Mackie Onyx 400F

Archived from groups: rec.audio.pro (More info?)

To me the Onyx 400F is a an attractive entry-level package for
capturing 1-4 channels of sound, but the quoted -3dB 10-24K (-48K,
-96K) frequency response is discouraging. Is it a fair assumption the
Mackie engineers put a zero at 10Hz? Do I have to recall some math to
figure out the loss at the traditional lower bound of 20 Hz?

Thanks,

Brian

If the low end were set by a single pole filter, then the
response would be -3 dB at 10 Hz and -1 dB at 20 Hz.
