Review: Soooo Many Applications - Love this Product - I am a big fan of Fosi amplifiers. They have a very small footprint, they are very easy to use, they address a variety of audio needs, all their models are well priced, they are extremely easy to hook up, and they have the power to generate great sound on both bookshelf and floor speakers. I use them in my home in different rooms, in my office, and outside by the pool. I use them to carry sound from my family room amp to sync into different rooms, to expand the sound of my TV, to control and play music in remote areas like the pool. With the small compact size and reliability they have also made a great addition for music and expanded TV sound in airb2b rental properties. As a testimonial to my satisfaction with Fosi -- this is the seventh Fosi amplifier I have purchased in the last three years. I purchased this Fosi DA-2120c to use in my office. The DA-2120c provides a variety of inputs including Bluetooth, Aux, Coax, USB and Optical. Connecting the amplifier in my office I am able to stream sound from the TV using optical interface, expand the sound from my PC using a USB connection, or I can simply play music from my phone via Bluetooth for background sound. Quality of the DA-2120c Unit: The amplifier is made out of aluminum, small, light weight and sturdy. The display on the front is OLED and very easy to see / read the source and volume level. The 2.1 stereo system easily powers passive speakers on a left and right channel, as well as a sub-woofer. While I typically use them for bookshelf size speakers, I have also used them to power larger floor speakers without issue. Package includes the DA-2020c unit, low voltage power cord, a 2-ft optical cable and the remote control. Installation: Hooking up the DA-2020c Fosi unit is extremely simple. It is truly plug and play. Connect the speaker wire to the right and left channel screw connectors, plug in the sub-woofer cable into the pin slot, plug in the electric cord and plug in any input cables you would like to use. Or as I do in my airb2b rentals -- you can simply set up the interface to use Bluetooth and power the audio speakers. The unit is so small and compact you can put them anywhere. In my airb2bs I put the amp on top of the kitchen cabinets so the amplifier is concealed, but still easy to access and use from your phone. How I use my Fosi Amp(s): I use my Fosi amps for a myriad of applications. I most often connect from my phone and use a music app like Spotify, desertcart music, Pandora, etc; but I can also Bluetooth directly from my desertcart Echo to expand the sound and use all the functions of Alexa; I use the optical cable interface to expand the sound of my TV or to have music carried from the larger amp in our family room to sync music throughout the house. I have also found a great application with TV installations where I use the Aux or optical interface and I control volume and stations with my television remote; or I use the USB connection interface to expand the sound of my PC. For Bluetooth pairing to the Fosi amp is very easy. While you cannot name the Fosi Bluetooth source, every model of Fosi Amp has a different name when you go to sync. While you can control volume and input sources from the Fosi device itself, I usually manage everything from the source – my phone, the TV, Alexa, or a larger amp in another room. When I need to I can use the handy remote control for the Fosi unit, but for most of what I need is volume control and doing it from the audio source gives me everything you need for control – When I need to change the input I use the Fosi handy remote control. I have implemented the DA-2120c in my office to stream audio from my computer, enhance the sound from my office television, and to simply play music from my phone in the background. The only feature I wish the Fosi amps included was the ability to Bluetooth connect to multiple Fosi amps at the same time. To summarize – the Fosi amp is dependable, reliable, super easy to hook up, easy to use, and has a wide range of applications. Love the product……...
Review: Works very well. - I needed a small audio amplifier to power two passive Yamaha speakers, 10", 10-140w since I had gotten rid of my old Pioneer receiver/amp but not the speakers. I needed this for my older Sony XBR2 TV for improved sound over the internal speakers and wanted a small, powerful amplifier that had a remote. The Fosi DA 2120C arrived in perfect condition, was easy to hook up with RCA jacks from the TV. The sound was great and the remote worked well to adjust bass and treble with and without the Loudness function to get it sounding the way I wanted. I decided to use the optical cable that came with the unit to further improve the sound, however it did not work. I contacted Fosi by email and they responded quickly. we tried several things but could not get it to work. Trying the amp with optical cable on another TV did work very well using the optical input on the amp. After much research I found that Sony XBR2 and XBR3 TVs will produce digital output through the audio optical out only if the TV receives the signal through the Coaxial, (Cable) input, not with HDMI, so the problem was not with the Fosi Amp but with my TV. The reason I did not use the cable input to the TV was because, not being a smart TV and not wanting to rent another cable box, I had purchased a Google Chromecast TV to get reception. It works great but can only hook to the TV via HDMI. I found that I could work around this problem if I purchased a HDMI to HDMI + Optical adaptor for around $25, but since I was only using 2-chanel stereo vs 5.1, I decided not to go any further. It sounds great using the RCA output from the TV. I easily paired my cell phone to the Blue Tooth of the amp and it played music with excellent quality. You can power on/off and change input and volume on the amplifier or with the remote. Tone setting are done with the remote. There is no balance control, being the only thing missing. I had an unusual issue that most people won't have. Bottom line is that the Fose DA2120C is a great little amp and if you have any issues in getting it to work with your system, the Fosi support is very responsive and they seem determined to make things right.

## Questions & Answers

**Q: Does the amp have a direct mode to bypass all EQ?**
A: The remote has a RECOVER key that alternates between TONE_ON and HiFi. HiFi returns the response to flat. TONE_ON returns the response to your previous tone settings.

**Q: Will this be able to drive a pair of wharfedale 240's (nominal impedance 4 ohms). what is the watt per channel for 4 ohm speakers?**
A: The power supply for this is 32V at 5A which is 160 Watts.   I'm not quite sure how it is supposed to generate a RMS power output of 120watts x 2 channels (all 2xchannels driven). Maybe 120 Watts per channel (one channel driven). I'd suspect it only pushes 50-60 watts @ 4 ohms all channels driven and it says something to the fact in the trouble shooting area of the description. Though I've never measured this myself.

**Q: It's possible to bypass the internal dac of the amp? i'd appreciate if someone can explain me the process.**
A: From my understanding, the analog RCA input goes through an ADC and then internal DAC (the sample rate on analog in says "48kHz").  So there would be no way to bypass the internal DAC, even using analog in.

**Q: Can I reprogram my tv remote to control the volume?**
A: I couldn't say if you can reprogram your tv remote, but maybe the following will help. I have several devices hooked up to play sound through the Fosi Audio, which I keep at a set volume of 54. I then use the volume control of the particular device I am listening to. I never need to touch the Fosi's volume control. For example, my "default device" on the Bluetooth connection is an Amazon Echo. If I want to adjust the volume, I simply say, "Alexa, louder" or "Alexa, lower by two." (By the way, the Fosi's sound quality is excellent.)
