Speaker Assignment




 

 This test verifies that the speaker channel assignments are correct for a 5.1-channel sound system (left output from the receiver is going to the left speaker, center output to the center speaker, etc.) and that the audio output is balanced. To perform the test, modified pink noise (a "hissing" sound or static) will emanate from each audio channel. As this test plays, confirm that the output you hear from each speaker corresponds to that speaker's graphic depicted on your television. If a discrepancy exists, fix the incorrect wiring and run this test again.
 

声音分配

 





 

Improper volume levels for each speaker is a common problem with home theater systems. In multi-channel sound systems, the sound level for each speaker must be properly set to ensure accurate soundtrack reproduction. In the making of a movie, hours are often spent in THX certified mixing rooms mixing the audio tracks to precise levels to add to the realism and enjoyment of the motion picture. If the levels are improperly set in your home system, the audio imaging will be incorrect, affecting the accurate reproduction of everything from dialog to sound effects to the music track.
 
  这项测试检验声音分配是否正确。比如左音箱是否接在左声道,或中置音箱是否接在中置声道此类音箱连线问题,或各声道音量是否平衡。粉红噪声测试信号(沙沙声)将逐一地在各个声道音箱中发出,确认发声的音箱和屏幕上提示的相对应。否则重新纠正音响的连线。

每个音箱的音量是否适合是家庭影院的常见问题。多声道系统中的每个声道音量都必须合适才可以正确再现电影声轨。在THX认证的混音室里,往往化很多时间来为画面配音,以增加画面的娱乐性和真实感,而这些配音都是基于很精准的音量的。如果你家庭影院音量设置不正确,那如音效,配乐,对白的回放都不会正确了。
 

In order to check for a balanced audio system, sit where you would normally enjoy your home theater system. Then, listen to the series of test tones and be sure that each sounds equal in volume. Please note that these tones are not for adjusting the volume level of each speaker. Instead, this test is solely an aid in identifying improper level settings. You should use your receiver's internal test tones to properly set each speaker's volume level. Only these internal tones should be used for critical adjustment of your system's volume level for each individual channel. If you have a THX certified home system, contact your certified Home THX dealer for alignment information for your particular system.
 
  为了测试各声道音量是否平衡,您应坐在通常观赏影碟时的位置。仔细聆听一系列音调,确认每个声道的音量相等。但注意这些信号不是用来调节个声道音量的,这只是用来帮助判断音量设置是否合适的。你应该用功放内部的测试信号来调整,只应用内部的测试信号用来调节每个声道音量的。如果你的家庭影院是THX认证的,从你的THX经销商处取得帮助。
 

NOTE: If you are evaluating a two-channel system, you are concerned with only the left and right channels. If you are using a Dolby Pro-Logic system, remember that there is no distinction between the left surround and right surround channels.

  注意:使用双声道系统,只要检验左右声道连接就可以。使用Dolby Pro-Logic 系统时左右环绕音箱是没有区别的。
