《 设置为大 还是设置为小 这不是问题 CC》不够专业的翻译

Echo33

前一段时间在论坛看了一个非常火的的帖子《设置为大还是设置为小这不是问题 CC》，原文为英文，自己水平有限，又不够专业，勉强翻译了一下。请大家指教。

Small and Large Speakers
In the bass management setup menu, setting speakers to"Small" and "Large" does not refer to the physical size ofyour speakers. It refers to the low frequency extension of your speakers orwhether your speakers are capable of reproducing powerful deep bass below 80 Hz.

在低音管理设置菜单，设置扬声器的“小”和“大”不是根据你扬声器的物理大小。它是指扬声器的低频延伸，或者您的扬声器能否再现80Hz以下强大的重低音的。

You should consultthe manual of your speakers or the Website of the manufacturer to getinformation about the frequency response of your speakers. The following tableis an approximation guideline as suggested by OutLaw Audio.

您应该参照一下扬声器的手册或制造商的网站，以了解你的音箱的频率响应的信息。下表是根据奥特洛音频建议而成的近似准则

  

扬声器尺寸/说明	交叉
具有一个10英寸或更大的低音喇叭的塔扬声器，或者具有两个8英寸或更大的低音喇叭的音箱	40Hz
具有一个8英寸或两个6英寸低音喇叭的小塔或大书架式音箱	60Hz
具有一个6英寸或两个5英寸低音喇叭的大书架式音箱	80Hz
具有一个5英寸或两个4英寸低音喇叭的大书架式音箱	100Hz
具有一个4英寸的低音喇叭（或更小）的卫星音箱	120Hz

Should I Set My Speakers to Large or Small?
People always ask this question. The answer is very simple. If you own asubwoofer that outputs good bass sound, you should set all your speakers toSMALL. In general, if you own a subwoofer, it may be wise to set all yourspeakers to small for several reasons:
When there is an overlap of bass sound from the front speakers and thesubwoofer, you will get bloated and boomy bass.

那我应该将扬声器设置为大还是小？
人们总是问这个问题。答案是非常简单的。一般情况下，如果你拥有一个低音炮，所有的扬声器设置成小的是明智的，有以下几个原因：如果前置扬声器和低音炮的低音重叠，你会听到臃肿，嗡嗡的低音。

A subwoofer can play low frequencies all the way down to 20Hz or lower. Evenrelatively large front speakers cannot go that low.
The placement of a sub in a room is the primary factor in receiving good basssound. You cannot adjust the position of the front speakers and move them tothe side or back.
If the subwoofer and the front speakers play the same bass frequencies, therewill be a possibility of phase cancellation of certain bass frequencies.

低音炮可以播放低频一路下跌到20HZ或者更低。但即使是比较大的前置扬声器也达不到这个程度。

副音箱在房间里的位置是接受良好的低音音效的首要因素。不要随意调整前置扬声器的位置，把它们移动到侧面或背面。

如果重低音扬声器与前置扬声器播放相同的低音频率，会有一定可能性出现低音频率相位抵消。

Redirecting the bass to the subwoofer relieves the receiver/amplifier fromhaving to work on reproducing the low frequencies and this greatly improves theheadroom.
If you are using the Audyssey MultEQ calibration, you will get much better bassperformance because the MultEQ subwoofer filters have 8x higher resolution thanthe filters for the other speakers.

重定向低音到低音炮减轻了接收器/放大器必须对再现低频段工作的轻度，这大大提高了净空高度。

如果您正在使用Audyssey MultEQ来校准，你会因为低音炮的MultEQ滤波器具有是其他音箱过滤器8倍以上的分辨率而得到更好的低音效果。

People have a psycological difficulty with the word SMALL. They have spent goodmoney on their front speakers and get insulted when the AVR sets them to SMALL.Remember that this is not a personal insult against you or your speakers. MyDefinitive Technology front speakers have 15" built-in subwoofers withbuilt-in 300 watt amplifiers. In addition to those, I have six externalsubwoofers in my HT room. When I set the front speakers to SMALL, the quality ofthe sound (both music and movies) improves.

