請各位師兄提點
器材 Denon AVR 1709
Speakers MK 750 LCR
Woofer MK MX-250
Player Pioneer BD

早兩期HIFI音響話天龍唔夾MK,夾厚暖聲底喇叭

So ???? Can you help me THX !!!!!

唔會因為唔夾而人聲弱個喎，校得唔夠好姐，慢慢㴝啦，再唔掂先請高手出馬啦！

Denon 低 model 的通病/ 取向
之前用 2805 還可以
換了2309 一日, 中置失踪
立即換 2809 中置返來了
中置用Elac 2系
解決方法 1. 換高model(不是換中置, 可能不是中置問題)
2. 換AMP, onkyo中罝好些, 高低model亦然
3. 獨立調高中置音量

應該點Set呢 ???

make sure all speakers are level matched.

u need a spl meter to manually calibrate.

Buy a 音壓錶 and use the (Is it call )pink noise generated form the amplifier and let the 音壓錶 to help you to do the accurate measurement. Anyway,Is the speaker pointing towards you.
changing the amplifier may help but I guess Denon shouldn't be the bad.
You said "中置啲人聲好弱"? is that commonly in all the movies you played?

double check your center speaker all drivers are working, because it can be a blown tweeteror a mid/bass driver. sometimes a loose connnection may result reduced output.

各位師兄我已經用咗音壓錶啦,但都無戲院啲人聲咁實在同雄渾

all the movies i played

Is your center speaker firing directly towards the audience? It does make a difference.

Have you checked the high-pass crossover setting for the center channel? If your center speaker is small and the crossover is set too low, the lack of mid-bass may sound "weak".

If all else seems OK, it won't hurt to kick up the center level a dB or two.

i feel that the av amp power is not enough.
i used 2308 and 3007 now. that is a different world.
it cannot set up to solve

your center speaker is 80hz to 20khz. with your receiver set up try with setting speakers as small and crossover at 80hz or 100hz. regarding sub. make sure crossover set at maximum and volume level at about 9 to 10 o'clock. then calibrate the sub level with your spl meter. if other speakers have been calibrated at 75db then the sub should be about 72db as the spl meter is insensitive to low bass so the 72db as adjusted will be equivalent to 75db.

too hot subwoofer will overwhelm the dialogue from center speaker.

最新setting,cr120kz先可以有返人聲,但超低就過哂火!!!我係咪要係250隻十仔度校返80kz呢???唔該哂各位師兄

your subwoofer crossover should be set at maximum. this means your av receiver will take up the job and cross at 120hz.

if sub too hot u just turn down the volume control at the subwoofer. best at 9-10 o clock and also adjust the av receiver speaker settings so all speakers match sound level.

unless u are using satellite speakers 120hz is a bit high. thx standard is 80hz and if u are using small bookshelf speakers 100hz is very common. if u use refrigerator size speakers u may set at 50hz or 60hz. just a guideline.

"""250隻十仔度校返80kz呢"""

if u do this it means the bass from 80 to 120hz will disappear.

your av receiver will make a low pass of 120hz while your subwoofer will make a low pass of 80hz so the 80 to 120hz sound will be cut out.

i dont think u want this to happen.

可唔可以用中文解說呀?唔該cpu8088兄

好難set到完美呀,會唔會有啲師兄上門幫手set機呀???
