The Outlaw PCA's are analog audio cables: that means they can be used for any analog audio connection (2.0 analog from source to receiver, 7.1 analog from source to receiver, pre-amp outputs to power amps, or output to a subwoofer). Component video, composite video, and coaxial digital all require a 75ohm connector - which you don't necessarily get with an analog audio cable (because it isn't required). For those three applications, a cable such as Outlaw's PSC is recommended. If you have a cable that was made for use with component video, composite video, and coaxial digital, it can be used for analog audio. I would not recommend doing the opposite, however.
