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.

Frequencies above and below this, within the bounds of the Q setting will be affected by the LF 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.

The LF band is normally bell-shaped. When Q is turn to maximum, shelf mode is enabled and the shelving LED
will light. Q is 'magnification' at resonance, and is inversely proportional to bandwidth. For an equaliser it is useful
