At what distance are you using the mics?  Here's the curves for a Beta58 at various distances:

Those Shure curves show proximity effect from cardiode patterns. The RE-20 is unique in that it has no proximity effect even though it's a cardiode pattern. That's what makes it a great kick drum mic, you move the mic around and the low end remains consistant.

The preamp in question is a 1066, which is indeed at 1200 ohms, but would this account for the low level?

Considering that the mic is wired for 150 ohms output, shouldn't it be able to cope with a 1200 ohm load?

I'm thinking maybe this is just how they are - unless someone tells me it's not the case.




Dan, I did not se this back then, but if this thing still bothers you(or anyone else), there is a simple solution:

RE20 is the same as PL20,the only difference beeing RE20 having a bit more open a reflector in front of the diaphragm. I have both and sonically they are identical too. They are factory-wired to 150ohms, but you can change that easily to 50ohms or 250ohms. I wired mine to 250ohms and have much higher level. Your 1200ohms preamp will handle it without a problem too.

Here is what to do: pull out the XLR and screw off the bolt holding the rear of the mic to reveal the trafo-solderings. You will see the red wire on place, where it says 150ohms. Remove it and solder it to the place, where it says(guess what)250ohms. That`s all! Put the thing together and enjoy more level!

I would think that, although you will get more level going from 150 ohms to 250 ohms, you might loose a bit of low end punch with that impedance relationship. Over 1800 ohms would be a better input impedance for the 250 ohms of the mic.
