Ezi zibonakala zifanelekileyo ifom yeemveliso ezifana nalezi. Akukho zininzi zonxibelelwano ezinikezelwayo, kodwa andizange ndifune ukuba nayiphi na into, nokuba. Kulungile, mhlawumbi i-headphone jack kwi-Powernode iya kuba yinto enhle.
Ngeenkonzo ezintathu zokusasaza ngoku zinikezelwa (kwaye i-WiMP, i-Highresaudio kunye neQobuz ivakalise kodwa ingekafumaneki kwinkqubo yam yokuvavanya), amandla okuhanjiswa kweBluesound ayifuni kwiinkonzo ezingama-31 ze-Sonos ezikhoyo ngoku. Uninzi lweenkonzo zikaSonos zincomekile, nangona kunjalo. Ukongeza kwangoko kweSpotify Connect kwiBluesound kukunceda kakhulu; ngoku konke kuyifunayo yiPandora.

I-Bluesound Powernode neVault: Ukusetha
Ndineenzuzo zokuba uLenbrook weGary Blouse ayeke ukuseka inkqubo yam yokuhlola iBluesound. Ndazibuza ukuba kutheni kuyimfuneko - emva koko, uSonos akazange athumele nabani na ukusekela iinkqubo zabo. Kodwa ukuhanjiswa kwe-audio-res audio kunzima kakhulu.
Ngokomzekelo, isitokisi sam, i-ATF ye-AT & T kwivesi ye-WiFi router yayingeyona nto ifikelele kumsebenzi. Yasebenza kakuhle nge-audio-res audio, ii-MP3s kunye neenkonzo zokusakaza, kodwa ngamanye amaxesha ndifumene i-dropouts ezimbalwa xa ndisasaza iiFayile ezingama-24/96 kwi-HDTracks. I-Blouse yathi nayiphi na i-router ye-WiFi ephakamileyo ephakamileyo ye-high quality ifanele ibe ne-bandwidth eyaneleyo yokusasaza kwi-high-res ukuya kumadivayisi e-Bluesound.
Ngethuba sasiba ne-Vault ephathekayo, ndandifuna ukuhlawulela kwi-laptop yeToshiba apho ndigcina amaninzi omculo wam. I-Blouse kunye nathi asikwazanga ukwenza le nto, kodwa konke okufuneka ndiyenze kwakukhuphela i-TeamViewer kwi-laptop yami, kunye ne-Lenbrook tech yakwazi ukwenza icomputer yam ilungele impela imizuzu emibini.
Nangona i-Bluesound ayinakulula ukuyibeka njengo-Sonos, ezininzi iinkqubo ziya kuthengiswa ngabadayisi abaphezulu be-A / V abaza kuyenza ukusetha nokufakela. Nangona uthengula ngqo kwi-Crutchfield uze uyibeke ngokwakho, kubonakala ngathi inkxaso ye-tech kaLenbrook inokukwazi ukusombulula naziphi na iingxaki ezinokuvela.
Kuyathakazelisa, kwaye ngokufanelekileyo, xa usebenze umbane we-Powernode kwisikrini sokuseta (siboniswe ngasentla), sitshintsha kwisihlungi esingaphansi kwe-80 Hz kwisiqulatho esingaphantsi kunye nefayili ephezulu ye-80 Hz kwiziphumo zesithethi. Ikwabonelela kwakhona nge-EQ ekhethiweyo eyenzelwe i-Bluesound Duo / yesitethi inkqubo.

