Abakwa-Grace Digital Bluetooth Abathengi be-Stereo: Ikhwalithi Yomsindo
Ngokuvamile isibonakaliso esihle kakhulu lapho igama lokuqala lamanothi ami okulalela "Wow!" Noma mhlawumbe ngifinyelele futhi ukusetshenziselwa ukujwayela izinhlelo zomsindo ezingenazintambo zonke-in-one.
Ngomshini we-guitarist u-Emily Remler ka-"Daahoud" ovela e- East Meets Wes , ukuthembeka kwegitala likaRemler namadubhu kwakungcono kakhulu, kunomsindo ongaphelele futhi ovulekile kunalokho engikujwayele ukuzwa kusuka ku-$ 200 we-gear audio. Ngangithanda umsindo ogcwele ongakapheli wegitala, ikakhulukazi; eziningi izinhlelo zokulalelwayo ezishibhile zihlanekezela kahle uma zidla ama-guitarists amaningi kakhulu, azungezile. Ngangithanda nokuthi amadubhu asakaza egumbini phambi kwami, esikhundleni sokuboshwa ebhokisini elilodwa elincane njengezinhlelo eziningi ze-Bluetooth.
"I-Daahoud" yayingeyona impela njengokungathi ngiyithandile ngoba uhlelo aluzange lunikeze i-ton of bass. Yizo izikhulumi ezimi ngamasentimitha angu-6 ukusuka odongeni ngemuva kwazo. With izikhulumi etafuleni lami ekhishini - ideskithophu efanisiwe, uma uthanda - ama-bass akhishwe kancane futhi umsindo wawulinganisela kangcono. Noma kunjalo, bekungeke kungikhathaze uma le unit inesisindo esincane sokujula.
Idwala elingaphezu kakhudlwana ngivumele ngihlole imingcele eguquguqukayo yesistimu. Njengoba i-Cult's Electric egcwele ukuqhuma, ngaphawula ukuthi i-treble yayinomsindo omncane futhi engenalutho, futhi yayigxile kakhulu, kepha nokho, izinga eliphezulu elizwakalayo lilingcono kunokuthi iningi lazo zonke izinhlelo ze-Bluetooth ngiye ihlolwe. Ukusheshisa ukulalela "i-Rosanna" kaToto kuqinisekisile ukuthuthumela okuncane; kuzwakala kuhle, kungenayo "imibala ekhonjiwe" (umphumela wephuzu eliphakeme kakhulu eliphakathi kwe-woofer ne-tweeter), akukho ukuphazamisa okuphawulekayo kwe-tweeter, noma nanoma yimiphi imisindo evamile ebonisa ukuthi ikhositiki eshibhile, engenakunqunywa etholakala imikhiqizo yomsindo wesabelomali.
Nokho, ngaqaphela ukuthi lapho ngicwila uhlelo ngokugcwele, ngangizwa umsindo omncane ovela ohlelweni lapho kungekho mculo odlala khona.
Ngangizibuza ukuthi ngabe ngizozwa yini ukuqhuma okukhulu uma ngifaka ukuqoshwa kwe-jazz ehamba phambili, ngakho ngidlala umdlali we-saxophonist ka-AWESOME LISTEN KUYE MANJE MANJE "Hlabelela Ingoma Yengoma." I-Yep, i-Garrett's tenor yabe ishaya i-tad edgy, futhi amasimbali kaJeff "Tain" Watts 'ayengumncanyana kakhulu. Noma kunjalo, ngithanda umsindo jikelele; i-stereo imaging kanye ne-soundstage kwakungamangalisa futhi uhlelo oluncane lwalunezinto eziningi ezanele zokusingatha amandla amakhulu njengoba i-quartet yakha amandla ayo ngesikhathi sikaGarrett.
Ngabe sengicabanga. Ngangicabanga ukuthi "Hlabelela Ingoma Yomculo" kusuka efonini yami ye-Samsung Galaxy III, enezinhlelo zokusebenza eziningi zokulinganisela. Ngisebenzisa nje uhlelo lokusebenza olulula lwe-EQ olufakwe efonini, ngadonsela phansi--1.5 dB ku-3.6 kHz. Ukuphelela. Manje ibhalansi ye-tonal izwakala kahle, amaphutha we-tweeter ayengabonakali kalula, nokho umsindo wawusenomdla futhi ukhululekile.
