Tool buttons
Copy the currently-displayed 31BandGEQ settings to the GEQ of another rack, or 
initialize the settings. For details on how to use the tool buttons, refer to “Using the tool 
buttons” in the separate Owner's Manual.
NOTE• Only 31BandGEQ settings that use fifteen bands or less can be copied to a Flex15GEQ.
• GEQ settings can be stored and recalled at any time using the dedicated library.
Using the Flex15GEQYou will use the Centralogic section's faders 1-8 and [ON] keys to control the Flex15GEQ.
A rack in which a Flex15GEQ is mounted will show information for two GEQ units (A and B) 
in the VIRTUAL RACK window.
NOTE
If you mount a Flex15GEQ, two monaural 31BandGEQ units will be placed in a single rack. 
However, only up to fifteen bands can be adjusted for each unit.NOTE• The [ON] key will light if you raise or lower a fader even the slightest amount. This indicates that 
the corresponding band is being modified.
• To quickly return a boosted or cut band to the flat position, press the corresponding [ON] key in 
the Centralogic section to make it go dark.• With CL version 2.0 or later, pressing the [ON] key again for this band will restore the adjusted 
gain value. In this way, comparison is easy and quick. However, please note that if the [ON] key 
for this band is off and if you press the [ON] key for the fader of a different frequency band, the 
adjusted gain value will be canceled and will return to ± 0dB.
• If you switch the display to a different screen, the fader assignments in the Centralogic section 
will forcibly be defeated. However if you once again display the same rack, the group of bands 
you had previously been controlling will automatically be assigned to the faders.
• When you close the GEQ window, the buttons in the FADER ASSIGN field automatically turn off.
GEQ EDIT window (Flex 15GEQ)
This window is the same as that for the 31BandGEQ, except that the AVAILABLE BANDS 
parameter box indicates the real-time number of additional bands (maximum 15) that 
can be controlled in the current GEQ.
For a rack in which a Flex15GEQ is mounted, the rack switch tabs will be split as xA and 
xB (x is the rack number). STEP
1.Press the rack container in which you mounted Flex15GEQ.
2.Press the GEQ ON/OFF button to turn the Flex15GEQ on.
3.Press one of the buttons in the FADER ASSIGN field to select the group of bands you 
will control.
4.Use the faders in the Centralogic section to adjust the selected band.
5.When you've finished making settings, turn off the buttons in the FADER ASSIGN 
field.

Parametric EQ operationsIn addition to the standard 4-band EQ, CL series consoles also feature an 8-band parametric 
EQ (PEQ) that can be rack mounted. You can mount this PEQ in GEQ racks 1-16 and patch 
it to the insert-out/in of an input channel (GEQ 1-8 rack only), a MIX/MATRIX channel, or a 
STEREO/MONO channel. You can also mount it in EFFECT racks 1-8 (FX 1-8) and patch it 
to the insert-out/in of an input channel, MIX/MATRIX channel or STEREO/MONO channel. 
The gain of each band can be adjusted using the Centralogic section's faders and [ON] keys. 
The following type of PEQ is provided.
8BandPEQ
This is a monaural 8-band PEQ. There are also an independent HPF, LPF, and 3 notch filters.
Two 8BandPEQ units (shown as “A” and “B” respectively) can be mounted in a rack, and 
therefore you can use two channels of input and output for each rack.Inserting a PEQ in a channelThis section explains how to insert a PEQ into the selected channel for use.
NOTE
• You can view the input and output levels of the PEQ in the rack in the GEQ or EFFECT field.
• For details on PEQ operations, refer section “PEQ EDIT window” (page 132).

About AUTOMIXERAutomixer is included as a standard feature on the CL series. Automixer searches for enabled 
mics and automatically optimizes gain distribution, for uses such as speeches without scripts. 
This allows uniform system gain to be maintained among multiple mics, freeing the engineer 
from making constant fader adjustments.Automixer operating principleWith the Dugan speech system used in Automixer, you can automatically adjust the automix 
gain for up to 16 mics used for speeches.
The Dugan speech system functions differently from a limiter or auto level controller. When 
multiple people are speaking, the engineer can adjust the each level using the faders as 
normal. Even if nobody is speaking, the system searches for mic audio and automatically 
distributes gain. Therefore, faders can be left in their raised positions.
Inserting Automixer in channels post-faderThis section explains how to mount Automixer in a virtual rack, and insert Automixer input and 
output into channels (excluding ST IN channels) post-fader (POST ON). For details on 
Automixer operations, refer to the following section “Using Automixer.”Using AutomixerChannel display
The auto mix gain meter for each channel and man (yellow), auto (green), and mute (red) 
settings are shown for channels 1-8 and channels 9-16.
If you select the channel 1-8 or 9-16 region, the display channel for the channel control field 
will switch to 1-8 or 9-16.
(For 8ch Automixer, only channels 1-8 are shown.)
When 1 person speaks on multiple mics When 2 people speak on multiple mics
When 1 person is speaking, the gain on the mic 
being used is immediately increased and the gain 
on all other mics is reduced. The same operation 
occurs even if another person is speaking.If 2 people are speaking at the same time, gain is 
automatically distributed so that the total gain is 
consistent across both mics, and the gain on the 
remaining mic is reduced.Gain (dB) in

