naim制作
獨(dú)特的工廠制造流程
今天的Naim,在生產(chǎn)方式上有二處與眾不同,其一是從設(shè)計(jì)開(kāi)始一直到最后成品測(cè)試,都在工廠內(nèi)自己一手完成。當(dāng)然,這種作法需要很多的儀器與人才投資,不過(guò)它的好處是可以全程掌控,發(fā)現(xiàn)問(wèn)題立刻改進(jìn)。其二就是生產(chǎn)在線的工人并不是每個(gè)人只負(fù)責(zé)某部份的組裝,而是從零件的領(lǐng)取開(kāi)始,就由同一個(gè)人從頭到尾把這件產(chǎn)品組裝起來(lái),一直到成品測(cè)試完成。為什么要用這種方式呢。Naim說(shuō)這樣工人在工作時(shí)會(huì)比較有樂(lè)趣與成就感。此外,冤有頭債有主,哪部產(chǎn)品出了毛病都可以去找負(fù)責(zé)人。

naim功放個(gè)人感覺(jué)還是挺不錯(cuò)的,功放使用的時(shí)候高低音都很純、沒(méi)有太多嘈雜的聲音,聲音也很飽滿,還原度很高。產(chǎn)品使用操作起來(lái)也很方便,即使剛使用的人也可以很快熟練。產(chǎn)品的外觀也是很有質(zhì)感的,設(shè)計(jì)非常簡(jiǎn)...
krausnaimer轉(zhuǎn)換開(kāi)關(guān)好不好用?
你好,krausnaimer轉(zhuǎn)換開(kāi)關(guān)挺好用的,用轉(zhuǎn)換開(kāi)關(guān)代替刀開(kāi)關(guān) ??使用,不僅可使控制回路或測(cè)量回路簡(jiǎn)化,并能避免操作上的差錯(cuò),還能夠減少使用元件的數(shù)量。是用轉(zhuǎn)換開(kāi)關(guān)代替兩...
