Installation and debugging method of pan-sound FA audio

Buying a stereo may be a simple matter, but how to install and debug it is relatively difficult. How to install and configure the pan-sound FA sound system becomes particularly important for users who buy pan-sound. Here, we will make a detailed analysis of the installation and debugging of speakers in the general home environment, hoping to give consumers a guide.

Sound system is a very important part of home theater and karaoke. In addition to good visual effects, the sense of sound encirclement and accurate audio-visual positioning are the most important. Therefore, after choosing the FA series products suitable for you in the process of building a home theater, the next work is the erection, installation and debugging of the speakers. Because the home theater system has a set of strict specifications in the installation, positioning and debugging of speakers, that is to say, users can only get ideal sound if they install and debug speakers according to these specifications. In fact, some related installation steps and debugging methods of pan-sound FA home theater speakers have been mentioned in previous articles, but they may only be described in a special environment and may not be applicable to other home environments.

Installation of front speaker:

The front channel consists of two main speakers and a center speaker, which is called LCR channel for short. These three speakers need to be responsible for most of the sound in the software. Therefore, it is very important in the installation process. According to the example of THX, the best installation method of LCR speakers is to install three speakers at the same height, which is flush with the ear height when the listener sits down, so as to obtain the best sound field and correct vocal dialogue positioning. However, for the vast majority of consumers, the family environment does not necessarily have such conditions. For example, consumers who don't use sound screens or televisions can't install them in this way. For these consumers, we can try to install the center speaker on the upper or lower edge of the display device, and then adjust the radiation direction of the speaker. However, we must pay attention to this method, that is, the angle between the installation height of the center speaker and the left and right channel speakers cannot be 10 degrees, so as not to destroy the audio-visual positioning and sound field of human voice dialogue.

In addition to the above installation methods, users can also try to install LCR speakers on the upper edge or the lower edge of the display device at the same time. Then, the radiation directions of the three speakers are adjusted in the same way, so that the ideal front sound field can also be obtained.

Installation and debugging method of pan-sound FA sound.

Install surround speaker:

At present, regarding surround speakers, pan-sound FA audio includes master series dipole radiation speakers and direct speakers of Tomahawk, Elf series and CI customized series. For example, for a 5. 1 channel sound system, you need to use 2 surround speakers. There are also some specific requirements when installing these speakers. For example, the direct speaker, like the front LCR channel, points the radiation direction to the listening position and places it between 90 ~110 on both sides of the listener. For dipole speakers, it is necessary to point the "zero zone" of the speaker to the listening position. In terms of the installation height of the speaker, taking THX as an example, the installation height is 0.6 meters or more higher than the listener's head, so consumers need to use the speaker bracket to fix the speaker on the wall or hang it on the wall. Consumers can install speakers according to the speaker bracket or wall hanging provided by the original factory. If it is a 7. 1 channel sound system, put two extra rear surround sounds behind the viewing area and point the radiation direction to the listening position, with the same height as above.

Setting and placing of subwoofer;

The subwoofer is mainly used to make up for the shortage of the lower limit of the main speaker, and it can also increase the low-frequency energy. Therefore, consumers must set the low frequency division point of the processor in CS-700 power amplifier or CI customized series before using it. When setting the intersection, you should set it according to the speaker you choose. For example, if the overtone CK- 12 is selected, then all the crossover points can be set at 80-90 Hz. Considering the ambient sound field, the frequency division point of each channel must be set according to the low frequency response of each speaker. After setting the intersection, you can set up the subwoofer. So where is the subwoofer suitable for the room? Theoretically, the subwoofer can be placed anywhere in the room because the low frequency below 80Hz has almost no directionality. But in fact, consumers need to try to put the subwoofer in different positions of the room for audition in order to find out the best placement point. Generally speaking, consumers can put the subwoofer on the ground in front.

General debugging of loudspeaker system:

Finally, talk about the overall debugging of the speaker system, because the power amplifier of the pan-sound FA audio supports the independent adjustment of the volume of each speaker's movie mode and singing K mode, and displays the volume value, which can intuitively adjust the appropriate unified volume; Then, according to different acoustic environments, the EQ of two different modes, speaker cinema and K song, are adjusted, and then the speaker settings are basically completed.
