Yamaha LS9-16 User Manual

LS9-16/32  Owner’s Manual

The window contains the following items.

1

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

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

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

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

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

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

This switches the EQ on/off.

H

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

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

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

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

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.

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.