有的人在心理很不情愿用“小”这个字眼。他们的前置扬声器好了大价钱，当他们的AVR设置为“小”时，他们会感到这是侮辱。请记住，这不是针对你个人或你的音箱的侮辱。我的权威技术前置扬声器有15个“内置低音炮带内置300瓦特放大器”。除了这些，在我的HT的房间还有有六个外部低音炮。当我设置了前置音箱为小，声音的质量（音乐和电影）得到了提高。

It is helpful to redefine the words SMALL and LARGE to:

LARGE= The speakers are not Bass Managed.
SMALL = The speakers are Bass Managed.

它是有助于重新定义大和小︰
                大 = 扬声器没有低音管理。

      小 = 扬声器有低音管理。

Double Bass or LFE+Main:
Manufacturers have different names forthis option.

Double BassOn (Onkyo) = LFE + Main (Denon) = Both (Yamaha)

双低音或 LFE + 主︰
在以下产品中，厂家有不同的名字。
双低音（安桥） = LFE + 主（天龙） = 两者（雅马哈）


When you use these options, Bassmanagement becomes enabled for Large (Full Band) speakers. The frequency belowwhich the signals from the main speakers are sent to the subwoofer is set automaticallyin the Onkyo or can be changed to any number you like in Denon'simplementation. Onkyo and Denon use Audyssey and this information is verifiedby Audyssey.

当你使用以上产品，低音管理可以被应用到大（全波段）扬声器。在安桥设置中，主扬声器的信号被发送到低音炮的频率可以设置为自动，或者可以在天龙改为你喜欢的任何数字。安桥和天龙使用Audyssey，并且由Audyssey来验证这个信息

Double Bass or LFE+Main is an optionthat was created by AVR makers as a compromise to customers who were personally“offended” when their speakers were designated Small in the AVR's menu. In suchmodes, the mains run full-range AND the subwoofer is low passed at a specifiedfrequency. So both the main speakers and the subwoofer are receiving basssignals. The problem is that in the overlap frequency region between the suband the front speakers, the bass frequencies are doubled and tend to becomebloated and boomy.

低音提琴或 LFE + Main是由 AVR 制造商给客户的一种妥协，这些客户对他们扬声器的AVR 菜单中被设置了“变小”这个选项时感到生气。在这种模式下，在电源运行的全范围，低音炮可以在特定低频率通过。因此，无论音箱，还是低音炮都接收低音信号。而问题在于，在副音箱和前置扬声器之间的重叠的频率区域中，低音频率被加倍并且变得臃肿和充满嗡嗡声。

One of the most important factors inreceiving good bass sound in a small HT room is placement of the low frequencysources. Although the subwoofer can be moved around the room in order to findthe optimum position, the front speakers cannot be moved to other spots in theroom. In addition, when the bass frequencies are directed to both the frontspeakers and the subwoofer, there may be some phase cancellation problem forsome of these frequencies.

在一个小的HT房间，收到较好的低音音效的最重要因素是低频源的位置。虽然低音炮可以在房间里移动，而找到最佳的位置，前置扬声器却不能移动到房间内的其他地方。另外，当低音频率取决于前置扬声器和低音炮共同设置时，有可能出现对某些频率的相位抵消的问题。

Using a separate subwoofer and sendingall bass frequencies to it is beneficial. The proper way of distributing thebass sound across the room correctly is with more than one subwoofer. An evennumber of subwoofers, 2 or 4, is preferred.

使用一个单独的低音炮以及用它发送所有的低音频率是有好处的。正确的方法是用有多个低音炮让低音能够正确地穿过房间。偶数低音炮是首选，通常2 个或4个。

Bass Management inMulti-Channel Systems
In a modern 5.1 system, the signals fromthe five speakers are sent through a high pass filter so that only frequenciesabove the cutoff frequency are sent to the corresponding speakers. At the sametime, a lowpass filter redirects frequencies below the cutoff frequency fromeach channel to the subwoofer. Meanwhile, the LFE passes through its ownbuilt-in lowpass filter (this frequency does not depend on the low passfrequency between the main loudspeakers and the subwoofer) and are passed tothe subwoofer. The low frequencies of all other channels are summed togetherwith the LFE channel and sent to the subwoofer. Different receivers performbass management differently. The following diagrams demonstrate differentoptions for Bass Management when speakers are set to "Large" or"Small". Although many newAVR's follow the bass management depicted in the first diagram, it is importantto be aware of the other alternatives.

