Brand : Ferwooh
BulletPoint1 : The power amplifier board PAM8403 is a small digital amplifier chip that emphasizes the advantages of the digital chip.
BulletPoint2 : The circuit of the power amplifier board accepts the reasonable configuration. With switches, potentiometers, and can adjust the volume, which is flexible and convenient.The performance filtering was upgraded to 470 UF, 1.6 mm fiber optic sheet.Efficiency can achieve 90% above, can use computer USB 5 V power supply.
BulletPoint3 : Power supply range: 5V DC; Lowest performance: 3W * 2; Dimensions: 30 x 20 x 15 mm (without protruding potentiometer lever).
BulletPoint4 : Built-in Protection: This power amplifier power of 3 W + 3 W high-fidelity sound quality, integrated noise suppression circuit.
BulletPoint5 : Appropriate configuration: The potentiometer takes on the original anti-clock body, and the potentiometer with the switch against clockwise can directly separate the energy, the circuit that uses the most appropriate peripheral configuration.
