Review: Great 2.1 speaker + sub solution - This speaker amp works very well. I connected 2x 6ohm 120w speakers, and a 130w sub and they sound great. SUMMARY: I had a 5.1 surround sound system (2010 model) but the receiver died. The speakers I had for it connected through the bare speaker wire pinch connectors (no banana plugs or RCA). This amp had the connections I needed for those speakers. I bought some banana plugs to go with it to make the setup easier (I would recommend this). I'm no audio expert so I can't tell you how this would work as a DIY amp for an audiophile setup or how amazing the audio quality is compared to other products on the market. I can tell you that this was just about the ONLY 2.1 amp I could find for the speaker and sub that I had. Build quality simple and is not flashy; but it's solid and looks as the picture shows. It doesn't heat up like my old receiver did. It is pretty small so that could either be great, or not so great--so you decide. It's about the size of my hand. I WOULD recommend this amp. With that said the quality of sound is good for me. I just needed 2 speakers and a sub for my PC and this amp powers them just fine. It's rated up to 200w and 12ohm. I listen to music and watch videos using speakers, but I play all my games using a headset. The system gets pretty dang loud and so does the sub. (obviously compared to 5.1 it's not as powerful). You get the idea of why I got this though. Read the instructions first before you hook it up to your power. This comes with an AC-DC converter (much like your laptops) that is rated for 19v DC. Needless to say there is a lot of power initially going to the capacitors. So connect it to the amp, then the wall. Not vice a versa.
Review: Audio Performance Impresses - The Fosi BL20C 2.1 amplifier form factor is small and compact. It conveniently fits nicely in a variety of different locations. The case is solidly built metal. The control knobs rotate smoothly with stepped detents. It fits nicely just beneath one of my monitors. Audio Performance Impresses. The amp power pumps out the loudness DBs upon demand. I run with the amp cabled directly to my PC. I bought this amp primarily for listening to music. Depending on the file format type, quality of the file source, and media type, the sound bass and treble defaults can vary quite a lot. The BL20C allows the listener to custom tailor and tune the listening experience, based on preference and the variable sound source. I'm running a pair of Klipsch R-41M bookshelf passive speakers, along with a powered subwoofer Polk Audio PSW108. Both are 8 ohms. The BL20C allows me to custom control all the speakers from a single control source. I found 1st setting the PC OS 'sound' level at about 80%, then secondly tuning the amp bass/treble control levels to the best front speaker sound, then 3rdly setting the independent active sub bass woofer volume level and low pass filter level. After this, I only needed minor amp control bass/treble adjustments based on the music song and source. Just to see what my system was max ultimately capable of, I set the PC OS sound output to 100%, set the BL20C amp bass/treble controls to the middle position, played a musical song from a music file source that I had ripped from CD, then cranked up the amp volume gradually to max. It was very loud and clear. My speakers are rated for the amp wattage power output, so make sure your speakers can handle the Wattage output. My next BL20C test with the Bluetooth functionality. I found if I simply flipped the front panel switch to "BT/USB", the device started broadcasting a BT signal. My mobile device instantly recognized the signal. I added/accepted the BL20C amp device to my phone. Playing some songs from my mobile device, the BL20C received the music stream from my phone fine, then outputted the audio signal output to my speakers. Considering the music source was coming from a phone, the music quality, volume, and adjust ability was impressive. I still haven't tried out U-Disk features yet. The Fosi BL20C 2.1 amp accomplishes what I set out to do. I am certainly enjoying it. The interface versatility is definitely a plus.

## Questions & Answers

**Q: How can this amp deliver 200w (output power: 50w+50w+100w) if the power supply only delivers 100w? at the same time it says the psu is ’matched’?**
A: I believe some of the specs for this amp are inaccurate and I'm not sure what the actual ratings are. Regardless, I have been running this amp for a year with speakers from a 540W Sony MHC-EC909IP https://www.amazon.com/Sony-MHCEC909iP-System-Discontinued-Manufacturer/dp/B003GZDB1Q after the main unit broke. This amp drives the speakers just as well as the Sony unit and I was happily surprised with its performance. Again, Im unsure of the actual specs, but I wanted to give you a reference of the amps actual capabilities.

**Q: How can this amp deliver 200w (50w+50w+100w) if the power supply only delivers 100w?**
A: With the power supply it comes with, it can't.  Most people will be happy with 100w total watts, especially since it can be divided between the channels moment by moment.  That's better than a 25x2+50W amp, since the sub on this could be driven with all the input power, if there was no audio needing the L & R.   However, yes, if you want to get the full power out of this amp, and it has honest ratings, and won't distort or overheat at full output, you'd need to buy at least a 250W PSU (assuming 80% efficiency at full load).   A 24V 10A supply isn't unusual, but will run about $40 if you don't get the absolute cheapest one out there.

**Q: Can i use an a/b switch at the input to switch between a cd player,and,a turntable?**
A: Yes you can !!!!! But you will need a pre amplifier for the turntable if it a mag. cartage !!!!!

**Q: if I turn up the master volume does the sub volume increase with it, or do I need to adjust the bass volume to not be drowned out by speakers**
A: The Master volume controls ALL the channels, including the subwoofer. The BASS VOL  volune knob adjusts the subwoofer volume only, so you can set it as desired relative to the main L & R channels, along with the FREQ knob, which adjusts the subwoofer hi-frequency cutoff.  Once you’ve got the proper balance set, then you use the Master volume to adjust the overall listening level.  The TREBLE and BASS knobs adjust these frequencies for ALL channels, according to you preference.

### ⭐⭐⭐⭐ Works well, Power supply is small (Beware)
*by A***R on June 19, 2023*

I needed something outside to power my dual channel Polk Audio Atrium8 speaker. I actually went out and bought a Sonly receiver, your typical brick bulky receiver. I then found these little units and wanted to give them a try. I opted for this Fosi Unit I have the little thing mount behind the TV (On the back of the TV) so its out of sight type deal. Sound is great, better than the giant receiver One thing to note and there is another review about this, this power supply it comes with cannot produce 320w with the 24v/4.5A power supply. I upgraded the power supply to the 32v/5A and this gave me about 80W per channel and was good enough. I did email Fosi Audio support and asked what power supply is out there that can produced the 320W and they where unable to find me an answer. So why they have this listed at 320W, I don't know but just be careful. I think out of the box you will get 60W per channel at best. With this I give it a 4 star review. Aside from this the unit does well. Have it hooked up to the TV so football games are nice and clear and the unit also has Bluetooth
