Specification
Brand : YWBL-WH
BulletPoint1 : power amplifier board, with two audio input methods, AUX and , and adopts 5.0 version, which has higher efficiency and longer distance.
BulletPoint2 : 2.1 channel, the maximum output power is 2×50W+100W. With antenna and antenna base, the is better, the efficiency is high, and the anti interference ability is strong.
BulletPoint3 : It has short circuit , over current, over heating, and anti reverse to prevent it from failing completely. And when an overload occurs, the device protects itself from damage.
BulletPoint4 : Copper DC connector + shed type terminal, can withstand high current, does not generate heat, and is not easy to damage the wires. No DC head , compatible with the input power interface of this product.
BulletPoint5 : With bass, treble, subwoofer frequency and volume control, you can easily adjust the volume. It can be widely used in shop solicitation, home theater, speakers, etc.

Note:
1. The power switch on the board is a standby switch. After the switch is turned off, the machine is in a low‑power standby state. Turn off the power completely or unplug the DC plug on the machine for a long time.
2. Please use a power adapter with sufficient power to connect to the power amplifier board, otherwise the sound will be distorted.

3. If the audio input is sufficient and the power supply voltage/current is sufficient, there is enough output power. The higher the power supply voltage, the greater the relative power. Speakers with different impedances will have different output . In the of sufficient voltage and current, the greater the ohm of the speaker, the smaller the relative sound power. Please make sure that the power of the adapter is greater than the actual working power of the amplifier.
