Specification:
Working voltage: 5V
Current: 1A or more
Amplifier power: 3W*2
Power supply: mobile phone charger (not recommended for rechargeable batteries and computers, because the computer current is too small will affect the sound quality, it is recommended to use 2A current power supply) directly welded power supply holder directly plug the line on the line. 4 shielded wire one by one corresponding welding on the line, D1 D2 VCC GND.

Notes:
1. When welding the power switch, try to control the welding time within 3 seconds to prevent the switch from being damaged by the high temperature! (Tin can be added to the switch pins first, then solder the wires)
2, because the computer USB port output current is limited, if plugged into the computer USB port power supply, adjust the volume or bass heavier sound quality will be greatly reduced, so it is recommended to use a separate USB power supply (output 1A or more) to power the speaker.
3, the back of the sop8 SMD components, the purchase of loose parts need to be sure to buy oh.
4, due to the digital volume control in the amplifier chip has a large gain, so when increasing its volume take care not to let the input signal is too large and the signal produces cutting limits, resulting in sound distortion.
5, the acrylic housing needs to be assembled by themselves, there are positive and negative, installed incorrectly can be installed in reverse. It is relatively simple. Need to tear off a layer of paper that is the transparent shell.
Note: The main stereo has a power switch, while the secondary stereo does not, the purchase of a single stereo with a power switch. There is a volume adjustment knob, and spectrum adjustment knob.
