Roland KC-550 Input Impedance?

    Has anybody used one of these? I've been googling around hand haven't been able to find anything. I know it's a keyboard amp but I will need to use one of these soon and I'm wondering if I'm going to need something to act as an impedance buffer for my Realist. I'm wondering about the 4 quarter-inch inputs, not the XLR input.

    I'd say you can count on it. Given its intended purpose, it wouldn't make sense for Roland to engineer it with piezo-friendly inputs.

    I use an Fdeck pre with a Roland KC300 sometimes and it works just fine.

    Since you mentioned it, do you happen to know the output impedance of the Fdeck? The input impedance is 1 Mega-ohm, correct?
     
  5. Look at the schematic which is freely available from Francis Deck.

    The input impedance is 10 MOhm and the output impedance 10KOhm for Version II and (more or less) zero Ohms for Version I (I think, but probably about 2 KOhms). At least low enough for a line input, not low enough for a mic input, but the voltage would be too high for a mic input anyway, so this doesn't matter.
