[QUOTE="Kevin Graf, post: 138569, member: 1897"] Re: Educate me: AES cabling The Rob Timmerman post #28 is the correct answer. Although I have an nit to pick about: [I]"the maximum length for something to be electrically short is 1/10 the wavelength" [/I]In my view it's about ¼ to ½ wavelength.So in a transmission line system, if the output stage, the interconnect cable and the input stage all have the same characteristic impedance, then the system will appear to be an infinity long cable.[I] (that is no reflections) [/I]Note that at audio frequencies (or under 100kHz) a cable does not have a single characteristic impedance, as the impedance will change with frequency.
