All EQ's function by altering
the gain above or below normal over various frequency ranges. Some mixers
offer "semi-parametric" EQ. This usually comes in the form of one or more
cut/boost controls, each with a frequency control to position the cut/boost
exactly where you want it along the frequency spectrum. One application
of such a feature is in the fight against feedback. Here you would turn
the cut/boost control counter-clockwise to produce a "dip" in the frequency
response, then rotate the frequency control until the dip reaches the guilty
frequency and the feedback is reduced.
The SWEEP control determines
what range of frequencies is affected by the MID cut/boost. It moves or
"sweeps" the MID control's peak or notch in response all the way up to
several thousand Hz or down to below one hundred Hz. As a result it can
have quite a noticeable effect on the sound especially since the MID cut
or boost will be interacting with whatever cuts or boosts you may have
set with the LOW or HIGH EQ controls. If you have set a LOW boost, a MID
boost swept all the way down to the lowest frequency setting will alter
the sound of lows AND increase their volume. As music plays through a channel
on the mixer and speakers, adjust that channel's MID, first for a boost
then for a cut and SWEEP them back and forth. (If there is no MID cut or
boost setting, i.e. if it is set at the center position, the SWEEP will
have no effect at all). Now repeat the process with that channel's LOW
and HIGH EQ controls at various settings (but with the volume at a safe
level for the speakers).
Most EQ sections include
an optional High Pass Filter, which inserts a Low Frequency Cut at a pre-selected
frequency usually at or near 80Hz. By invoking the HPF you automatically
attenuate these lower frequencies. This feature can be very useful in cleaning
up the mix by removing ambient low frequencies from open vocal mics.
