It is ideal for interfacing between modern digital audio/video devices with analog amplifiers, self-powered speakers, or wireless headphones. The D3 (D03K) works with any audio source with an optical (Toslink) or coaxial digital output and is famous for its incredible quality and reliability. Here are just a few of the devices supported: Digital TVs and HDTVs CD, DVD, Blu-Ray players Digital media streamers and players Game consoles Satellite/Cable receivers and DVRs AV Receivers and Integrated Amplifiers Feature Highlights Built-in high-performance phase-locked loop (PLL) Ultra low jitter digital receiver Supports up to 192KHz/24bit audio signal Optical and coaxial inputs with selection switch 2 channel standard stereo RCA output 3.5mm stereo mini-jack for use with wireless headphones Indicator for digital receiving status MINI USB power supply port Specifications Power supply: USB 5V (Not Included) Audio Signal Output: 1.6V Frequency Response: 20Hz~20KHz S/N Ratio: >90dB Crosstalk: 75dB THD: <0.01%(10mW) Size: 61.6mm×49.1mm×21mm Weight: 50g

Review: Good for backup pc audio - Worked great when my case's front panel audio stopped working except for a bit of static when the pc was off but that could just be the motherboard's spdif port.
Review: I'm a bit stunned with this little Fiio DAC - a bit unbelievable for me (in a good way)... - Wow - now where do I even begin with this one? Received this little FiiO D03K DAC the other day. I got it to use with my video system on the first floor. I previously was using a no-name small DAC (about the same size as this FiiO D03K) and although it did the trick for what I wanted, I knew there had to be something better out there at the same size and price level. Because I have expensive and better DACs that I use with my reference sound system located on the 2nd floor, I happened to see this FiiO D03K DAC on desertcart. I know the FiiO name well, as I have happen to have one of their top-of-the-line reference quality DAC's, so my interest was piqued and I ordered one. When it arrived I immediately connected it (I ordered the version that came without a power cord because I have tons of power supplies on hand). From the moment I began testing it out by watching movies with Hi Def content, I was stunned at how good it sounded. Then just for sh_t's and giggles, I took it upstairs and connected it to my audiophile reference audio system, and it was there that I realized this little thing punches far, far above its weight. All of a sudden I was getting reference quality sound - far better than one would expect of a small DAC costing less than $20. No way, I thought - but yes WAY!!! So folks, if you are short on cash, or if you need a small DAC that punches far, far above its weight, don't hesitate to get this FiiO D03K. I give it my highest recommendation based on it's ridiculously inexpensive price vs it's high audio performance capabilities. 5 stars was an easy given.

## 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.

### ⭐⭐⭐⭐ Works fine on new Sony
*by A***R on May 31, 2023*

For the kind of money we spent on the new Sony, they should have included their version of this little box, or made it available on request to those of us who connect TV sound to a home stereo system. The newest ATSC 3.0 sets do not have analog RCA phono outputs for audio, which is why you may need this box. Be careful selecting among brands by checking the Specifications of your television against what these boxes can decode and convert.
