Saib xyuas KRK Rokit 5 G4 Studio
KRK Rokit yog undoubtedly ib qho ntawm cov neeg saib zoo tshaj plaws nyob rau hauv lub ntiaj teb no, siv nyob rau hauv tsev kaw studios thiab tshaj. G4 yog lawv tiam plaub. Cov kev hloov pauv hauv G3 yog qhov loj heev uas peb tuaj yeem tham txog cov khoom tshiab kiag li.
Txawm hais tias pawg saib xyuas suav nrog G4 series peb yuav pom plaub tus qauv, kuv hais tias kuv xav sim tsawg kawgс 5" woofer.
Ua ntej, kuv tsis ntseeg tias qhov zoo tshaj plaws bass reproduction nyob rau hauv cov chav me me uas cov peev nyiaj nyob ze cov neeg saib xyuas feem ntau siv. Kev nce lub woofer txoj kab uas hla, uas yog qee zaum cuam tshuam nrog kev txo qis zaus ntawm tus saib xyuas, tsis muaj kev nkag siab ntau hauv cov xwm txheej zoo li no, tsuas yog muab lub tswv yim ntawm cov ntses bass thaj tsam tsawg. Txawm li cas los xij, xws li ntses bass thaj tsam tseem tsis tuaj yeem tswj tau thiab ntau dua psychoacoustic tshwm sim tshaj cov ntaub ntawv suab zoo.
Lub DSP thaiv yog tswj los ntawm cov kua siv lead ua kua thiab lub encoder nrog lub khawm ua haujlwm. Lub encoder nws tus kheej kuj tso cai rau koj los kho cov tswv yim rhiab heev ntawm cov saib.
Qhov thib ob yog vim li cas kuv ib txwm xaiv 5-6 "cov saib yog vim nws tsim nyog rau kev teeb tsa loj. qis crossover zaus, uas ua rau txo qis hauv kev ua haujlwm ntawm cov neeg soj ntsuam hauv cov ntsiab lus ntawm kev ntsuas.
Qhov no tsis tau txhais hais tias qhov muaj feem ntawm lwm yam khoom siv 5-nti tsis raug txiav tawm. Ntau tus nyiam lub suab ntawm xya lossis yim, thiab kuv tsis xav tsis thoob. Lawv nrov dua, muaj zog dua thiab rov tsim cov ntses bass thaj tsam zoo dua. Txawm li cas los xij, yog tias kuv yuav tsum xaiv, Kuv feem ntau xaiv Tsib vim tias lawv yuav yog tus sawv cev tshaj plaws ntawm tag nrho cov koob thiab muaj feem ntau hais txog lub tswv yim qab lawv. Zoo li qhov no kuv tswj tsis tau yuam kev ...
Cov teeb meem nyiaj txiag
Ob peb xyoos dhau los, thaum nug dab tsi saib mus txog PLN 1500 ib khub Kuv tuaj yeem pom zoo, tib lo lus teb yog luag nyav. Tam sim no, tsis muaj hesitation, kuv hais tias sawv daws. Qhov sib txawv ntawm cov tshuab xws li Adam Audio T5V, JBL 306P MkII, Kali Audio LP6 thiab thaum kawg KRK Rocket 5 G4 lawv yog aesthetic nyob rau hauv cov xwm. Kev yuav ib yam ntawm lawv yuav tsis yuam kev yog tias peb paub tias nws yog dab tsi nyob ze cov saib xyuas npaj rau kev tsim ua haujlwm thiab premixtsis yog rau kev sib xyaw thiab kev txawj ntse.
Nqe: PLN 790 (txhua); Tus tsim tawm: KRK Systems, www.krksys.com Distribution: AudioTech, www.audiotechpro.pl
Hauv ob qhov kawg, koj yuav tsum pib nrog PDU (chav, kev paub, kev txawj), thiab tom qab ntawd cov saib koj tau xaiv yuav tshem tawm ntawm lawv tus kheej. Thiab kuv tau lees tias lawv yuav tsis nyob hauv thaj tsam li PLN 1500. Txawm li cas los xij, rau tsev thiab qhov project kaw studios, nrog rau cov haujlwm uas peb feem ntau ua nyob rau hauv cov chaw zoo li no, cov saib xyuas no yuav yog. Nws yog ntawm lawv uas peb yuav nce peb tus kheej PDU yam.
Hloov pauv
Rokit 5 G4 yog ob txoj kev saib xyuas, ua haujlwm, ua haujlwm hauv hom bi-amp thiab raws li MDF bass-reflex txee - raws nraim li feem ntau ntawm cov khoom ntawm hom no. Yog li cas lawv txawv ntawm lwm tus? Yellow aramid tsav diaphragms? Yog lawm, nws yog KRK daim npav ua lag luam, ib yam li lub logo illuminated. Cov theem inverter khiav raws ntug qis ntawm lub vaj huam sib luag pem hauv ntej thiab muaj cov npoo contoured. Yog, qhov no yog ib qho nthuav heev. Txawm tias qhov nthuav ntau dua yog tias qhov bass-reflex qhov muaj qhov tshwj xeeb tsim - nws yog nkhaus nyob rau hauv cov duab ntawm ib daim ntawv sib npaug L thiab ntev heev, xaus ntawm ib nrab ntawm qhov siab ntawm tus saib.
Hais txog siv high zaus converter tej yam zoo los hais. Qhov no yog ib tug zoo tsim tsav tsheb nrog ib tug loj ferrite hlau nplaum thiab ib tug hluavtaws dome uas dampen resonances zoo. Nws muaj qhov tsis sib haum xeeb tsawg heev thiab kev coj ncaj ncees zoo heev, uas nyob rau hauv ib chav acoustic zoo kom paub meej qhov chaw yooj yim ntawm qhov chaw thiab lawv cov kev ruaj ntseg hauv panorama.