Ngakho-ke ngenkathi uhlelo lwe-Grace Digital lunamaphutha, ngiyibamba kakhulu. Abanye bavuma kakhulu: Amathrendi eDanethi anike izinkanyezi ezingu-4 futhi i-PCMag.com yanike izinkanyezi ezingu-4. Ukuthungelwa kwamanye amanothi amaningi okungaxhunyiwe okubhaliwe? Yebo, i-missingremote.com yakutholile.

Abathengi be-Grace Digital Bluetooth Stereo: Izindlela
Impendulo yephindaphindiwe
on-axis: ± 5.0 dB kusuka 72 Hz kuya 20 kHz
isilinganiso: ± 4.8 dB kusuka 72 Hz kuya 20 kHz
MCMäxxx izinga eliphezulu lokukhipha
97 dBC ku-1 imitha
I-trace eluhlaza okwesibhakabhaka ibonisa impendulo yemvamisa ye-GDI-BTSP201 kwi-axis. I-trace eluhlaza ibonisa izilinganiso ezimpendulo eziphindwe kasikhombisa ezithathwe kwindwangu yokulalela e-± 30 ° enezingqimba. Ngokuvamile, umugqa ohlaza okwesibhakabhaka (on-axis) kufanele ube njengendawo ephathekayo ngangokunokwenzeka, futhi impendulo eluhlaza (engalinganiselwe) kufanele isondele ku-flat, ngokunciphisa okunciphisa impendulo eguquguqukayo.
Kuze kufike ku-3 kHz, izilinganiso ze-GDI-BTSP201 zihamba kahle, kokubili-naku-axis. Ezimeni eziphakeme, impendulo iningi kakhulu, futhi inkulu kakhulu ku-8.5 kHz. Zonke izinkinga zingaphezu kwe-midrange, ngakho-ke amazwi kufanele azwakale ebushelelezi ngisho noma ezinye zezinsimbi zomculo ophezulu (ingxabano, isiginci se-acoustic, njll) zizwakala kancane.
Ufuna ukwazi ukuthi ngenze kanjani lezi zivivinyo? Indlela efanele. Kodwa ngokungathí sina, abantu, ngisebenzise i-analyzer ye-CLIO 10 FW ne-CLIO MIC-01 ebangeni elingu-1 imitha, ngilinganise isikhulumi sesokunxele kuphela. (Ngiphinde ngilinganise isikhulumi esifanele futhi ngithole ukuthi impendulo yayo ihambelana nesobunxele ngaphakathi kwe-1.5 dB.) Izindlela ezingaphezu kuka-200 Hz zenziwe ngokusebenzisa indlela ye-quasi-anechoic ukususa ukubonakala komsindo ezivela emvelweni ozungezile. Impendulo engezansi kwe-200 Hz ilinganiselwe ngokusebenzisa imishini yendiza yomhlaba, ne-mic eseceleni kwamamitha ayi-1 kusuka kwesipikha sesokunxele. Imiphumela engaphezulu kwe-200 Hz ifakwe ku-octave ye-1/12, imiphumela engezansi kwe-200 Hz ifakwe ku-1 / 6th octave. Izindlela zithathwe ezingeni lika-80 dB ku-1 kHz / 1 imitha (lokho engikujwayele ukukwenza kumikhiqizo emincane yomsindo), bese kufakwe kwisilinganiso se-0 dB ku-1 kHz yale shadi.
Lolu hlelo alukhiphi ngempela ivolumu engingayilindela kusuka kuyo, ngithi, isamukeli eshibhile namaminithi ama-minimonitors ahloniphekile, kodwa ngokuyinhloko ukuncintisana nezikhulumi eziningi ze-Bluetooth ezingcono. Esivivinyweni sami se-MCMäxxx - i-"Kickstart My Heart" yaseMötley Crüe ekhonkotha ngokuzwakalayo njengoba i-unit ingadlala ngenkathi izwakala ihlanzekile kahle, bese ilinganisa izinga elilinganiselwe emitha eli-1 - Ngithole i-DBC SPL engu-97.
