It's all about the Software

Hello,

Regarding the Audio Eq.:

Not important, but if someone could explain the purpose, and usage, of:

Low Shelf
High Shelf
and the Freq., Gain, and Slope options for, would be appreciative.

and the:

25 Hz HPF option box

I'm assuming the Enable box, if not checked, takes the Equalizer totally out of the audio chain. True ?

Thanks,
Bob
