Frequencies above and below this, within the bounds of the Q setting will be affected by the HI MID level control.
That is, Q effectively sets the 'width' (bandwidth) of the filter's bell shape and FREQ sets the frequency at the
centre of the bell shape.

Q is 'magnification' at resonance, and is inversely proportional to bandwidth. For an equaliser it is useful to think
of it simply as a bandwidth control (the width of the 'bell' in the case of a bell-shaped filter). That is, the higher
the Q, the lower the bandwidth - or the more 'focussed' the filter. Bandwidth (in octaves) is shown on the Touch
Screen with the Function Focus feature.
LO MID Le el
LO MID FRE
Frequencies above and below this, within the bounds of the Q setting will be affected by the LO MID level control.
That is, Q effectively sets the 'width' (bandwidth) of the filter's bell shape and FREQ sets the frequency at the
centre of the bell shape.
