thanks to everyone who responded! after hearing your opinions, i think i'll go ahead and run both audio and cat5 in the same duct. i will do the soldering myself - if i can get hold of a multicore with quad configuration for an affordable price, i'll try it. david's suggestion to use individual cables makes sense, but would require very large holes through the walls, so i'll go with a multicore instead. the audio cable will run between two xlr breakout boxes, so the loom and shielding problem david hinted at will not be an issue. i'll let you know how/if it works out eventually... best, j?rn Joern Nettingsmeier wrote: > hi everyone! > > > we are moving houses in a month, and i'm planning to install some decent > cabling thoughout our new flat. begone, ye maze of twisty little cables > all alike :) > > the idea is to run an eight-way symmetric audio multicore (shielded > 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? > > my naive hope is that since all garbage radiating from the ethernet will > be well outside the audible range it might be ok. but then there's > always the chance of something demodulating it into the 20-20k range... > > does anyone here have experience with such a setup? > > any hints, success and/or horror stories welcome. > > > j?rn > > > > -- "I never use EQ, never, never, never.
