Frequently Asked Questions:
1: All the cables are connected, but no sound output?
• Check whether the display screen is bright or not. If the display
screen is still not bright after starting up, you can find an output
of the same voltage (must be 12V) in the test to determine the
machine failure or power failure.If the display screen is bright,
check whether the corresponding input signal is correctly
selected.
• 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
2: Why does the sound is cracking ?
• This product is for the DAC decoder, 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.
3: Why do loudspeakers make a lot of electric noise?
• 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.
4: Why the speaker has drone when I just plug in the input
cable but don’t connect the sound sources?
• 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.
