Q or BW defines the quality or bandwidth of a parametric EQ.
A high Q-value results in a narrowband filter, while a small Q-
value results in a broadband filter. The Q-value also sets the
quality and thus the response of Hi, Lo and All pass filters
with slopes of 12dB/ oct.

SLOPE sets the steepness or filter-order of low or high
shelving equalizers and low or high pass filters. Setting
different slopes within the transmission range is possible.
That, in conjunction with the Q-parameter, offers the
possibility for a hi-pass filter to be programmed for B6-
alignment, which describes a drastic rise in the cut-off
frequency range.
BYPASS switches the corresponding filter ON (not engaged)
or OFF (engaged), which allows for quick A / B-evaluation of
the actual effect that a filter has on the sound.
