重超音既音量調較問題,想請教ching們.
小弟有個問題想問,關於ching們接駁有源重低音後,個音量方面.
1.用amp+盡個sw既db.之後再調較sub仔既volume.
2.扭盡sub仔個volume,再用amp調較sw既db.
其實有冇分別,& ching 們你地會用邊個方案?
會唔會用第1個方案特別發揮到條靚既sub仔線呢?
定係其實冇分別.
望各ching指點一二~!
重超音既音量調較問題,想請教ching們.
下，扭盡咁嚴重 ？少心燒十仔份amp 喎- 發送自我的 iPhone 大板凳應用 `乜唔係..唔可以去咁盡咩!!!{:6_141:} 雖然我都係新手, 應該先看看你部Amp本manual, 我用Yamaha, manual有教, 對住本manual去set 十仔同Amp, 之後要做次Auto setup. 完成後通常十仔個level扭去一半再少dd, 例如正正一半係12點向上, 就向"減"的方向扭多一度, 即睇錶11點方向, 再check下個amp用autosetup係出緊幾多, 通常係好少, 大約係level既4份1至3份1到啦. 再load碟試聽. 在試聽時如果覺得唔滿意可以調高調低, 但問題係我唔知應該調個Amp既outptu還是扭十仔(我會調Amp), 兩者又有乜分別? 請指教! {:6_122:}

Ching 千奇吾好扭盡...實燒架...
- 發送自我的 iPhone 大板凳應用 用音壓計，唔駛估估下 凡事去得太盡
緣份定必早盡
本身自己都未試過係個amp度將個sw db set最高...唔敢咁樣試....真係怕燒左隻拾仔囉
都係第一次聽人講"重超音"......{:6_183:}
請問樓主係邊度鄉下架?中港澳都好似冇人咁叫....(都係八掛問下,唔好插我...) CHing, I have downloaded an Audyssey setup guide which teach how to setup the subwoofer when using Audyssey auto calibration.
Here are some extracts:
B. Disable the Low-Pass Filter (LPF) on the subwoofer, if allowed.
1. Disabling the Low-Pass-Filter (LPF) will result in more accurate subwoofer distance measurements.
2. If the LPF cannot be disabled, set it to the highest frequency allowed.
C. Ensure the subwoofer(s) are at least 3 – 5 inches (7 – 13 cm) from the wall.
1. Reverberating walls may result in inaccurate subwoofer distance measurements.
D. Set the subwoofer polarity (0 or 180 degrees), (+ or -) to “0” or “+”.
E. If the subwoofer has a phase control (in addition to the polarity control), set it at “0”.
1. Phase controls on subwoofers apply "delay" at one frequency rather than the needed group delay that is frequency-independent. So, it is best to just leave them at “0”.
F. If the sub has an EQ system, you can use it to tame large peaks (see item 1 below) before calibrating with Audyssey, but this is generally not recommended. Most of these EQ systems only allow one measurement position, and therefore only correct the amplitude (volume) for one seating position. Audyssey adds the benefit of measuring in the time domain for multiple seating positions to create an acoustic bubble.
Note 1 – Crossover Settings
Audyssey MultEQ measures in-room response of each speaker, determining the lowest the frequency they can reasonably produce. This is known as the -3dB frequency point. The -3dB frequency point is used by the receiver / processor to calculate the speaker settings (Large / Small) and set the crossover points, if applicable. The bass management system in the receiver / processor then performs the high and low pass filtering centered at the crossover frequency. The important point is that Audyssey does not set the crossovers. Unfortunately, current receiver / processor models do not display or report the -3dB frequency point measured for each speaker. The only information available is whether or not the speaker was designated “Large” or “Small”, and any crossover point selected.
After finishing the setup, you can change the subwoofer and amp's crossover frequency to whatever you want, say, 80Hz.
One more tips from the guide:
1. If you are using MultEQ or MultEQ XT you should use all six or eight measurement positions available.
I followed all instructions from the guide to setup my Onkyo 876 which turned out a very very smooth and good 3D surround effect. Worth to try follow it!! The subwoofer's bass has been naturally dissolved into the surround effect, and becomes more puchy and powerfull when you are watching the movie.
