• Encoders and ENTER, ESC buttons
The DS-EQ230 is equipped with 3 Relative Encoders, “NAV/PM1”, “PM2” and “PM3”. These
encoders allow you to navigate the user interface and edit sections of the processor. They allow
the user to navigate within the screen for the selection of sub-menus, pages and parameters and to
select the values to be assigned during the editing operations.
The “ENTER” and “ESC” buttons allow the user to confirm or NOT confirm the operations
performed by the encoders.
• UTILITY, LIN/RIN and LOUT/ROUT/LCOMP/RCOMP buttons
The UTILITY button allows the User to enter the Sub-menus and set the general characteristics of
the Equalizer. The LIN and RIN buttons allow the User to enter the Editing Menus of the Equalizer’s
Input Channels or to MUTE the Equalizer’s Outputs.
LOUT/ROUT and LCOMP/RCOMP buttons, allow the User to access UTILITY functions related to
the Equalizer (LOUT/ROUT) or to enter the Editing Menus of the Equalizer’s Compressors Section
(LCOMP/RCOMP).
The BYPASS functions allows to bypass the Equalizer setting (LOUT/ROUT) or the Compressor
setting (LCOMP/RCOMP).
As understood, the LIN/RlN as well as the LOUT/ROUT and LCOMP/RCOMP buttons have double
functions dependent on the push and hold time.
When the LIN/RIN buttons are pushed and held for more than one second, Input Channels LIN or
RIN are either muted or unmuted. The red LED will illuminate when the Channel is muted. When
the “MUTE” LED is OFF, then the related Input Channel is UN-MUTED.
A momentary push of the LIN/RIN buttons enters the Editing Mode for the Equalizer’s Channels
(see later for the Equalizer ’s Channel Editing details).
The blue “EDIT” LED will now be ON.
When the LOUT/ROUT buttons are pushed and held for more than one second, the Equalizer will
go into bypass and the red LED will illuminate indicating bypass. To remove from bypass push and
hold again for more than one second, the red LED will turn off indicating the Equalizer is now in
circuit.
When the LCOMP/RCOMP buttons are pushed and held for more than one second, the
Compressor will go into bypass and the red LED will illuminate indicating bypass. To remove from
bypass, push and hold again for more than one second. The red LED will turn off indicating the
Compressor is now in circuit.
A momentary push of the LOUT/ROUT buttons enters Utilities’ functions for the Equalizer ’s
Channels (see later for the Equalizer’s Utilities Functions details). The blue “UTILITY” LED will
now be ON.
A momentary push of the LCOMP/RCOMP buttons enters the Editing Menu for the Equalizer ’s
Compressor Section (see later for the Compressor ’s Editing details). The blue “EDIT” LED will
now be ON.

• DS-EQ230 Menu and Sub-Menu Structures
As stated above, the start-up default screen is the following factory preset:
DS-EQ230
Default Flat
From this point, sub-menus are accessed using the “UTILITY”, “LOUT/ROUT”, “LCOMP/RCOMP”,
“ENTER” and “ESC” buttons and all parameters and values are navigated by the “NAV/PM1”,
“PM2” and “PM3” encoders. Please refer to the following menu structures:
• Menu "UTILITY" [access by pushing the "UTILITY" button]
From the “Default Screen”, it is possible access the “UTILITY” menu pushing the “UTILITY” button
and the Sub-Menus pages can be selected just rotating clockwise and counter-clockwise the
“NAV/PM1” encoder.
Once selected the sub-menu page, using the “ENTER” button can be accessed the Sub-Menus
pages, again “scrollable” using the “NAV/PM1” encoder and accessible for the parameters’ editing
pushing again the “ENTER” button.
Through the “ESC” button, it is any time possible to go back to the action and page preceding the
“ENTER” button use.
Once inside the Sub-Menus pages, the several options can be scrolled and using the “PM2” or
“PM3” encoders and selected/confirmed pushing the “ENTER” button.
Note: In every Sub-Menu the option currently selected/running will have an asterisk “*” showing to
the right of the description on the LCD screen
.

