PreSonus Eris E4.5 BT - compact monitors yekuteerera

The Eris E4.5 BT iBluetooth-enabled vhezheni yekare yakaunzwa Eris E4.5 compact monitors, ichipa dzinenge dzakafanana specs maererano nekuita.

Kudai Mambo Harald, uyo akabhabhatidza Denmark panenge panguva imwe cheteyo naMieszko/Mesiko/Dagome (bvisa sezvakakodzera) wenyika yakazonzi Poland, akanga aziva kuti aizonzi Blue Tooth, ipapo mazana matatu ezvizvarwa gare gare zita remadunhurirwa iri raizova. zita rewireless tekinoroji kutapurirana data, angangodaro akawira mukufunga kwakadzama. Kunyanya nekuti chishuvo chaakapihwa nhasi che "kubatanidza" vanhu veScandinavian vaive nechekuita nekunzwisisa kwemazuva ano kwechiitiko chakadaro.

Zvisineyi, ngatisiyei kufunga nezvenyaya idzi kune vanyori venhoroondo, avo, vachitsanangura nzvimbo idzodzo nenguva, vanogadzira zvinopfuura chokwadi chenyika. Zvedu Makaralı ichave iyo protocol yakashandiswa mumamonitor PreSound Eris E4.5 BTuye kutaura zvazviri imwe chete yepeya imwe neimwe, nekuti imwe yacho haina zvachose. Mukuwedzera, Bluetooth inongova yekuwedzera kune yakajairwa nzira yekuendesa masaini masaini, i.e. kuburikidza nezvigadziko uye mune analogi fomu.

Imwe yevatariri museti inoshanda uye inotumira chiratidzo chemukurukuri kune imwe, iyo inoramba iine chimiro (kunze kwevatauri uye nyore crossover, haina magetsi).

design

Dhizaini yemamonitor ndeye yakajairwa compact multimedia kits - imwe ine zvese zvinongedzo uye zvese zvemagetsi, uye imwe ine chete passive monitor, yatinodyisa chiratidzo chegudzanzwi kubva pachigadziko. Ose ane chimiro chakaita x uye ane mativi maviri, kunyangwe asingashande mumodhi. Izvi zvinoreva kuti chiratidzo chinoshandiswa kune vese vashanduri panguva imwe chete, uye kupatsanurwa kwepamusoro mafambiro kunoitwa passively kuburikidza necrossover iri nyore. Ndiwo maitiro mazhinji eanonzi audiophile kits ari, saka hapana chakaipa nazvo. Uyezve, dzimwe nguva dzakareruka 6db crossovers dzinokutendera kuti uwane inonakidza yekupedzisira mhedzisiro, hongu, zvichienderana nekusarudzika kwakaringana kwevatyairi.

Izvo zvinoguma zvaitika zvemamonitor pane zvepakati uye zvakanyanyisa zvigadziriso zvepasi uye zvakakwirira masherufu mafirita.

Uye mune iyi kesi, ine yakaomeswa yakarukwa diaphragm ine dhayamita ye4,5 ″ uye yakakura kwazvo kutsauka kwezviyero zvakadaro, uye 1-inch imwe ine jira dome rakafukidzwa nesimbi mesh. Pamberi pepaneru yeinoshanda monitor pane master volume control, switch yemagetsi, yekunze stereo yekuisa uye yekubuda kwehedhifoni, maviri ekupedzisira ekubatanidza ari 3,5 mm TRS; chiratidzo chinoshandiswa kune n chinowedzerwa kune chikwangwani chakaiswa kune izvo zvinopinda pane yekumashure kana kuburikidza neBluetooth; zvakare, mushure mekuisa plug musocket, vatauri vanodzimwa.

Izvo zvinodzora muchikamu zvakaderera (100 Hz) uye akakwira (10 kHz) masherufu mafirita anoshanda muhupamhi hwe ± 6 dB, achikubvumidza kuti ugadzirise ruzha kukamuri yako kana zvido zvemushandisi.

