SPDIF taps (was ...we remember.)

[Bob Schrum]

Hey Magnus, I'm trying to do the same to my Denon DCD425.  Does anyone on this
list have any info on where to tap off the SPDIF signal among the following
chips?

    Sony CXD2500BQ, CXA1372AQ, CXA1571M, CXP82316
    Burr-Brown PCM1712U

I suspect the IC in question is the 2500.  I haven't yet found a local tech
friendly enough to get a look at the service manual (they just want to charge me
$100+ to do the mod themselves) and Denon's pretty tight about documentation.

Also, is anyone aware of any mail or web-based forums for audio DIY where I
could also pose this question without enduring serious discussions of $950
uni-directional orthogonally-crystalline double-shielded frequency-compensated
paradigm-aligned 96-bit twisted-pair digital optical cables, striped with a
green Magic Marker?  Y'know, just like this list--real electronics without the
mythical nonsense.

Thanks

--Bob

Hi!

All this talk about SPDIF makes me recall one of the more crude SPDIF
taps I have seen and it happends to be the case that I did it and
still has it around...

It is fairly well known (at least to me ;) that most CD-player
chip-sets have support for SPDIF and that only a few passive
components and a contact is needed. Well, as I was looking at the
service manual for my Technics CD-player I could easilly locate the
pin where the output where... so I opened it up and solderd a yellow
wire onto the pin, it sticks out of a crack in the front that allready
where there.. to use one has to take the ground reference from the
earphone jack... very crude but it is enought to get the bits falling
out on the box... so now I walk around with a CD player with a
mysterious yellow wire sticking out, and only you guys know what it is
for ;)

Cheers,
Magnus
