AudioSector-chip amp kits, dacs, chassis

[Peter Daniel]

At least 200 sets of that DAC has been sold already, and I'm not aware of anybody having a similar problem. It's either player, or a bad chip. I tried variety of transports and there was always compatibility.

Try to increase the value of R6 to let's say 400R and see if this changes anything, although I don't think it would matter.

What are you using for a preamp?

Thanks for those pictures, mine looks just the same

I tried 500ohms (the closest I have) there and it made no difference :{

I am using it plugged into a set of JBL active computer speakers at the moment but I also tried it with my headphone amplifier ( http://www.amb.org/audio/mmm/ )

I have to humbly apologise and hang my head in shame....it works and I have been an idiot.

I wondered when building what the ---J--- marking meant on the topside of the CS8412. Rather than figure it out I thought I'd come back to it.

Suffice to say now I realise it means jumper and have inserted the wire, the dac works fine

I was studying the pictures joint for joint for about the 50th time when I realised yours has a jumper in there. I now have to put the line driver back in and tidy up the mess I have made

At least you know what to tell the next dummie who complains of the same thing

Happy new year!

Magsy does it now work with coax out?

maybe i made a mistake with mine hmm

does anyone have problems with coax out?

peter should it work with coax out?

whats the Difference between the two?


coax out
digital out


cheers

[Magsy]

Karma,

Coax and digital are the same thing.

Coaxial = a cabled connection (not an optical one)

Probably your players have it labeled differently, some of my stuff says coax, some digital and some spdif.

Now I have added the jumper everything works, my soundcards and the cheap dvd player.

Did you place this jumper?

[karma]

no my pcbs different.digital coax are the same hmm i guese ill need to take another look at mine


thanks.

[Magsy]

Peter, does this green dac invert phase like the gold?
If so I just swap rxp for rxn and vice versa correct?

Thanks

[Peter Daniel]

Yes, it is invertinging. Swapping those will adjust for correct phase (I do it between input driver and receiver).
