前方聲道音箱的安裝
Installation of front channel speaker
前方聲道由兩只主音箱和一只中置音箱組成,簡稱LCR聲道。這三只音箱需要負責軟件中大部分的聲音。因此,在安裝時顯得十分重要。根據THX的范例,LCR音箱的安裝方法是將三只音箱安裝在同一高度,并與收聽者坐下時的耳朵高度齊平,這樣才能獲得的音場以及正確的人聲對白定位。不過,對于絕大部分消費者的家庭環境來說并不一定具備這樣的條件。
The front channel consists of two main speakers and a middle speaker, which is called LCR channel for short. These three speakers are responsible for most of the sound in the software. Therefore, it is very important in the installation. According to the example of thx, the best way to install LCR speakers is to install three speakers at the same height, which is flush with the height of the listener's ears when sitting down, so as to obtain the best sound field and correct voice dialogue positioning. However, for the vast majority of consumers, the family environment does not necessarily have such conditions.
例如,沒有使用透聲幕或者使用電視機的消費者就不能按照以上的方法進行安裝了。對于這部分消費者來說,可以嘗試把中置音箱安裝在顯示設備的上沿或下沿,然后再對音箱的輻射方向進行調整。不過,這種做法有一點必須要注意,就是中置音箱的安裝高度與L、只聲道音箱之間的夾角不能大干10度,以免破壞人聲對白的聲像定位以及聲場。
For example, consumers who don't use sound screens or TV sets can't install them in the above way. For these consumers, we can try to install the center speaker on the top or bottom edge of the display device, and then adjust the radiation direction of the speaker. However, one thing we must pay attention to in this way is that the angle between the installation height of the center speaker and the L and only channel speakers should not be greater than 10 degrees, so as not to damage the audio-visual positioning and sound field of human voice dialogue.
除了上述的安裝方法外,用戶也可以嘗試將LCR聲道的音箱同時安裝在顯示設備的上沿或下沿。然后,再對三只音箱的輻射方向做相同的調整,這樣也可以獲得一個理想的前方聲場。
In addition to the above installation method, the user can also try to install the speaker of LCR channel on the top or bottom edge of the display device at the same time. Then, make the same adjustment to the radiation direction of the three speakers, so as to obtain an ideal front sound field.
環繞音箱的安裝
Installation of surround speaker
現時市面上銷售的環繞音箱有偶極輻射式音箱以及傳統的直接輻射式音箱。而對于現時7.1聲道AV系統來說,則需要使用4只環繞音箱。一股情況下,可以配置4只偶極輻射式音箱或者4只直接輻射式音箱,又或者側聲道采用偶極式音箱,后置聲道則采用直接輻射式音箱。這些音箱安裝時也有一些特定的要求。例如,直接輻射音箱與前方LCR聲道一樣將輻射方向指向聆聽位置,對于偶極式音箱則需要將音箱的“零區”指向聆聽位置。在音箱的安裝高度方面,根據THX的范例,安裝的高度大約在1.8m-2.2m之間,那么這時候消費者就需要利用音箱支架將音箱固定在墻面上。

At present, there are two types of surround speakers on the market: dipole radiation speakers and traditional direct radiation speakers. For the current 7.1-channel AV system, four surround speakers are required. In the case of one strand, four dipole radiation speakers or four direct radiation speakers can be configured, or dipole speakers can be used in the side channel and direct radiation speakers can be used in the rear channel. There are also some specific requirements for the installation of these speakers. For example, the direct radiation speaker points the radiation direction to the listening position just like the front LCR channel. For the dipole speaker, the "zero zone" of the speaker needs to be pointed to the listening position. In terms of the installation height of the speaker, according to the example of thx, the installation height is about 1.8m-2.2m. At this time, consumers need to use the speaker bracket to fix the speaker on the wall.
