120 Watts ngexabiso eliphantsi?
Kukho zonke iintlobo ze-stereo amplifiers ezikhoyo ngoku ngeendleko ezifanelekileyo. Uninzi lubizwa ngokuba yi-Dayton Audio, iLepai, i-Pyle okanye i-Topping, kwaye ininzi ikhupha i-15 okanye i-watts ezingama-20 ngomjelo. Xa kuthelekiswa nabazalwana babo be-mini-amp, i-Dayton Audio DTA-120 iyinkosi yamandla, ikhupha ireyiti ezingama-60 nganye kwisitya sibe ngumthwalo we-4-ohm.
Ininzi yalezi zixhobo zisebenzise iteknoloji yokukhulisa i-Class T, eyigama lezorhwebo ngokuchaneka kweClass D- topology engakwazi ukuvelisa amandla amaninzi ngelixa ivelisa kakhulu ukushisa kwenkunkuma. Yiloo nto evumela ukuba le i-amps ibe yincinci kakhulu; kunye neklasi yeT, ayifuni i-heatsink enkulu.
I-DTA-120 ibonakala ipakethe encinci yeprogram yomsindo wedesktop, inkqubo yegaraji, okanye ukulawula ibini lezivakalisi zangaphandle. Ngama-watts amaninzi kwipompo kunezona ezininzi i-amps-amps, akufanele ilahleke amandla kunye neenkuthazo kunye neentetho ezininzi. Kwakhona i-packphone ye-headphone ipake kwi-front-eyodwa ye-1/8-intshi jack, enye i-1/4-intshi-jack-ebonisa ukuba ikulungele.

I-Dayton Audio DTA-120: Izixhobo kunye neenkcukacha
I-DTA-120 ibonisa iinkcazo ezimangalisayo:
- Iklasi ye-T ilinganiswe kwi-60 wpc kwi-oh ohms, 40 i-wpc kwi-8 ohms, zombini kwi-10 ekhulwini THD
- I-RCA stereo input analog
- Izithuba ezinhlanu zokubophelela ezincinci zokuxhumeka kwesithethi
- 3.5mm (1/8 intshi) kunye ne-headphone ye-1/4 intshi
- Ukunikezelwa kwamandla angaphandle
- 2.1x 3.4 x 5.5 kwi (hwd, amplifier)
- 1.2 lbs (amplifier)
Ngokungafani nezinye ezininzi i-mini-amps, i-DTA-120 i-amp amp. Ayinayo i-input input ye-USB, akukho Bluetooth, kungekhona nese-analog input input. Inokulawula umthamo, ngoko awuyidingi i-pre-amp yayo. Ukusetyenziswa okuqhelekileyo kubandakanya ukulungiswa kwemveliso ye-analog yekhompyutha okanye iTV ukunika amandla inkqubo encinci yesandi. Unokudibanisa ummkeli weBluetooth okanye i-AirPort Express ukudala inkqubo ye-wireless.
Ngoxa i-DTA-120 iqhutywe kwi-watts ezingama-60 ngeeseshoni, ezi-4 ohms. Kwi-o-ohm isithethi esiqhelekileyo, isilinganisiwe kuma-watts angu-40 ngeseshini. Zomibini izilinganiso zingama-10 ekhulwini ukungaziphambuki kolunye uhlangothi, okuvumela i-Dayton Audio ukucaphula amanani aphakamileyo; Ukulinganiswa okunyanisekileyo kuya kuba kwi-0.5 ekhulwini okanye 1 iphesenti ye-THD.
Nangona i-amplifier ngokwayo ibonakala idibeneyo, ithembela kumbane wonikezelo lwamandla olwahlukileyo ophezulu ngokubanzi. Nangona kunjalo, unako ukubeka amandla kumgangatho phantsi okanye naphi apho kuya kuba khona.

I-Dayton Audio DTA-120: Ukusebenza
Idibanisa i-DTA-120 ngeentetho ezininzi ezahlukeneyo, njengeRevel F206s, i-Rogersound CG4 okanye i-Dayton Audio B652-AIR, ukuvavanya ukusebenza kwayo kwendodana.
Kunzima ukulungelelanisa kumaxabiso angabizi kangangoko, kuba, ngandlela-thile, yenza ukuthengwa kwamaxabiso amanani abizayo kubonakala kungonakalisi. Kuqhelekile ukuba i-audiophiles ichithe amaxesha angama-20 okanye ama-30 amaxabiso e-DTA-120 (okanye nakwezinye iindlela) ukuze ufumane umlinganiselo ofanayo wamandla (okanye kwindlela encinane). Kungakhathaliseki ukuba uyayicinga njani, kunzima ukwenza ityala ukuba loo ma-amps ahlawule amaxesha angama-20 okanye ama-30 ekusebenzeni kwe-DTA-120 kwisicelo sokuhlala ngokuqhelekileyo.
Oko kwathiwa, iimeko ezifanelekileyo zokusetyenziswa kwi-DTA-120 zibandakanya ukufakwa kwigaraji, okanye kwigumbi lokulinda, okanye kwindawo apho uphuculo oluphezulu olungathandekanga. Iimvalo zandila kunokuba zome kwaye zincinci nge-DTA-120. Iimpahla eziphakamileyo ezivakalayo zivakala kwaye ziqhekeza, kunye nokuphazamiseka kwezinye iibhasi xa zidibene kunye neNtshumayelo yezinto ezihlambulukileyo ezifana nokurekhodwa kukaHolly Cole othi "Qeqesha ingoma."
Ukwahlula i-DTA-120 ukuya kwiMengyue Mini (ebiza kakhulu) iphakamisa ukuba iMengyue Mini ibonakale ingcono phantse yonke indlela, ihambisa i-lusher, ihamba ngokunyuka kwemvelo kunye nokuveliswa kwezwi elihle. Kwakhona kwavelisa i-soundstore elula, ephezulu; kunye nomculo we-DTA-120 ubonakala ngathi uphuma kwiqela lezinto ezincinci zokufumana indawo engaphezulu kwendalo. I-Mini yenze i-little looser, i-less defined defined bass, nangona kunjalo-akumangalisi ukuba ucinga ukuba kufana nayo yonke i-tube amps, isebenzisa i-transformer output.
Zombini iimps zanikela ivolumu ngokwaneleyo kwiimvelaphi, nangona ukuba usebenzisa izithethi ezingafaniyo, zithi, u-84 dB uvakalelo okanye ngaphantsi, i-Mini ingakwazi ukudlala ngokukhawuleza ngokwaneleyo. I-DTA-120 ilungile malunga ne-+6 dB emveliso engaphezulu-mhlawumbi ayifuni kwi-desktop yomsindo, kodwa iya kufikeleleka kwiindawo ezinkulu.
Zonke izinto ezicatshangwayo, i-DTA-120 iya kuba yinto ekhethekileyo yokumisela inkqubo ephilileyo enamandla kodwa engabizi kwigalaji okanye kwindawo yokusebenzela, okanye njengendlela yokunika amandla ezinye izithethi zangaphandle. Akunjalo uhlobo oluthile lwe "audiophile bargain," kodwa lusetyenziso olungcono.
