We recommend that it is not used in applications requiring high volume. The audio output power of 2x3W is sufficient for many applications. However, if you need high volume, this power may be insufficient. When high volume is desired, noise ( crackling ) occurs.

The audio connection cable being of shielded type causes the noise to decrease.

     It is a small amplifier board using the Pam8403 integrated circuit. It has stereo 2x 3w audio output. There is a potentiometer on the board for volume adjustment. It is used in many areas such as television, radio, warning announcement systems. It is suitable for use with 4 ohm speakers. It can be used for long periods.
