FAQ:
When I turn it up, the sound will freeze, the sound quality is not good, and it is intermittent. But when I turn it down, it can play normally.
Stuttering is caused by too small power supply. This power amplifier board has a total output power of 200W per channel. When choosing a power supply, it is recommended to choose a 24-32V one, for the sound quality effect is better. The maximum voltage does not exceed 36V, and the current is above 10A.
Poor sound quality is caused by too low voltage. If the sound of the power amplifier board is loud, the voltage must be high. The higher the voltage, the better the sound quality. If the power supply is about 14V, the sound can only be adjusted to 50% without distortion. If you want to adjust the sound to the maximum, you must supply over 24V!
Suitable for 200W dual-channel loudspeaker. It uses TDA7498E chip, a class D audio amplifier IC chip. It is powered by a single power supply. Mainly used in home theater and active speakers. Its sound quality and performance are better than similar amplifiers.
