General family environment speaker installation and commissioning

                                                                                                                                        General family environment speaker  installation and commissioning
When consumers choose a good speaker for its own, the next task is to carry out positioning of the speakers, installation and commissioning and a series of work. As the home theater speaker system installation, positioning and debugging, and other aspects of a strictly regulated, which means that the user only to comply with these specifications for installation and commissioning of the speaker + to get good sound. In fact, the magazine in the past, this issue also mentioned some related home theater speaker setup and debugging methods, but there may be only for a particular environment for talks, not necessarily to fit other family environment. Therefore, in this month's special report, we will be for general family environment on the speaker for the installation and debugging - second introduction, I hope to give consumers a guide.

Installation of the front channel speaker

    Channel by the two main front speakers and a center speaker component, referred to as LCR channels. These three speakers are responsible for most of the voice software. Therefore, when installation is very important. According to THX example, LCR speaker is the best way to install three speakers installed on the same height, and with the listener's ear height when seated flush, so as to get the best sound and voice dialogue locate the right people . However, most consumers do not necessarily have a family environment for such conditions. For example, to use a slotted screen TV consumers or used in accordance with the above method can not be installed. For these consumers, the center speaker can try to install the display device along the upper edge or the next, and then on the radiation direction of the speaker. However, this point must be noted that the center speaker installation height and L, only channel speaker can not make a big angle between 10 degrees, so as not to damage the human voice and the dialogue of the sound image localization sound field.

    In addition to the installation method, the user can try to LCR channel speaker also installed in the display device along the upper edge or lower. Then, the radiation of the three speakers to adjust the direction of doing the same, this can also get an ideal sound field in front.

Surround speaker installation

    Surround speakers on the market now are the dipole radiation type speaker as well as traditional direct radiation enclosure. For the current 7.1-channel AV systems, you need to use the 4 surround speakers.

    An case, you can configure four dipole radiation type speaker or four direct radiation enclosure, or side of the channel with dipole-type speakers, rear channel speaker is the direct radiant. Installation of these speakers have some specific requirements. For example, the direct radiation speaker and as the front LCR channels will point to the listening position the radiation for the dipole-type speakers need to be speaker of the "zero zone" pointing to the listening position. The installation height of the speaker, according to THX example, the installed height of between about 1.8m-2.2m, this time consumers will need to use the speaker speaker bracket fixed to the wall. Therefore, consumers can go to Circuit City to buy some of the shops selling rack suitable speaker bracket to be installed on the speaker. If you can not find the right support, can be considered according to their speakers to be made one, but the cost would be relatively higher only. However, there are some speaker manufacturers in the production when the speaker will introduce its products under the corresponding speaker stand, used to facilitate the sale to consumers. Such as M & K, Genelec professional manufacturers have introduced the corresponding speaker accessories.

Subwoofer setting and display

    Subwoofer is primarily used to make up for the main speakers lack the low frequency limit set at the same time, it can also serve to increase the role of low-frequency energy. Therefore, consumers must be configured before use AV amplifier low-frequency crossover point. Set the crossover point in time, should you choose to set the speaker. For example, the choice is M & K, Atlanta, etc. are THX certified home theater speaker, then the crossover point can be all set to 80Hz. As for the other speakers, you must be based on the low-frequency response of each speaker to set the crossover point for each channel. Crossover Frequency setting is completed, you can be on subwoofer positioning. Then the subwoofer placed in the room which place more suitable? As low frequency below 80Hz is almost non-directional, so in theory, free to place the subwoofer anywhere in the room. But in fact the consumers need to try super bass speakers in the room in a different location to audition to find the best placement of points results. As a general rule, consumers can be placed in front of the super bass speakers

The total speaker system debugging

    Finally talk about the overall speaker system debugging. First measurement of each speaker to the distance between the ear (generally tweeter to ear distance between subject) and the distance measurement value input to the AV amplifier. Then consumers listening position using sound pressure meter to measure sound pressure output of each channel, and which according to readings on the AV amplifier output of each channel independently, Tuen level adjustments, so that each channel of sound pressure to 80dB SPL reference. So basically complete the speaker settings. Upon the completion of the above two steps, in fact, common for large Hao points consumers have been regarded as a completion of the basic debugging. However, the pursuit of better results for some of the consumers, can recommend to use the equalizer on the room's frequency response curve for correction. Why is this open? Mainly because most of the existing consumer listening environment and not the ideal frequency response. Of course, some people feel more an equalizer will affect the sound quality, but if the room frequency response is not satisfactory, it will seriously affect the overall sound balance, finally led to the deterioration of the sound effects. Therefore, in the listening environment is relatively less ideal circumstances, the use of equalizer is a good choice. Before using the equalizer, the first condition is to understand their own room frequency response. At this time, you can find a friend in the acoustic measurement to help you measure the room's frequency response curve.

    Then, the room frequency response curve based on the EQ or gain for the corresponding decay. However, note that when adjusting the equalizer can not be over-adjustment is used. This is because the corresponding band equalizer to adjust the gain, actually increases the output of a frequency Tuen level, if a frequency adjustment of the excess gain, due to front-end amplifier will give in to excessive lead levels burn, so be careful when adjusting.

    Home theater speaker on the basic installation and set the general description has been completed. However, another thing to note is that consumers must make use of the software they are familiar with, and through their own sense of reality on the speaker system to listen to constant adjustment, so as to obtain satisfactory results
