Hi,

My PC is quite far from the receiver and the cable would be app. 100ft long. I'm planning to use a regular stereo connection (the type with red and white rca). Just wondering if anyone has used such a long connection and if it's all right to do so. Or if there are any concerns or risks, what are they.

Thanks for your inputs.

You'd likely be o.k., but only if the cable you use is very good.

A better choice is to use baluns at each end. These convert BAlance to UNbalance (BALUN) and vice versa. Then you can run sheilded balanced microphone cable the distance.

This is the pro type of microphone cable you see on mic's that have 2 prongs and a sheild. They are also called XLR connectors. They are used at live venues where the equipment may be hundreds of feet apart.

This will be more expensive, but will be more noise imune.

If it is available, digital audio may be a better option. Optical cable for that length will be expensive and difficult to find. RG6 and a couple of patch cables will do the job for coax digital. You will need to be wary of ground loops on any connection that has an electrical ground (RCA or coax.) You might also want to consider TCP/IP networking using a digital media player at the receiver end.
