chigadzirwa chacho chinofambiswa ne USB port. Isu tinozvibatanidza kumakomputa eMac pasina chikonzero chekuisa madhiraivha, uye mune yeWindows, madhiraivha eASIO anogona kutorwa kubva pawebhusaiti yemugadziri.

Pakuita

Iko hakuna simba-pachiratidzo pane iyo interface, asi izvi zvinogona kutariswa nechinguva chidiki activate phantom voltage yezvipimo. Iyo yekugadziridza huwandu hweiyo maikorofoni yekuisa senitivity inosvika makumi mashanu neshanu dB. Kudzora kwakaringana kweiyo DAW track ine yakajairwa izwi-pamusoro condenser maikorofoni siginecha inogona kuwanikwa nekuseta iyo pfuma inosvika makumi manomwe neshanu muzana eiyo gadziriso renji. Panyaya yemagitare emagetsi, ichave, zvichienderana nechiridzwa, kubva pa55 kusvika ku75%. Iyo yekuisa mutsetse ine senitivity 10 dB yakaderera pane iyo yekuisa maikorofoni. Chiyero chekukanganisa uye ruzha pane zvakabuda ndeye -50 dB yakajairika kune 10-bit interfaces, saka zvese zviri sezvazvinofanira kuita mune izvi.

Rimwe dambudziko rinogona kumuka kana uchiteerera chiratidzo kubva kune maikorofoni inopinza - mumahedhifoni, zvisinei nemagadzirirwo, inogara ichipotswa. Iri idambudziko rakajairwa neakawanda akachipa audio interfaces, saka ini handingaite nharo nezvazvo, kunyangwe hazvo zvisingaite kuti basa rako rive nyore.

Mic preamps ine kusvetuka kwakapinza mukunzwa kwakananga kumagumo ekudzora renji, uye Gain knobs anozunguza zvakanyanya - uku ndiko kumwe kunaka kwemhinduro dzakachipa. Iyo mahedhifoni inobuda chiratidzo chimwechete seyakabuda mutsetse, isu chete isu tinokwanisa kugadzirisa iwo mazinga takazvimirira.

Inowanikwa software bundle inosanganisira makumi maviri Avid plug-ins, Xpand!20 virtual sound module uye Eleven Lite gitare amp emulation plug-in.

Summation

M-Track Duo inoshanda, inoshanda uye yakaderera zvakanyanya mutengo interface iyo inokutendera iwe kurekodha maikorofoni uye zvemagetsi uye zvemagetsi zviridzwa mu studio yako yekumba. Iko hakuna mafireworks kana akasarudzika tekinoroji mhinduro, asi zvese zvinokutendera kuti upedze basa racho nekushomeka. Kutanga, isu tinogona kushandisa XLR, TRS uye TS zvibatanidza, izvo zvisiri pachena zvakanyanya mumutengo uyu. Kune akakwana anogadzira preamplifiers, inonyatso gadzira headphone amplifier uye kugona kubatanidza anoshanda monitors pasina chero adapta uye vias.

Muganho mune mamwe maapplication epamberi ichave 16-bit shanduko yekugadzirisa uye avhareji yemhando yekudzora kwechiratidzo kubva kune maikorofoni mapipu. Iwe unogona kunge uine kusahadzika nezve kugadzikana kwekuwana zvidzoreso, uye iwe unofanirwa kunzvenga kuamisa nzira yese panguva yekuteerera kunoshingaira. Nekudaro, izvi hazvisi zvisizvo izvo zvimwe zvigadzirwa, kunyangwe zvinodhura zvakanyanya, zvingave zvisina zvachose kubva.

Hapana mubvunzo kuti muchimiro cheM-Track Duo isu tine imwe yakachipa 2x2 audio interfaces pamusika, kushanda kwayo kusingazodzikisire kusimudzira kwetarenda remushandisi kana kugona kuburitsa mimhanzi. mu studio yekumba.
