Description

Precautions:

1. When soldering the power switch, try to control the welding time within 3 seconds to prevent the switch from being damaged by excessive temperature! (You can tin the switch pins first, then solder the wires)

2. Due to the limited current output by the USB port of the computer, if it is plugged into the USB port of the computer to supply power, the sound quality will be greatly reduced when the volume is turned up or the bass is heavier, so it is recommended to use a separate USB power supply (output 1A or more) to power the speaker.

The supporting USB power supply can provide sufficient power for 2A, which can maximize the effect of the speaker.

3. Since the digital volume control in the power amplifier chip has a large gain, when increasing its volume, be careful not to make the input signal too large to cause the signal to cut and limit the signal, resulting in sound distortion.

Working voltage: 5V Current: more than 1A Amplifier power: 3W*2 Weight: a pair of 420g

Power supply mode: mobile phone charger, power bank, computer (not recommended, because the computer current is too small will affect the sound quality, it is recommended to use 2A current power supply)
