sub.w問題

ericbusmo

說明書:crossove:this control relates to the upper cut-off frequency reproduced by your sub-w(65hz).all frequencies above the set level will be cut off by 12 or 24 db/octave(high cut) and not reproduced.the level is primarily based on the lower cut-off frequency of the other loudspeaker in your system
volume:the vol control allows you to change the volof your sub-w andtherefore the intensity of the low bass reproduction (0db)  turning to the right increases the vol and turning to the left reduces the vol.use the vol control to customise the vol of the canton sub-w to match the other loudspeaker in your system.
sub-w後面有兩按鈕   crossover(hz)   65  70  80  95  110  130  150
                          vol(db)-80  -18  -12  -6  0  +6  +9
在設定自動音場前sub-w應鈕去邊個位(hz and db)

crossover(hz)　：如果前置喇叭細隻就先set 110 hz,
前置喇叭大隻（或座地)就set 80hz

vol(db) : 鈕去最細和最大數值嘅中間位就ｏｋ

調較好便可開始用av amp作自動音場測試和設定

vol(db)-80  -18  -12  -6  0  +6  +9即係我個中間值係幾多???

-71/2= -35到啦

設定自動音場後,LEF為-15db,正常嗎???

不能一概而論，但一般av amp都會係set負數，
我用denon就set -8db

ericbusmo

照師兄講sub-w 設-35db,110hz,自動音埸設定後,前中後置為150hz,LEF為100hz,係咪ok喇???
如這設定ok,即係幾多hz下交由sub-w付責??

sub-w 設-35db <<< 似乎誇張左D!
一般情況下,LCR 會 set 80-100Hz

佢意思係指woofer本身音量set -35db，(因佢提供話-35db就係佢woofer輸出音量嘅一半)
