The weather forecast suddenly appeared on the stereo. This kind of broadcast is very loud.

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.

When choosing a stereo, we should also consider the overall collocation between the appearance of the stereo and the living environment. The configuration of home theater should be based on the unified hobbies of family members, room area (watching movies, listening to music and singing) and economic situation. For example, when choosing, you can compare with each other. For example, hivi and Dana can talk about it first. Many friends told me that hivi is difficult to push when it is actually used, and the power amplifier is expensive and difficult to push. Dynabar large voice coil is more difficult to design and manufacture, and the cost is higher, so the price is still very expensive. If you are not an enthusiast, it is not recommended to choose. Let me tell you about it.

BT-audio red EX home theater,

The Red EX Cinema belongs to the American Sound Stage Department. Using the world-leading integrated loudspeaker unit technology, the treble can achieve 100% distortion-free, and at the same time, it can obtain amazing sound field effect. While keeping the treble transparent, sound stage is exquisite and broad, with obvious contrast between dynamics and dynamics, and the overall sound stage has a strong sense of energy, which can be called a classic in sound stage cinemas.

Mahogany and leather are used to make speakers gorgeous and elegant. The color of the cabinet is mainly red and black, and Chinese and American styles are perfectly integrated, giving people a magnificent and profound sense of stability from the whole to the part, highlighting the identity of the speaker owner as a successful person.

I hope my answer can help you.