STEP
1.Refer to steps 1-8 in “Virtual rack operations” (page 125) to mount Automixer in 
rack 1 and set its input source and output destination.
2.Refer to “Inserting an external device into a channel” (page 20) to insert Automixer 
in post-fader (POST ON field).

Channel control fieldEach channel is always in man, auto, or mute mode. The indicator for the enabled channel 
mode will light. To select a mode, either press the button for that mode or press the PRESET 
button in the master field.1
Level indicator
Lights green when the audio is at an optimum level for Automix.
NOTE• If the level indicator flashes, increase the input gain.
• If the level indicator lights up red, reduce the input gain.
2
Meter indicator
There are three display modes. Pressing the meters button in the master field will switch 
modes.
NOTEMeters should normally be set in gain mode.
3
weight
Adjusts the correlative sensitivity between input channels. When there is no input, adjust 
the weight setting so that all auto mix gain meters are at about the same level. For 
example, if you can hear noise near one mic (such as noise from a computer ventilation 
fan or an air conditioner), you can suppress the noise by reducing the weight setting for 
that channel.
To change the channel weight settings, use the [TOUCH AND TURN] knob to adjust the 
weight slider.
Automixer calculates the ratio of input level for specific channels for all input mixes in the 
group. The following example explains the weight control mechanism.When increasing the weight setting in one channel• The value displayed in the auto mix gain meter for that channel increases, while the 
values for other channels are reduced.
• Channels with high weight setting values receive a higher automix gain than other 
channels.When reducing the weight setting in one channel• The value displayed in the auto mix gain meter for that channel decreases, while the 
values for other channels are increased.
• When speaking into multiple mics at the same time, it is difficult to distinguish between 
different mics.
4
group
Each channel can be assigned to three groups (a/b/c).
This group function is convenient for the following uses.
• Using multiple rooms: Assign the mics in each room to their own groups, and use a 
different Automixer for each.
• Stereo pan: Assign mics panned to left, right and center to groups a, b, and c, to 
maintain a stable stereo field.
5
override
If you turn on the OVERRIDE button in the master field, the channel will switch to man 
mode or mute mode according to the settings for that channel's override button.
• When the channel's override button is on, the mode for that channel will switch to man 
when the master OVERRIDE button is turned on.
• When the channel's override is off, the mode for that channel will switch to mute when 
the master OVERRIDE button is turned on.
• When the master OVERRIDE button is turned off, the channel will return to its previous 
mode.
The override function is convenient when the moderator of a panel discussion wants to 
control the system.
Follow the instructions below to change the settings.
1.Turn on the override button on the moderator's channel.
2.Turn off the override button on all other channels.
3.Turn on the OVERRIDE button in the master field as needed.

Editing the internal effectsThe internal effects of the CL series console can be mounted in EFFECT racks 1-8, and 
patched to an output channel's output or input channel's input, or inserted into a channel. For 
each effect mounted in a rack, you can choose one of 54 types of effect.
With the default settings, the signals from MIX channels 17-24 are input to racks 1-8, and from 
the racks are then output to ST IN 1-8 (L/R).
NOTE
Some effect types can be mounted only in racks 1, 3, 5 or 7.
To use an internal effect via send and return, assign the output of a MIX channel to the input 
of the effect, and assign the output of the effect to an input channel. In this case, the 
corresponding output channel is used as a master channel for the effect send, and the input 
channel is used as an effect return channel.
Alternatively, you can assign the input and output of the internal effect to the insert-out/in of a 
desired channel (except for a ST IN channel), so that the effect is inserted into that channel.
The internal effects fall into two categories; “STEREO type” (2-in/2-out) effects that process 
the L/R channel input signals independently, and “MIX type” (1-in/2-out) effects that mix the 
two channels before processing them.
If signals are assigned to both the L and R inputs of an effect, the way in which the L/R 
channels are processed will depend on whether a Stereo effect type or a Mix effect type is 
selected, as follows.

