Cat 6 for internal amp wiring

[Alex from Oz]

G'day,

I want to re-wire the internals of my amp using Cat 6.
Should I use the tightly twisting pairs for line level and the looser twisted pairs for the power output? Other suggestions?

Cheers,

Alex

OK, I plan to strip the outer sheath, separate the four twisted pairs and run those in place of hook up wire. One of tightly twisted pairs would be for line level and one of the more relaxed twisted pairs I would use for the output.

Does it make a difference how tightly twisted the wires are? Or does it make no difference?

Cheers,

Alex

only to replace other twisted pairs though
cat 5 cheaper

[Alex from Oz]

Yes, I built the amp myself from a kit so the twisted pairs of hook up wire that I used will be replaced by the Cat 6.
Seems like no one is telling me it's a bad idea, so I'll take it as a green light.

Cheers,

how well this is going to work depends on the speed of your cd player ..... or turn table .... if its 10mbps you use cat 5 anything higher will have to be cat 6


:: :


does any of the above sound any reasonable to you ???? i presume not ...so here is the story


cat 5-6 cables might work in a healthy envirolment inside one amp helathy = properly grounded and sealed

but all these twisted cables for line level signal might present capacitance or inductance that is not good for line levels or audio signal ...

then again elctrically wise this will might work but eventhough signal might be twisted with ground but this will not prevent cross talk between two signals if the cable is not sealed or coaxial ...

it might work but use simply nice coaxials keep your ground rooting under the rules and will be just fine

cat 5-6 has nothing better to offer you next to a standard coax cable probaly will make things worst

happy regards sakis

TBH i would have to say this is a bad idea. Small signal connections should be made with good screened cable. Speaker connections should be made with OFC cable of an appropriate gauge.

CAT6 (or CAT5 for that matter) is neither of those... it is designed to be used with balanced signals where overall capacitance must be minimised for long runs.

cat 5 is rated to 100mbps
cat 6 is overkill
check out EIA/TIA specs

it'll work fine to replace other twisted pairs.
not as good as coax. but fine where you would use twisted pair.

all 4 pair in the cable will work
they're twisted different to prevent crosstalk in the cable

Some of us refuse to use coax because we want solid-core wires in the signal path.

Hence I would say teflon-coated Cat5/6 twisted pairs will be just fine for signal wiring. But of course, keep the input tp separate from the output tp.

However, what would be better IMO (if you like to go to extremes ) is a couple of stands of solid-core, teflon-coated 26g for 'signal' twisted around a solid-core, teflon-coated 22g wire for 'ground'.

Andy

your set up will work only in very healthy areas were absolutelly no EMI of any form is present .... Unless ftp sealed cable is used with the ground connected properly

also only if things are kept very simple inside any device cause crosstalk will totally terible if more than one line is present

not to mention that if termination is very low this will behave very microphonic ....

if this type of topology had any chances to work be sure that some manufacturer will used in the past ...but so far never see that

all this was ment as a joke .... ...i dont really get your point ....
