TUBE A3-PRO Vacuum Tube Preamplifier With Bluetooth 5.0

1. The product is a Vacuum tube preamp, not a power amplifier or phono amplifier.And it can not be used in cars,turntables ,also cannot be used directly for headphones, speakers,pls see the product Connection Diagram！

2. Do not use cheap audio signal lines These lines are not shielded by themselves.the probability of the bottom noise current is very large, it is recommended to use a good audio cable or power supply.

3. Make sure that there is no problem with your own audio source. The preamplifier has its own preamplifier function. If the audio source itself has noise, then the preamplifier will only amplify its noise.Please use a good sound source test.

4. Check whether the tube is plugged into the base before to use.Be sure to the machine is energized and working normally.

5. The preamplifier has 3-5 times power amplification. If the sound is broken, you can adjust the volume control to control the power output to prevent breakage.

6.Because the production batch is different,Blue/AUX input select button have a little different,Pls know it.
