Anonymous users2024-01-24I don't know if the horn you are talking about is a ceiling speaker, that is, the kind of horn installed on the ceiling in conference rooms and public places, if so, any other power amplifier is not good, because the impedance of this kind of horn is very high, and each horn has an independent transformer, that is, an impedance matcher! This kind of horn should be pushed by a special constant pressure amplifier! Otherwise, either the sound will be very small, or the power amplifier will be burned!

Anonymous users2024-01-23The power amplifier should amplify the signal, and the output of DVD and so on should be connected to the input port of the power amplifier. The power amplifier is connected to the speaker, there is a fixed mouth, the left channel, the left speaker, the right speaker (the positive and negative should be consistent, the red port is connected to the red port). I don't understand HI me. Line by line.

No! Power amplifier is required, and the size of the power amplifier is determined according to the power of the horn.
It may be a motor spark interference from the treadmill. The treadmill uses a DC brush motor. Carbon brushes generate electrical sparks, which are the most widely used sources of dry sparks. If you understand it, you need to shield it from running, or connect it to the filter circuit in the power line and motor line.
Yes, but depending on what kind of horn you speak, there is a piezoelectric type, which has an impedance of more than 300 ohms, and the other is a coil, but its impedance is relatively small!
As long as the specifications are the same, they can be replaced. Remember to buy 304 stainless steel.
