Digital Audio Cables

[Guest DSN]

Hello all and Happy Holidays,I would like to know if there is a maximum length for digital audio cables (coax or optical). I would like to connect my computer to my stereo system which is in another room. I would need 15-20 feet for cable to make a connection (under the floor)thank in advance-DSN

There probably is some finite limit, but I haven't reached it yet. I connect the SPDIF (coax) out from the PC to an in-wall cable that extends ~ 75' to my whole-house sound system receiver downstairs. Use RG-6 (quad shield) not RG-59. RG-6 is 18ga (vs. 22ga) and has better shielding. Technically, your cable must be rated CL-2 or better if it is to be permanent in-wall. There is also a plenum rated cable for routing through duct. I haven't tried long-distance optical, but I don't see why it wouldn't work either. I've always used coax because it is more common and easy to work with. I understand that Cat 5 UTP is also an excellent choice for digital audio but then you'll need to adapt to the correct connectors at either end.I have a DSL connection, so I find myself listening to internet radio more often than broadcast radio. Sometimes if I'm working around the house, I'll find a scanner site and listen to ATC while I work. Another neat trick is to play classical music and then have the ATC over the top of it. I suppose you could also set AI to 100% and listen to your virtual ATC!
