_______________❀Product Information❀______________


1. Applicable Power Supply: It is recommended to use a 18V 19V 24V power supply with a current of 5A or more. If you only have a 9V 12V or 1A 2A power supply, you can also use it, but the power is small. Note that when you use it, the volume may be distorted and affect the sound quality.
2. Voltage and Current: The higher the voltage, the greater the current and the more output power. If you only have 12V 1A, you can bring 3‑4 inch speakers. If you are 19V 5A or above, no problem with 8‑10 inches.
3. 2 Sound Input Mode: This sound power amplifier module has two sound input modes, one is input, the other is AUX input, mode is preferred. can connect in any mode.
4. Mode: mode supports automatic reconnection. When there is no connection, AUX is inserted in AUX mode. When using AUX mode, you need to confirm that the connection of this module has been disconnected.
5. Note: The BASS potentiometer in the middle controls the bass, the right handed bass boosts, and the left handed bass attenuates. When the potentiometer is in the middle position, the bass is neither boosted nor attenuated.
6. Note: The TREBLE potentiometer on the left controls the treble, the right handed treble is enhanced, and the left handed treble is attenuated. When the potentiometer is in the middle position, the treble is neither boosted nor attenuated.