低音管理多通道系统

在现代5.1系统中，来自五个扬声器的信号通过一个高通滤波器被发送，以便只有在截止频率以上的频率才能被发送到相应的扬声器。同时，一个低通滤波器把每个通道到低音炮的音频重定向到截止频率之下。同时，LFE穿过其自身内置的低通滤波器（该频率不依赖于低通频率的主扬声器和低音炮），并传递到低音炮。所有其他通道的低频与LFE声道一起相加，发送到低音炮。不同的接收机进行不同的低音管理。下面的图表演示了党扬声器被设置为“大”或“小”时，低音管理的不同选项。虽然许多新的AVR按照第一图中所描绘的低音管理，但知道其他的设置是非常重要的。

SPEAKER ANDSUBWOOFER SETUP

扬声器和低音炮安装程序

Subwoofer Setupand Crossover Settings:

1.   You need a realtively long (12ft or longer) sub cable toexperiment with the position of the sub in the room. Get a long RG6 subwoofercable from Monoprice.com or any other source. RG6 cables with RCA connectors atboth ends have good shielding and work better than regular RCA cables.

2.   You may also need a Y adapter (2 male, 1 female).

低音炮设置和交叉设置：

1.你需要一个较长的（12英尺或者更长）的音箱线缆对房间里副音箱的位置进行试验。从Monoprice.com或其他途径得到一条长的RG6低音炮电缆。两端带有RCA连接器的RG6电缆具有良好的屏蔽功能，性能也比普通RCA电缆更好。

2.您可能还需要一个Y型适配器（2公，1母）。

3.   Connect one end of the sub cable to LFE out (sub out orsub pre-out) on the back of the receiver.

4.   Connect the other end of the sub cable to the Leftchannel input (on some subs, the Right channel can also work) of the subwoofer.If you use a Y adapter (2 male, 1 female) and connect the subwoofer cable toboth the Left and Right inputs on the back of the sub, you may get between 3dbto 6db more output from the subwoofer. Refer to the footnote.

3. 将副音箱电缆的一端连接到到接收器的背面的LFE输出（SUB 输出或音箱前置输出）。

4. 将副音箱电缆的另一端连接到低音炮的左声道输入（在某些潜艇，右声道的也可以工作）。如果您使用Y适配器（2公1母），并且将低音炮电缆连接到副音箱背面的左声道输入和右声道输入的时候，你可能从低音炮里得到多输出的3分到6分贝的重低音。请参阅脚注。

5.   Turn the sub to on and set it to Auto.

6.   On the back of the sub, turn the crossover all the way upto the maximum level or turn it off. You set the crossovers in the receiver'smenu.

5.打开副音箱，并将其设置为自动。

6.在副音箱的后面，把交叉一路开到最高水平，或者将其关闭。你可以设置在接收器菜单中的交叉。

7.   On the back of the sub, turn the level (gain) to 50%-65%.You can adjust that a little later during calibration. However, it is a goodidea not to exceed the 3/4 (75%) point.

8.   In the receiver's menu, make sure the subwoofer is turnedto ON.

7.在副音箱的背面，转动电平（增益）到50％-65％。在校准期间，你可以调整得稍晚些。然而，最好不要超过3/4（75％）。

8.在接收器的菜单中，确保低音炮处于打开状态。

9.   In the receiver's menu, set all the speakers to SMALL.

10.  In the receiver'smenu, set the high pass filter (HPF) crossover frequencies of all your speakersto at least 10Hz or 15Hz above the minimum frequency extension of the speakers.If you can't find the frequency response of your speakers, consult the table atthe beginning of this thread.

