CA9100 preamp bass filter specs?
« on: October 04, 2011, 12:22:26 AM »
Hi folks. What is the approximate low-end shelf of the bass filter in Church Audio's 9100 preamp? I'm looking for the corner freq and slope of the shelf. Thanks much,
Chris.

According to Chris (copied from an earlier post):
The high pass filter is in the input stage of the preamp and thus no issues with what ever recorder its connected to.

Therefore Chris' HPF does a constant rolloff no matter what recorder is used. This is much better than the system used by Sound Pro's battery boxes that have roll offs that change radically depending on the impedance of the recorder's input.
