Ntchito Yabwino Kwambiri pa Super Subofofer Imapindulabe
HSU Research's original VTF-15H subwoofer mwina inali yotsika mtengo yotsika mtengo yomwe ingaganizidwe kuti ndi yapamwamba kwambiri ya subwoofer yomwe ili ndi zochuluka zowonjezera ndi kuzungulira kwakukulu kotero kuti zinali zovuta kuzikankhira ku malire ake, mocheperapo kuzidutsa. Komabe, pa 2014 Rocky Mountain Audio Fest, HSU Research inadabwitsa anthu onse omwe ali ndi VTF-15H MK2, yomwe imasinthidwa ndi kusinthidwa kwa subwoofer.
Mphamvuyi inachotsedwa kuchokera ku Watts 350 ku RMS mpaka 600 Watts RMS-kusiyana komwe kukupatsani mowonjezereka +2.3 dB zochuluka zowonjezera, poganiza kuti dalaivala akhoza kuthana nazo. Kuti athandize kugwiritsira ntchito mphamvu yowonjezera, dalaivala ali ndi maginito omwe HSU Research amati imakhala yachiwiri kukula kwa imodzi pachiyambi VTF-15H. Zotsatira za XLR zogwiritsira ntchito stereo zowonjezera zinawonjezeredwa, ndipo kutentha kwazing'ono kunamangirizidwa kumbuyo.
Chitsanzo chatsopano chimasinthidwa pang'ono muyeso yake. Ndimphindi wamfupi, zomwe zimapangitsa HSU Research kuti apeze mtengo wotsika pa kutumiza. Mtengo wa chigawochi unapita, koma ndalama zotumizira zinatsika, motero chitsanzo chatsopano chinatha mtengo wofanana ndi umene unayambitsanso.

HSU Kafukufuku VTF-15H MK2: Zizindikiro ndi Ergonomics
Zochitika ndi ergonomics za VTF-15H MK2 ndizochititsa chidwi:
• woyendetsa masentimita 15
• Watsi 600 a RMS BASH (Class G) amplifier
• Machitidwe asanu akumvetsera ndi kusintha kwa EQ
• Zipulositiki ziwiri zotsekemera zilipo
• kusintha kwa Hertz crossover mpaka 30 mpaka 90
• Kulamulira kwa 0.3 mpaka 0.7 Q
• Zotsatira za RCA ndi XLR stereo analog
• Zithunzi zisanu zokumangiriza zolemba za stereo speaker level
• Miyeso: 24.5 x 17.25 x 28 mu / 623 x 438 x 711 mm
• Kunenepa: 110 pounds / 49.9 kg
Mofanana ndi chitsanzo choyambirira, VTF-15H MK2 ili pafupifupi mbali iliyonse imene mungafune mu subwoofer . Ndi kusintha kwa EQ ndikukwanitsa kuyendetsa, chidindo chimodzi chimatseguka kapena ma doko awiri otseguka, muli ndi njira zisanu zogwiritsa ntchito. (Simungathe kuyendetsa ndi ma doko onse otseguka pa malo EQ1.)
Kuwonetsa Max Output (ma doko awiri otseguka, EQ2)
Kuwonjezera Max Extension (1 yotseguka lotseguka, EQ1)
Anayang'ana Max Headroom (1 yotseguka, EQ2)
Kusindikizidwa kwa Max Max (ma doko 0 otseguka, EQ1)
Mutu Waukulu Wosindikizidwa (ma doko 0 atseguka, EQ2)
Subwoofer imakhala ndi zowonjezera zambiri, koma ziribe zotsatira, kotero simungathe kuyendetsa chizindikiro chododometsa kwambiri kwa okamba anu apamwamba. Ntchito yamapamwamba imachokera pansi pa okamba anu apamwamba. Muyenera kuchita zambiri pamtundu wa A / V wanu, mugwiritsire ntchito ndondomeko yakunja, kapena muthamangitse kukwera kwa wokamba wanu wamkulu ndikuyika mafupipafupi a VTF-15H MK2 kwa malire anu osankhidwa apamwamba .
The VTF-15H MK2 ili ndi vuto limodzi lokha, ndipo ndilo mawonekedwe ake. Pa masentimita makumi asanu ndi awiri, imamangiriza njira yopita kuchipinda, koma ndi zina zambiri zomwe zimapititsa patsogolo.

HSU Kafukufuku VTF-15H MK2: Kuchita
Ogwiritsa ntchito VTF-15H oyambirira amakukonda. Ma subsist ochepa amaposa kupimidwa kwake ndi dB kapena awiri, ndi zochepa zowonongeka mozama komanso zowonjezereka, koma zonsezi ndizofunika kwambiri. The VTF-15H MK2 imamveka mofanana ndi yomwe idakonzedweratu. Kuyerekezera pambali ndi mbali, kusiyana kochepa pang'ono kwa vidiyoyi kunapangitsa kusiyana kwakukulu mukumveka kusiyana ndi kusinthasintha subwoofers. Kulembera ndi zazikulu zoposa 100-pounds zolemera zinapangitsa kuti ntchitoyo ikhale yovuta kwambiri kuti kukumbukira kwazomwe zinali kuyesedwa kutsutsana kunali kuyamba kutha.
The VTF-15H MK2 ikugwedeza pansi pang'onopang'ono pamene gawolo lidutsa pansi pa woononga ndipo limatulutsa mfundo zozama kwambiri. Ndizowopseza pang'ono zomwe zing'onozing'ono zingathe kuchita, ndipo gawo lapamwamba ndi pafupifupi +3 dB zambiri zomwe zimatuluka ndizowopsya. Chipinda sichimangogwedeza, chimagwedeza. Mutha kumva ndikumva ngakhale makoma ndi denga akusuntha pang'ono. Mafilimu ena amatsutsana ndi vutoli, komabe kunyumba kwamasewera , ndizofunikira kwambiri chifukwa ndizoona zenizeni kuposa zomwe angakwanitse.
The VTF-15H MK2 imasunga chimodzi mwa zinthu zoyambirira zomwe oyang'anira amakonda: zowoneka bwino. Mukhoza kuwamveka molimba kwambiri ndi kulumikiza phokoso podula ma doko awiri ndi kutembenuza Q, kapena mukhoza kumveka phokoso ndi kutsegula phokoso pogwiritsa ntchito malo amodzi kapena awiriwa kutsegula ndipo mwinamwake mutembenuza Q pang'onopang'ono. Simumangokhala ndi liwu limodzi lokha kapena mtundu umodzi wa sub.
Chigawo chimodzi chokongola chomwe chimamveketsa "nyimbo" zambiri-monga VTF-15H yapachiyambi ndi SVS PC13-Ultra, yomwe imakhala kawiri mtengo wa VTF-15H MK2. Maseŵera ochepa omwe ali ndi madalaivala 15-inchi amadziŵika chifukwa cha kutanthauzira kwake, koma mfundo yakuti mtengo wamtengo wapatali kwambiri wa 13-inch amagwiritsa ntchito njira zowonongeka zokhazokha m'dera lino ndi kupambana kwenikweni kwa HSU Research design.
