ok, let me go to see see sin.

in user manual pg.41, make sure LFE is not OFF



pg.45, if u choose front spk is SMALL, then Sub will automatically set to YES, how abt yr system, it shows YES?





pg.47, crossover network, pls check the Freq is set to 100Hz or not, or I think u can set it to 80Hz.



u also can adjust the Sub volume to +db if u think the LFE not strong enough.



& make sure ......



just try this first, if it still can't work, try to reset all(since yr amp is 2nd hand, the 1st user might set it wrongly b/4)

終於攪好我跟ching提點重新比較之前setting同manual分別,原來係setting入面subwoofer設定為150Hz,之後改為80Hz.盡於OK啦!!
非常多謝幾位ching所比意見,我終於唔需要搬部機去葵涌修理(因為需要請假去實在太麻煩)
再次多謝幫忙!!

想請教一下點解150Hz同80Hz有何分別?怎麼情況subwoofer會用200Hz,150Hz,100Hz同80Hz???
