Yiluphi uhla lokujiya kophahla okungamukelwa izipikha zasephahleni ze-OPA in-ceiling?
Izinkunzi ze-OPA ze-satellite speaker ziklanyelwe ukulingana nodonga olujwayelekile lwe-drywall, ngokuvamile zithatha ubukhulu obusuka ku-12mm kuya ku-30mm ngama-clamps afakiwe. Ezintweni ezijiyile zophahla ezifana namapulangwe noma i-double-layer drywall, ama-spring-loaded dog-ear clamps asengakuqinisekisa isipikha ngokuqinile uma nje ubukhulu obuphelele buhlala phakathi kwebanga elinqunyiwe. Abafaki kufanele bahlale behlola imfuneko yokujula kokusika ukuze baqinisekise ukuthi kukhona isikhala esanele se-plenum ngaphezu komgodi wophahla ukuze umzimba wesipikha ungene. I-OPA inikeza imininingwane enembile yayo yonke imodeli ekhasini Lemikhiqizo, ivumela abahlanganisi ukuthi baqinisekise ukuhambisana ngaphambi kokusika noma yiziphi izimbobo. Uma isakhiwo sophahla singajwayelekile, usekelo lobuchwepheshe be-OPA lungatusa izinsiza ezifanele ukuze kuqinisekiswe ukufakwa okuphephile.
Ngingakwazi ukwenza ngokwezifiso umbala we-grille noma ngangeze ilogo yomkhiqizo ezipikheni zasephahleni ze-OPA ceiling satellite?
Yebo, umnyango wangaphakathi we-OPA wokwenza ngokwezifiso unikeza izinketho eziningi zamaspika asemgqeni wesilingi, okuhlanganisa imibala yegrille engokwezifiso, ukuphela okuthintwayo, namalogo anegama lomkhiqizo. Inkampani ingafanisa umbala we-Pantone womkhiqizo wakho ngqo kugrille mesh, noma isebenzise ilogo eprintiwe ngesilika ukuze ithole ukuphela okuhle nokuhlala njalo. Ukuhlelwa kwama-driver, ama-wattage taps, kanye nokujula kokufakwa nakho kungashintshwa ukuze kuhlangatshezwane nezidingo zobunjiniyela zephrojekthi ethile. Leli zinga lokwenza ngokwezifiso lenza i-OPA ibe ukukhetha okuhle kakhulu kumahhotela, amakhasino, namaketanga ezitolo afuna isixazululo somsindo esinegama lomkhiqizo noma esiphelwe ngendlela ehlukile. Ukuze uxoxe ngemininingwane yephrojekthi yakho, thintana nathi ngekhasi le-Customize futhi uthole isilinganiso esinemininingwane ngosuku olulodwa lwebhizinisi.
Yiliphi iwaranti nokusekelwa kwezobuchwepheshe okunikezwa yi-OPA ngezikhulumi zayo zesilingi ezisemkhathini?
I-OPA isekela isipikha ngasinye se-ceiling satellite speaker ngewaranti enkulu yomkhiqizi ehlanganisa ukukhubazeka kwezinto zokwakha nokusebenza ngaphansi kokusetshenziswa okuvamile. Isikhathi esijwayelekile sewaranti sihlanganisa wonke umshini we-driver ne-cross-over assembly, kanti i-grille nezingxenye zobuhle zivikelwe ekukhubazekeni kokukhiqiza. Ngaphezu kwewaranti, i-OPA inikeza ukwesekwa kobuchwepheshe kwempilo yonke kubahlanganisi nabasebenzisi bokugcina, okuhlanganisa ukuholwa kokufaka, usizo lwezintambo, nezeluleko zokuxazulula izinkinga. Ithimba lokweseka le-OPA lingatholakala ngezindlela zokuxhumana zenkampani, futhi ikhasi le-News livame ukushicilela izaziso zesevisi nezibuyekezo ze-firmware zezinhlelo zomsindo ezihambisanayo. Lokhu kuzibophezela ekunakekelweni kwangemva kokuthengisa kunikeza amakhasimende e-OPA ukuzethemba kwesikhathi eside ukuthi utshalomali lwabo lomsindo luzosebenza ngokuthembekile iminyaka eminingi.
Ngingakuthola kanjani ukubekwa okufanele kwebanga phakathi kwezipikha ezimbili ze-ceiling satellite?
Endaweni evamile yokulalela i-stereo, i-OPA incoma ukuthi izikhulumi ezimbili zophahla ezisemaceleni zibe nebanga elingamafidi ayisithupha kuya kwayishumi, kuye ngobude bophahla nosayizi wegumbi. Izikhulumi zangakwesokunxele nangakwesokudla kufanele zibekwe zilingane ukusuka endaweni yokulalela emaphakathi ukuze kube nomfanekiso we-stereo olinganiselayo. Emakamelweni aphakeme anophahla olungaphezu kwamafidi ayisishiyagalolunye, ibanga linganwetshwa kancane, kodwa izikhulumi kufanele zisalibheke endaweni yokulalela ngama-swivel tweeter azo. Ezinhlelweni zokusabalalisa umsindo, izikhulumi zivame ukubekwa ibanga elingamafidi ayisishiyagalombili kuya kwayishumi nambili ukuze zinikeze ukumboza okulinganayo nokuhlangene. Ukuthatha izilinganiso ezinembile ngaphambi kokufaka nokulungisa ama-tweeter angles ngemva kokufakwa kuzoletha ukuthuthuka okubonakalayo ekucabangeni nasekufaneni kwethoni.
