If you look at PRR's current-feedback schemo, some would trace a direct line from input to input via silicon and say there's no resistors in the signal path and other would say that "everything is in the signal path". Or if you use a THAT 1512, there's only silicon but there are silicon resistors.sodderboy said:The Cloudlifter claims no caps, transformers, or resistors in the audio path, so it's only silicon?
That's a limitation due to phantom powering, but with the purely resistive nature of the source impedance it impacts only the max output level. I believe (I don't have the schemo) that the other performance factors are not altered when the load impedance is lower than 3k. Same situation with transformerless phantom-powered mics.And their optimal load impedance is 3K. That's quite high for most pre's which don't go much above 1K5.
Long cable runs are just a fact of life; I don't think anybody would use long cables for any other reason than necessity.I do not like long mic lines out of personal preference, but have no problems integrating runs over 400 feet when given no choice, either with splitters at the front end or not.
It is debatable; in terms of noise, the actual level is THE most important factor. Betweeen a super-LN pre (Grace, Green River...) and a sub-par one (Brick, TL Audio...) there's only about 5dB difference in EIN, so in the end level is the determining parameter that defines the noise performance. And the greatest cable won't make a bad pre sound good; and the greatest preamp won't compensate for poor cable... Audio degradation is a cumulative problem, all the elements must contribute to the overall performance.Of importance is not mic level but cable choice and mic pre quality.
A Cloudlifter won't make a Soundcraft or Mackie, or Neve or whatever sound better. It may make a mic+cable+preamp combination perform better; the reason would be that there is a mismatch in the combo originally. Typically the microphone would see inadequate loading and the mic pre would see inappropriate source impedance, then the addition of an active buffer would sort out the problem.If something like this makes a Soundcraft or Mackie sound better, great!
