So I am trying to get an understanding of impedance, and how it affects the audio chain.
Someone mentioned somewhere, that the Axe3 outputs are 600ohms. If that's the case, it made me wonder how that makes sense?
Usually the rule of thumb states, that you want the impedance load of what you connect your source into, to be at least 10 times higher than your source impedance. In the Axe3 case, that would then be > 6K ohms.
But considering that the Axe is basically built to connect to the mic-pres of a mixerboard or sound card, and these often "only" have a load impedance of 1,5K - 3K ohm (which is usually sufficient for microphones, as they are about 50 - 200ohms output impedance). My big analogue Amek console from 1993 for example, have a 1,5K ohms load, on the Mic-pre's.
I am sure there is a very good reason for these specifications, and that it all makes sense. But perhaps someone can chime in on, what I am overlooking here?
