Description

Pcwncvxa Basic parameters: Power supply: DC12V2A ( needs to be regulated by 12V, not higher than 12V) Machine size: about 129* 100* 35MM (without tube height) Panel function: switch treble adjustment bass adjustment total volume Note: 1. 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. 2. 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. 3. Make sure that there is no problem with your source. The preamplifier itself has a preamplifier function. If itself is noisy, then the preamplifier will only amplify its noise. Please use a good source test. 4. Check if the tube is plugged into the base. Please insert the tube and the base. Be sure to insert the tube in case of power failure. Note: Power supply is not included in the package. You need to buy 12V2A power supply by yourself.
