    How long is the wire suitable?

    1. The length of the speaker cable should be 2m~2.5m, which is closer to the length of use, and there is a certain space. For example, if it exceeds 5m, it will reduce the sound range, reduce the aftertaste and strength of the music, and cause unnecessary waste. 2. When using a rigid beam speaker c... READ MORE

    The difference between two-wire audio and four-wire audio

    The previous audio lines used 2 lines, because the transmission distance is short, and it is baseband transmission, so the second line can be satisfied. For example, early telephones. But later people's requirements increased, hoping to extend the transmission distance, so an amplifier was added in... READ MORE
