膽機分類 Transformer output (OPT)
用火牛去step down 部amp 輸出阻抗。可以用線路分類成單端、推挽、單端並聯。一般情況下,大部分耳牛使用單端線路已足夠推力應付。以下再介紹各款線路:
A. 單端放大電路(Single Ended) 全意是一支單端管 (例如 300B, 2A3 )以單一放大電路之意, 一部 Stereo 純單端機, 就只有兩支單端管。單端機種主要以音色為主, 動力為次, 無論播放哪一類型錄音都好, 高頻音色都很美, 整體音色艷麗嬌美。


(圖為一部單端2A3耳擴膽機)
B. 推挽放大電路 (Push Pull) 推挽式膽機後級放大管一般多用於 EL-34 ( 6CA7 ), 5881 ( 6L6 ), KT-88, 6550, 6V6, EL-84 ( 6BQ5 )等等, 選擇比單端機多, 推挽式放大電路必需要有逐行倒相制電路, 這份電路不易做出對稱的波形, 因此經過推挽級輸出的波形也絕不及單端電路波形對稱, 雖是如此, 但市場上推挽機較普及, 大部份中價機種都是推挽機居多, 好處是線路簡單, 功率足夠, 推動力較好, 音色具足夠厚度。


(圖為一部推挽45耳擴膽機)
C. 單端並聯(Parallel Single Ende)&並聯推挽 (Push Pull Parallel), 因為推挽波形不及單端而推出, 好處是集各項電路的優點加以改良而成,缺點係機種通常都做到好巨大。


(圖為一部並聯推挽 300B耳擴膽機)
膽機分類 Output transformerless (OTL)
不使用火牛,使用膽前後石或石前膽後純輸出
膽的內阻普遍比較大, 某些內阻最小的管子如三極管2A3之類的也要大幾百歐,如果不用變壓器去匹配阻抗,那傳遞給低阻喇叭/耳牛的功率會很小,大部分都消耗到膽內部了。所以膽機一般都要配輸出變壓器。OTL的意思就是不用輸出變壓器,那純膽輸出想OTL,就得多對膽並聯,一般要5對以上,甚至10對以上,才勉強可以跟喇叭/耳牛的阻抗相提並論。所以膽很少用OTL。電晶體內阻極低,遠小於喇叭/耳牛的阻抗。有的膽石機就采用前面電壓放大用膽,末級功率放大用晶體管 。由於使用電晶體,體積可以縮細, 適合空間鬥士。

(圖為一部OTL耳擴膽機)

OPT, OTL 各有好處,有人覺得OTL冇咗火牛所以會有最完全膽味,亦有人覺得OPT個火牛係「膽味」主要來源。
膽amp 同其他amp 一樣都有分pre amp, power amp,通常headphone amp 就合埋一齊一部過,係2 channel 界,合埋一部就叫合拼機。
上面講個3種分類都係用輸出(aka 後級, power amp)作為條件,自然就冇講前級 pre amp 個part 係點。實際上pre amp 呢part 唔會再特別分(你都可以話都係class A, class AB; balance, unbalance 呢d,不過都唔係膽機特有分類)
當你見部機得一款膽,不論一對定單支,可以肯定係Hybrid 先。至於個膽係用於前級定後級就要再睇。
而點解得一支膽,因為個支膽分類係dual triode膽,即係一粒有兩個放大元件,咁就可以一粒膽做曬左右channel。同樣concept 係op amp chip 都搵到,有d amp 用一粒op amp, 有d要2粒或以上,因為op amp chip 都有分係唔係「單邊」。

延伸去講,既然有d膽amp 前級都用一對膽,點解冇balance output?
技術上的確可以咁係,balance 都係放大4個signal, 一對dual triode膽夠做。不過其實好多時用一對膽做前級係想每個channel 嘅+ve signal copy 一份做返個common mode rejection, 減低膽噪。所以實際上唔會用-ve input
如果要咁樣每個input signal 獨立自己做common mode rejection,真正全平衡嘅膽機要4支dual triode膽先得。所以bha 100 要4支膽。

究竟hqp用embedded(即係佢地出嘅linux)同Windows版會唔會分別好大
我9估windows 好聲d

啱啱收到fidelizer了,今晚再玩

巴打可唔可以比較下用同唔同fidelizer分別?我仲係免費仔
