## Questions & Answers

**Q: Can i just plug it into my pc and plug in headphones to the dac to receive sound?**
A: It requires an external power source, so I doubt it will not work with out it.

**Q: connecting this between a computer and stereo system, do I need a power supply?**
A: yes.  but if youre connecting your computer to an a/v receiver or stereo with  optical in or coaxial in, meaning it does have a DAC; then you dont need this.

**Q: Does the without ac adapter version work with any phone charger?**
A: Yes, the power input to the FiiO D3 uses USB power that any USB phone charger can provide.

**Q: Is the "Line Out" port on this an aux out port?**
A: I use the RCA outputs to feed an older JVC sound system, and it works as expected. The Line out is a 3.5mm mini jack output which will drive headphones, and it worked in that capacity for me, so it should be compatible with any 3.5mm "AUX in" input. However, I used Line out only with headphones, and not as an input to a device other than headphones.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Low cost DAC for 2 channel stereo
*by M***H on September 2, 2020*

There is nothing bad to say about this little DAC. If you need a very inexpensive way to connect the digital output of your tv into a two channel stereo, this is an excellent option. It does not pass multichannel surround sound through it, only two channel.The build quality is really nice, constructed of aluminum not plastic. It’s small and light enough to Velcro to the back of a tv. The sound quality for TV is excellent-clean and clear. I haven’t tried it for music and don’t plan on using it for that purpose so I can’t comment on that, but I imagine for the casual music listener it would sound very good.For the low price of this unit I would call it a no brainer and would recommend it to anyone who wants to connect a tv directly to a stereo.

### ⭐⭐⭐⭐⭐ Does the job!
*by H***S on June 27, 2021*

This should be built into decent AV receivers, but they aren't. My receiver only passes analog signals out to the analog outputs. That was fine when I played CDs or music from my Dish network box, as both of these have both digital and analog outputs.But now, I am playing music from a HDMI source. I have not yet found an AV receiver that will pass HDMI audio out to analog outputs.The reason I need analog is because I have 2 slim analog amps to power 2 sets of outdoor speakers. This way I can control the volume of the patio speakers independently from the yard rock speakers.This tiny box let's me now play streaming music outside! I hooked it up to the optical output on my 7 year old receiver, and connected the RCA outputs from this box to the inputs on my amps.Then, in double checked the documentation to see how powerful of a USB power supply I needed. It didn't say anywhere! I had a 500ma, a 750ma, and a 1 amp. I figured I'd better be on the safe side and use the 1 amp one that came with my first smartphone!As for the sound, well, I can't tell any difference in the sound quality of what the digital signal is playing in my living room compared to what my Yamaha outdoor patio speakers are playing going through this and the inexpensive analog amps. There is a slight delay, although, I believe the delay was always present when using all analog connections in the past, and not caused by this FiiO box.I hope this little FiiO box lasts a long time, as it is doing a great job! Great purchase. Oh, the build quality send very good too!

### ⭐⭐⭐⭐ Good utility solution
*by J***B on June 3, 2021*

My Apple TV doesn't have audio out apart from HDMI and I wanted to connect my TV to my analog stereo system. So I had to use the optical output of the TV. This little box worked well and was light enough to simply hang from my preamp's RCA jacks behind my equipment without taking up any space. And once it's connected there is no reason to ever touch it again.Sound quality is OK... certainly acceptable for TV viewing. Although I didn't hear anything necessarily bad with this unit, I know it doesn't measure the greatest, etc.I changed my setup around where I no longer need to use it; but I am happy to keep it for whenever a similar need arises in the future. It's a good tool to have.
