Frequently Asked Questions
Q: Cables are connected, but no sound output?
A:
- 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.
- If the indicator light is on, check whether the VOL knob is in the minimum position. If so, turn clockwise to normal Volume
- 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 headphones make a lot of electric noise?
A: if you are not using the original factory standard power supply, please
replace the power supply before testing. Many power supply in the market have
large interference coefficients, which will cause a lot of current
sound.
Q: Why the headphone has drone when I just plug in the input cable but
don’t connect the sound sources?
A: If you use unshielded signal lines, there will be interference signals
entering the power amplifier. If you hate the sound, you are advised to use
the shielded signal lines or unplug the signal lines.
Q: Why the sound is very hard at the beginning, the 3 frequencies is not
very clear, but normal after a day use?
A: The tube is a very sensitive device with good effect once the
temperature should reach a degree commonly, normally about half an hour later
the voice is very natural.
Q: Can I update the tube?
A: yes, we have tested and matched 6k4/6j4 / GE5654/6ak5/66*1n1n in our
factory. It can be replaced directly. The sound will be different with
different tube.
Q: Can I replace the tube without power off ?
A: no, it is very easy to burn the tube, because the machine works under
high voltage and the hot plug will damage the tube & machine, also will hurt
the people
Q: Can this machine connect to the phonograph/phonograph?
A: At present, this model does not support the signal, input of the
phonograph/gramophone because the output signal amplitude of the
phonograph/gramophone is small, so it needs to increase the phonograph
amplifier.
WARNING
- Please do not open the shell without permission. Improper operation may cause the danger of electric shock.
- Please use the power supply of the regular manufacturer, otherwise it will damage the machine.
- Please do not use the machine in a high temperature and humidity environment.
- Please don’t replace the tube when the power on, otherwise the tube & machine will be damaged
- Please don’t use the non-matched tube, otherwise, the tube & machine will be damaged
