Specification Brand : Geuxe BulletPoint1 : APPLICABLE: Bluetooth 5.0 power amplifier board with 36x25x10mm / 1.42x0.98x0.39in heatsink, applicable power supply DC12‑24V 5A and (24V battery pack cannot be connected), applicable speakers 20-100W, 4-8 Ω. BulletPoint2 : CAUTIONS: Amplifier board will only have enough output power if the sound input is sufficient and the power supply voltage and current are sufficient. The higher the power supply voltage, the higher the output power, the smaller the speaker impedance, the higher the output power. Please make sure the power of the power supply is greater than the actual power of the amplifier! BulletPoint3 : STABLE PERFORMANCE: Bluetooth digital power amplifier module features Bluetooth 5.0 with a distance of up to 49 feet (unobstructed). Also, this amplifier board has a 3.5mm AUX sound input. BulletPoint4 : DC CONVERTER PLUG: Amplifier board can use commercially available DC adapter (plug specification 5.5mmx2.1mm) to basically meet the needs of ZK MT21 Bluetooth power amplifier board. If your existing DC power plug is not 5.5mmx2.1mm, there is no problem, because we include a DC adapter in the product. BulletPoint5 : MULTIPLE : Bluetooth digital power amplifier module has multiple mechanisms to ensure its . It has short circuit , over current, overheat and anti reverse connection .
