Enjoy the best sound on your arcade machine thanks to this superb stereo sound amplifier with Bluetooth built-in. With a power of 8 Ohms, 15W X 2, you'll have more than enough power to listen to the soundtracks of your favorite retro games.

The connections to the speakers are done through the 2 outputs (LEFT - RIGHT) that the board has. For the sound source to reach the amplifier we have 2 options:

1. Connect a minijack cable from the output of the Audio source to the input of the amplifier. 
2. Pair via Bluetooth the amplifier to our sound source.

This is a really versatile sound amplifier. This board enjoys 15W x each speaker power. It is recommended to use speakers between 4 and 8 Amps. The amplifier has a frequency response of 20Hz ~ 20Khz. The SNR (signal to noise ratio) is 91dB and the output signal is 300-650mV.

The PCB of this audio amplifier also has a volume knob attached to it via a 20cm long cable. Thanks to this volume knob you will be able to regulate the sound in a comfortable way without having to use any software or combination of buttons on your arcade cabinet.

To power the board you simply need 12 volts and 2 amps for it to work. This will be enough for the Bluetooth signal to work to its 100%. 

How to use the Bluetooth function:

Just activate the Bluetooth of our device: Raspberry Pi, PC, Smartphone, Laptop, etc ... and activate the search for Bluetooth devices. The amplifier will appear with the name: SFT8850. Pair the device and that's it. The sound will be sent automatically from the Computer, Raspberry or Smartphone, directly to the sound amplifier.
