detent if you are unfamiliar with the bandwidth
feature. This setting will give you a semi-para-
metric type of EQ.

The 8•Bus console’s set of three HI-MID con-

trols (boost/cut, frequency center and
bandwidth) is VERY powerful in its effects.
Rarely if ever will you need more than a few dB
of boost and cut or, as noted above, will you want
to stray from the NORMAL (2 octave) bandwidth
until you gain some experience recording and
mixing.

The LO MID EQ section is called a semi-para-

metric equalizer, because the bandwidth is not
adjustable (Figure 2). The frequency range is 45Hz
to 3kHz and the bandwidth is fixed at 2 octaves.

boost or cut of this section,
through a range of

±15dB, is

set with the top knob. The cen-
ter frequency is dialed in with
the middle knob, and can be
set anywhere between 500Hz
and 18kHz. Finally, the band-
width of the bell-shaped
response curve around the
selected frequency (also some-
what inaccurately referred to
as a ratio known as Q) can be
selected with the lower knob.
The range is from as wide as 3
octaves to as narrow as 1/12
octave. Leave it at the center
