Operation Steps:
1
.Make sure the VOL turnto the minimum
2 .Install the tube into the base of the tube according to the direction (the tube is not left
or right, check whether the pin is deformed before installing the tube, and the deformation
can be corrected by hand).

Frequently Asked Questions:
ables are connected, but no sound output?
A: 1. Check the POWER indicator is on, press the POWER button if the light is still off, At this point
you can find a same output voltage power supply (must 12V) to check if the machine or power supply
failure.If the POWER indicator light is on, check whether the corresponding input signal is selected
correctly.
2. If the indicator light is on, check whether the VOL knob is in the minimum position. If so, turn
clockwise to normal Volume
3. If both of the above are normal, check the input device if it is paused, mute, or the volume is
minimized
Q: why does the volume of the machine stay the same, while the sound of different audio sources (such
as CDS and mobile phones) is different?
A: The output range of different types of audio source devices is different, the mobile phone is usually
0.35mV, and the CD is 1V.The signal output amplitude of the sound source will directly influence the
volume
Q: Why do headphone make a lot of electric noise?
