Q: All my wires are connected, but there is no sound?
A: 1 . Check whether the machine is powered on and whether the VU level meter light is on.
If there is no response after startup, you can find a power supply with the same voltage
output (must be DC24v-48v) for test.
2. If the startup is normal and there is still no sound, check whether the input and output
lines are correctly connected.
