PreSonus Eris E4.5 BT - compact saib rau kev mloog

Eris E4.5 BT yog Bluetooth-enabled version ntawm yav dhau los qhia Eris E4.5 compact saib, muab yuav luag tib yam specs ntawm kev ua tau zoo.

Yog tias Vajntxwv Harald, uas tau ua kev cai raus dej Denmark tib lub sijhawm li Mieszko/Mesiko/Dagome (rho tawm raws li qhov tsim nyog) ntawm thaj av tom qab hu ua Poland, tau paub tias nws yuav raug hu ua Blue Tooth, ces peb puas tiam tom qab lub npe menyuam yaus no yuav dhau los ua. lub npe ntawm wireless technology kis tau tus mob ntawm cov ntaub ntawv, nws tej zaum yuav tau poob rau hauv kev xav tob. Feem ntau vim hais tias lub siab xav tau los ntawm nws niaj hnub no los "sib koom" cov neeg Scandinavian tsis tshua muaj kev nkag siab txog niaj hnub no ntawm cov haujlwm no.

Txawm li cas los xij, cia peb tso cov kev xav txog cov teeb meem no rau cov neeg keeb kwm, uas, piav txog cov chaw thiab lub sijhawm, tsim ntau dua li qhov tseeb ntawm lub xeev. Rau peb Bluetooth yuav yog cov txheej txheem uas tau siv nyob rau hauv cov saib PreSound Eris E4.5 BTthiab nyob rau hauv qhov tseeb tsuas yog ib qho ntawm txhua khub, vim hais tias lwm tus yog passive kiag li. Tsis tas li ntawd, Bluetooth tsuas yog ib qho ntxiv rau cov txheej txheem ntawm kev xa cov suab paj nruag, i.e. los ntawm cov qhov (socket) thiab hauv daim ntawv analog.

Ib qho ntawm cov saib hauv lub teeb yog nquag siv thiab xa cov teeb liab hais lus mus rau lwm qhov, uas tseem yog cov qauv tsis muaj zog (tshwj tsis yog hais lus thiab ib qho yooj yim crossover, nws tsis muaj hluav taws xob).

tsim

Tus tsim ntawm cov saib yog tus qauv rau compact multimedia cov khoom siv - ib tug muaj tag nrho cov connectors thiab tag nrho cov electronics, thiab lwm yam muaj tsuas yog ib tug passive saib, uas peb pub lub suab nrov teeb liab los ntawm lub hauv paus. Ob leeg muaj tus qauv x-puab thiab muaj ob sab, txawm tias lawv tsis ua haujlwm hauv hom. Qhov no txhais tau hais tias lub teeb liab yog siv rau ob qho tib si transducers tib lub sijhawm, thiab kev sib cais ntawm cov zaus ntau dua yog ua tiav dhau los ntawm qhov yooj yim crossover. Qhov ntawd yog li cas feem coob ntawm cov khoom siv audiophile yog, yog li tsis muaj dab tsi tsis ncaj ncees lawm. Ntxiv mus, qee zaum yooj yim 6db crossovers tso cai rau koj kom tau txais txiaj ntsig zoo kawg nkaus, tau kawg, raug xaiv rau kev xaiv tsav tsheb zoo.

Qhov ua tau zoo ntawm cov saib ntawm qhov nruab nrab thiab qhov chaw huab cua ntawm cov lim dej qis thiab siab.

Thiab nyob rau hauv cov ntaub ntawv no, nws muaj ib tug nruj woven diaphragm nrog ib txoj kab uas hla ntawm 4,5 "thiab ib tug loj heev deflection rau tej qhov ntev, thiab ib tug 1-nti ib tug nrog ib tug ntaub dome ua tib zoo them nrog ib tug hlau mesh. Nyob rau pem hauv ntej vaj huam sib luag ntawm lub active saib muaj ib tug tswv ntim tswj, lub hwj chim hloov, ib tug sab nraud lub tso suab input thiab lub mloog pob ntseg tso zis, lub xeem ob connectors yog 3,5 hli TRS; lub teeb liab siv rau n yog ntxiv rau lub teeb liab siv rau cov khoom siv ntawm lub vaj huam sib luag tom qab lossis ntawm Bluetooth; nyob rau hauv lem, tom qab ntxig lub ntsaws rau hauv lub qhov (socket), cov neeg hais lus raug muab tua.

Cov kev tswj hwm hauv ntu yog qis (100 Hz) thiab siab (10 kHz) cov ntxaij lim dej ua haujlwm hauv thaj tsam ntawm ± 6 dB, tso cai rau koj kho lub suab rau koj chav lossis cov neeg siv nyiam.

Cov yam ntxwv ntawm tus kheej cov khoom ntawm lub teeb (, thiab twitter) tiv thaiv keeb kwm yav dhau los ntawm cov yam ntxwv ntawm tag nrho. Muaj ib tug muaj zog parasitic resonance, uas yog zoo neutralized nyob rau hauv lub resulting yam ntxwv.

