This finished machine is a preamplifier, not an amplifier. It should be used with a post-amplifier or an active speaker. It is not allowed to directly connect passive speakers, speakers and earphones to the power amplifier; if it is not used, the car will be burnt if the voltage is unstable.    \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e2. The probability that the normal audio line or power supply is not good enough to cause the noise at the bottom noise is very high. It is recommended to use a good audio cable or power supply.    \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e3. Make sure that there is no problem with your source. The preamplifier itself has a preamplifier function. If the source itself is noisy, then the preamplifier will only amplify its noise. Please use a good source test.    \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e4. Check if the tube is plugged into the base. Please insert the tube and the base.
