Optical audio connections
 

Hi,

I'm about to move house and the new property requires a complete
rerwire, so I plan to take the opportunity to install audio and video
cabling.

My questions a

Is there any literature available on fibre for audio? I would like to
gain some understanding of it - light levels both xmit & rx.
I understand that the optical connectors are known as TOS Link -
correct? And are there dongles available to interface between these
fibre connectors and SC/PC or LC connectors?
Are there advantages to be gained in using optical vice coax?
Is Cat5 or Cat6 used in audio? I will be installing structured cabling
for computing - is it worth installing extra runs for audio etc?

Cat 5 is indeed used for audio, it's also used for analogue video (balanced
110 ohm) and works very well. Personally I wouldn't bother with optical, I'd
just use Cat 5 cable, it'll handle everything you need.

** Better go figure what "audio" is some day - pal.

Pal - is that a term of endearment that you use to try and makes
friends? I guess you've already found out that it doesne't work, hence
the reason you hear the term "Billy no mates" ring in your ears so
often

Well Phil, I can tell you what I have figured out, something many
others already knew, that you are an arsewipe and an oxygen thief.

I suggest you crawl back into your dingo infested **** pit and do the

Shielding is unnecessary for line-level balanced audio. Ever heard of "Music
Circuits"? In the pre-digital days these carried baseband audio from studios
to transmitters, or from OBs to studios, often over hundreds of miles. They
were routed over what was, basically, telephone cable. The only difference
was that more care was taken to get the balance accurate, but they were
unshielded.

Unshielded, cat 5 is garbage.

I have a good deal of experience using Cat 5 for balanced line-level audio,
and I assure you it works a treat.

Absolutely. In studio complexes it was common to have low and high level
tie lines. The only difference was the low level ones were screened. Of
course our colonial 'friend' probably thinks balanced circuits are only
for mics, where you need the screen for the phantom power.

Unshielded, cat 5 is garbage.

I have a good deal of experience using Cat 5 for balanced line-level

I'd got 10pair ordinary telephone cable feeding audio round here and
there's no interference or crosstalk problems at all. Of course it was
done long before Cat5 existed. ;-)

Hi,

I'm about to move house and the new property requires a
complete rewire, so I plan to take the opportunity to
install audio and video cabling.

I added some data wiring to my house when we did some major remodeling a few
years back.

I used this kind of cable:

Belden 7878A

It includes 2-RG6, 2-CAT5, and 2 fiber

I consider the fiber to be a future expansion type thing, as its termination
costs are still pretty steep for short runs.

I suggest you go back to school. Balancing is crucial to rejecting magnetic
interference, twisting the wires is just a way of ensuring good balance by
making the two conductors as equal as possible in terms of their position
within the magnetic field and with respect to ground. Accurate impedence
balance to earth at each end of the line is also important. Co-ax does not
reject magnetic interference. Balancing is also effective against
capacitively coupled interference and RF pick-up. Where RF is a major
problem a low-pass filter between the line and the receiving amplifier may
be necessary, as it would be with a co-axial line.

** A un-twisted pair mic line is a ** loop receiver** - it picks up
external magnetic ( ie AC hum ) fields just beautifully and feeds them to
the pre-amp input in differential mode.

Same as the wanted signal from the mic.

Hmmmmmmmmmmmmmmm....

Co-ax does not reject magnetic interference.


** Fraid it does and very well too.

I realise this is not a very well known fact, so you had better go look it
up.

Generally, it outperforms twisted pair cable in this respect.

Never head of "quad core" mic cable ?

Look that up too - while you are back in hell.


Balancing is also effective against capacitively coupled interference and
RF pick-up.


** Good shielding defeats both of them.

Balancing has no effect on RF injection or the demodulation of same.


Where RF is a major problem a low-pass filter between the line and the
receiving amplifier may be necessary, as it would be with a co-axial line.


** RF energy will not enter a well shielded co-ax cable from the outside -
it just travels along the screen and should then disappear to ground at the
input socket.

Same goes for a well screened mic cable.

You really don't know a single thing do you ?.

That's why you dish out all that crap advice you do.

Agreed. If anybody doing practical audio know about interference with signal
lines, its the car audio guys. This is the context from which I draw some of
this wisdom about the slender benefits of shielding.

While they often don't know what they are doing and this is yet another
example of it, some high end audio guys are using unshielded twisted pair
for line-level interconnects as well. The point being that their mistake is
believing that it helps. It isn't nearly the disaster that some people would
have you believe.
