常见问题:
问:我所有的线都接好了,为什么没有声音?
答:1.检查机器是否通电,通道指示灯是否亮,相应的输入通道是否连接正确。
2.检查后级连接是否正确。
3.若以上都正常,检查输入的播放设备是否静音、暂停了、或者音量处于最小状态。
问:为什么声音出现破音?
答:本机虽为 DAC 解码器,但作为前级产品也是有放大作用的,如果后级设备音量调到最大,而前级也
到最大,那就很容易失真,此时你只需要将前级或后级音量调小一些就可以。
问:为什么我插上输入线后不接播放音源,音箱会有很大的嗡嗡声?
答:使用了不带屏蔽的信号线空载时,会有干扰信号进入到功放进行放大,建议你换成带屏蔽的信号
线,或者拔掉信号线。
问:蓝牙声音为什么断断续续的?
答:测试蓝牙距离时,蓝牙在无任何遮挡物的情况下,10 米内声音没有出现卡顿和断开连接为正常。
(注:路由器会对蓝牙信号产生干扰,不要靠太近

FQA:
Q: all my wires are connected. Why is there no sound?
A: 1.Check whether the machine is powered on, whether the channel indicator is on, and whether
the corresponding input channel is connected correctly.
2. Check whether the rear stage connection is correct.
3. If all the above are normal, check whether the input playback device is mute, paused, or the
v
olume is at the minimum state
.
Q: why is the sound distorted?
A: Although this machine is a DAC decoder, it also has amplification function. If the volume of
the power amplifier is adjusted to the maximum and the volume of the DAC decoder is also adjusted
to the maximum, it is easy to be distorted. At this time, it is only necessary to reduce the volume
of DAC decoder or power amplifier.
Q: Why does the speaker make a loud buzzing sound when I plug in the input cord and don't connect
the audio source?
A: When the signal line without shielding is used, there will be interference signals entering
the power amplifier for amplification. It is recommended that you replace the signal line with
shielding or unplug the signal line.
Q: why does Bluetooth sound get stuck?
A: when using Bluetooth to test the distance, it is normal that the sound does not get stuck or
disconnected within 10 meters without any obstructions.
(Note: the router will interfere with the Bluetooth signal. Try not to get close
warning!
1. Please do not open the machine shell. Improper operation may cause electric shock.
2. please use the regular manufacturer of switching power supply, otherwise there will be
the risk of damage to the machine.
3. Do not put the machine in a high temperature or humid environment.
