乜原來真係會多4dB!

chanwt

用了威記800 Ultra, 一直都疑惑於 "左"定"右", 單插定双插。
買線的sales always said "一開二" or "一開二" 都一樣, 任你揀。
試過幾問shop都係咁講, 信以為真。

真至最近買了過sound level meter, 先試單插至"L" 較至84dB "slow and c" -- 用 test sound
再用一開二插amp 的LFE, 用兩條線插Sub woofer 的Ｌ+Ｒ, 再度, 完全冇較嘢,竟然有88dB..

really surprise to have the difference!

點解d sales 成日話無方別呢???
因為無一出二的sub woofer cable, 不知会不会一樣結果??
各位Ching, C弟, 記得買一出二 cable 啦!

chanwt 兄

你睇下說明書睇下有無說明要插R/L定插晒

其實多左4dB係咪真係=好左? 如果你要多4dB,不如扭高個Gain啦,又唔洗錢~ 如果之前set好晒咪要o係個amp度set番細? 潛得低o左就話者.
大家討論下, 不喜勿插~

Instruction did not mention in a definite answer, It just said if one inout is to be used, use the "Left" one. My question is not about "left" or "right" .. Not this thread!

wm07 兄, 問得好,我也不知道 "多左4dB係咪真係=好左?"  或許其他c HING 可以賜教!
我只係奇怪為什麽those shop keeper alway said " no difference" for 1 出1 or 1出2...

量多了, 但質又如何?

kleehkg兄，我現在都用緊哩隻十仔，我都用o左一出二分插，是大聲o左，但後來我轉番直插入Left input，再用Amp auto cal一次，再加大番sub channel 至0db，效果和之前一樣。另外，各位師常常說調較Gain的音量是只那一個位置呢？請賜教一o下小弟。

Gain = 你subwoofer的volume control
