Bluetooth Amplifier Board 2 * 6W
Product Information:
● Product model: SW-HF69B
● Bluetooth amplifier board: standby heating small stereo sound quality is good, suitable for small Bluetooth speakers
● Output power: 6W+6W dual channel stereo
● Applicable horn impedance: 6 ohm, 8 ohm (if the horn impedance is too small, there will be loud sound breaking)
● Power supply voltage: 5VDC or 3.7V lithium battery (if the wiring is too long in use, the battery is dead and the voltage is too low, the volume will be slightly turned off and the sound will be broken)
● Power supply current: the full power is more than 1A (when the power supply current is insufficient, the sound will break when the volume switch is used again)
● Charging interface: when using lithium battery for power supply, the charging interface can be powered by 5V or the mobile phone charger can charge a single lithium battery (the charging management circuit limits the high voltage of the battery to 4.2VDC)
Friendly Reminder:
When the sliding switch is ON, the Micro USB port is a charging port, which can only work when powered by the lithium battery. When the sliding switch is OFF, the Micro USB port is a power supply port, which can work without the lithium battery.
Turn up the volume when the product is in use. If the horn breaks, please check the power supply. If the output current of the power supply is not enough, intermittent sounds will appear. Users who do not know about it should not buy it. It is not recommended to use a horn with low impedance.