Ua kom muaj kev sib txuas Bluetooth los ntawm kev ua kom cov hom no ntawm cov khoom xa tawm (feem ntau yog lub xov tooj smartphone lossis laptop), nias lub pob ntawm PreSonus saib, thiab lees paub qhov kev xaiv hauv lub tshuab xa tawm. Lub monitor nco txog ob lub teeb liab sib txawv, yog li nws tuaj yeem ua haujlwm sib hloov nrog ob lub transmitters.

Cov txheej txheem nquag ntawm E4.5 BT system yog siv ncaj qha los ntawm lub hauv paus thiab tuaj yeem ua haujlwm nrog qhov hluav taws xob ntawm 100 mus rau 240 V. Lub cev ntawm cov saib yog ua los ntawm MDF, thiab lub vaj huam sib luag pem hauv ntej yog ua los ntawm cov yas tso rau ntawm MDF. lub rooj tsavxwm. Cov khoom siv suav nrog lub hwj chim cable, tus hais lus cable (2m), 3,5mm TRS / TRS cable (1,5m), thiab 3,5mm RCA / TRS cable (1,5m). Kuj tseem muaj cov neeg siv phau ntawv thiab yim lub silicone taw uas tuaj yeem tso rau hauv qab cov neeg hais lus.

Cov yam ntxwv suav nrog kev sib txawv ntawm kev sib haum xeeb. Raws li feem ntau nrog cov suab nrov me me, distortion yog qhov loj tshaj ntawm qhov zaus resonant.

Ntawm kev xyaum

Nrog rau 10 decibel poob hauv kev ua haujlwm, cov saib xyuas cov teeb liab ntawm 75 Hz mus rau ntau dua 20 kHz, thiab lawv ua tau zoo heev. Vim lub qhov ntev ntawm lub qhov, lub suab nrov thiab cuam tshuam yog inevitably nkag rau hauv nws, uas yuav hnov ​​​​hauv 60-100 Hz band thaum ua si lub teeb liab sinusoidal. Yog li ntawd, ua hauj lwm ntawm lub suab ntawm ko taw yuav tsis yog ib qho tseem ceeb cheeb tsam ntawm lub E4.5 BT. Qhov kev ncua deb ntawm lub acoustic chaw ntawm lub transducers yog 10 cm, yog li nyob rau hauv lub ntau yam ntawm 6,8 kHz muaj ib tug ua txhaum ntawm kev ua cov yam ntxwv cuam tshuam nrog rau daim ntawv thov ntawm ib tug wideband teeb liab.

Txawm hais tias pom tseeb qhov tsis zoo hauv kev tsim cov saib, lawv tau pom zoo sib npaug ntawm cov nqi, zoo thiab kev ua haujlwm. Lub xub ntiag ntawm Bluetooth raws tu qauv nyob rau hauv kev xyaum hloov tau yooj yim heev - yog hais tias peb xav mus ua si suab paj nruag los ntawm ib tug portable ntaus ntawv, peb tsis cia siab rau ib tug cable xwb.

Summation

Kev sib tw ua lag luam rau Eris E4.5 BT feem ntau yog Maki CR4 / CR5 BT (thiab tsis ntev los no CR-X versions) thiab JBL 104-BT. Raws li koj tuaj yeem pom, lwm cov tuam txhab lag luam tsis ntse heev thaum nws los tsim cov kev soj ntsuam nrog Bluetooth kev sib txuas - zoo li kev paub tias kev siv cov txheej txheem no muab kev saib xyuas tshwj xeeb "cov neeg siv khoom", ua rau lawv cov kev tshaj lij.

Yog lawm, hloov suab los ntawm AC rau digital, encoding nrog lub encoder uas compresses cov ntaub ntawv, xov tooj cua kis tau tus mob, txiav txim siab, thiab thaum kawg ua rau analog daim ntawv yuav tsis ua rau lub suab zoo dua li tsuas yog kis tau tus kab mob.

Tsis muaj kev sib cav muaj zog uas yuav cuam tshuam qhov zoo ntawm cov xov tooj cua tshaj xov tooj cua digital channel. Tab sis cia peb fim nws, peb tuaj yeem hais dab tsi txog kev saib xyuas compact - thaum qhuas lawv cov ntses bass thaj tsam, crystal ntshiab highs, efficiency thiab pob tshab, lawv tsis muaj peev xwm ua suab nrov yog piv rau purebred studio saib. Thiab qhov no tsis yog lub ntsiab lus, tab sis theej hauv emulating yuav ua li cas peb cov suab paj nruag yuav coj tus cwj pwm zoo li no (thiab feem ntau tsis muaj zog) los ntawm qhov uas nws yuav raug ntaus ntau zaus. Thiab nyob rau hauv cov ntsiab lus no, lub xub ntiag ntawm Bluetooth nyob rau hauv Eris E4.5 BT tsuas yog tsub kom lawv credibility.
