The first half of the renovation of new homes, many soft-loaded appliances are looking at Aunt Zhang here, such as the late decoration is still watching F55 LCD TV and JBL CINEMA STV180 echo wall.
Although TV claimed to use dual independent speakers, Dolby decoding certification, but in the actual playback of the video inside the USB disk, some of the source sound is too small, large-scale sound also has no effect, so I wanted to add a speaker. Originally considered to buy a power amplifier, but unfortunately the renovation has been debt-laden, see the echo wall recommended here to start. Because this aspect of the channel interface has not been studied, nothing is understood, so when buying it did not pay attention to it, because this TV claims a lot of interfaces, there is always an interface to use it. But when the audio was bought back and used, it was dumbfounded. The LCD TV at home had SPDIF coaxial and HDMI output, but the whispering wall only had fiber and AUX analog input. Not at all. But fortunately, you can connect with Bluetooth, but it is estimated that the sound quality is damaged.
Baidu took a moment and found that the coaxial SPDIF output is a digital signal, while the whispering wall fiber input is a digital signal, there should be a tool to convert. Checked on Taobao, there are many similar products, after selection and parity, basically identified two products, one is a digital to analog signal (SPDIF coaxial output, AUX analog input), one is a digital to digital signal ( SPDIF coaxial output, OPTICAL fiber input). This kind of thing is not very expensive, one is about 100 yuan, a lot of brands on the network, but I feel basically are OEM, so according to their own preferences on it.
I always feel that the optical fiber Cable is easy to break, and the analog signal Converter's power interface is the micro USB interface that is usually available to mobile phones, so I chose an audio converter with digital to analog signals. Because there is no coaxial audio cable, I also bought a special one.
Baidu's knowledge of analog signals and digital signals was inserted and broadcast. It felt quite right, but it was not an authoritative source and it was for reference only.
The converter can't wait to get it back after it's bought back. After connecting it, it can be used (the sound output on the TV should be changed to RAW output). It's a time when I am proud, but I chose to watch the MP4 in my USB flash drive. When the MKV format is sourced, the speaker emits a lot of noise, and it is lost. Try it several times, but if you change to a rmvb format source, the sound is normal, so the first attempt ended in failure.
Had to try another alternative, but it was a bit worried and worried about failing again. A coaxial-to-optic digital audio converter was purchased, and the SPDIF coaxial output from the TV was passed through the converter and the fiber-optic cable was connected to the whispering gallery. This time I tried various film sources. This time it was normal. If I can't, I'm going to take a durian.
Comparison of the two converters, similar in size, are not large, are slightly rough on the workmanship, printing is somewhat fuzzy, outside the box are made late. Both are powered by a 5V USB interface.
The home TV background wall electrician designed the upper and lower rows of four slots, but only four five-hole power outlets, when the set-top box is used, they are full, TV, speakers and audio converter are two holes There is no place to charge the phone. Just as the electrician had set aside two positions on the wall, according to him, it was used to connect the audio cable, so it was covered with a blank panel. I opened it this time, because the buses are moving into this side, and there are so many threads inside that there is almost no space. I took my life and moved the rightmost five-hole Socket over. Then I installed a five-hole socket with a USB interface on the far right side. I changed the upper and lower rows. After I finished the change, I immediately left three outlets. Now basically meet the requirements, and then put some extra lines are wrapped around the TV support frame, from the outside, the overall appearance is much better.
Finally, thanks to Aunt Zhang, because a lot of things on the decoration are basically pushed from the side of Aunt Zhang's push to buy, or will basically come to the side to see how much the current price and the historical discount, and then look at the value of friends Our evaluation will basically have a new receipt. Simply put the house in good repair, always carefully bookkeeping, and the budget is basically within control. Renovation, but also encountered some annoying or regret things, but also let yourself from a little white to a little understanding of what little, can help others to give advice to people, is it right? Can write a decoration diary here, ah, ha ha! Finally, use the amount of the decoration and the end of the more than one hundred restaurant lights on the side of the Aunt!
