I-Bluesound Powernode neVault: Isethaphu
Nganginakho ukunethezeka kokuba uLenbrook sikaGary Blouse amiswe ngokusetha uhlelo lwami lokuhlola lwe-Bluesound. Ngangizibuza ukuthi kungani kwakudingekile - emva kwalokho, iNosos akakaze ithumele noma ubani ukusetha izinhlelo zabo. Kodwa ukusakaza umsindo we-high-res kunzima kakhulu.
Isibonelo, isitokisi sami, umzila we-WiFi oneminyaka engu-4 ubudala we-AT & T U-WS awuzange uphelele emsebenzini. Isebenza kahle ngama-standard-res audio, ama-MP3s nezinsizakalo zokusakaza, kodwa ngezinye izikhathi ngathola ukudonsa okuncane lapho ngisakaza amafayela angu-24/96 avela ku-HDTracks. I-Blouse ithe noma iyiphi i-router ye-WiFi yesimanje esiphuthumayo kufanele ibe nomkhawulokudonsa okwanele ukusabalalisa okuphezulu kuya kumadivayisi we-Bluesound.
Ngenkathi sinekhono lokuhamba nge-Vault, nami ngifuna ukusakaza kusuka kuthebhulethi ye-Toshiba engigcina umculo wami omkhulu. I-Blouse nami asikwazanga ukwenza lokhu kusebenze, kodwa konke okwakufanele ngiyenze kwakukulanda I-TeamViewer kwi-laptop yami, futhi ne-Lenbrook tech yakwazi ukulungisa i-computer yami ngemizuzu embalwa nje.
Ngakho-ke ngenkathi i-Bluesound ingelula kakhulu ukusetha njenge-Sonos, iningi lama-system lizodayiswa ngabadayisi abaphezulu be-A / V abazokwenza ukusetha nokufakwa kwakho. Ngisho noma uthenga ngokuqondile i-Crutchfield bese uyibeka ngokwakho, kubonakala sengathi ukusekelwa kwe-tech kaLenbrook kukwazi kahle ukuxazulula izinkinga ezingase zivele.
Ngokuthakazelisayo, futhi kahle, uma usebenze okukhiphayo kwe-Powernode esikrinini sokusetha (kuboniswe ngenhla), sishintsha isihlungi esingaphansi kwe-80 Hz sokukhishwa okuncane kanye nesihlungi esiphezulu sama-80 Hz emiphumeleni yesipikha. Ibuye inikeze i-EQ esethiwe elungiselelwe uhlelo lwe-Bluesound Duo sub / sat sat system.

I-Bluesound Powernode ne-Vault: Ukwaziswa Komsebenzisi nokusebenza
Uhlelo lokusebenza lwe-Bluesound lusebenza kancane kancane kusuka kuhlelo lokusebenza lwe-Sonos, kodwa njengoba nje nehlelo lokusebenza lwe-Sonos, kulula ukuvele nje ngokuziqhenya ngokuzungezile. Ngemuva kokuthi ngijwayele uhlelo lokusebenza lwe-Bluesound, ngithole ukuthi kulula ukuyisebenzisa ngezindlela kune-Sonos lokusebenza. Ngithande ukuthi uhlelo lokusebenza lwe-Bluesound lwenze kube lula futhi lushesha ukufinyelela amasevisi wokusakaza. Ngiphinde ngithande indlela esheshayo ngokuphindaphindiwe nangemuva phakathi kwezikrini zayo ezihlukene zokulawula.
Lokhu kuyisimangaliso esincane. Ngisho ne-Samsung ne-LG azihambisani kahle nokusetshenziswa kwe-Sonos. Ukuze inkampani encane ukuyidlula, kodwa kancane kancane, ikhombisa ukuthi into enhle yokwakha kanye nethalenta yokuphatha yaqashwa kulo mzamo.
Ngithole kulula kakhulu ukuqoqa i-Powernode ne-Vault ndawonye, noma ukuyihlanganisa lapho ngifuna. Kulula, ngisho, kunalokho nge-Sonos. Kulula ukulawula ivolumu, kulula ukukhetha umculo oyifunayo, futhi kulula ukushayela ucingo noma ithebulethi nge-Bluetooth. Qala umthombo we-Bluetooth nanoma yikuphi idivayisi ye-Bluesound esakaza ukusakaza futhi idlala i-Bluetooth. Misa umthombo we-Bluetooth, futhi i-Bluesound iqoqa isipele ngento ayidlala ngaphambili.
Ngokuba ukunambitheka kwami siqu, angizange ngibone isidingo esikhulu seVault; Ngivele nginomculo ogcinwe kuma-laptops kanye ne-NAS drive futhi akudingi isitoreji esengeziwe noma i-CD ripper. Kodwa ngiyazi ukuthi abanye abantu basathanda ukuhlelwa kwe-CD, kanti i-Vault iyinto elula ngempela. Vele ushaye i-CD ngaphakathi futhi yenza konke okunye. Ngemuva kwemizuzu eminingana yokuqhaqha kancane (okuyinto i-Blouse ethi isadingeka ukuze uthole ukucaca okucacile kwe-Bluesound efunayo), imidwebo nomculo kuboniswe esikrinini se-iPad.
Idlalwa ngezikhulumi ze-Revel Performa3 F206 ezingabonakali futhi ezingathathi hlangothi, i-Powernode izwakala ihlanzekile kakhulu futhi ibushelelezi. Iphutha kuphela engiliqaphele ukuthi ngezinye izinto ezibonakalayo ezisezingeni eliphansi, ngagcina ngifake ivolumu kuya max, noma eduze nayo. Ngemva kokuqeda ukubuyekezwa futhi ngithumele imikhiqizo emuva, i-Lenbrook rep yangichazela ukuthi kunomthamo omkhulu wevolumu ngaphakathi kwemenyu yokusetha engangonyuka ngo-+10 dB ngezimo lapho izinga levolumu linganele.

