Frequently Asked Questions:
Q:All the cables 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 sound is cracking?
A: This product is for the tube preamp, but also can be used as preamp, If post equipment is max volume & preamp too, it's easy to distortion, you just need to turn down the volume of the equipment, then ok.
Q: Why do loudspeakers 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 coefficient, which will cause a lot of current sound.
Q: Why the speaker has noise when I just plug in the input cable but don’t connect the sound sources ?
A:1.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.
2.Check if the grounding of the player is connected. If the ground wire is not connected, there will be a lot of noise.
Q: Why do I use MM to put input, it has no sound?
A: Check if the pre-stage input is still plugged in. If the pre-stage input is plugged in, then the input will not sound, and the pre-stage input line must be unplugged.
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 6k4/6J1/6j4/GE5654/6ak5/66*1n，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.