I-Bluesound Powernode neVault: I-Experience User kunye neNtsebenzo
I-app ye-Bluesound isebenza ngokungafaniyo kwi-app ye-Sonos, kodwa njengokuba kusebenza ne-Sonos, kulula ukuyifumana ngokukhawuleza. Emva kokuba ndiyifake kwi-app ye-Bluesound, ndandiyifumene kulula ukuyisebenzisa ngeendlela ezingenanto ye-Sonos. Ndandiyithanda ukuba insiza yeBluesound yenza kube lula kwaye kukhawuleza ukufikelela kwiinkonzo zokuhambisa. Ndandiyithanda nendlela yokukhawuleza ngokukhawuleza phakathi kwesikrini sazo ezahlukeneyo.
Lo mnye ummangaliso omncinci. Nangona i-Samsung kunye ne-LG azihambelani ngokukhululeka kokusetyenziswa kweNyana. Ukuba inkampani encinci ukuyiqhawula, nangona kunjalo, iphakamisa ukuba into ebalulekileyo yoyilo kunye neetalente zokuphatha yaqashwa kulo mzamo.
Ndakufumana kulula kakhulu ukuqoqa i-Powernode kunye neVault kunye, okanye ukuyihlanganisa xa ndifuna. Kulula, kunoko, kunokuba neNonos. Kulula ukulawula umthamo, kulula ukukhetha umculo owufunayo, kwaye kulula ukudibanisa ifowuni okanye ithebhulethi ngeBluetooth. Qala umthombo weBluetooth kwaye nayiphi na ifowuni yeBluesound isasaza kwaye idlala iBluetooth. Yeka umthombo weBluetooth, kunye neBluesound ikhupha phezulu ngezinto ezidlala ngaphambili.
Ngenxa yam enomdla, andizange ndibone isidingo esikhulu seVault; Ndivele ndibe nomculo ogcinwe kwii-laptops kunye ne-NAS drive kwaye akukho mfuneko yokugcina okanye i-CD. Kodwa ndiyazi ukuba abanye abantu bathanda ukulungeleka kweCD, kwaye iVault iyakulungeleka. Sula nje iCD ngaphakathi kwaye yenza konke. Emva kwemizuzu emininzi yokukhawuleza ngokukhawuleza (okwakuthi i-Blouse yayimfuneko ukufumana ingcamango ecacileyo yeBluesound yayifuna), umzobo nomculo uboniswe kwisikrini se-iPad.
Eyadlala ngokubhenela kwam i-Revel Performa3 F206, i-Powernode yayisicacile kakhulu kwaye ilula. Iphutha elilodwa lam ndiyibonile kukuba ngezinye izinto eziphathekayo kwinqanaba eliphantsi, ndagqiba ukuba ndibe ne-crank ivolumu kwi-max, okanye kufuphi nayo. Emva kokuba ndigqibe ukuhlaziywa kwaye ndathumela iimveliso kwakhona, i-Lenbrook rep yangichazela ukuba kukho ukuphakama kwevolumu kwimenyu yokuseta enganyuswa ngu -10 dB kwiimeko apho izinga levolumu lingenalo.

I-Bluesound Powernode: Imilinganiselo
Ndasebenzisa umhlalutyi womsindo we-Clio 10 FW, i-Audio Precision Dual Domain System I-analyzer eyodwa kunye ne-LinearX yeLF280 kwisihlungi (esifunelwe kwii-Class D amps) ukuqhuba iimvavanyo ezahlukeneyo kwi-Powernode. Inkqubo yam yokuhlola yokuvusa i-amplifier eqhelekileyo yayininzi ngenxa yokuba andinako ukufaka iimpawu zokuvavanya ngqo kwi-Powernode (akukho mvelaphi yomgca). Kodwa ndakwazi ukubhala iimpawu ezithile zokuvavanya, zilayishe kwi-laptop yami, uze uzidlale kwinkqubo yesilinganiselo.
Ukuphendula ngokuphindaphindiweyo
-0.09 / + 0.78 db, 20 Hz ukuya kuma-20 kHz
Isilinganiselo sesandi somsindo (1 watt / 1 kHz)