I-Bluesound Powernode: Izinyathelo
Ngasebenzisa i-Analyzer yami ye-Clio 10 FW, i-Audio Precision Dual Domain System I-Analyzer eyodwa ne-LinearX LF280 isihlungi (okudingekayo ku-Class D amps) ukuqhuba ukuhlolwa okuhlukahlukene ku-Powernode. Inqubo yami yokuhlola i-amplifier evamile yayihlukile kancane ngoba angikwazi ukufaka izibonakaliso zokuhlola ngqo ku-Powernode (akukho ukufaka komugqa). Kodwa ngakwazi ukubhala ezinye izibonakaliso zokuhlola, zilayishe ku-laptop yami, bese uzidlala ngokusebenzisa uhlelo lokulinganisa.

Okukhipha amandla, ama-oh ohms (1 kHz )
Iziteshi ezimbili eziqhutshwayo: 12.1 watts ngesiteshi se-RMS ku-0.16% i-THD + N (ivolumu eningi nesignali ye-0 dBFS) ( * bheka inothi ngezansi)
Isiteshi esine-1: i-31.3 watts i-RMS ku-0.03% i-THD + N
Okukhipha amandla, ama-oh ohms (1 kHz)
Iziteshi ezimbili eziqhutshwayo: 24.0 watts ngesiteshi se-RMS ku-0.16% i-THD + N (ivolumu eningi nesignali esingu-0 dBFS)
Isiteshi esiphezulu 1: 47.4 ama-Watts RMS ku-0.05% THD + N
Yimpendulo yevamenti oyibonayo eshadini, okukhiphayo kwe-subwoofer kusebenze (ukulandelana okuluhlaza) futhi kuvinjelwe (umkhondo omude). Zonke lezi zilinganiso ngaphandle kokubili zibukeka zihle futhi zivale ngokwanele kuma-specs ambalwa e-Bluesound anikeziwe.
Impendulo yephindaphindiwe ayizange imangalisise, ngenxa yokuthambekela okuncane okwenyukayo. Kuphela ngamakhomitha amathathu we-decibel ku-20 kHz-into engabantu abaningi abakwazi ukuyizwa noma ngeke bayibone. Kodwa nokho, akuyona into engivame ukuyibona ku-amp-quality amp state state amp.
Ngangimangalisa kakhulu ukubona umehluko omkhulu emkhatsini wamandla okushiwo yizo zombili iziteshi eziqhutshwa ngokumelene nomzila owodwa oqhutshwa. Njengoba iziteshi zombili ziqhutshwa, i-limiter yangaphakathi igoqa phansi ngokuvuthayo ngevolumu enkulu, inciphisa ukuphazamiseka cishe ku-0.16% ngokuvota okugcwele futhi iwele kancane emandleni alinganisiwe. * Ngokusho kukaLenbrook, lokhu kungumphumela wokuzikhandla we-Bluesound 'Soft Clipping technology,' njengoba ngiyiqonda njengemikhawulo esinqunyiwe evimbela ukukhulisa nezikhulumi ukuba zingonakaliswa lapho kugcwele ukuqhuma. I-NAD isetshenzisiwe ubuchwepheshe obufanayo noma obufanayo kuma-amplifiers awo amashumi eminyaka
Kodwa-ke, ngesiteshi esisodwa nje esiqhutshwayo, imingcele (engiyiqagelayo ilawulwa ukufunwa okuphelele kumandla kagesi esikhundleni sokuphuma kwe-amps) ayikho esithombeni futhi i-amp isaphezu kwamandla alinganisiwe kalula. Qaphela ukuthi angikwazi ukusebenzisa umthamo wami ojwayelekile we-1% we-THD + N ngoba ngangingakwazi ukwenza amandla ngokumelene ne-THD + N ngokushisa usebenzisa amathoni wokuhlola angaphandle, nangenxa yezinyathelo ezinkulu kakhulu ekulawulweni kwevolumu ye-Powernode - - ngokuthinta okulodwa kwesilawuli sevolumu esiphezulu, ukuphazamisa ama-8 ohms kuya ngqo kusuka ku-0.03% ukuya ku-3.4%.
Ngakho-ke yiyiphi i-upshot lapha? Njengoba i-limiter iphoqa phansi kanzima njengoba okukhiphayo kuhambisana nemikhawulo yokunikezwa kwamandla, uma udlala izinto eziningi ezicindezelekile ngokuqukethwe okuqinile kwe-mono - njengengoma yami yokuhlola ye-fave, "Kickstart My Heart" - ungase ungatholi ngokwanele ivolumu. Ngesipikha sesiphakamiso esilinganisiwe (ngokunembile, sizocabangela) ku-88 dB SPL ku-1 watt / 1 imitha, okusho ukuthi i-Powernode izophuma cishe cishe ku-99 dB ngencwadi yohlelo oluthile engikhuluma ngalo.
