Making this more specific to the B7K Ultra because I am not quite sure the true proper forum to put this in, but I would also like to know if the answer generally applies anything with an equalizer. I am playing around with the B7K to get some certain tones and need some help. The frequencies are listed as: (Sorry, I have no idea why the forum adds so much space between the table) Band Frequency Bass 100Hz Lo Mids* 250/500/1000Hz Hi Mids* 750/1500/3000Hz Treble 5kHz * means selectable As I never really cared before, I just turned knobs until it sounded good, but now I am actually interested in exactly which direction the frequencies are being boosted or cut. So given this scenario of Bass @ 100Hz, Lo Mids @ 250Hz and Hi Mids @ 750Hz; what frequencies are affected by the Lo Mid knob? Is it 101-250Hz or is it 251-750Hz? Basically are these cut off points, starting points? My brain is telling me that these would be cutoff points, but would love a confirmation as it is actually really hard to find anything that specifically states what the number actually refers to on an EQ; just generalities.
