The amp has three knobs on the front which allows you to adjust treble and bass as well as the volume. There is a metal switch that powers the unit on/off with a very small red light letting you know when the amp is powered on and blue light when bluetooth is connected. I do hope Fosi Audio have sent a model to @amirm for testing but I thought I would share my opinions in this thread in the mean time. Common feature of Class D power amplifiers is that they can cause serious noise when used with a radio, so we do not recommend using the BT20A with a radio or too close to it.
Step 2: Turn on the Bluetooth on your phone and search“Fosi Audio BT20A”, after connecting toBT20A, the indicator light shows blue light. Thanks for sending this in for testing and to @amirm for his time in doing so. Also very kind of Fosi Audio to offer ASR members 20% off, kudos. Onkyo M-5010 is a simple, reliable and minimalistic solution for your sound system – stern and affordable. Notice the great channel match in addition to very good SINAD which represents noise and distortion. Same is true with 32 volt supply: Ensure that there is no interference from other electronic equipment between the BT20A and the audio source.Fosi Audio BT20A has 100 Watts*2 MAX power output, the Fosi Audio BT10A has 50 Watts*2 MAX power output. Overall, I’m very impressed with the unit - it doesn’t get hot or prevent it from staying on all the time, takes up very little space, and at least with my setup I can listen to music and watch movies from the laptop without having to turn it on and off every time the amplifier. The sound quality is much better than my previous amp which was part of a multi-component system. The speakers reproduce a much cleaner sound, the dynamics are better, the bass is much cleaner. One of the main pluses is that there is no annoying static noise, which after replacing my old amplifier with the Fosi Audio one disappeared. What truly sets the Fosi Audio BT20A Pro apart is its remarkable audio performance. With 300 watts per channel, it delivers a powerful and pristine sound that is very pleasant for my ears. Whether you’re immersing yourself in music, enjoying a movie night, or gaming, this amplifier consistently reproduces sound with depth, clarity, and accuracy. It gracefully handles a wide spectrum of audio frequencies, ensuring that every note and sound effect is crystal clear. This essentially means that you can enjoy multiple genres of music, and all the details will be remarkably well presented. Here we want to give an exclusive 20%-off discount promo code for the BT20A Pro to all ASR fans. (Valid from today to April 30.) The Fosi Audio BT20A is ideal for anyone looking for a small and affordable speaker amplifier. As long as you’re expectations are realistic, there’s little chance of being disappointed. If you need an amp for a budget or secondary system and don’t want to spend a bundle, the BT20A is the perfect solution. At this price, you couldn’t ask for more.
Now, let’s talk about the PROs of owning this little amplifier next: The Pros of Owning the Fosi BT20A Amp Size:I guess the review is out now due to embargo issues as it has just come out across Europe using the coupon or I too bought one of these for around €70, glad it wasn't a waste of money other than a slightly load-dependent frequency response (but less so than other budget class D implementations with tone controls), it seems to me you can't expect much more from a product in this price range. I reviewed the original BT20A last year and there are some notable differences between the two units that may just tip the scales in favor of you upgrading to the Pro version. Fosi Audio BT20A PRO is an upgraded Bluetooth 5.0 HiFi stereo amplifier with PRE-OUT port, which can be used as a preamplifier. The BT20A PRO supports RCA/Bluetooth input, suitable for most passive speakers as well as active ones.
It is also nice to see so much power coming out of this little box with the beefy 48 volt power supply, showcasing the advancements in amplification density we have today.

OK...i am an audiophile by osmosis only, with no real knowledge of electronics. But I have met a few who do.
