PreSonus Eris E4.5 BT - oyang'anira yaying'ono kuti amvetsere

Eris E4.5 BT ndi mtundu wothandizidwa ndi Bluetooth wa makina owunikira a Eris E4.5 omwe adayambitsidwa kale, omwe amapereka pafupifupi mawonekedwe ofanana potengera magwiridwe antchito.

Ngati Mfumu Harald, amene anabatiza Denmark pafupifupi nthaŵi imodzi ndi Mieszko/Mesiko/Dagome (chotsani monga kuyenerera) wa dziko lomwe pambuyo pake linatchedwa Poland, akanadziŵa kuti adzatchedwa Blue Tooth, ndiye kuti mibadwo mazana atatu pambuyo pake dzina lotchulirikali likanakhala. dzina la ukadaulo wopanda zingwe kufala kwa data, mwina akanagwa m'malingaliro ozama. Makamaka chifukwa chikhumbo chomwe chimaperekedwa kwa iye lero kuti "agwirizane" anthu a ku Scandinavia analibe chochita ndi kumvetsetsa kwamakono kwa ntchito yotereyi.

Komabe, tiyeni tisiye kulingalira pa nkhanizi kwa akatswiri a mbiri yakale, omwe, pofotokoza malo ndi nthawi zimenezo, amapanga zambiri kuposa zenizeni zenizeni. Kwa ife bulutufi idzakhala protocol yomwe idagwiritsidwa ntchito pazowunikira PreSound Eris E4.5 BTndipo kwenikweni imodzi yokha ya gulu lirilonse, chifukwa ina imakhala yongochita chabe. Kuphatikiza apo, Bluetooth ndiyongowonjezera ku njira yokhazikika yoperekera ma audio, i.e. kudzera muzitsulo ndi mawonekedwe a analogi.

Mmodzi wa oyang'anira mu seti akugwira ntchito ndipo amatumiza chizindikiro cha wokamba nkhani kwa winayo, chomwe chimakhalabe chokhazikika (kupatulapo oyankhula ndi crossover yosavuta, alibe magetsi).

kupanga

Mapangidwe a oyang'anira ndi muyezo wa zida zophatikizira zamawu - imodzi imakhala ndi zolumikizira zonse ndi zamagetsi zonse, ndipo ina ili ndi chowunikira chokha, chomwe timadyetsa chizindikiro chokweza mawu kuchokera pansi. Onse ali ndi mawonekedwe a x ndipo ali ndi mbali ziwiri, ngakhale kuti sagwira ntchito. Izi zikutanthawuza kuti chizindikirocho chimagwiritsidwa ntchito kwa ma transducers onse panthawi imodzi, ndipo kupatukana kwa maulendo apamwamba kumachitidwa mosasamala kupyolera mu crossover yosavuta. Umu ndi momwe ambiri otchedwa audiophile kits alili, kotero palibe cholakwika ndi zimenezo. Komanso, nthawi zina ma crossovers osavuta a 6db amakupatsani mwayi wopeza zotsatira zomaliza zosangalatsa, zachidziwikire, kutengera kusankha koyenera kwa madalaivala.

Zotsatira zake zowunikira pazikhazikiko zapakatikati komanso monyanyira za zosefera zotsika komanso zapamwamba.

Ndipo pamenepa, ili ndi diaphragm yolukidwa yolimba yokhala ndi mainchesi 4,5 ″ komanso kupatuka kwakukulu pamiyeso yotere, ndi inchi imodzi yokhala ndi dome lansalu lomwe limakutidwa mosamala ndi mauna achitsulo. Patsogolo la polojekiti yogwira ntchito pali kuwongolera kwa voliyumu, chosinthira mphamvu, cholumikizira chakunja cha stereo ndi chotulutsa chamutu, zolumikizira ziwiri zomaliza ndi 1 mm TRS; chizindikiro chomwe chimagwiritsidwa ntchito ku n chikuwonjezeredwa ku chizindikiro chomwe chimagwiritsidwa ntchito pazolowera kumbuyo kapena kudzera pa Bluetooth; nawonso, mutalowetsa pulagi mu socket, oyankhula amazimitsidwa.

Zowongolera zomwe zili m'gawoli ndizochepa (100 Hz) komanso zosefera zamashelufu zazitali (10 kHz) zomwe zimagwira ntchito mumitundu yosiyanasiyana ya ± 6 dB, zomwe zimakulolani kuti musinthe mawu kuchipinda kapena zomwe amakonda.