9.在接收机的菜单中，将所有的发声器者设置为小。

10.在接收器的菜单中，将所有扬声器的高通滤波器（HPF）交叉频率设置为至少10Hz或最低频率15Hz以上的延伸范围。如果你找不到音箱的频率响应，请查阅此线程初表。

11.  In the receiver'smenu, set the low pass filter (LPF) of the subwoofer to 120Hz.

12.  If your receiverdoes not allow you to set the crossovers of the individual speakers, set the(HPF/LPF) crossover to somewhere between 80Hz to 120Hz according to the lowfrequency extension of your speakers. If you can't find your speakers frequencyresponse, consult the table at the beginning of this thread.

11.在接收器的菜单中，将低音炮的的低通滤波器（LPF）到120Hz。

12.如果你的接收机不允许你设置各个扬声器的交叉，根据扬声器的低频延伸，在（HPF / LPF）交叉的地方为设置为80Hz到120Hz之间。如果你找不到你的音箱的频率响应，请参阅此线程初表。

13.  In the receiver'smenu, set the subwoofer to LFE and not LFE+Main or Double Bass.

14.  Run thecalibration program. The Audyssey calibration program works best if you run itfor multiple listening positions.

13.在接收器的菜单中，设置低音炮为LFE，而不是设置为LFE +Main或低音提琴。

14.运行校准程序。如果你用多个聆听位置来运行，Audyssey校准程序的效果最好。

15.  If the calibrationprogram changes the above settings, you can change them manually to abovevalues. In general, increasing the crossover is ok. If you lower the crossoverbelow the level that Audyssey calibration has set, Auddyssey will not apply itsfilters to those lower frequencies below the crossover point.

15.如果校准程序更改上面的设置，您可以手动更改它们为上述值。一般情况下，增加交叉就可以。如果你的交叉设置得低于Audyssey校准设置的水平交叉，Auddyssey 将不适用于其筛选器下面的交叉点处的那些较低的频率。

Note: The phase control on the back thesubwoofers is a usually a simplistic analog control that only changes the phaseat one frequency. Proper phase alignment requires that the phase change isdifferent at every frequency. Unfortunately, that is not possible with ananalog control. As a result, Audysseyrecommends that you leave the phase control at zero

注：背面的低音炮的相位控制是一个通常是一个简单的模拟量控制，即只有一个频率的相位改变。正确的相位对准要求的相位变化是在每一频率都不同。不幸的是，这是不可能的模拟控制。其结果是，Audyssey建议在零时离开相位控制。

Standard Low PassCutoff Frequency
An extensive survey conducted in Europeshowed that 80Hz is the best choice for receivers with fixed-frequency filters.The mean frequency that the vast majority of humans began to distinguishsubwoofer directionality was 185 Hz, and 80 Hz was the minimum frequency belowwhich no one heard directionality.

低通截止频率标准

在欧洲进行的广泛调查显示，80赫兹是具有固定频率滤波器接收机的最佳选择。绝大多数的人类开始能辨别出低音炮方向性的平均频率 185 Hz，80 Hz 以下是没有人辨别出方向性的最低频率。

There really isn't a standard low passcutoff frequency that applies to all situations. The THX suggestion to use 80Hzapplies only to THX CertifiedSpeakers. These speakersare required to have low frequency extension down to 80Hz. It is not a blindrecommendation that applies to all speakers. It doesn't make much sense to setthe HPF to 80Hz, for example, if the other speakers are small satellites andtheir frequency response do not go below 100Hz. Even though bass frequenciesabove 100Hz may become directional, a higher high pass filter such as 120Hz maybe required.

