THE EQ MODuLE
Controls and Display
To edit a single band
with the Eq/rta indicator off, turning or pushing the
GrAPHIC EDIT knob will bring you to the Eq Band
Select Mode. See table1 for tips on identifying the
control modes. to select a band, simply turn the
GrAPHIC EDIT knob. the selected band is the one
that has a slow-blinking lED (the cursor). to change
from channel 1 to channel 2, turn the GrAPHIC
EDIT knob clockwise until the cursor "jumps" to the
right pane. once a band is selected, you can edit
its boost/cut level by pushing the GrAPHIC EDIT
knob once. the cursor will blink faster to indicate
that you are now in the Eq Band Edit Mode. while
in this mode, turning the GrAPHIC EDIT knob will
boost or cut the gain level of the band. after you
are done editing the band level, push the GrAPHIC
EDIT knob once again to return to the Eq Band
Select Mode.
To edit a multiband group
while in the Eq Band Select Mode, turning the
fuNCTION EDIT knob lets you select multiple
bands as a group. for example, if the lED is
originally blinking only at the 10k band of channel
1, turning the fuNCTION EDIT knob clockwise
by two notches will make these three lEDs blink:
10k, 12.5k, and 16k. if instead of two notches, you
turn the knob clockwise by five notches, you will
notice that the blinking lEDs are no longer limited
to channel 1 (at 10k, 12.5k, 16k and 20k hz), but
also include two bands of channel 2 (at 25 and 31
hz). this means you can group across the channels
even when Channel Link is off. in practice, you
may often want to raise or lower the boost/cut level
of the entire spectrum of both channels. this cross-
channel grouping makes the task quick and easy
without having to link the channels.
once a group is selected, push the GrAPHIC EDIT
knob to enter the Eq Band Edit Mode; notice the
lEDs are blinking faster. now turn the GrAPHIC
EDIT knob to edit simultaneously the boost/cut level
of all selected bands. push the GrAPHIC EDIT
knob again to return to the Eq Band Select Mode.

functions
with the EQ/rTA indicator off, pushing the fuNCTION
EDIT knob once will bring you to the Eq function
Select Mode. See table 1 for tips on identifying the
control modes. while in the Eq function Select
Mode, the upper line of the alphanumeric Display
provides important information on the current Eq
settings. This information includes the following five
values.
program number: P1 through P30 are factory-
set programs, and u1 through u30 are user-
defined programs.
Low-pass filter: The letters LPf appears
when the low-pass filter is active. This value is
channel dependent.
High-pass filter: The letters HPf appears
when the high-pass filter is active. This value
is channel dependent.
gain: G+ indicates that a gain increase is been
applied to the output; G– is for gain decrease;
and G= is for zero gain. this value is channel
dependent.
channel link:
appears when the channel link
is on. otherwise,
is displayed.
the lower line of the alphanumeric Display shows
a function name and its current value. when you
are in the Eq function Select Mode, the entire
lower line is flashing. This is to remind you that, if
you turn the fuNCTION EDIT knob now, you will
be "scrolling" through the function menu. turn the
fuNCTION EDIT knob to find the function that you
want to edit. press the fuNCTION EDIT once to
enter the Eq function Edit Mode. notice that the
function name is no longer flashing and that only
the variable value is. turning the fuNCTION EDIT
knob now will change the value for that function.
When you have finished adjusting the value, press
the fuNCTION EDIT knob again to return to the Eq
function Select Mode.
the following sections describe all functions you
can adjust in the Eq function Edit Mode.