Isiphumo samandla, ii-oh ohms (1 kHz )
Iikhomputha ezimbini eziqhutywayo: 12.1 iitts nganye nge-RMS yesiteshi kwi-0.16% ye-THD + N (umthamo ophezulu nge-signal dBFS ye-0) ( * bona inqaku elingezansi)
I-channel eqhutywayo: 31.3 i-watts i-RMS kwi-0.03% ye-THD + N
Ukuphuma kwamandla, ii-oh ohms (1 kHz)
Iikhomputha ezi-2 eziqhutywa: ii-24.0 ii-watts nganye nge-RMS kwi-0.16% ye-THD + N (umthamo ophezulu kunye nesignali esingu-0 dBFS)
I-channel eqhutywayo: 47.4 ii-watts i-RMS kwi-0.05% ye-THD + N
Yimpendulo yevamava oyabona kwitshathi, kunye ne-subwoofer eyenziwa ngokusebenzayo (ulandelelwano oluluhlaza) kwaye lucacisiwe (umtsalane obomvu). Yonke le milinganiselo ngaphandle kokuba ezimbini zibukeka zihle kwaye zivale ngokwaneleyo kwii-specs ezimbalwa.
Ukuphendula ngokuphindaphindiweyo akuzange kumchukumise, ngenxa yokunyuka kwamandla okuhamba. Kuphela malunga neekota ezintathu ze-decibel kwi-20 kHz-into eninzi abantu abanakuyayiva okanye abayiyi kubona. Kodwa kunjalo, akuyinto endiyibonayo kwi-high-state amp-state amp.
Ndandimangaliswe gqitha ukubona umda omkhulu kwimveliso yamandla kunye neendlela zombini eziqhutyelwayo ngokubhekiselele kwisitya esinye. Ngezo zombini iziteshi eziqhutywayo, i-limiter yangaphakathi igxobhoza ngokugqithiseleyo kumthamo omkhulu, ukunciphisa ukuphazamiseka ukuya kwi-0.16% ngokuvakala ngokupheleleyo kwaye iwele ngamandla kumlinganiselo olinganisiweyo. * Ngokutsho kukaLenbrook, esi sizathu sokwemvakalelo sobuchwepheshe be-Bluesound 'Soft Clipping teknoloji', njengoko ndiyayiqonda ukuba ngumlinganiselo wokunciphisa okukhusela ukuba izikhulu kunye nezithethi zingabonakaliswa xa i-cranked full-explosion. I-NAD isebenzise iteknoloji efanayo okanye efana nayo kwiimpawu zayo ezimashumi eminyaka
Nangona kunjalo, ngekontra enye kuphela, i-limiter (endiyicinga ukuba ilawulwa yintlawulo yamandla kwisibonelelo samandla kunokuba imveliso ye-amps) ingaphumi komfanekiso kwaye i-amp amp ihamba ngamandla ngaphezu kwamanani. Qaphela ukuba andinakusebenzisa i-1% ye-THD + N ye-threshold ngenxa yokungazange ndikwazi ukwenza amandla ngokubhekiselele kwi-THD + N ngokusebenzisa iitoni zokuhlola zangaphandle, kwaye ngenxa yamanqanaba amancinane ekulawuleni kweVolnode - - ngomgca omnye wokulawula umthamo ophezulu, ukuphazamiseka kuma-oh ohms kuye ngqo ukusuka ku-0.03% ukuya kwi-3.4%.
Ngoko ke yintoni i-upshot apha? Ngommitha wokukhawulela ngokukhawuleza njengoko umkhiqizo ufikelela kumda wokunikezelwa kwamandla, ukuba udlala izinto ezininzi ezincinci ezixininisekile kunye nomxholo onamandla we-mono - njenge-tame ye-fave yesigxina, "I-Kickstart My Heart" - unokufumana ivolumu. Ngebini lezivakalisi ezilinganisiweyo (ngokuchanekileyo, siya kuthatha) kwi-88 dB SPL kwi-1 watt / 1 imitha, oko kuthetha ukuba i-Powernode iya kuphuma kuma-99 dB kunye neprogram yolu hlobo endithetha ngalo.

I-Bluesound Powernode neVault: I-Final Take
Ngokusekelwe kwinto endiyibonayo xa ezinye iinkampani ezininzi zizama isandla saso kumculo wokudlala, ndingazange ndilindelwe kakhulu kwiBluesound - Ndandicinga kakhulu ukuba ngaba ngumdlali ophezulu we-sound audio kunye ne-clumsy interface ehlanganisiweyo . Kodwa ndivuyiswa kukuba, ndiphosakele. I-interface-class-class, kunye nendlela elula kakhulu endingayifumanayo ukuzonwabisa nomculo ophezulu.
I-Powernode iyinto enhle ukuba ufuna ukulungelelaniswa kwe-amp amp, kodwa kubonakala ngathi kumgangatho apho umgangatho ophezulu omsindo unomgomo, mhlawumbi ndifuna ukuthoba i-ass. Ngoko kum, i-$ 449 yeNode iyindawo ekhangayo yeBluesound-indlela efikelelekayo kunye neyona ndlela elula ukuyongeza ukusasazwa kweefayili eziphezulu ezigcinwe, kunye neenkonzo zokusasaza nge-intanethi, kunye nekhono lamanqanaba amaninzi, kwiinkqubo zomsindo ophezulu.