是不是真的有一个适用于所有情况的一个标准的低通截止频率。使用80Hz的THX的建议仅适用于THX认证的扬声器。这些扬声器需要有到 80 赫兹的低频延伸。这不是盲目的建议，而是适用于所有扬声器。没理由要将 HPF 设置为 80 Hz，举个例子，如果有其他音箱是小卫星音箱，并且他们的频率响应不应该低于 100 赫兹。尽管 100 赫兹以上的低音频率可能成为定向，一个更高的高通滤波器（例如 120 赫兹）可能会被需要。

Connecting andSetting Up Two Subwoofers:

1.   To add a second subwoofer, buy a Y adapter (1 male, 2female) and two sub cables. Insert the male side of the Y adapter into the LFEout (sub out or sub pre-out) on the back of the receiver. Attach the two subcables to the female sides of the Y adapter and connect each cable to the backof each subwoofer.

2.   With two subs, you will have to experiment to get goodbass sound. The end result will be better than one subwoofer as you can createmore uniform bass across the room for all listening positions.

   

连接并设置两个超低音炮：

1.添加第二个低音炮，需要买一个Y型适配器（1公，2母）和两个音箱电缆。插入Y形适配器的公端到接收机背面的LFE输出端（音箱输出或者前置输出）。将两个音箱电缆连接到Y形适配器的母端，将每根电缆连接到每个低音炮的背面。

2.有两个副音箱，你将不得不实验，以获得好的低音音效。最终的结果会比一个重低音扬声器要好，因为你可以为所有的聆听位置在整个房间创建更均匀的低音。

3.   Remember that our ears are not as sensitive to very lowfrequency sound. As a result, deeper and lower frequency bass sound does notsound as loud as upper frequency bass sound. A subwoofer that does not go aslow may sound louder, but it lacks the low frequency extension. It is possiblethat you are used to that from your previous subwoofer and your brain needssome time to adjust.

4.   If you are planning to use two subwoofers, you mustcarefully match their levels at your primary listening position. You may haveto turn one off and adjust the other one until you get it right.

3.请记住，我们的耳朵对非常低频率的声音不够敏感。因此，深入和较低频率的低音听起来并不比更高频率的低音响亮。没有去尽可能低的像重低音听起来响亮，但它缺乏的低频延伸。这可能是你习惯了以前的低音炮，你的大脑需要一定的时间来调整。

4.如果你计划使用两个低音炮，你必须在你主要的听音位置仔细地调整它们的水平。你可能必须关闭一个去调整另一个，直到你得到正确的。

5.   Also when you run two subs, there is possibility of phasecancellation. You need to experiment with their position and phase.

6.   Once all the placements are finalized, don't forget tore-calibrate your speakers again as different subwoofers and differentplacements will interact differently with the room boundaries.

5.此外，当您运行两个副音箱，会有相位抵消的可能性。你需要对它们的位置和相位进行测试。

6.一旦所有的展示位置确定下来，不要忘记重新校正您的音箱，因为不同的展示位置将与房间边界互相影响。

Placement of twoSubwoofers:
You need to place the two subs properlyfor the best bass performance. You can try three options:

1.   Put one in the middle of the right wall and one in themiddle of the left wall.

2.   Put one in the middle of the front wall and one in themiddle of the rear wall.

3.   Put one sub in the front right corner and the other subin the front left corner.

4.   Put one in the front corner and the other in the cornerin the the rear of the room.

5.   If you have two different subs, put the larger sub withbetter lower frequency extension in the front corner and put the smaller subclose to your listening area. The sub up front will provide you with deeper andlower frequency bass and sub near you will provide you with upper frequencybass sound.

两个超低音扬声器的放置：

为了得到最佳低音表现，你需要正确放置两个音箱的。你可以尝试以下几种选择

1.将一个在右侧壁的中间，一个在左侧壁中间。

2.将一个在前壁的中间，一个在后壁的中间。

3.将一个副音箱放在的右侧前面的墙角，另一个他副音箱放在左侧前面的墙角。

4.将一个放在 房间前面的角落，另一个放在房间后面的角落。

5.如果你有两个不同的副音箱，把具有更好的低频延伸的较大的音箱放在房间前面的墙角，把小一点的音箱靠近你的听觉区域。音箱在前面会为您提供更深、更低的低音频率，靠近你的音箱将会为您提供更高频率的低音。

In all cases, move the subs at least afoot away from the walls and adjust their levels so that one does not overpowerthe other.

