Mini HQ Bluetooth 5.0 Wireless Audio Digital Power amplifier Stereo board 50Wx2

Super Mini Bluetooth Amplifier with up to 50W per channel. Great for using with a mobile phone etc. We supply several customers with these that convert old car stereos etc. Lovely little amp with lots of uses!

If your after a very small bluetooth amplifier then this is the one for you. Power it up (socket and wire provided) to a 12v to 24v source. Higher input voltage and amps will give more output. 

The potentiometer adjusts the volume and has a switch for on/off, making it perfect for DIY speakers.

Precautions for use: The power switch on the board is the standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power please unplug the power cable or power source..

Questions and answer:

1. How to choose a power supply?
The power supply is critical. The higher the voltage, the higher the current and the better the output power. If you only have 12V 1A, you can use a 3-4 inch speaker. If you are 19V 5A or above, there is no problem with larger 8-10 inches but please make sure the power supply is high amp rated. If the voltage is too low, the sound will be distorted after the sound is amplified. If the current is too small, the speaker will pull the voltage low, work poorly and the sound quality will deteriorate.
It is recommended to use 18V-24V power supply with current above 3A. If you only have 9V-12V or 1A/2A power supply, it can also be used but the power is smaller. Please pay attention to the maximum volume when using it, which may affect the sound quality.

2. How to choose speakers?
Commonly used speakers are generally 8 ohms, 4ohm speakers can also be used.
