| [#9122] Accuphase Fans thanks, sunboy. But how do you know it equipped with remote in their spec. I searched out "remote" in following, but no luck. http://www.accuphase.com/cat/c-250en.pdf |

| [#9127] Accuphase Fans 經常聽大家談論damping factor 的數值;其實damping factor 究竟係乜東東?係米越大越好? |

| [#9128] Accuphase Fans linda0416 hing, Infomation about Damping Factor (copy from web) "放大器的Damping Factor 是基於本身的內阻抗和喇叭的阻抗(Ohm)亙相變化而產生的. Damping Factor 越大就表示放大器的輸出電阻越小. 它的作用是power amp的信號消失後控制喇叭單元錐體的活動能力, 以便能減少當訊息終止時錐體的餘震. 在理論上Power Amp的輸出阻抗是越小越好(如前級一樣)而Damping Factor是越大越好, 但亦不是一味追求大Damping的放大器才是正道!! 高Damping低Output 阻抗的放大器的成本高昂, 而且當Damping Factory高企時..喇叭的內電阻加大, 因而降低喇叭的瞬態響應. 對於我們一般玩家, 不須要在這些數據上來尋根究底, 這是專業電聲學的範疇, 不是三言兩語可以道明, 而且很多市面器材亦缺乏相關數據給我們參詳, 就算有亦未必是實據. 一切都要用儀器來測試為準, 這不是我們能力所及. 但兄的問題我可以給一個最低要求的指標. 晶體後級Min Damping Factor 是40, 而膽機是6. 有乜根據? 答案係...冇! 只是從一些從前看過的報導而說, TAS很早期已經有專題講述. Damping Factor 只是千萬種音響元素中的冰山一角, 兄不用過於費神, 亦無須以damping factor來作為配搭的主因. 在今天的聲學科枝上雖不至於百份百完美, 但出錯的機會已近乎零, 搭錯喇叭配錯機不會出現了." http://en.wikipedia.org/wiki/Damping_factor#Explanation |