在所有的情况下，音箱距离墙壁至少一英尺，调整它们的水平，以便使其中一个不会压倒另一个。

Adjustment of TwoSubwoofers

1.   On the back of the subs, turn their levels to 50%-60%, nohigher than 75%.

2.   On the back of the subs, turn their crossovers all theway up to their maximum point. You set the crossover in the receiver.

3.   In the receiver's menu, set all speakers to SMALL.

两个低音炮的调整

1.在音箱的背面，把他们的水平调到50％-60％，不要高于75％。

2.在音箱的后面，将它们的交叉设置到最高点。您可以设置在接收器中设置交叉。

3.在接收器的菜单中，将所有音箱设置为“小”。

4.   In the receiver's menu, set the crossovers of all thespeakers to 80Hz. You can deviate from 80Hz depending on the low frequencyextension of your speakers. Make sure the crossover is always set at least10Hz-15Hz higher than the minimum frequency response (+-3dB) of your speakers.

5.   In the receiver's menu, set the crossover frequency ofthe LFE channel to 120Hz.

6.   In the receiver's menu, set the level of the subwoofersto zero.

4.在接收器的菜单中，将所有的音箱的交叉设置为80Hz。您可以根据音箱的低频延伸偏离偏离80Hz。确保交叉设置始终比你的音箱的最低频率响应（+-3dB）高至少10Hz-15Hz。

5.在接收器的菜单，设置LFE声道的交叉频率为120Hz。

6.在接收器的菜单，设置低音炮的水平为零。

7.   Turn off one subwoofer.

8.   Play the test tones through the subwoofer that is on andmeasure its response with an SPL meter. Adjust its level on its back (not thereceiver) so that you get approximately 73dB.

9.   Turn on the other subwoofer and turn off the previoussubwoofer.

7.关闭一个低音炮。

8. 通过低音炮播放来测试音调，并测量其与声压计的回应。在低音炮（而不是接收器）的后面调整它的水平，以便得到近似73分贝的音量。

9.打开另一个低音炮，关闭之前的低音炮。

10.  Run test tonesthrough it and adjust the level on its back so that you get approximately 73dB.

11.  Now, turn on bothsubwoofers and do not touch the levels on their back.

12.  After you adjustthe level of each subwoofer independetly, it is a good idea to run thecalibration program inside the receiver. In addition to checking the level ofthe combined output of both subwoofers, the receiver will also equalize them.Alternatively, you can use an external parametric equalizer.

10.通过它运行测试音，并调整在它的后面的水平，以便使你得到大约73分贝音量。

11.现在，打开两个低音炮，不要碰在它们的后面的水平。

12.当你独立地调整完每个低音炮的水平之后，最好去运行一下在接收机内部校准程序。除了检查这两个低音炮的组合输出的电平之外，接收器也会平衡它们。另外，您也可以使用外部的参数均衡器。

13.  Double check thesettings with your SPL meter. Run the test tones again and adjust the levels ofall the speakers. Make sure the SPL meter is held steady at a 45 degree angleat the primary listening position. Don't stand directly behind the SPL meter.Stand on the side. It is best for the SPL meter to be on a tripod.

14.  When the timecomes to adjust the subwoofers, move the SPL meter slightly to the right andslightly to the left and average the dB level that it registers.

Hopefully this willwork. If you move the subwoofers or move your listening position, don't besurprised if the level of the subwoofers change drastically.

13.再次用声压计检查你的设置。再次运行测试音，并调整所有扬声器的水平。确保声压计在在主聆听位置保持45度角。不要直接站在声压计的后面。站在一边。最好将声压计放在三脚架上。

14.在时机成熟时，调整低音炮，轻微移动声压计的平均分贝水平到右边，然后轻微移动到左边，记录下平均的分贝水平。

希望我的建议会产生效果。如果移动低音炮或者改变您的聆听位置，出现低音炮的水平急剧变化时，千万不要感到惊讶