Will become active and an asterisk will now appear to the right of the option description.
The following two options are available:
FADE-In = Off ... when the DS-EQ230 is turned on, all Outputs regardless of their status before
The Unit was switched off, will be MUTED or UNMUTED automatically. Meaning the DS-EQ230
will have no active Outputs or active Outputs, during the start-up process, depending from the
Outputs’ previous status.
FADE-In = On ... when the DS-EQ230 is turned on, all Outputs not previously muted before the
Unit was switched off will be active. Meaning the DS-EQ230 outputs will be controlled by a volume
ramp to avoid any sudden sound.
If the option “Fade-In=On” is selected, the screen will show the following:

- Ramps on Changes -
When connected to the DS-EQ230 by the PC remote control software, it is possible to request
sudden parameter changes where the difference between the old parameter and the new one
Can cause unwanted “click” noises (big differences in volume changes) or “bumps” (big
differences in Hp/lp filters cutting frequency values) as the DSP reconfigures.
The Fading-In and Fading-Out ramps eliminate any potential clicks and bumps.
This function can be de-activated when the unit needs to be used in “live” conditions and small
parameter adjustments are requested “on the fly” during live performance.
The following screen shows the Fading ramps function is Off, and therefore de-activated:

The DS-EQ230 allows the user to select either Bell or Shelving Parameters and assign them
independently using the 30 available filters.
In order to select the filter’s type, it is necessary to have the filter ’s GAIN=0.0dB, then using the
“PM2” encoder, rotate it “clockwise” in order to decide the Bell filter ’s Bandwidth, or
“counter-clockwise” to select the Shelving filter type (Low or High) and its order (1st or 2nd ).
So, in order to define the filter type for the filter number 1 (“x”=1), it is necessary from the above
Screen, to enter the filter's editing page pressing the ENTER button, and the screen has to appear
as follows:
OutputA Left EQ-1
-> 1.00KHz BW1.05 0.0dB
DPA-240A
1x2 WAY X-OVER
In this case, the filter’s GAIN=0.0dB, and being BW=1.05, the current filter selected is a Bell type.
Now, rotating the “PM2” encoder clockwise, the parameter BW will range from 0.05 up to 3 for
identifying a bandwidth value for a Bell filter.
If a Bell filter is selected, then the Gain can be modified from 0.0dB and the BW will range
between 0.05 and 3.
If the user wants to select a Shelving filter from the above setting, with the GAIN=0.0dB [if the
GAIN is not 0.0dB, it is necessary to set it at 0.0dB using the “PM3” encoder], rotate the “PM2”
Counter-clockwise. Once BW reaches the 0.05 value, at the next step of the “PM2”
counter-clockwise rotation, the selection of the Shelving filters will be entered.
Still rotating the “PM2” counter-clockwise, the Shelving filters and their order will be selectable in
the following sequence:
1. 1st Order Low Shelving = -6LoSh [on the screen]
2. 2nd Order Low Shelving = -12LoSh [on the screen]
3. 1st Order High Shelving = -6HiSh [on the screen]
4. 2nd Order High Shelving = -12HiSh [on the screen]
Once the desired Shelving filter is selected, the “PM3” can then be used to select the desired GAIN
and when the GAIN is set at a value different from 0.0dB, then the filter type cannot be changed
until this GAIN is returned to 0.0dB.
BELL Filter: As an example, if we want to set a bell filter within EQ-1, then the BW has to be set
At a desired value of say 1.00 using the “PM2” encoder, the GAIN at say +3dB using the “PM3”
encoder and the center Frequency at say 1.00KHz with the “NAV/PM1” encoder.
The EQ sub-menu screen will show the following:

Once in the Bell Filter ’s edit screen all the filter's parameters can be modified using the
“NAV/PM1”, “PM2” and “PM3” encoders for editing the Filter’s Center Frequency, Bandwidth BW
and Gain.
The Center Frequency of the Parametric Filter can be edited using the "NAV/PM1" encoder, the BW
the "PM2" encoder and the Gain the "PM3" encoder:
“Center Frequency”: the selectable frequencies range is from 20Hz to 20kHz in steps of 1/24 of
an Octave and can be adjusted by rotating the “NAV/PM1” encoder.
“Bandwidth BW”: the selectable BW range is from 0.05 Octave to 3 Octave in steps of 0.05
Octave and can be adjusted by rotating the “PM2” encoder.
“Gain”: the selectable Gain range is from -15dB to +15dB in steps of 0.5 dB and can be adjusted
by rotating the “PM3” encoder.
Low Shelving Filter: As an example if we want to set a low shelving filter within EQ-1 then the
“PM2” encoder has to be rotated counter-clockwise until the desired Low Shelving filter say
-6LoSh appears on the screen, the GAIN at say +3.0dB using the “PM3” encoder and the High Cut
Frequency at say 1.00KHz with the “NAV/PM1” encoder.
The EQ sub-menu screen will show the following:
DPA-240A
OutputA Left EQ-1
-> 1.00KHz -6LoSh + 3.0dB

