MID Here you determine how much the mid band should be boosted or cut (MIDmode).
You have a control range from -12 to +12 dB. By pressing the controller you change to
the MID. Now you can set the desired frequency (see also under FREQ).
HIGH Like the low-band, the hi band also has a shelf-characteristic with a cutoff frequency at
12 kHz. Again, you have a control range from -12 to +12 dB and a low pass filter at 12
kHz.
