Ama-Audiophiles nabathandi bomculo abathandekayo bavame ukuvula ama-amplifiers ahlangene njengendawo ephakathi kokusebenzisa isitholi se-stereo kuphela uma kuqhathaniswa nezinto ezigcwele ezihlukene. I-receiver yedwa inganikeza konke into eyodwa, kepha ama-purists athi ukusebenza okuphansi okuphansi kuncike kwezinye izici ezengeziwe. Ubuhle bokuzikhethela ngezandla izingxenye ezihlukene ukuthi ungakha uhlelo olukwazi ukuletha imizwa yomsindo ozwakalayo. Kodwa ingabe kunzima? Lindela ukukhokha izintengo ezithile zebhajethi-busting.
Amaphuzu ahlanganisiwe yiyona phuzu eliphakathi eliphakathi kwezingxenye eziyingqayizivele neziningi. Ama- amplifiers anjalo ahloselwe ukwenza ngcono ukusebenza komsindo , kodwa ngokuvamile ngentengo ebiza kakhulu kunam amp amp and preamp. Esinye isibonelo esinjalo yi-Yamaha A-S500. Ngikunikeze kanzima ukuze ngithole indlela egcina ngayo njengesikhulumi esihlanganisiwe esinezindleko ezididiyelwe.
Izici
I-A-S500 ingenye yezinto zika-Yamaha ezithengeka kakhulu, amanani okukhulisa. Ukubukeka okuhlanzekile, okungenakunyakaziswa kwe-A-S500 ukuphonswa kokuqala kwe-stereo amps kanye nokwamukelwa kwe-Yamaha eyethulwa e-US phakathi nawo-1970. Iphaneli layo elimnyama, elimnyama elimnyama kanye nemigqoko eminyene yomabili iyamangalisa futhi i-classy.
Uma ulindele ukuxhuma kwimithombo ye-digital , ngeke ube nenhlanhla njengoba i-Yamaha A-S500 i-amplifier kuphela. Kodwa iphakamisa ama-watts angu-85 womunye wesipikha, esilinganiswa kusuka ku-20 Hz kuya ku-20 kHz enezikhulumi ezingu-8-ohm, okungaphezu kokwanele izikhulumi ezinombono wokuzwela okungaba ngu-92 dB noma ngaphezulu. I-Yamaha A-S500 ine-bandwidth yamandla esuka ku-10 Hz kuya ku-50 kHz kanye ne-humid factor factor kuka-240. I-amplifier ye-A-S500 iphinde ibonakale: ukukhishwa kwe-subwoofer, ukufakelwa kwe-iPod Dock ngokunikezwa kwamandla okuhlukile ku-amp , i-REC Sula umkhethi wokurekhoda nokulalela imithombo ehlukene ngesikhathi esisodwa, kanye nomsebenzi oqondile we-Pure owandisa impendulo yemvamisa kusuka ku-10 Hz kuya ku-100 kHz ngenkathi inikeza indlela yesignali eqondile kakhulu. Mane ukhumbule ukuthi ama-specs awasho indaba yonke, ekhonza nje njengendlela yokuqondisa yokuhlola ukusebenza komsindo.
Ezinye izici eziyinhloko zifaka phakathi: izimpikiswano ezimbili zezikhulumi zezikhulumi ezimbili (noma i- bi-wiring ibhangqa elilodwa ), i-phono input ( ihamba ngamagnetti we-magnnet cartridge kuphela), kanye nomsebenzi wokuLawula amandla oshintshela i-A-S500 kumodi yokulinda emva kwamahora ayisishiyagalolunye kokungasebenzi. Esinye sezici engizikhonzile yi-Controling Muting, okuyithulisa kancane kancane umsindo ngaphambi kokubuyisa kancane kancane umsindo osezingeni langaphambilini uma kukhishwa. Kuyinto engafanele kakhulu ukukhipha kunokulawula okulula okuyi-MUTE okuyi-off-off. Okuhlanganisiwe okulawula kude futhi kusebenza ezinye izingxenye ze-Yamaha, njenge-tuner yomngane we-T-S500 noma umdlali we-CD / i-DVD.
Ukusebenza
Ngahlola i-A-S500 ngombhangqwana wezikhulumi ze-Axiom Audio (96 dB ukuzwela) kanye ne-Atlantic AS-1 izikhulumi zombhoshongo (89 dB ukuzwela), okubhekwa njengolubanzi obubanzi lwezinkomba zokuzwela ukukhuluma. I-amplifier ehlanganisiwe ye-Yamaha A-S500 akakaze ibonakale ihambisana nesipikha - nakuba ngingangabazi ukunikeza izikhulumi zase-Atlantic amandla angaphezulu. Amazinga wokulalela yindaba yokunambitheka komuntu siqu, ngakho-ke ngaphandle uma ubeka amandla izikhulumi ezine ( Abathengi A + B ) emazingeni aphakeme kakhulu, i-amplifier ye-Yamaha A-S500 iphelele ngokwanele ukuba ingabikho uhlobo lokukhishwa. Uma kunamandla amaningi adingekayo kuzikhulumi ezithile kanye / noma izintandokazi zakho, ungase ufune ukuhlola i -amplifier ehlanganisiwe ye-Analog A-S1100 .
Ngokuvamile i-Yamaha A-S500 inekhwalithi yomsindo olinganiselayo nakancane. Ukulawulwa Okuphakanyiswa Okuqhubekayo Okuqhubekayo, okutholakala ezingxenyeni eziningi ze- stereo ze- Yamaha, kuphumelela kakhulu uma uzama ukuthola ibhalansi ye-tonal efanele. I-A-S500 ihlanganisa kalula nge-iPod dock yokuzikhethela, njenge-Yamaha YDS-12 (futhi i-YDS-10 no-YDS-11) Idokodo le-iPod / iPhone yonke. Isilawuli esikude esihlinzekwe nge-Yamaha A-S500 sikwazi ukulawula imenyu nemisebenzi eminingi yokudlala ye-iPod ekhonjiwe noma i-iPhone (nakuba kungekho okukhipha ividiyo). Njengoba nje abathengi bezimoto bevula futhi bevale umnyango wemoto ukuze bathole umuzwa wekhwalithi, abathengi bezomsindo bathanda ukuvula amafindo bese bashaya izinkinobho zezingxenye. Kule ndawo, i-Yamaha A-S500 iyahamba kahle ngokulawula okuletha ukuzwa okubushelelezi, okuthinta.
Isiphetho
Ukondla ukudlala kwe-audiophile kungaba yinselele. Kodwa nge-amplifier ehlanganisiwe ye-Yamaha A-S500, ayidingi imali engenamkhawulo. Leli yunithi lingaba yitshe legumbi le- stereo elimnandi elibambe isabelomali esiqinile . Ngesikhathi i-A-S500 ingeke iphakamise izinga le-Hi-Fi yezingxenye ezihlukene, linikeza ukusebenza kanye nezici ezithatha isitezi kusuka kubamkeli be-stereo ekilasini elifanayo. Uma kuhlangene ne-pair of izikhulumi ezithengiwe ngokwezifiso kanye nomthombo (phono, CD, noma i-DVD), i-Yamaha A-S500 ingakwazi ukukhonza kalula izidingo kanye nezidingo zomlaleli womculo ongathà sina ngaphandle kokuphula ibhange.
