Threshold input impedance ????


Does anybody know what is the imput impedance for a Threshold S450e usinf the balanced XLR connection?

Thanks,
Jose.

I do not know the exact number however I know that all Threshold series pre & amps were IGFET designs. Given this fact, the input impedance will be very high for both single-ended & XLR.
If your pre has a nominal output imp. of 600Ohms or something higher like 1 or 2Kohms, you should be just fine using the S450e, IMHO.
FWIW
Thanks for you reply. The reason behind my question is that I am planning on buying a pair of MIT balanced interconnects and they are input specific (Low/Medium/High) and I need to pick the right one. Here is how MIT devide them: low (5-50-kW), medium (40-100kW) or high (90-¥kW) .
