Make sure that the distance between your device and BT20A is not too long, close your device to BT20A to have a try. Watts x2 Power Output: Fosi Audio V3 is a mini HiFi class-D power amplifier that delivers a maximum power output of 600W into two channels, ensuring a powerful and high-fidelity audio experience. I found the slogan on this box, Hifi Made Fun, kind of ironic because too me, the Fosi wasn’t really that much fun. Fosi Audio designs and builds innovative audio products with all your music in mind. Great sound, simple but elegant designs, high-quality materials, and truly useful features are what Fosi Audio is about. We sincerely hope you get as much enjoyment from our products as we’ve had to create them!

Bluetooth while it sounds clean (little or no noise compared to the A07 Pro) it just supports the SBC codec (so no AAC or LDAC)Overall comparisons with the other TPA3255 amp that I compared it with (and this is totally my opinion): Although to be fair, I put the cursor at an earlier point than for 48 volt supply (not enough measurement points there). Bluetooth 5.0 streaming range up to 39ft(12m), with bass and treble control, Simple compact design but practical and powerful, Adopt TI TPA3116D2 chip to get clear and clarity sound, no audible noise, dead silent when nothing... That aside, note how the response is more or less is flat in audible band with the treble and bass controls set to their detent, center position. But, let’s talk about the definition of “fun” because maybe my idea of fun is different from Fosi’s and even yours.

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. Take a moment to tweak the treble and bass controls once you’ve fired up some music. I found that right in the middle on both the treble and bass works best for me but it will depend on your speakers and your individual preference.The tests are in 48 volt unless I say otherwise (I had mistakenly assumed it was the standard, not the 32 volt). Here is our dashboard: If your Bluetooth microphone is a Bluetooth transmitter, then yes. This amplifier is the Bluetooth receiver amplifier. This is the class D amplifier, it will cost very low power when it is in standby mode. It can be connected all the time and it is safe without power consumption. Yes, the wide voltage AC 110-240V for power input can be used inany country. You only need to match the power cord adapter of the corresponding country. Given its low price, I suspect very few Fosi BT20A Pros will ever arrive on the used market. Why would anyone buy a used one when new ones with a warranty are so cheap? This is the perfect “give it to a deserving musician or young person” integrated amplifier as you move up the component ladder. At 50 percent of its retail, it might cost as much to ship as you would get for selling it. Just give it away or recycle it when you are done with the unit.
