Rated 4 out of 5 by from Good valueVery versatile DAC. Decent SQ. Defiantly better than the audio output that comes with the MacBook Air. RCA out from this DAC is weak though. I wound not use it for my main source of audio but it is what it is and it makes me happy. Thank you PE.

DAC Digital to Analog Audio Converter Optical / Coaxial / USB

I have a TV that I think has the PCM output mentioned as being needed. Will I be able to plug headphones into the 3.5mm jack and receive sound without connecting to an amplifier or stereo system? If so, will the volume knob control the headphone volume?

Asked by: likitysplit

If all my pc has are usb port's, how do I get the audio signal out via the usb input on the dac. Will the pc recognize this device and send signal out ??

Asked by: sloatsburgbob
This DAC can connect to a PC using a standard USB cable and the Audio assigned to that USB port will be converted to analog audio out the RCA jacks of the DAC.

We bought our DAC less than a year ago but it's not working at all since we hooked to a new DirecTV Genie receiver.  Can you help us do some troubleshooting?  We've checked all cables and everything is connected properly so we're not sure what's wrong.

Asked by: CRaff
Your DirecTV Genie is likely in Dolby Digital mode and this DAC does not support Dolby Digital. Here are your options:Under set-up in the Genie, select audio and turn Dolby Digital OFF (page 88 of your Genie manual). This should put the Genie in PCM mode so it will work with the DAC.You might consider using a different DAC for your application; I recommend our 180-999. The 180-999 DAC is compatible with all popular multi-channel formats so it should work well for your application.

Can I use the DAC to play music on a USB flash drive through the RCA jacks into my stereo receiver? If not, what can I use to do this?

Asked by: RoyDalton
The USB input on this DAC can only be used for power or through a powered USB output, it will not accept any other type of input. The USB Media Card Reader below will accept a thumb driver or SD card and has a standard hard wired line level output.http://www.parts-express.com/mp3-usb-media-card-player-module-with-remote-control--320-350
