Re-Life to D1 PCM63 DAC

Filed under: DAC,Gallery — Spencer @ 2:12 pm

With the work of 1 year away from home, I am back to Singapore and thus able to be with my old hobbies – DIY audio. During this time, I was approached by a DIYer about the modification of the D1V2 (http://www.fetaudio.com/archives/23) board to use USB input for network audio. After some discussion, the DIYer is able to make it work and here I share the details of the modifications of the USB to PCM63 DAC with permission. I keep all the original text of the modifications and only added few comments in the text.

– concerning the 24 bits mod. Here find a link to a photo i did. Instead to cut the PCB, solder a wire, i removed the P10 pin and soldered a wire from P10 to the jumper “GND”. Easier for me… http://www.homecinema-fr.com/forum/download/file.php?id=91284&mode=view

– i put a trigger in my casing. In this way, the DAC switch on automatically when my DIY preamp is on. I like it !

– i connected the GND of your DAC to the earth of the IEC through a 10R (in mine 18R because i was stock out….) 3W resistor. I don’t have any “humm” or any noise with this way

– an finally i put your name on my backplate. 😉

Hi! Spencer: My D1V3 complete. I order the kit in 2008.02 but 2009.09 start assembly. I use 4-PCM1702UK, DIR9001 and SM5842AP.
I buy 2 round transformers from Shenzhen, but when I do test the transformers all burnt ! so I buy 2 from Wha Fei. The FC 1000uf foot print bigger than the PCB. I make a out side power supply.
I go to Chaiwan a steel shop cut and bend the steel sheet (thickness 1mm) for the chassis.  I pay HKD100.00. Then I open the connector holes, brush paint.
The DAC is good sound more detail, compare to my DAC3 – PCM1732 with HDCD (from Taiwan DIYZONE.NET).
Thank you for provide this good kits and your help during my assembly.  I am an old man and have family work.  So take long time to complete the DAC.  David

Update on Dec 27, 2009: Spencer: I replaced the PCM63 to my D1 V3 make some adjustment . Today play music all day. The PCM63 is better bass and more detail. . Thank you . David
