Digital to Analog Audio Converter Optical / Coaxial / USB is rated 4.4706 out of 5 by 17.
Rated 5 out of 5 by from Great Features, works great with new HD TVWe needed to use headphones with a new HDTV, that only had optical output, the unit works great, the video was very helpful,

Rated 5 out of 5 by from A simple component that works !I've had this DAC converter for two weeks and couldn't be more delighted. It simply does the job as advertised (via YouTube). I can "audio out" to my stereo AM FM receiver speakers and blast off. Great product, at a reasonable price. Get it, now.

Rated 5 out of 5 by from Great ProductI've had this DAC for over a year now and have been nothing but pleased with it. I've used it to connect my Apple TV to a stereo receiver as well as an X-Box to an integrated amplifier via optical digital output from both devices. The DAC has functioned perfectly and provides very good sound quality (clear highs, strong lows, smooth and detailed sound overall). I haven't used the other inputs (USB, coax) so I can't comment on them. Also, I've only rarely used the headphone output, but the few times I have, it sounded fine and drove various headphone models perfectly well. The only minor quibble I have is with the input selector switch which is tiny and chintzy. If I were going to change among inputs frequently, I'd be concerned about its durability. Overall, this inexpensive DAC has worked perfectly for me and surpassed my expectations for sound quality.

Rated 4 out of 5 by from Decent unitIf you're not in the market to buy an expensive DAC (i.e. audioengine or Cambridge Audio DacMagic) but still want quality sound and simple connectivity this should be your piece.

Rated 5 out of 5 by from Digital to Analog Audio Converter Optical / Coaxial / USBI recently purchased a new HD TV. Much to my dismay, it had no analog output of any kind. Only Digital. My wireless head phones would not interface with a digital device. The Digital to Analog Audio Converter Optical / Coaxial / USB saved the day. I can now crank up the volume wearing my head phones and not disturb the rest of the family. Thanks again Parts Express for having the right product at a great price!Timothy Brewer

will this work with 5.1 optical out?

I have a Panasonic LCD with digital audio our and want to hook up wireless headphones for my grandfather (hard of hearing). Will this work?? I'm hopeful...thank you
Asked by: wildapple
This converter will only work with an output configured for PCM (two channel) digital output. Most TVs can be set up this way through their audio menus. If in doubt, consult the manufacturer of your television.

Does the optical cable come with this?

I want to be sure the connecting optical cable comes with this unit?
Asked by: Michwarm8
This unit does not include the optical audio cable. I have linked our most popular optical audio cable below.

Does the volume knob affect only the headphone jack?

In the purist sense, a DAC would just pass the digital stream and the DAC would be connected to an amp or preamp. Can this DAC be used to output a digital stream from a computer e.g. for internet radio, while bypassing the volume knob?
Asked by: aseltzer
Yes the volume knob only controls the headphone output.

Does anyone know if this DAC works asynchronously?

Does this DAC work asynchronously whereby it controls the flow of data from the PC over USB i.e. to eliminate or reduce jitter, or is it merely an interface designed to output analog data to RCA from a USB or SPDIF source?
Asked by: aseltzer
The manufacturer lists it as merely an interface designed to output analog data to RCA from a USB or SPDIF source.

What is the voltage out and frequency response of both the analog outputs and the headphone output? Also what is the output impedence of both?

Asked by: AVGuru
The output impedance of the 3.5mm jack is 600 ohms, output impedance of the RCA output is 10,000 ohms as stated in the specifications. The output voltage of the 3.5mm jack is approximately 1.3 volts, and the output voltage of the RCA jacks is 1.35 volts as stated in the specifications. Unfortunately, we do not have any specifications available on frequency response, nor do I have the facilities to measure such.

I didn't notice a signal to noise ratio. Are there any specs for that?

Asked by: Thor
I can't find any specs on that, but it operates nearly silently on my equipment.
