A: 1.Check whether the machine is started and switched to the corresponding input channel.
2.Check whether the volume knob pointer is in the leftmost state. If it is in the leftmost
state, turn the volume knob to the right.
3.If the above two points are normal, check whether the playback device of the input sound
source is paused, muted, or the volume is at the minimum.
Q: All my cables are connected, but there is no sound output?
A: The input level may be too large. If the volume of the sound source equipment is adjusted
to the maximum, and the volume of the machine is also adjusted to the maximum, it is easy
to be distorted. At this time, turn down the volume of the sound source input device or
machine.
Q: Why is the sound distorted?
