DFR0799 Bluetooth Amplifier won't pair

My SKU: DFR0799 Bluetooth Amplifier has been working fine until recently when I tried to use it and it wasn’t paired with my PC anymore. Nothing I have tried has worked to get them to pair.

Hi, does your PC detect the bluetooth module?

It used to, but now it can’t see it when it scans

Hi John,

Welcome to the forum :slight_smile:

What power supply and spearkers were you using the amp with?
Also does the indicator on the front light up when powered and enabled after turning the volume/power knob?


I’m using an old laptop power supply (18V). It worked well until recently.
I’m driving some old 8 ohm 30 W speakers that also worked well.
The blue power light comes on nice and bright.
Occasionaly and at random I get the three chimes from the speaker as if it is pairing.
