EQ Band Controls
The individual EQ bands on each EQ III config-
uration have some combination of the follow-
ing controls, as noted below.
EQ Type Selector
On the 1 Band EQ, the EQ Type selector lets you
choose any one of six available filter types:
High-Pass, Notch, High-Shelf, Low-Shelf, Peak,
and Low-Pass.
On the 7 Band EQ and the 2–4 Band EQ, the
HPF, LPF, LF, and HF sections have EQ Type se-
lectors to toggle between the two available filter
types in each section.
Band Enable Button
(7 Band EQ and 2–4 Band EQ Only)
The Band Enable button on each EQ band tog-
gles the corresponding band in and out of cir-
cuit. When a Band Enable button is highlighted,
the band is in circuit. When a Band Enable but-
ton is dark gray, the band is bypassed and avail-
able for activation. On the 2–4 Band EQ, when a
Band Enable button is light gray, the band is by-
passed and unavailable.
Band Gain Control
Each Peak and Shelf EQ band has a Gain control
for boosting or cutting the corresponding fre-
quencies. Gain controls are not used on High-
Pass, Low-Pass, or Notch filters.
Frequency Control
Each EQ band has a Frequency control that sets
the center frequency (Peak, Shelf and Notch
EQs) or the cutoff frequency (High-Pass and
Low-Pass filters) for that band.
Q Control
Peak and Notch
On Peak and Notch bands, the
Q control changes the width of the EQ band.
Higher Q values represent narrower band-
widths. Lower Q values represent wider band-
widths.
Shelf
On Shelf bands, the Q control changes the
Q of the shelving filter. Higher Q values repre-
sent steeper shelving curves. Lower Q values
represent broader shelving curves.
Band Pass
On High-Pass and Low-Pass bands,
the Q control lets you select from any of the fol-
lowing Slope values: 6 dB, 12 dB, 18 dB, or
24 dB per octave.
