Ohm, a question please.

Could someone tell me in what circumstance I would want to change the output of my A-Designs mp-2 from 600 ohm to 10k? Thanks.

The answer is simple. If you're plugging your preamplifier into a quality studio console like an API or Neve, you want 600 ohms. If you are plugging into a Tascam or other consumer piece of crap, you want 10,000 ohms. If it has a 600 ohm output, you are going to want to terminate that output with a 600 ohm resistor (in all actuality, 620 is more common) or into a 600 ohm input transformer. No amateur beginner crap will have that. They will all be at least 10,000 to 50,000 ohm inputs. The professional output will also be + 4 DBM. The consumer items will be somewhere around -10 DBu and really cannot handle professional studio line level stuff without overloading.

Lucid indicates that your unit has a XLR analog input connector and so it accepts higher line level balanced signals. If you are using that input connector I would suggest you switch your unit into 600 ohms. Your unit is designed to accept balanced studio line level inputs.

If you are using a 1/4 inch analog input (if that unit even has one), switch your unit to 10,000 ohms. It's that simple.
