Elekit USB-DAC MODULE [ PS-3249R ]

Recommended Posts

http://www.elekit.co.jp/en/product/PS-3249R

 

I'm planning on building my first DIY tube amp kit (the Elekit TU8200)

One of the options is adding a built in DAC module.

specs:

- Power supply system: USB bus power
(Possible to modify to self-power system to supply external power)
- Operation system: Windows XP or higher, Mac OS X or higher
- USB: 1.1 or 2.0
- Sampling rate: 32kHz, 44.1kHz, 48kHz
- DAC resolution: 16bit
- Output distortion rate: 0.014% (USB bus power)
- Frequency response: 10Hz-22.5kHz (1kHz)
- PCB size: 97x45mm

 

I'm wondering if the specs of this module are good enough and futureproof.

 

Also, it is listed as compatible with Windows OS and Mac OS, but I'm running Linux (Ubuntu Studio). Is linux going to work with this module?

I don't know but would be highly surprised if it didn't work better.  Been using GNU/Linux, solely, for ~25 years.  The other stuff is toy-like in comparison.

Okay, I looked at the product page.  All they're saying re supported OS is that the device presents itself as an USB audio module.  If that's true then no worries with your Ubuntu.  Worst case would be you'd have to add a definition to a text file and recompile something.  Very easy to do but quite unlikely in this case.  Quite quite.

I have some usb audio intedfaces that work fine in my DAW on linux. All the inputs and outputs. Most don't work with usb3, but usb2 devices are usually no problem at all. That will get better as time passes, of course.

Yeah, like I said in part, if the device ID has not yet been included in the library files, you can do that yourself and give a heads up to the maintainer(s), or you can just let them know and wait a day or two while they take care of it for you.

So ok for Linux.

 

And what about

- Sampling rate: 32kHz, 44.1kHz, 48kHz
- DAC resolution: 16bit

 

Is that good enough?

16 bits is a bit shallow in terms of capability these days, but in my experience and opinion it's entirely sufficient.

 

Depending on what you plan to feed it, it should do well.  You may have to run higher bit-depth stuff through audacity first unless that card will take care of that on its own.  Can you find the maker's documentation?

I don't quite get the 22.5kHz top end. Most newer dac designs are higher to prevent having to use extreme brickwall filters on the top end which have tended to be messy. Proof is in the listening, though.

This is not very good compared to newer DACs.  Should be at least a Sampling rate of 96kHz and resolution of 24bit.  192kHz or 384kHz would be subjective better depending on what you are using for input.

I agree with the last three posts. You’d be better off with a separate DAC. If you start with an inexpensive one you can always upgrade, which won’t be an option with the built-in DAC.

Agreed, buying anything that locks you into one solution and you can not upgrade a component as standards change is not cost effective  or a good idea.
