FiiO D03K Coaxial/Optical DAC Digital Analog Converter

The FiiO D3 DAC Coaxial/Optical to R/L Audio Converter is a high-quality option for taking devices that have no analog outputs, such as many modern televisions, and pairing them with stereo equipment that that lacks digital inputs. It also works as a modern and cost-effective upgrade for aging CD players with digital outputs.

• Power supply: 5 VDC via mini-USB connector, power supply included
• Output power: 1.6V
• Frequency response: 20-20,000 Hz
• Signal to noise ratio: ≥95 dB

• Total harmonic distortion: <0.008%
• Dimensions (L x W x H): 2.46" x 1.96" x 0.84"

Note: The digital input signal format for this DAC convertor is PCM. The ability to use this DAC device with a television to convert the digital audio output to analog audio is specific to the television. Check your television user manual to see if the S/PDIF output can be changed from Dolby Digital to PCM.

FiiO D03K Coaxial/Optical DAC Digital Analog Converter
FiiO D03K Coaxial/Optical DAC Digital Analog Converter is rated 4.9231 out of 5 by 13.
Rated 5 out of 5 by from Apple TV to Marantz SR7007 Amplifier.I found that my Marantz SR7007 Amplifier required Analog Audio as input signals for Zone 2 & 3. Therefore, while my Apple TV provided great audio to my main zone (Zone 1), Zones 2 & 3 were quiet. Therefore, I used the FIIO DAC along with a "Toslink Digital Optical Audio Cable 3 ft." to provide the separate analog signal to the SR7007 amp. Works great!!!

Rated 5 out of 5 by from Works with Large TV SetsI have a 92 inch Mitsubishi TV that I wanted to connect to a powered mixer and stage speakers for big sound . This device made it possible as the only audio output was digital coaxial . Thanks to this product I was able to do what I wanted and the results were very impressive !

Rated 5 out of 5 by from Optical to Analog AudioMy new Samsung Smart TV has only digital outputs for auxillary audio. And as most everyone knows, the native audio on modern thin flatscreens sucks.so you need some outboard sound repro. My Sherwood 100W per side receiver and 2.1 Polk and Yamaha speakers - already on hand - are fine for this application. But the 4503 Sherwood has only analog inputs, so this little converter is perfect for converting the digital audio - I use optical - to analog. Works just fine, makes a huge difference in the Pandora playback. Clarity and dynamic range are acceptable and marked improvements over the native speakers.

Rated 5 out of 5 by from EffectiveSolves the problem of getting good audio from the modern "skinny" flat screen TV. Our new Samsumg plasma has only digital audio out. My receiver, though new, has only analog stereo inputs. Solution - this little D to A converter that gives me a left/right analog audio output. A bonus is that the clarity and dynamic range are definitely better than taking the analog audio feed off the satellite receiver.

Rated 5 out of 5 by from worked perfectlymy new blueray player only has HDMI and optical outputs and I needed an analog feed to the amplifier I use for the house's ambient sound speakers. I used the 180-964 splitter to provide two optical feeds, one to the amplifier in the family room and one to this converter. Bingo, can play disks and stream content throughout the house. Small enough to just set behind the equipment in the cabinet, worked perfectly and reasonably priced. What's not to like about that?

How do you connect this to the digital source? I have an LG TV and the digital output is an odd shape, covered with clear plastic; it is not clear how to connect this to the TV. I wish to connect a sound bar.

Asked by: Mary1955
It sounds like you are referring to a TOSLINK type of connection. That is an optical output. You would remove the cover on the D to A converter where it says OPTICAL IN, and insert a standard optical cable. If using a new cable, make sure that you remove any plastic covers that may be protecting the fiber optic tip.
