Ama-Watts angu-120 ngenani eliphansi?
Kukhona zonke izinhlobo ze-stereo amplifiers ezincane ezitholakalayo manje ngezindleko ezifanele kakhulu. Iningi libizwa ngokuthi yi-Dayton Audio, Lepai, Pyle noma i-Topping, futhi iningi libeka ama-watts angu-15 noma angu-20 ngesiteshi ngasinye. Uma kuqhathaniswa nama-mini-amp abafowabo, i-Dayton Audio DTA-120 iyinhlangano yamandla, ibeka inani elingu-60 watts ngesiteshi ngasinye ibe ngumthwalo we-4-ohm.
Iningi lalezi amps zisebenzisa ubuchwepheshe be-Class T amplifier, eliyigama lebhizinisi lokuhluka kweClass D -a topology engakwazi ukukhiqiza amandla amaningi ngenkathi ikhiqiza ukushisa okuncane kakhulu. Yilokho okuvumela lezi amps zibe ezincane kakhulu; ne-Class T, ayidingi ama-heatsink amaningi.
I-DTA-120 ibonakala iphakethe elincane eliphelele lesistimu yomsindo wedeskithophu, uhlelo lwegaraji, noma ukulawula i-pair of izikhulumi zangaphandle. Ngama-watts angaphezu kokuphambanisa kunamaminithi amaningi amancane, akufanele alahle amandla namandla okusebenza ngezikhulumi eziningi. Ibuye inezikhwama ezimbili zokukhishwa kwekhanda ekhanda ngaphambili kwe-1/8-intshi jack, eyodwa ye-1/4-intshi jack-ebonisa ukuthi ilula.

I-Dayton Audio DTA-120: Izici nama-Specs
I-DTA-120 ibonisa ukucaciswa okumangalisayo:
- I-Class T amp ulinganiswe ku-60 wpc ibe yi-oh ohms, 40 i-wpc ibe yi-oh ohms, kokubili ngamaphesenti angu-10 THD
- Ukufakwa kwe-analog stereo kwe-analog
- Izindlela ezinhlanu zokubopha mini zokuxhuma isikhulumi
- 3.5mm (1/8-inch) kanye ne-headphone 1/4-intshi ekhanda
- Ukunikezwa kwamandla angaphandle
- 2.1x 3.4 x 5.5 ku (hwd, amplifier)
- 1.2 lbs (amplifier)
Ngokungafani nezinye eziningi ze-mini-amps, i-DTA-120 i-amp amp. Ayinayo ukufaka kwe-USB, ayikho i-Bluetooth, ngisho nokufakwa kokubili kwe-analog. It has control volume, ngakho awudingi pre-amp for it. Ukusetshenziswa okujwayelekile kuhlanganisa ukuhlinzekela ukukhishwa kwe-analog kwekhompiyutha noma i-TV ukunika amandla isistimu encane yomsindo. Ungase futhi uxhume isamukeli se- Bluetooth noma i-AirPort Express ukuze udale uhlelo olungenantambo.
Ngesikhathi i-DTA-120 ikhona kuma-watts angu-60 ngesiteshi ngasinye, kungama-4 ohms. Ku-okhulumela o-8-ohm ovame kakhulu, kulinganiswe ku-40 Watts ngesiteshi ngasinye. Zombili izilinganiso zingamaphesenti ayishumi ukuphazamiseka kwe-harmonic, okuvumela i-Dayton Audio ukuthi icaphune izinombolo eziphakeme; ukulinganisa okunokwethenjelwa kuzoba ngamaphesenti angu-0.5 noma amaphesenti angu-1 THD.
Ngenkathi i-amplifier ngokwayo ihambelana kahle, ixhomeke ekuhlinzekeni kwamandla okuhlukile okuba mkhulu njengama amp. Noma kunjalo, ungafaka amandla phansi phansi noma kuphi lapho kuzobe khona.

I-Dayton Audio DTA-120: Ukusebenza
Phakamisa i-DTA-120 enezikhulumi ezihlukahlukene, njenge-Revel F206s, i- Rogersound CG4 noma i-Dayton Audio B652-AIR, ukuze uhlole ukusebenza kwayo konke okusebenzayo.
Kunzima ukulingana kumakhamera angabizi kangako ngoba, ngandlela-thile, kwenza ukuthenga amanani abizayo kubonakale kungcolile. Kuyinto evamile ukuthi ama-audiophiles asebenzise izikhathi ezingu-20 noma izikhathi ezingu-30 nge-DTA-120 (noma ngisho nangaphezulu) ukuthola amandla afanayo (noma ngisho nangaphansi kancane). Kungakhathaliseki ukuthi uyibheka kanjani, kunzima ukwenza icala ukuthi lezo amps zilethe izikhathi ezingu-20 noma ezingu-30 ukusebenza kwe-DTA-120 kwisicelo sokuhlala esivamile.
Lokho kusho ukuthi amacala okusebenzisa kahle i-DTA-120 afaka ukufakwa egaraji, noma egumbini lokulinda, noma endaweni ethile lapho ikhwalithi ezwakalayo ayinandaba. Amazwi ayezwakala kunomile futhi omncane nge-DTA-120. Izinsimbi eziphakeme kakhulu zomsindo zizwakala futhi ziqhekekile, ngokunye ukuphazamiseka emabhokisini lapho kuhlanganiswa neZembukiso zempahla ephansi njengeHolly Cole okuqoshiwe kwe "Train Song."
Ukuhlukanisa i-DTA-120 ne- Mengyue Mini (okubiza kakhulu) kuphakamisa ukuthi iMengyue Mini yazwakala kangcono cishe zonke izindlela, ihambisa ukukhanya, ukuhamba kwezemvelo nokunye okukhiqizayo kwezwi. Kwakhiqiza futhi umsindo ovulekile, ogcwele kakhulu; nomculo we-DTA-120 ubonakala sengathi uvela emkhakheni wezinsiza ezimbalwa kunokuba kube nemisindo yemvelo, eqhubekayo. I-mini yenze ama-bass amanothi aphansi kakhulu, kodwa-akumangalisi ukucabanga ukuthi kufana nawo wonke ama-tube amps, isebenzisa i-transformer okukhiphayo.
Zombili amps zanikeza ivolumu ngokwanele ngeziNtshumayelo, yize noma usebenzisa izikhulumi ezingafani kahle, zithi, 84 ukuzwela okungenani noma ngaphansi, i-Mini ingase ingadlali ngokukhululekile ngokwanele. I-DTA-120 inhle mayelana no-+6 dB okukhipha okungaphezulu-mhlawumbe akudingeki ukuze kube ne-desktop yomsindo, kodwa kuzoba khona ezindaweni ezikhudlwana.
Zonke izinto ezicatshangwayo, i-DTA-120 ingaba yisinqumo esihle sokusetha isimiso somsindo esinamandla kodwa esingabizi kakhulu egaraji noma endaweni yokusebenzela, noma njengendlela yokunika amandla izikhulumi ezithile zangaphandle. Akuyona uhlobo oluthile lwe-"audiophile bargain," kodwa lungcono kakhulu.