Hunhu hwezvikamu zvega zvega seti (, uye tweeter) pakatarisana nekumashure kwezvinokonzeresa hunhu hwese. Iko kune yakasimba parasitic resonance, iyo inobudirira neutralized mune inoguma hunhu.

Kumisikidza kubatana kweBluetooth kunodzika kumisa iyi modhi pamudziyo wekutumira (kazhinji smartphone kana laptop), kudzvanya bhatani pane PreSonus monitor, uye kusimbisa kusarudzwa mune transmitter. Iyo yekutarisa inorangarira maviri akasiyana masaini masosi, saka inogona kushanda ichichinjana nema transmitter maviri.

Iyo inoshanda seti yeE4.5 BT system inoshandiswa zvakananga kubva kumagetsi uye inogona kushanda nemagetsi kubva ku100 kusvika ku240 V. Muviri wevatariri unogadzirwa neMDF, uye jira repamberi rinogadzirwa nepurasitiki yakaiswa pa MDF. board. Iyo kit inosanganisira tambo yemagetsi, tambo yekutaurisa (2m), 3,5mm TRS/TRS tambo (1,5m), uye 3,5mm RCA/TRS tambo (1,5m). Kune zvakare bhuku remushandisi uye masere silicone tsoka anogona kuiswa pasi pevatauri.

Hunhu hunosanganisira harmonic distortion. Sezvinowanzoitika kune magudzanzwi madiki, kukanganisa kwakakura pane resonant frequency.

Pakuita

Nekudonha kwegumi decibel mukubudirira, mamonitor anobata masaini kubva pa10 Hz kusvika pamusoro pe75 kHz, uye vanozviita nehungwaru. Nekuda kwehukuru hwemugero, ruzha uye kupindira zvinopinzwa mukati maro, izvo zvinonzwika mubhendi re20-60 Hz kana uchiridza sinusoidal chiratidzo. Naizvozvo, kushanda neruzha rwetsoka hakuzove nzvimbo yakakosha yebhazi yeE100 BT. Nharaunda pakati peacoustic centers yevashanduri ndeye 4.5 cm, saka muhuwandu hwe 10 kHz pane kukanganisa kwemaitiro ekugadzirisa ane chokuita nekushandiswa kwechiratidzo che wideband.

Pasinei nezvikanganiso zviri pachena mukugadzirwa kwevatariri, ivo vakanyatsogadzikana maererano nemutengo, unhu uye kushanda. Kuvapo kweiyo Bluetooth protocol mukudzidzira kunobva kwaita nyore - kana tichida kuridza mimhanzi kubva kune inotakurika mudziyo, isu hativimbe netambo chete.

Summation

Musika kukwikwidza Eris E4.5 BT inonyanya Maki CR4 / CR5 BT (uye ichangoburwa CR-X shanduro) uye JBL 104-BT. Sezvauri kuona, vamwe vagadziri havana kunyanya kungwara kana zvasvika pakugadzira mamonitor ane Bluetooth kubatana - sekunge anonzwa kuti kuitwa kweiyi protocol kunopa monitors yakanangana ne "consumerism", kukanganisa hunyanzvi hwavo.

Ehe, kushandura odhiyo kubva kuAC kuenda kudhijitari, encoder ine encoder inomanikidza data, kufambisa nhepfenyuro, decoding, uye pakupedzisira kugadzirisa kune analogi fomu hazvizoite kuti ruzha urwu rwuve nani pane kungofambiswa netambo.

Iko hakuna nharo dzakasimba dzinogona kupokana iyo yemhando mukana wetambo pamusoro pedhijitari redhiyo chiteshi. Asi ngatitarisei, chii chatingataure nezve compact monitors - tichirumbidza mabass avo, makristasi akajeka marefu, kushanda nesimba uye pachena, ivo havakwanise kuridza kurira kana vachienzaniswa neakachena studio monitors. Uye iyi haisi iyo pfungwa, asi pane kutevedzera maitiro emimhanzi yedu pamaseti akadaro (uye kazhinji asina kusimba) kubva kwaanozoridzwa kakawanda. Uye mumamiriro ezvinhu aya, kuvapo kweBluetooth muEris E4.5 BT kunongowedzera kuvimbika kwavo.
