There's something wrong with the loudspeaker. It doesn't sound. Where is the trouble?
Last time I also microphone out of order, I use the winning card, the effect has been very good, bought almost 3 years ago, the first bad, contact the manufacturer, the original is the fault line, almost a week will be sent back, the effect is the same as before, so the manufacturers or consulting well, of course, the best choice for well-known brand loudspeakers, better sound quality is guaranteed not to say.
Check if there is a problem with the input microphoneNo abnormal check, is the electricity enough?If the above are no exception, then only contact the manufacturer for maintenance
First, check if there is a problem with the input microphoneNo abnormal check, is the electricity enough?
