Hi!

I have an idea and I'd like to hear your opinion about it: I'd like to
build digital speakers. That means that even the bus to the speakers in
is digitals. Making the signal analog will be done within the boxes.

Is there anyone selling such boxes? If not, what kind of bus would you
use? I'm not sure whether S/PDIF is the right thing for me because I
have to transport only one channel. And even if, I still need to split
the signal before going to the boxes and chips with are capable of
decoding the stream.

Any help appreciated,
Kevin

What are you attaching the speakers *TO*?

If you are talking about "computer speakers", there
are at least a few speakers out there that attach with
USB and perform the D/A conversion and amplification
within the speakers. I saw one the other day over at my
neighborhood "big box" discount store (Costco).

If you are talking about "hi-fi speakers" (in your living
room/home theater, etc.), there are likely speakers with
integrated digital inputs and amplifier(s), but you are
likely talking about high-end stuff at thousands of USD.

Actually, I know of few. The best examples are from Meridian's DSP
line. The overwhelming majority of high quality home loudspeakers are
completely analog.

Hi!

Thanks for your answer!
If you are talking about "hi-fi speakers" (in your living
room/home theater, etc.), there are likely speakers with
integrated digital inputs and amplifier(s), but you are
likely talking about high-end stuff at thousands of USD.
This comes quite near my idea. I just wanted to take a couple of good
active speakers(~300USD, don't know whether you'd call this good, but
the room to fill with sound is only 28 cubicmeters) , and put D/A-chips
inside to be able to connect them to my equipment. I have only digital
equipment, so it seemed a cool idea to me to have as less analog cable
as possible.

HAND,
Kevin

In the computer world there are speakers out there that attach with
USB and perform the D/A conversion and amplification within the speakers.

There are also speakers for example in professional monitor speaker
market with S/PDIF digital interface (for example GENELEC 2029A).

I'm not sure whether S/PDIF is the right thing for me because I
have to transport only one channel.

I think that S/PDIF is the right thing to use.
It is well standardized, there is wide selection of suitable
ICs for handling the signal, equipment with digital output
most often give this kind of signal output directly. etc.
S/PDIF sounds like a pretty good idea to me, even though
you only use half of it's bandwidth per speaker.

And even if, I still need to split
the signal before going to the boxes and chips with are capable of
decoding the stream.

You need the decoders in the boxes, that's for sure.

You don't need any fancy special splitter for going to both boxes.
Baically you can build the system in such way that you always
feed the same full stereo signal to both speakers, and the
speakers just pick up the channel you want to play out through
it and forger everything else coming in. You cna foe example
have two identical speakers with S/PDIF input and switch on the back
to selec which channel audio to play back (just set left speaker
to left channel and right speaker to right channel and things work).

For splitting the audio from one source to two speakers, you bascially
need some form of passive signal splitter or active splitter amplifier
that can run two outptu cables from one signal source.
Passive splitters will do if you don't have too lign cables or have
sensitive enough S/PDIF signal receivers to get slightly weaker
than normal signals. Passive splitter for coaxial S/PDIF if just
simply a tranformer with one primary coil and two secondary coils
(with slightly less turns than primary), that does the impedance
matching. Active solitter would be something quite similar to
a vidoe disribution amplifier or s/ODIF inut amplifier + two S/PDIF
driver circuits.

For optical Toslink interface, I quess that a simple optical signal
splitter would work well (I quess I have seem somethign like this for sale
somewhere quite cheaply).

Any help appreciated,
Kevin

Hopefullymy tips helped you.

Of course DRM wouldn't be possible if there was only analog music, but
the differences between a semi-digital and a completely digital world

Not saying that it would be an interesting experiment, but
you would be trading artifacts caused by your wiring for
artifacts caused by your home-made D/A converter.

to be able to connect them to my equipment. I have only
digital equipment, so it seemed a cool idea to me to
have as less analog cable as possible.

It is most likely cheaper (and most certainly easier)
to use good-quality (NOT "name brand" boutique) cable.

Not saying that it would be an interesting experiment, but
you would be trading artifacts caused by your wiring for
artifacts caused by your home-made D/A converter.

BTW: Most CD-ROM drives have a two pin output called digital-something.
Is this a S/PDIF output?

Yes, or at least it is supposed to be.

They often are S/PDIF-compatible signals but sometimes at CMOS voltage
levels.
