200ohm input impedance
« on: February 08, 2007, 08:35:19 pm »

Hi Oliver,

I have several tube and transitor preamps from DDR, and almost all of them have a input impedance of 200 ohms. I think this is suitable for 50 ohms microphones, but how to proper interfacing with modern mics that whant to see around 2K input impedances? Maybe just using a resistive balanced network (2Kohms-->50ohms)in front at the cost of some signal loss? other solutions?

Thanks!

Most of the GDR/DDR RFT audio devices you can change the impedane via an inside tap....
If they do not have a tap a tap is the easiest way, or a new input would be the best solution.
