Non-Oversampling DAC

lucpes · 15th June 2004, 05:52 PM

Having run out of capacitors and since the ones from Farnell come in about an week I thought of taking some pics;

The PCB and the receiver/DAC is bought from here: http://www.rockna-line.com/diy/dac/dac.htm , and if anyone could answer this thread I would be eternally grateful!

And yes, dog hair and other dirt may get onto your PCB and mix with flux residue to form a nice combo if you're not careful

Is this supposed to be one of the best sounding D/A chips out there?

Two days work but still lots to do!

Looks nice. Does the Rockna DAC come with I/V stage, or do you have to order the separate output board from them.

I think the separate I/V stage is for existing CDPs/DACs (owner told me it's supposed to sound better than an opamp based one but I cannot comment on that as I did not want to rip apart my Marantz CD-94 to try that

)... the DAC PCB I have includes the I/V stage.

Is the ASRC section of the AD1892 bypassed?

Hello nice project!

What's the cost of that board?

Oh found it

The ASRC is set to 1:1 upsampling, so output is clocked after low-jitter master clock. The cost of the board is 29 euro.

How do you set the ASRC to 1:1 upsampling?
Thanks
