Tell me your Z7 output level to me. It is describe in the Z7 manual. I own Z11. But may not be the same.
UCD180 power should >> than internal Z7. But you may need to add buffer amp at input stage if gain is not enough.
You can use following config.
1. Front L/R --> UCD400 x 4
2. Center --> UCD400 X 1
3. Rear surround --> Default Z7.
4. Presense speaker --> Default Z7.
If you are using Water Goods of Z7, all problem will solve....
我想行9CH,所以要決定的是:如果9CH其中5CH用上UCD,LCR3個CH是定會用上UCD的
// Yes, Front L,R,C should use UCD400.
問題就是上前置跟後中置這2組是不能同時用Z7後級推動,其中一方一定要用上後級.........
// You must install Presence speaker.....Very good performance.
要是後中置用上後級,又怕同後置不夾,而且我覺得後置比後中置更加重要,後置也沒用上,後中置更沒這個需要
// Rear Surround or Surround?
// Z12 will have 後中置, coming at Dec-2010. 8 HDMI input... Cannot disclose too much....
要是上前置用上,因為本人覺得上前輸出太少,z7已勝任有餘,怕浪費了ucd
而且本身上前輸出就不太,LR=0db,上前也要調整到5db方見效果要是再用上ucd180就真是........
太多問題,我想還是買了ucd400,看差多少,再看用途
// You may need to increase the input gain, some circuit modify in UCD400.
kk sir
你用z11加了ucd之後分別大嗎?

UCD是不是可以透過以下幾點提升質素
更換UCD上的電容
更換/加大ST穩壓上的電容
幫OPAMP加獨立+-12V穩壓
以上幾點正確嗎???還有什麼方法可以提升UCD質素???
