[QUOTE="Bennett Prescott, post: 89395, member: 4"] Re: Maximum analog snake length Jason, There are a few issues here, none of which are likely to be significant at that snake length. 1) Transmission line reflections from unterminated cabling that approaches or exceeds 1/4 wavelength at the highest frequency of interest. However, in baseband audio this is easily a kilometer so unlikely to be a problem. 2) Increased loading from the resistance of that much cable making preamps behave funny, but a few hundred feet still shouldn't be an issue at the impedances likely present. 3) Capacitance acting as a LPF - this is the most likely problem. Easy to compensate for. While this length (430') is getting pretty long even in the arena audio world, it will depend on the actual capacitance of the cable used. Better cable has lower capacitance, and in fact AES digital rated cable will probably not care about that distance at all. [/QUOTE]