Cov lim dej muaj nyob rau hauv EQ ntu muaj nuj nqi zoo li presets: plaub rau qis zaus thiab plaub rau siab zaus. Nyob rau hauv ob qho tib si, qhov thib peb qhov chaw disables filtering. Rau cov zaus tsawg, qhov sib npaug suav nrog 60 Hz shelving lim thiab 200 Hz band pass lim, thiab rau cov zaus siab, 10 kHz shelving lim thiab 3,5 kHz band pass lim.
Suab zoo heev - pob tshab, tsis muaj suab nrov, raug thiab ua tau zoo dua cov zaus ntau tshaj. Tab sis ... zoo, nws tsis yog superfluous txawm nyob rau hauv cov nqe lus ntawm cov yam ntxwv. Ntau tus neeg tseem ceev faj txog qhov no, ntseeg tias cov lus teb zaus yuav tsum zoo li dej khov.
Tsuas yog cov yam ntxwv qhia peb raws nraim li daim duab hauv tus txiv neej phau ntawv hla tebchaws. Thiab txawm hais tias tus tsav tsheb los ntawm G4 tsis zoo li zoo nkauj ntawm cov duab, kuv ntseeg nws. Nws tsuas ua tau zoo, suab zoo thiab tsis dag. Qhov no yog hom tweeter uas peb nyiam tsis yog rau kev ua tau zoo, tab sis rau cim.
tsim
Rau cov saib ntawm tus nqi no, nws tau ua tsim heev heevua los ntawm ntau yam. Txaus siab rau nws hais tias lub vaj huam sib luag pem hauv ntej nws tus kheej - tag nrho ua los ntawm yas - muaj tsib qhov tshwj xeeb nias nrog kev txhawb nqa thiab kev nthuav dav ntawm lawv cov kev sib raug zoo.
Cov ntaub ntawv nrog cov khoom siv hluav taws xob tsis muaj qhov nthuav. Lub teeb liab analog yog digitized los ntawm Texas Instruments PCM1862 converter thiab tom qab ntawd pub rau Burr-Brown TAS5782 amplifier.
Qhov kawg, raws li kev daws teeb meem digital, yog tswj los ntawm STM32 microcontroller. Thiab nws yog nws tus uas ua haujlwm ntawm kev kho, kuj cuam tshuam nrog lub LCD qhia cov yam ntxwv ntawm qhov kev kho no, thiab tus encoder nrog lub pob rau kev ua haujlwm nrog cov ntawv qhia zaub mov.
Ntawm kev xyaum
Cov neeg saib xyuas lub suab ncaj ncees thiab, tsis zoo li cov tiam dhau los ntawm KRK Rokit (tab sis kuj tseem kim dua qauv), uas feem ntau raug liam tias yog "tus neeg siv khoom", lawv muaj. ntsuas ntsuas. Yog lawm, nws qhov ntau dua tsis yog nkig ntau dua li cov saib xyuas kim dua, tab sis nws tsis tying koj tawm thiab ncua ntev ntawm ib tus neeg mloog.
Cov yam ntxwv tshwm sim ntawm cov saib (ntsuab) thiab cov yam ntxwv ntawm tus kheej lub suab: bass reflex, woofer thiab tweeter. Ib qho kev hnov mob tsis zoo ntawm cov theem inverter ntawm 600 thiab 700 Hz yog tshwm sim nyob rau hauv tag nrho cov yam ntxwv. Cov theem inverter txhawb nqa lub woofer hauv 50-80 Hz ntau. Txoj kab nqes du ntawm kev sib cais ntawm kev sib cais ntawm ntau zaus tswj xyuas qhov kev pom zoo hauv 2-4 kHz ntau yam thaum nws tseem tsis tau muaj txiaj ntsig zoo.
Raws li kuv tau hais hauv cov ntsiab lus tsav tsheb, qhov no yog saib xyuas koj tuaj yeem ntseeg tau. Bass - feem ntau nthuav tawm hauv KRK - ntawm no nws tswj qhov tseeb proportions rau qhov tseeb thiab tseem pom tau meej meej. Tsuav yog peb muaj kev tswj hwm hauv chav acoustics, Rokit 5 G4 yuav tso cai rau peb kom tswj tau txhua yam saum toj no 100 Hz - txawm hais tias lawv kuj muab cov ntaub ntawv ntawm ntau zaus qis dua. Peb hnov 45Hz effortlessly, uas yog ib tug heev ua tau zoo rau xws li compact saib.
Summation
Cov tiam dhau los ntawm KRK Rokit tau pom txawv - qee tus hlub nws, lwm tus tsis nyiam. Lub tswv yim dav dav yog tias lawv muaj zog "DJ" thiab "electronic". Qhov xwm txheej no txawv nrog rau tiam plaub Rokit thiab yeej nrog 5-nti qauv. Koj tuaj yeem pom meej tias ntau txoj haujlwm tau nkag mus rau hauv kev coj lawv tus cwj pwm sonic mus rau qib tom ntej. Rokits loj hlob tsis yog li ntawd.
Ntau xyoo dhau los ntawm kev paub dhau los thiab cov thev naus laus zis thev naus laus zis tau ua rau KRK tsim cov khoom lag luam uas tuaj yeem yooj yim sib tw nrog tus nqi zoo sib xws thiab ua haujlwm zoo li Adam, JBL thiab Kali Audio saib.
Yog tias koj muaj sijhawm, kuj sim XNUMX-nti thiab XNUMX-nti woofer versions rau cov chav loj me me thiab rau kev ua haujlwm uas koj yuav tsum tau ua kom nrov dua thiab muaj cov ntses bass thaj tsam ntau dua.
