FRC analog input RC filter values

I Know this has been mentioned on the forum before but, I can't find it. What are the resistor and capacitor values that are used for the analog input low pass filter? Isn't it set for 400Hz ? Can any one help or point me to a source?
Thanks

Re: FRC analog input RC filter values

I found a schematic on IFI's website. The resistor and cap are 1K and 0.047uF, respectively.

If I recall, the cutoff frequency is 1/(2*pi*R*C). That puts it at 3.4kHz.

Re: FRC analog input RC filter values

out of curiosity, what are you hooking up that you are concerned about bandwidth?
