1>. Support USB sound card, free drive, plug and play (normal lithium battery power supply situation).
2>. This product has dual 5W power amplifier circuit. It can not be used in addition to the power amplifier. The output of two amplifiers can not be connected in parallel or connected to the negative electrode, otherwise the power amplifier chip will be damaged.
3>. There are two 2-8 European and 3-10W speakers respectively, and 3 European 5W and 4 European 10W horn are used. The output is stereo.
4>. Maximum working current is 5V 2A, using 5V 2A or more voltage power supply, sound quality will be better.
5>. It is suggested that a 3.7-5V lithium battery (the lithium battery needs a protective plate! It can charge a lithium battery with a USB rechargeable battery, and the USB port can not be used as a power supply port.) or a 5V adapter be used for power supply. It can not use voltage and current unstable power supply, such as dry battery, portable charger, multi-function transformer and so on.
6>. When the Bluetooth board is installed, the antenna should not be close to the metal parts so as not to affect the transmission distance.