Makhalidwe a magawo amtundu wa seti (, ndi twitter) motsutsana ndi maziko a zotsatira zake zonse. Pali amphamvu parasitic resonance, amene bwino neutralized mu chifukwa khalidwe.

Kuyatsa kulumikizidwa kwa Bluetooth kumatsikira ndikuyambitsa njirayi pazida zotumizira (nthawi zambiri foni yamakono kapena laputopu), kukanikiza batani loyang'anira PreSonus, ndikutsimikizira zomwe zasankhidwa. Woyang'anira amakumbukira magwero awiri osiyana siyana, kotero amatha kugwira ntchito mosinthana ndi ma transmitters awiri.

Pulogalamu yogwira ntchito ya E4.5 BT imayendetsedwa molunjika kuchokera ku mains ndipo imatha kugwira ntchito ndi magetsi kuchokera ku 100 mpaka 240 V. Thupi la oyang'anira limapangidwa ndi MDF, ndipo gulu lakutsogolo limapangidwa ndi pulasitiki yoyikidwa pa MDF. bolodi. Zidazi zimaphatikizapo chingwe chamagetsi, chingwe cholumikizira (2m), chingwe cha 3,5mm TRS/TRS (1,5m), ndi chingwe cha 3,5mm RCA/TRS (1,5m). Palinso buku la ogwiritsa ntchito ndi mapazi asanu ndi atatu a silicone omwe amatha kuyikidwa pansi pa okamba.

Makhalidwe kuphatikizapo kusokonezeka kwa harmonic. Monga momwe zimakhalira ndi zokuzira mawu zing'onozing'ono, kupotoza kumakhala kwakukulu kwambiri pazifukwa zomveka.

Pochita

Ndi kutsika kwa 10 decibel mu mphamvu, oyang'anira amanyamula ma siginecha kuchokera pa 75 Hz mpaka kupitirira 20 kHz, ndipo amachita izi mosamala kwambiri. Chifukwa cha kukula kwa ngalandeyo, phokoso ndi zosokoneza zimalowetsedwamo, zomwe zimamveka mu gulu la 60-100 Hz posewera sinusoidal. Choncho, kugwira ntchito pa phokoso la phazi sikudzakhala malo ofunikira a basi kwa E4.5 BT. Mtunda pakati pa malo omvera a transducers ndi 10 cm, kotero mu 6,8 kHz osiyanasiyana pali kuphwanya machitidwe opangira omwe amagwirizanitsidwa ndi kugwiritsa ntchito chizindikiro cha wideband.

Ngakhale zolakwika zodziwikiratu pamapangidwe a oyang'anira, amakhala olinganizika bwino pamtengo, mtundu ndi magwiridwe antchito. Kukhalapo kwa protocol ya Bluetooth poyeserera kumakhala kothandiza kwambiri - ngati tikufuna kuimba nyimbo kuchokera ku chipangizo chonyamula, sitidalira chingwe chokha.

Chidule

Mpikisano wamsika wa Eris E4.5 BT ndiwo makamaka Maki CR4/CR5 BT (ndi mitundu yaposachedwa ya CR-X) ndi Chithunzi cha JBL 104-BT. Monga mukuwonera, opanga ena sakhala anzeru kwambiri pankhani yopanga oyang'anira ndi kulumikizana kwa Bluetooth - ngati kuti akuwona kuti kukhazikitsidwa kwa protocol iyi kumapatsa oyang'anira "kugula" kwapadera, kusokoneza ukadaulo wawo.

Inde, kutembenuza mawu kuchokera ku AC kupita ku digito, kusindikiza ndi encoder yomwe imakanikiza deta, kutumiza pawailesi, kusindikiza, ndipo pamapeto pake kusinthidwa kukhala mawonekedwe a analogi sikungapangitse kuti izi zimveke bwino kusiyana ndi kufalikira pa chingwe.

Palibe mikangano yamphamvu yomwe ingatsutsane ndi ubwino wa chingwe pa njira ya wailesi ya digito. Koma tiyeni tiyang'ane nazo, tinganene chiyani za ma compact monitors - kwinaku akuyamika mabass awo, ma crystal owoneka bwino, owoneka bwino komanso owonekera, sangathe kumveka bwino poyerekeza ndi oyang'anira ma studio. Ndipo iyi si mfundo yake, koma m'malo motengera momwe nyimbo zathu zimakhalira pamaseti otere (ndipo nthawi zambiri ofooka) omwe aziyimbidwa nthawi zambiri. Ndipo munkhaniyi, kukhalapo kwa Bluetooth mu Eris E4.5 BT kumangowonjezera kukhulupirika kwawo.
