Graphic Equalizer [GEQ]
5.15
The
Graphic Equalizer
is a multi-band equalizer capable of running in 5,7, 8, or 10 band configurations.
Each instance of the Graphic EQ block stores two fully independent sets of parameters called
X
and
Y
. Selecting
between these allows you to change all block settings—instantly—at the touch of a switch or button (excluding
any
Modifier
for more information.
The GEQ block supports X/Y Switching on the XL/XL+ only. See p.
Each Axe-Fx II preset can use four fully independent
Graphic Equalizer
blocks.
The
TYPE
determines the number of bands.

Each band can boost or cut up to 12 dB. The outermost bands are shelving filters.
The above modes can be run as Constant Q or Variable Q. In a variable Q equalizer, the bandwidth varies as a
function of boost/cut levels, such that lower boosts/cut levels result in a lower Q.
MASTER Q
adjusts the Q of all bands. A value of 1.0 sets the Q to the default value (typically one octave). Lower
values increase the bandwidth and overlap of each band, higher values decrease the bandwidth.
Two
Passive EQ
types are also offered: 4-band (Low, Low Mid, High Mid, and High) and 3-band (Low, Mid, High),
plus a
3-band Console
type. These models capture the characteristic sound of vintage analog gear.
For any type, press ENTER while on PAGE 1 of the block’s edit menu to reset all bands to flat.
The
AMP
block (p.
) has a built-in graphic equalizer at its output, making it unnecessary to follow it with a
separate GEQ. There is also a global, 10-band graphic equalizer on each output (p.
), which can be used to
modify the sound of
all
presets at once.
The
Graphic Equalizer
is stereo-in/stereo-out. Its
LEVEL
,
BALANCE,
and
BYPASS MODE
parameters are covered in
additional detail on p.