超低音音箱的設置與擺放
Setting and placing of subwoofer
超低音音箱主要是用來彌補主音箱的低頻下限不足而設的,同時,它還可以起到增加低頻能量的作用。所以,消費者在使用之前必須設定好AV放大器的低頻分頻點。而在設定分頻點時,應根據你所選擇的音箱進行設定。有THX認證的家庭影院音箱時,那么可將分頻點全部設定在80Hz。于其它音箱,你必須根據每只音箱的低頻響應來設定每個聲道的分頻點。分頻點設置完成后,就可以對超低音音箱進行擺位。那么超低音音箱擺在房間中哪個位置比較適合呢?由于80Hz以下的低頻幾乎是沒有方向性的,因此從理論上說,超低音音箱可以隨意放置在房間中任何一個地方。但實際上消費者需要嘗試將超低音音箱放在房間中不同的位置來試聽,以找出效果的放置點。而一般情況下,消費者可以將超低音音箱放置在前方。
Subwoofer is mainly used to make up for the low frequency lower limit of the main speaker. At the same time, it can also increase the low frequency energy. Therefore, consumers must set the low frequency divider of AV Amplifier before using it. When setting the frequency division point, it should be set according to the speaker you choose. When there is a thx certified home theater speaker, then all the frequency dividing points can be set at 80Hz. As for other speakers, you must set the frequency division point of each channel according to the low frequency response of each speaker. After the frequency division point is set, the subwoofer can be set. So which position of the subwoofer in the room is more suitable? Since the low frequency below 80Hz is almost non directional, theoretically speaking, the subwoofer can be placed anywhere in the room. But in fact, consumers need to try to put the subwoofer in different places in the room to try to find the best place. In general, consumers can place the subwoofer in the front.

音箱系統的總調試
General debugging of speaker system
說說音箱系統的整體調試。量度出每個音箱到人耳之間的距離(一般以高音單元到人耳之間的距離為準),并將測量的距離值輸入到AV放大器中。然后消費者在聆聽位置上利用聲壓計測量出每個聲道的輸出聲壓,并根據讀數對AV放大器里面各聲道的輸出屯平進行獨立的調整,讓每個聲道的聲壓達到80dB的參考聲壓值。那么音箱設置就基本完成。
Finally, talk about the overall debugging of the speaker system. First, measure the distance between each speaker and the human ear (generally the distance between the treble unit and the human ear shall prevail), and input the measured distance value into the AV Amplifier. Then consumers use the sound pressure meter to measure the output sound pressure of each channel in the listening position, and independently adjust the output level of each channel in the AV amplifier according to the reading, so that the sound pressure of each channel can reach the reference sound pressure value of 80dB. Then the speaker setting is basically completed.
當完成上述的兩個步驟后,其實對于大鄗分的普通消費者來說已經算得上是完成了基本的調試。但是對于部分追求更好效果的消費者來說,可以使用均衡器來對房間的頻響曲線作修正。為什么要這樣敞?主要是由于現時大部分消費者的聽音環境的頻響曲線并不太理想的。當然,也有人認為多加一個均衡器會對音質構成影響,但若是房間的頻響曲線不理想,將會嚴重影響到整體的聲音平衡度,導致整個聲音效果變差。所以,在聽音環境相對不太理想的情況下,使用均衡器是一個不錯的選擇。
After the completion of the above two steps, in fact, for the average consumer with big scores, it can be regarded as the completion of the basic debugging. But for some consumers who pursue better effect, we can recommend using equalizer to correct the frequency response curve of the room. Why are you doing this? The main reason is that the frequency response curve of the listening environment of most consumers is not ideal. Of course, some people think that adding one more equalizer will affect the sound quality, but if the frequency response curve of the room is not ideal, it will seriously affect the overall sound balance, and finally lead to the deterioration of the whole sound effect. Therefore, the use of equalizer is a good choice when the listening environment is not ideal.
在使用均衡器之前,首要條件是要了解自己房間的頻響曲線。這時候,你需要測量出房間的頻響曲線。然后,再根據房間頻響曲線在均衡器上作相應的衰減或增益。不過,需要注意的是在調整均衡器的時候不能過度凋整。這是因為調整均衡器中相應頻段的增益,實際上就是提高了某個頻率的輸出屯平,如果某個頻率調整了過多的增益,會令放大器因前端給于的電平過大而導致燒壞,所以在調節時要慎重。
Before using the equalizer, the first condition is to know the frequency response curve of your room. At this time, you need to measure the frequency response curve of the room. Then, according to the room frequency response curve, the corresponding attenuation or gain is made on the equalizer. However, it should be noted that the equalizer should not be over adjusted. This is because adjusting the gain of the corresponding frequency band in the equalizer actually increases the output level of a certain frequency. If too much gain is adjusted for a certain frequency, the amplifier will burn out due to the excessive level given by the front end, so we should be careful in the adjustment.
