The Highfly Low Distortion PCBA 500mA DC to DC 12V to Dual 15V Audio Amplifier PCB Circuit Board is an electronic circuit board used to boost DC power from 12V to two 15V channels for use in audio amplifier circuits. Here are some explanations for this product:

Highfly Low Destruction PCBA: "Highfly" may be the name or brand of the manufacturer. "Low Distortion PCBA" indicates that the circuit board is designed for low distortion applications.

500mA: This is the maximum current output capacity of the circuit board, which is 500mA, indicating that it can provide up to 500mA of current.

DC to DC: This indicates that the circuit board is a DC to DC boost converter, which boosts a 12V DC power supply to two 15V DC power supplies.

12V to Dual 15V: The function of a circuit board is to boost a single 12V DC power supply into two 15V DC power supplies, which are usually used to power audio amplifiers or other electronic circuits.

Audio Amplifier PCB Circuit Board: This is the purpose of a circuit board, which is designed to power audio amplifier circuits. It is a printed circuit board (PCB) used to connect and support various electronic components to build circuits.

The main function of this product is to provide the required power voltage for the audio amplifier circuit while maintaining low distortion. Audio amplifiers typically require a stable power supply voltage to provide high-quality audio output.
