ProtoDAC TDA1387 X8 project

[Tim Curtis]

Hi.
Does anyone know where I can buy Protodac Kit in Europe . I tried to buy one from Ebay but it come from England and now it is stuck on Romanian post office for some time and probably it will be returned.

Are you talking about the kit from @hifinet, the creator of ProtoDAC? These are out of stock.

Maybe I can find to buy the PCB , 40 pin GPIO header and TDA1387 X8 module . I don't need the caps, resistors and RCA.

I received my JLS I2SoverUSB_FIO card this week and am looking to use one of my ProtoDACs as a standalone USB input dac. Most of the installation seems very simple with good instructions.

I need to select a configuration for four jumpers to match the needs of the ProtoDAC, and the list of choices does not explicitly match what I have learned about the most basic MoOde  player I2S description (basic 'HifiBerry' passive dac without masterclock). The basic I2S configuration (J3-J6 open) and the TDA1541 in I2S mode in 32-bit frame (J3 open, J4 closed, J5-J6 open) look to be the best bets.

I'm likely being too cautious, so I thought I'd ask before just trying them. Help Most Welcome

Thanks,

Skip

Perhaps over on the DIY-Audio forum user Markw4 seems to be well versed in the operation of the JLS I2SoverUSB devices.

Hello - a little late to the ProtoDAC party but took the plunge and bought an assembled one from eBay (I'm not a hardware guy!). Anyway, all was well for the first week but now I'm experiencing distortion through both channels - can still hear the music but with a fuzzy static noise. Tried changing cables, etc., but to no avail. Had a quick look through this thread and it was mentioned that distortion in both channels could indicate some issues with the i2s soldering. Is there anything else I should be checking? Regards

The distortion noise is actually only coming from the right channel, so I would guess there is an issue with the RCA connector or solder around it?
