We recommend that it not be 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 a shielded type causes the noise to decrease.

     It is a tiny amplifier board using the Pam8403 integrated circuit. It has a stereo 2x 3w audio output. It works with DC 5V over the micro usb socket. It is used in many areas such as television, radio, announcement presentation systems. It is suitable for use with 4 ohm speakers. It can be used for long periods.
