Written in the front, in 2014 acquired the largest fixed asset in life - house. Staying in a new house in 2015, I've been wondering how to make a sound in the new living room to see films and listen to music. Unfortunately, at that time, the house bought was a furbished room and lazy rewired, so the surround speakers were not pre-embedded and only some of the stereos with wireless function could be picked. Fortunately, our demand for sound effects is not high, LD's primary requirement is good-looking, followed by good. After searching the Internet for a long time, I finally decided to buy a Sony (SONY) BDV-N9200WL 3D Blu-ray wireless surround home theater.
The reason for choosing white is because the decoration color of our living room is also white, and white with atmosphere lights, the evening effect is still very dazzling. Another reason to choose this stereo is that the TV that we bought in our living room is also SONY, so it's a complete set, and it's easy to work together, and a remote control is all set. The television is a Sony (SONY) KDL-70W850B 70-inch full HD 3D LED LCD TV, which was purchased on November 11, 2014.

Four trays sit
Remove a big guy, subwoofer. It is much lighter than I thought and looks good, but the effect is not enough?
Next is the speaker and speaker stand, a total of four pairs and eight. Is divided into two parts, you need to assemble, a screwdriver to get
The main speaker came out, Tucao about, very light speaker
This is a connection plug, it is easy to distinguish the different colors, insert the central controller behind just fine, not wrong color is good, white small plug is the speaker atmosphere lamp led link, together inserted behind the central controller Ok
Ambient led lights behind the acoustic head
The speakers can also be wall-mounted, I did not pre-wire, there is a mounting hanger
Each speaker has a logo on the back of the speaker. For example, it surrounds the left side. When the time is right, the corresponding position will be displayed.
This big bag is a speaker stand used to connect the bottom tray and speaker body, it should be plastic, it is very light.
Speaker stand secured by screws and bottom tray
The black one is the fixed bottom tray, which is fixed and long.
After the bracket is installed, connect the main body of the speaker to the bracket. When connecting, you need to pay attention. Insert the speaker cable from the internal slot, put the cable under the bottom tray, and install all the effects.

Written in the end, the specific use of the situation just need to be familiar with, just wait a few days to test a variety of functions and then write the system's feelings and sound effects. Satisfied with the appearance, sony's big factory is still a good workmanship, whether it is white paint part or the middle of the metal paint part is perfect, set the speaker's body size is relatively small, easy to integrate into the living room's overall decoration . The most dazzling still is the ambient light, which will change with the color of the TV screen after it is turned on at night. Good-looking, dazzling is the evaluation of his appearance.

Application fields
Filter inductance is suitable for energy storage and filtering inductors in switching power supply, because of its high BS value and low loss.Compared with iron powder core and ferrite with the same volume and magnetic permeability, it has higher energy storage capacity. More widely used in AC inductors, output inductors, rotary transformers, pulse transformers, power factor positive circuits.
