the idea is to run an eight-way symmetric audio

pairs and an outer foil shield as well) along with 4x cat5 s/stp
cables carrying 10/100/1000baseTX ethernet in the same cable duct
over a length of about 15-20 meters.
will this lead to problems in the audio signal?
Twisted pair ethernet is a balanced signal so should radiate little. If
your audio system is balanced too that will help.
With three shields between the audio and the ethernet twisted pair I
doubt if you'll experience problems. You don't mention whether the audio
cable will be carrying microphone signals or only line level - that
makes a big difference! If you're really paranoid you could use star-quad
audio cable. That has
four cores instead of two and much better inference rejection than
twisted pair.
hmm. i wonder how that works? anyway, four-core cables are probably
too expensive for me.