STEREO type effects
MIX type effectsIf a signal is assigned to only one input of a two-input effect, it will be processed as mono-in/
stereo-out regardless of whether a Stereo effect type or Mix effect type is selected. However, 
please note that this will not apply to COMP276, COMP276S, COMP260, COMP260S, 
EQUALIZER601, and OPENDECK.Using an internal effect via send and returnThis section explains how to use a MIX bus as an effect send bus and a ST IN channel as an 
effect return channel, so that the effect can be used in a send and return configuration.
NOTE
• If you want to use a MIX bus as an effect send bus, select “VARI” as the bus type. This will allow 
you to adjust the send level separately for each input channel.
• If you want to use the input to an effect in stereo, it can be convenient to assign the send-
destination MIX bus to stereo. (For details on bus assignments, refer to page 51.)
NOTE• If you're using a stereo source, assign the L/R signals of the stereo MIX channels to the L/R inputs 
of the rack.
• If you're using the output of the effect in stereo, assign the R input of the ST IN channel selected 
in step 3 to the R output of the rack.
• You can select more than one output destination for the effect.
• For more information on setting the effect parameters, refer to “Editing the internal effect 
parameters” (page 139).
Adjusting the effect send level of a input channelIn the TO MIX/TO MATRIX field in the OVERVIEW screen, press and select the TO MIX SEND 
LEVEL knob for the MIX bus set as the input source for the rack, and use the multifunction 
knob to adjust the send level of the signal sent from each channel to that MIX bus.
NOTE
• If a MATRIX bus is shown in the TO MIX/TO MATRIX field, use the [MIX 1-16] key or the [MIX 17-
24/MATRIX] key in the SELECTED CHANNEL section to select the MIX bus at the input source 
for the rack.
• When adjusting the effect send level, make sure that the send level from the ST IN channel you 
selected as the output destination for the rack to the corresponding MIX bus is set to 0. If you 
raise this send level, the output of the effect will be returned to the input of the same effect, 
possibly causing oscillation.
• If you press the knob once again, the MIX SEND window (8ch) for the send-destination MIX bus 
will appear. This window contains on/off switches for the signals sent from each channel to the 
corresponding bus, and lets you select the send point (PRE or POST) (page 38 ).
STEP
1.Follow steps 1-3 described in “Virtual rack operations” (page 125), to mount an 
effect in a rack.
2.Press the INPUT PATCH L button in the VIRTUAL RACK window, and select a MIX 
channel as the input source for the rack (page 125).
3.Press the OUTPUT PATCH L button in the VIRTUAL RACK window, and select the L 
input of a ST IN channel as the output destination for the rack (page 125).
4.Adjust the send level from each channel in the TO MIX/TO MATRIX field in the 
OVERVIEW screen.
5.Adjust the master level of the effect send of the MIX channel you selected as the 
input source for the rack.
6.Adjust the effect return level of the ST IN channel you selected as the output 
destination for the rack.INPUT L EFFECT L L RETURNINPUT R EFFECT R R RETURNINPUT L L RETURNINPUT REFFECT

Adjusting the master level of the effect sendTo adjust the MIX channel you specified as the input source for the rack, first call it up to the 
Centralogic section and then make adjustments by operating the fader.
Set the level as high as possible without allowing the post-effect signal to reach the overload 
point.
NOTE
The input and output levels of the effect are shown by the input/output meters in the upper right 
of the EFFECT EDIT window.
Adjusting the effect return levelTo adjust the effect return level, first call up the ST IN channel you specified as the output 
destination for the rack to the Centralogic section and then make adjustments by operating 
the fader.Inserting an internal effect into a channelThis section explains how to insert an effect into a channel by assigning the input/output of 
the internal effect to the input/output of the desired channel (except for a ST IN channel). For 
details on editing the effect parameters, refer to “Editing the internal effect parameters.”NOTE
• If you are inserting an effect into a channel that handles a stereo source, assign the R channel 
insert-out/insert-in to the R input and output of the effect in the same way as step 3.
• For more information about how to operate the INSERT/DIRECT OUT window, refer to “Inserting 
an external device into a channel” (page 20).
• The levels before and after the effect are shown by the input and output meters in the upper right 
of the EFFECT EDIT window.
• Adjust the effect send master level and the effect parameters so that the signal does not reach 
the overload point at the input or output stage of the effect.
