Description:100% brand new and high quality!
With reasonable optimization, the performance is more stable, and the performance of the tube is increased by 10%.
This machine uses a single 12V AC input, so you don't have to worry about finding a high voltage power supply.
This board comes with a booster, allowing you to enjoy the charm of high-voltage tubes under low power.
Can effectively filter the digital flavor, the human voice is better.
Bold and strong, cost-effective!
Instructions:
1, AC 12V input: DC3.5/5.5*2.5 mm socket, AC 12V power adapter, if you want to use a plugless AC 12V transformer, you need to solder the power line on the circuit board.
Remember: you can't use DC power input, otherwise it won't work!
2, left channel input / right channel input: for the audio signal input terminal, can be connected to mobile phones, computers, M3, MP4, and other music players.
3. Left channel output/right channel output: It is the audio signal output terminal, which can be connected to the audio signal input end of the power amplifier and power amplifier board to provide bizarre music enjoyment to the later stage power amplifier!
4, power switch / volume knob: turn the knob counterclockwise just start to reduce the volume, when the volume is off to the minimum, if you continue to rotate, until "tick", then the power is off,
the light is off; in the closed state, Turn the knob clockwise and hear a “tick” sound. The light is on, indicating that the power has been turned on.
At this time, the volume is the smallest, and then continue to rotate clockwise to increase the volume.
