50 vs 75 ohm cable for interconnects? (1 Viewer)

[Chris L]

Looking at this website:

http://www.bus.ucf.edu/cwhite/theater/diycable.htm

It looks like he is suggesting a 75 ohm cable Canare LV-77S for audio interconnects. Aren't audio cables 50 ohms? I think this would cause reflections or signal degradation.

Thanks!

Video cables are 75 ohms and audio cables can vary from 50 ohms to over 100 (I think 200 or 300 - forget). Jenving's site I put in the other thread has some good info too (under FAQ):

75 ohm can be used for audio (actually any shielded cable can). The degradation is only a problem for video, when you try to lose 50 ohm instead of 75 ohm.
