A, the consultation

1, we advocate make plan according to the scene, according to drawings and not only observe the actual scene, the smallpox horn type selection and layout of the horn equinoctial scheme in general it is difficult to achieve the ideal effect. Installation space between smallpox horn, inside the industry there is a reference: each of the distance between two speakers for the horn twice the distance to the ground, often this method can satisfy the full play of voice even, speakers are more waste, but need according to different venues environment to configure the speaker and the speaker power point layout, personnel in the need to consider the venue (listeners) often area location, listeners are often moving, or a fixed position, is, sitting or standing, the whole stadium environment factors such as the size of the background noise. Hotel, hotel, restaurant, room, hall, corridor, office, supermarket stores, exhibition hall and so on every venues and a local speaker installation is different, if you want to do, there is no copy of the standard, just like a good hairdresser, need according to each person's face, head shape, skin color, hair, and even personality, professional, and so on and so forth to design a hair style, from that point of view, even the simplest of smallpox horn design installation is not purely technical issues, a good background music project, is a combination of experience, technology and art.

2, about the horn, and other equipment selection problem, many companies will provide three schemes for your choice: poor, middle-grade, the best, or: cheap, in general, the most expensive, or someone said, homebred, joint venture and imported. Provide solution for customer to choose 3 class. Many customers are very satisfied to be able to get the choice of three class. This can be described as a service provides a very in place, but from our speaking, we think that this is irresponsible behavior, this is just a business behavior, and it's irresponsible behavior. I'll give you an example: did you go to the store hair, just like a perm, hair stylist in the store will come up with a something like some menu for you, and three levels to choose from: cheap, in general, yes, or 180 yuan, 280 yuan, 380 yuan, or normal potions, general potion, import potion. Hot heads has three options, and you don not clear hot for you a the head of the head of the 180 yuan and 280 yuan, what's the difference between, you ask him, he will certainly tell you 180 yuan only ordinary potions, but 280 yuan with good potions, good potions hot effect is good, and little damage to the hair, then you will, of course, according to the actual situation of your own choice. But the stylist will never tell you this: there is a certain damage to the hair marcel, the size of the damage and ironing out hair effect with your choice of 180, 280, 380, the potion of fundamental relations is not big, the key is ironing: in short, each person's hair is different, depending on the hair, how many potions, wash how long, how long it hot and hair stylist hand skills etc. These are decisions you iron out the hairstyle modelling of good or bad, the decision of the size of the damage to the hair phonemes. You have not experienced: spend 180 yuan can iron out a beautiful modelling, or rather spend 380 yuan hair be scorched away?

, of course, any kind of product will have different prices of a few class, have a good quality, low quality, even false and inferior product. I said this is not to say that have a good technology, even use the poor quality of the horn, can also play the beautiful music, it is impossible, I say is, we need to design the background music program to communicate with customers, to understand the status of the site, function, thus providing a set of according to the most reasonable compromise, not only provide three sets of different prices of solution to the customer choice, customers understand you, this technology is not much, besides, he also don't know what you said your horn and general and how the effect of the speaker to produce it. There are often such a situation: the customer chose a cheaper solution, but the whole project after installation, sound effect is very poor, can even hear the current sound inside, and the processing opinion is: cheap things in this way, can only achieve this effect. These are the irresponsible behavior.

Second, the installation process

Main said is cooperate to decorate the progress of the wiring installation process.

1, wiring, horn line layout with electrical wiring do best, but the speaker wire is low voltage, high voltage electrical work should follow (AC220V) don't be too close, to wear PVC tube, distance of 20 cm is ok, for installation and interference because of the factors, such as, do this, but the general line for the try to follow the route of high voltage or low voltage electrical layout, do not show mixed and disorderly, later maintenance is convenient, because the electrical wiring in general will leave access port, horn line should be different with other lines, not in the time of maintenance after don't know which one is the horn thread. Horn line of PVC pipe can be fixed on the ceiling steel hanger, it is also need with electrician to cooperate, the location of the horn point in the process of actual construction also need to consider all sorts of light position, the position of the fire sprinkler, air-conditioning outlet, and the shape of the ceiling cap, if your horn is installed with lamp repeat, or design in air-conditioning outlet, the total is not good, also affect beautiful.

Horn line wear PVC tube, we require PVC pipes do not use the elbow, but use, is the spring DaWan, ensure that the inside of the each pipe line from the junction box can be free to twitch, main is to ensure that maintenance and change line, thread later.

2 hole, horn the matters needing attention, the use of special open hole opener, don't damage the ceiling, especially the ceiling gesso condole top.

Hole diameter in accordance with the speaker of the size of the empty, in the actual construction, can be slightly a bit big, so to install and remove more easily, especially gypsum ceiling, horn installation is very tight, it is easy to destroy plasterboard to remove.

Smallpox horn opening: be careful not to drive to the longitudinal and transverse keel!

3, the installation of the smallpox horn, especially after finish paint, such as best careful installation, electrical installation at this time is usually a variety of light.

In all these processes need to cooperate well with the scene of the other type of work, not only for their own progress, always, learn to communicate with them.

Fourth, system debugging

Note that the system boot, check before running lines, of course, this work after the line decorated ceiling (sealing) should be test before the line again
