Explain why you bought this item first, so as not to let the gods understand why I didn't spend this money on xxx.
New home decoration, according to my own idea, the living room to install projection, which involves the increase of living room equipment and pre-embedded lines. I originally planned to configure 5.1 speakers + amplifiers, but this project was strongly opposed by my wife. The first reason was that the distribution of 5+1 speakers seriously affected the neatness of the walls (a few satellites appeared on the American style wall). The box is indeed ugly, that is, the use of column speakers is the same), the second is the problem of money, the embedded line will increase the investment in hydropower reform, and 5.1 speakers + amplifier configuration also how about 4,000 or so
This is what she strongly disagrees with (she thinks that the 2500 budget is up to earth). From the perspective of family harmony, we can only take a second place and begin to look at the various whispering walls, and because of the switching of televisions, projections, PS4s, set-top boxes, etc., if you do not buy amps, you must choose to bring HDMI. The whispering wall of the input/output function makes this selection even smaller. This is a lot better than Sony's sound-quality whispering walls, and there are many whispering whispering walls that are cheaper than it is, but it's not much to meet the switching requirements of equipment. I locked this CT780 together
, but it has been around 3200 prices is also an important factor hindering my start, fortunately, around 5.1 Jingdong activities, to buy the goods and a small whale 55pro color TV at less than 6500 price (this later come to cheat gold coins)
Next, take this echo wall out of the box
The package clearly states its features, in addition to the transfer function I need, there are Bluetooth and nfc links, external subwoofer, 2.1-channel audio 5.1 can be virtual, support for mobile app control 
The whispering gallery itself is 1 meter long, 5CM high, with display function in the middle, can prompt the signal source and the volume level, on the side there is power, signal switching, volume +-4 switches
The interface on the back side forgot to shoot, borrow an official map, the left 3 HDMI interface, 1 and 2 are input), 3 with ARC function, direct support for audio back. In the middle is another HDMI input, as well as a fiber input and audio input 
Low-frequency gun has a dedicated power button, and there is a wireless connection button with the host to facilitate the subwoofer to be placed according to their needs
Subwoofer work can only be said in general, obvious particle board material shell, somewhat inconsistent with the "Dafa identity", the origin is Malaysia, it seems that the current manufacturing shift is really not a joke. Also reminded that the device can only work at altitudes below 2,000 meters, as well as working in non-tropical areas, reminds me of the first time I heard that when buying a refrigerator, home appliances also have a climate division.
This is other widgets, including manuals, remote controls, whispering stands, batteries, etc.
At the end, attach a photo of the fit and the initial photo of the function. The set-top box is connected to the whispering gallery, and the whispering gallery is connected to the projection. It successfully implements the functions that I need. After that, it tries to connect the TV and the whispering gallery, all of which are expected. As for the projection position, sound effects, etc., and then slowly adjust it after you stay, and then attach a detailed test.
