Hi Folks,

I was wondering if anyone knew the answer to this question. Can I
take the optical digital output from one band and run it into the
optical digital of another. I imagine that the audio component mighti
be standard, but any device control would be proprietary. Does anyone
have any firm knowledge about this?

Thanks,
Mark

Hi, just to check, if that being the case can I connect Sony CDX-C90
digital toslink out to Alpine PXA-H700 digital toslink in? Will it
work?

Please advice. Thanks. Regards. Vincent

Digital signals when using optical digital inputs/outputs are not
proprietary from brand to brand. They are compatible with any device
using optical digital as a connection. Most likely it is a Dolby Digital
or DTS signal. They are standard surround formats. Optical Digital can
carry regular stereo signal as well. It is a standard cable format.
Others like IP-Bus (Pioneer), or CE Net (Clarion), AI-Net (Alpine), etc.
are propietary formats, but optical digital is ABSOLUTELY, FOR CERTAIN,
MOST DEFINITELY not.

ADAT Lightpipe.


We are talking car audio here. Obviously.

Obviously? Are you sure we are only talking car audio? The OP may have
posted the same thing to several groups but did not crosspost as to maintain
usenet protocol. He never mentioned anything about car audio, only optical
digital. You must be careful when making blanket statements like
"ABSOLUTELY, FOR CERTAIN,
MOST DEFINITELY not."
Because there are obviously things that defy that.

I was thinking of something similar: the Pioneer P5000MP with the
Alpine PXA-H700. If Murphy rears his head, I could use the RCA's.

Thanks,
Mark

Well this is rec.audio.car. (so it is safe to asume)

the "absolutely,for certain most definetely" was just a play on what the
OP said: "does anyone have a FIRM knowledge...."


i know there isnt a be all end all answer.

but most optical digital devices ARE compatible with eachother. i
answered his question, that is all i think he wanted from anyone. dont
make this into a "thing" like everyone else does on r.a.c.

feel free to show examples of where my answer does not apply. i would
actually like to know for myself.

PS: relax.

If you knew that then why did you give an end all be all answer?

It is a "thing". If you would have said that most optical digital devices
are compatible then it would be fine, but you gave a this is the only way
and the only thing it is used for answer which was wrong. You gave the OP
only half correct information, which could be just as bad as outright wrong.
So, yes, most optical digital devices are compatible with each other. But
before laying down money on something double check, there are a few
companies that will use the same cable and jacks but encode it differently.
It is easier for a manufacture to use a cable system that already exists and
rewrite software rather than reinventing the wheel everytime.


PS: relax.

PS: I am relaxed. You gave a wrong answer and it was pointed out. Just be
wary of end all be all statements.

ADAT Lightpipe is becoming standard for a lot of things, What if you
could take (someday) ADAT lightpipe out of a head and pass through
amps, keeping all the speaker processing at the head and telling the
amp which signal to peel off?

Don't discredit technology, Car audio is a tad behind the rest of the
audio world, which suprises me. Seems now it's all about chrome
baskets and animated faces on headunits. BFD Keep your eyes on the
road.

Back in the day (I won't say how far back to protect my grey beard)
car audio was innovative, now it looks stupid and sounds no better.
Embrace technology, use an 8x8 lightpipe interface and get rid of
ground loops, I'm sure many here can find a use for hauling many
channels of audio down fiber.

Obviously, but it sure would be nice to blow 8 channels from your hu
back to your amps digitally. For the chosen few who want more than 2
channels of course.

It would be nice ... I remember in 1998 I had a Clarion setup that had
optical connections between the HU and cd changer and DSP. I always
wondered when I'd be able to go fiber all the way to the amp. Now I have a
whole new Alpine setup and still can't do fiber to the amps (though my amps
are old, I haven't seen new amps that do this) and have to deal with ground
loops and hated rca cables.
