Using EQ
LS9-16/32 Owner’s Manual
The window contains the following items.
1 TYPE I, II buttons
These buttons select the EQ type. If the TYPE I button
is on, the EQ will use the same algorithm as previous
Yamaha digital mixers; if the TYPE II button is on, a
newly-developed algorithm will be used. Using TYPE
II will reduce interference between bands.
B FLAT button
This button resets the GAIN parameter of all bands to
the initial value (0.0 dB). When you move the cursor
to this button and press the [ENTER] key, a dialog box
will ask you to confirm the operation.
C EQ graph
This graph shows the approximate response of the EQ
parameters. A pointer is shown at the peak of each
band. Operating the Q, FREQ, or GAIN knobs of each
band will change the response curve accordingly. If
EQ or high-pass filter is on, the response curve will be
highlighted.
D Level meter
This meter indicates the peak level before the EQ and
after the EQ. If the signal has overloaded before or
after the EQ, the OVER segment will light. If the cor-
responding channel is stereo (a ST IN channel, a MIX
channel / MATRIX channel that is set to stereo, or the
STEREO channel), level meters for two channels will
be displayed.
E ATT knob
This knob specifies the amount of attenuation/gain
before entering the EQ, in a range of -96 dB–+24 dB.
Use this to compensate for level changes caused by the
EQ.
F HPF FREQ knob, HPF ON/OFF button
(input channels only)
This knob and button let you adjust the cutoff fre-
quency of the high-pass filter placed immediately after
the attenuation and before the EQ, and switch it on/off.
The cutoff frequency can be adjusted in a range of 20–
600 Hz.
G EQ ON/OFF button
This switches the EQ on/off.
H LOW shelving button
If this button is on, the LOW band EQ will switch to a
shelving type. In this case, the LOW band Q knob will
not be shown.
I Q/FREQ/GAIN knobs
For each of the LOW, LOW MID, HIGH MID, and
HIGH bands, these knobs adjust the Q (steepness),
FREQ (center frequency), and GAIN (amount of
boost/cut).
J HIGH shelving button
If this button is on, the HIGH band EQ will switch to a
shelving type. In this case, the HIGH band Q knob will
not be shown.
K Low pass filter button
If this button is on, the HIGH band EQ will operate as
a low-pass filter. In this case, the HIGH band Q knob
will not be shown, and the GAIN knob will operate as
a switch that turns the low-pass filter on/off.
L High-pass filter button (output channels
only)
If this button is on, the LOW band EQ will operate as a
high-pass filter. In this case, the LOW band Q knob
will not be shown, and the GAIN knob will operate as
a switch that turns the high-pass filter on/off.

To turn the EQ on/off, move the cursor to
the EQ ON/OFF button and press the
[ENTER] key.
If you want to make settings in the ATT/HPF/EQ
popup window, move the cursor to the desired button/
knob and use the [ENTER] key, the dial, or the [DEC]/
[INC] keys.

• You can also adjust the Q, center frequency, and boost/cut
amount using the EQ [Q], EQ [FREQUENCY], and EQ [GAIN]
encoders of the SELECTED CHANNEL section. In this case,
use the EQ [HIGH], EQ [HIGH MID], EQ [LOW MID], and EQ
[LOW] keys to select the band that you want to adjust. You
can also switch EQ bands for editing by moving the cursor
onto a parameter of the desired band.
