A, wall hung extension: extension installation for Ming outfit, mainly through the extension of the screws on the base or a fixed installation back-plane of fixed and metope after installation extension. Wall hung extension convenient installation, but an extension itself more prominent metope, visual effect is not good. Because of its volume of the restrictions, internal can’t load many function module (some loading function modules is a simplified module);
B, embedded extension: extension installation for dark outfit, first the embedded bottom box extension bury a wall installation, again will be fixed in the bottom of the embedded extension on the box. After installation embedded extension with metope basic height consistent, for indoor whole visual effect is very good. Plus, because of embedded installation extension have larger space, can load more function expansion; Its shortcomings need for dark bury bottom box, construction difficult, and after the installation is not easy for mobile;
C, new products: super-thin wall hung extension: due to the above two and the advantages and disadvantages of the extension, such extension of traditional wall hung than average extension thin (the traditional wall hung by the receiver design, visual extension in part due to a black and white screen, so need compatible beyond metope altitude generally in more than 40 MM thickness, basic can’t then to reduce).
