1.关于底噪?
答:断开功放的输入连接线,把功放的声音开到最大,这样可以判断底噪的来源是功放本身还是音源本身。
2.输出有杂音?
答:首先,换首歌曲试一试,看是否是歌曲本身的杂音;其实,检查线材是否接触良好可靠;然后,前级输出的信号是不是标准的2.0 Vrms,如果超过这个幅度,功放输出就会有噪音。 展开

Background Noise?
Answer: Disconnect the input cable of the amplifier and turn up the sound to the full position, then you can verify if noise is from the amplifier or the sound source itself.
Noise in output?
Answer: Firstly, please try to play another song and check if the noise is within the song itself; secondly, check if the cables are connected firmly; lastly, check if the front-end output signal is of standard 2.0 Vrms, if it is over this data, the amplifier output will make noise.

1. Background noise?
Answer: You should disconnect the power amplifier input line, turn the power amplifier voice to be the most, then, you can estimate the noise is from power amplifier itself or audio source itself.
2. Noise form Output?
Answer: First, try another song to see whether the murmur of the song itself; Then, check the wire whetheris well connected and reliable or not; Last, see the level of output signal preceding stage whether it is the standard 2.0 Vrms, if beyond, it will have noise.
