Asi vamwe vanhu vakaramba vachida stereo receiver yepamutemo - uye vatengi vanogadzira vaiziva izvi. Imwe yakadaro ndiyo Yamaha R-S700 stereo receiver, iyo inotora chinangwa kune vanofarira avo vanonyanya kufunga nezvezvinhu zviviri zvinobudiswa .
Mukufarira kwekujekesa zvizere, ndakashandira Yamaha kwemakore anoverengeka uye ndine zvikamu zvishoma zveComposer. Asi semuongororori wemagariro, unogona kuverenga pane zvekutendeseka.
The Basics
Yamaha stereo receivers akawana mukurumbira wakanaka achidzokera kuma1970. Ndakaona yakashandiswa Yamaha CR-820 stereo inogamuchira necheperi sirivha yepamberi panhivi (pakati pemakore ekuma1970) kutengeswa pazvitoro zvekugadzira TV vasati vasvika (mumamiriro ezvinhu akanaka, zvakare). I-R-S700 inokanganisa kuma1970-era Yamaha sevhisi uye yakachena, isina tsvina pamberi pepane uye yakanakisa-yakashongedzwa nemakumbo uye kutonga. Asi zvakasiyana-siyana zvinosanganisira zvinoshandiswa patsva uye jet-black faceplate.
Iko Yamaha R-S700 inokwanisa kutora 100-watts per channel kusvika paviri ye 8-ohm speakers. Uyu anogamuchirwa anogona kunge akaenzana nevatauri seanotsika se 4 ohms kuburikidza ne an impedance selector switch kushure kwepanepa. Mutauriri A, B kana A + B zvinoreva maviri maviri e 8-ohm kutaura anogona kusimbiswa panguva imwechete, iyo inopa zvimwe kuwedzera kushanduka. Bi-wired speaker connections inogonawo kuita ne -bi-wire anokwanisa kutaura .
Zvitanhatu zvinyorwa zvekare (CD, tape, phono, zvitatu zvinobatsira, uye zviyero zviviri zvinobatsira) zvakakwana kumagadziriro akawanda, uye Rec Out inoitwa inoita kuti zvive nyore kunyora imwe nzvimbo apo ichiteerera kune imwe. Zvakakodzera, iyo Yamaha R-S700 haina digital audio circuitry - inongova chikamu cheanorog chete yakagadzirirwa kuchengetedza kuchena kwechiratidzo uye kujekesa. Iwe unofanirwa kushandisa shanje mbiri-mitsara yekubudiswa kwe disc disc kuti ubatanidze kugamuchirwa kana kuvandudza kune imwe kunze yedhigiri kune analog converter (DAC).
Zvinhu zvakagadziridzwa
Kusiyana kukuru pakati pemakore 70 e-receivers Yamaha uye R-S700 inzvimbo ye -multi-zone / multi-source , iyo inobvumira munhu kune imwe nzvimbo kunoteerera kune zvakasiyana zvakasiyana pane iyo yekamuri huru. I-R-S700 mutevedzeri weasina simba reEnget 2 yakabuda inoda amp amp uye vaviri vakurukuri munharaunda yechipiri. Icho chinouya nechekare Zone 2 yekudzivirira kwekushandisa kushandisa mutambi kubva pane imwe imba. Gara uchiyeuka kuti nzvimbo dzakasiyana-siyana inoshandiswa dzinoda kushandiswa nhaurirano dzemhepo uye IR (infrared remote) kutonga faira kubva kuChikoro 1 kusvika kuChechi 2, iyo inogona kudikanwa unyanzvi hwokugadzira.
Menyu yekusarudza ine maitiro akasiyana-siyana ezvinyorwa zvose zvekushandisa zvinosanganisira: hukuru / zviduku uye mavhesi ekutanga pane imwe nharaunda, + 12-volt Trigger Out, Sirius Satellite Radio , uye mamiriro e iPhone / iPod nokuda kwekuita wired ne wireless.

Iko Yamaha R-S700 inewo mavhidhiyo evhidhiyo anobudiswa kuti utarise iPod mavhidhiyo kana kutumidzwa zvayo pane terevhizheni kana kuongorora. Ingoyeuka mupfungwa kuti iPod / iPhone opera zviratidzo haisi kuratidzwa.
Test Drive
Izvo zvakanakisisa zvinogadziriswa stereo zvinosanganisira zvitatu zvinokosha zvinokosha: huru, inzwi rakagadzirwa zvakanaka, uye iri nyore kushanda.
