What's wrong with the weather forecast suddenly appearing on the stereo?
The audio transmission feeder of the stereo is also an antenna to some extent. In addition, high-frequency signals will be connected in series in the power grid, separated by the detection of electronic circuits, and the broadcast sound can be heard in the speaker after amplification.
Replace the feeder, increase the high-frequency filtering of the input signal, or increase the filtering at the power supply end ... all these should be analyzed in detail before deciding how to implement it.
Before choosing a stereo, you must do your homework and listen to other people's suggestions. Here I can simply tell you that hivi and landscape need to be told to you first. Many friends told me that hivi is difficult to push when it is actually used, and it is difficult to push the amplifier well because of its large investment. If you are an enthusiast, there will be no problem. At present, the reputation of landscape brands is not very good, so it is not recommended to pay attention to brands. Don't consider the low-end landscape, and the high-end one doesn't need to consider the brand. Let me tell you about BT- audio AB HIFI suit. AB bookcase is a HIFI box with excellent comprehensive performance, which reproduces the classic and pure English sound. Adopt super instantaneous response unit, the high tone is durable, the low tone is not sticky, the strong tone is not dry, and the weak tone is not empty. The warm and mellow timbre shows the infinite charm of music, and you can feel the charming melody of British legend, appreciate the pedigree, sound quality and workmanship.
The style contained in AB bookcase comes from the unique design of BT-audio audio engineer, a desktop HIFI speaker with bedroom and study, with exquisite and elegant appearance. First-class workmanship and sound quality have created the myth of high-end and low price in the audio industry, and completely brought the concept of parity to the extreme!
I hope the answer can help you.
