[QUOTE="John Roberts, post: 89482, member: 126"] Re: Maximum analog snake length It depends... back in the day when pro interfaces were 600 ohm for line level, the capacitance would make more of a difference than modern gear that is generally designed to present lower source impedance. There is not a firm standard for line level source impedance. Most professional (expensive) gear will generally drive 600 ohm loads to decent level which requires output impedances a modest fraction of 600 ohms (i generally used 50-100 ohms build-outs in pro designs). Some lower cost (MI, semi-pro) gear to save the cost of high current output drivers, or to improve effectiveness of turn on transient clamping can use hundreds of ohms. I've seen low cost gear with source impedances as high as 1k. So the short answer is YMMV, and again "how does it sound?". With well designed professional gear, I would expect line level gear to deliver slightly better HF response than a simple microphone. Old legacy (600 ohm) or cheap semi-pro gear could deliver worse HF performance. JR [/QUOTE]
