Default Chinese TDA1541 v4.0

Sorry, but I am a newbie, know little about DAC. I just bought this Chinese DAC 4 x TDA1541 in parallel. I just hooked up the transformer temporarily just to see if it works. My problem, is that it works when plugged in to my regular Marantz CD player, however, if I plug it in to the SPDIF output of my computer, I get terrible crackling sound. I know my computer is fine as I have another DAC using TDA1543 with DIR9001 and it works fine, however, it does not work with my new TDA1541 DAC, but works fine in my CD player, can someone please explain to me whats going on here? I like to get this DAC to work, as I like what I hear when using it in my CD player.

Please help..

Alex

I also have a TDA1543, with tube output stage and this one works for me, I actually like the sound of this DAC, but the TDA1541, when plugged into my CD player gives excellent sound though, very clean.

Thorsten used to call Raindrop "horrorshow!"

DAC build TDA1541A/SAA7220P/B *will take som time*




I also have a Raindrop DAC that has a funny SPDIF lock issue.


Using the the USB and optical SPDIF is fine, but when using the BNC SPDIF I have to pull my cheater plug back a bit to break the ground connection ... and then it works fine !?!?!

This makes me think the SPDIF transformer is grounded on the wrong side or something ... you never know with Raindrop. I'll be trouble shooting it soon.



Yours sounds like more of an SPDIF audio format issue:

IMG_2224.jpg

On the back of his/her digital source select PCB is a push-button and two LEDs:

D1 D2 Format
on on 16/I2S
on off 24/I2S
off on 24left
off off 16right

I'm using 'on on 16/I2S' format to lock to the optical SPDIF out of a Musiland 01USD USB to SPDIF converter and regular CD files in .flac It's a NOS 1541 DAC using the WW8805 receiver; I also have the digital input select board.

(Once I fix the BNC SPDIF, I'll be able to select between 2-3 SPDIF sources)

Cheers,
Jeff

TBBK, could you say more about your problem?

I'm guessing the two LEDs in the front are for power and lock.

Does it power up?

Does it lock on to an SPDIF signal?

SPDIF coax or optical? Your DAC is more basic because it doesn't have any selector (I'm assuming the switch on the back is for power) for the digital input. So that means coax OR optical plugged in but NOT both plugged in at the same time.

Does it produce any sound?

Is the sound distorted or crackle?

I can hear the frustration in your post, don't worry dude, we'll fix this!

Cheers,
Jeff

Hi Jeff, Bad stuff from China.... A familiar place to be.... To bad someone on this side of the pond doesn't design a good 1541 dac board. I'd be in line to buy one. Thanks again for posting on the other thread. I will probably do as Thorsten suggests with the Veroboard. It's hard to find the key posts when they are hundreds of pages long. Dave

Audiolapdance,

Power up nope.
Change the 12v, measure voltage on dir9001.
No sound at al LEDs dead.

Need a schematic, does anyone knows the manufacture of this dac
I have wait for 5 weeks to get this, and I'm sure I'm not the only one that's has these problems...