Note: Once the desired Low Shelving filter is selected, the “PM3” can then be used to select the
desired GAIN and when the GAIN is set at a value different from 0.0dB, then the filter type cannot
be changed until this GAIN is returned to 0.0dB.
Once in the Low Shelving Filter’s edit screen all the filter’s parameters can be modified using the
“NAV/PM1”, “PM2” and “PM3” encoders for editing the Filter’s High Cut Frequency, Filter’s Order
and Gain.
The Hi Cut Frequency of the Low Shelving Filter can be edited using the “NAV/PM1” encoder, the
Filter’s Order can be adjusted by the “PM2” encoder and the Gain the “PM3” encoder:
“Hi Cut Frequency”: the selectable frequencies range is from 20Hz to 20kHz in steps of 1/24 of an
Octave and can be adjusted by rotating the "NAV/PM1" encoder.
“Low Shelving Order”: the selectable Low Shelving Filter’s range can be selected between the
1st (Lo-1st.) and the 2nd (Lo-2nd.) one.
“Gain”: the selectable range of the Gain is from -15dB to +15dB in steps of 0.5 dB and can be
adjusted by rotating the “PM3” encoder.
High Shelving Filter: As an example if we want to set a high shelving filter within EQ-1 then the
“PM2” encoder has to be rotated counter-clockwise until the desired High Shelving filter say
-6HiSh appears on the screen, the GAIN at say +3dB using the “PM3” encoder and the Low Cut
Frequency at say 1.00KHz with the “NAV/PM1” encoder.

• Factory Reset
In the event of the password being lost or any other reason, the user may require the unit to be
Reset to the original factory settings. A “Factory Reset” that will clear all settings of the
DS-EQ230 and return the device to the original factory setting, is available to the user.
Note: Continuing with this process will mean the DS-EQ230 will re-initialize to the original factory
settings and any previously stored information and changed parameters will be permanently lost.
Use the following procedure to perform the factory reset:
1. While the DS-EQ230 is switched OFF, simultaneously press the ENTER+ESC+UTILITY
buttons on the front panel.
2. Maintain pressure on all three buttons as you turn the power switch to On and the
following LCD screen appears on the DS-EQ230:
Please Wait . . . . .
Memory Reset
3. Release the buttons and wait for the DS-EQ230 to re-initialize.
Once completed, the DS-EQ230 will resume regular operation as though it was a new unit from
the factory and no previously programmed parameters will be available for use.
• GND and USB/RS485 LIFT Switches
The DS-EQ230 on its back panel is providing a couple of switches allowing to connect or left
Unconnected the power Supply Main GND and the USB/RS485 connectors GND to the chassis.
MAIN “LIFT/GND” Switch - At some times, it is necessary to NOT connect the Main Ground to the
Chassis in order to avoid GND loops.
This is possible using the “MAIN” GND/LIFT switch.
When the switch is positioned on GND, the Main Power Supply GND is connected to the Chassis.
USB/RS485 “LIFT/GND” Switch - When using a USB or RS485 remote control connection, it can
be that the GND of the USB or RS485 cable it is not connected to the remote controller GND.
In this case it is necessary to provide it from the processor’s side, and this can be done selecting
the GND position with the USB/RS485 switch.
On the other hand, if the GND of the USB/RS485 cable is already connected to the remote
controller GND, to connect the same ground also to the GND of the processor could create GND
loops or generate GND noises.
In this case, the switch on the position “Lift” will leave the cable GND not connected to the chassis
of the DS-EQ230.

• Equalizer’s Channels LIN/RIN and Compressor/Limiter ’s Channels
LCOMP/RCOMP Last Edited Parameter Return Function
Once you have escaped out of parameter editing within the individual Equalizer ’s Channel or
Compressor ’s Channel the DS-EQ230 will remember this last editing action on that Channel.
When you return for your next editing action pressing the EDIT button on that channel will
immediately return you to the screen related to this last editing action.
This function makes fine tuning or modifying easier when it is necessary to make a number of
adjustments to the same parameter in a short time sequence.
• Equalizer’s Channels and Compressor/Limiter’s Channels LINK Function
The DS-EQ230 is able to perform a unique LINK MODE between Equalizer ’s Channels as well as a
link between Compressor’s Channels to enable quick and immediate editing (you cannot link
Equalizer’s to Compressor ’s channels).
To link channels when editing, you will need to select a “Master” channel that will be the one to be
edited and have its parameters displayed on the LCD screen. You can then select and link the other
channel (Slave) that you wish to apply the same changes to.
To enter a link mode session, select the Master channel Edit mode, then link the Slave by pressing
their related Edit buttons.
Once Linked, the channels will be selected ready for adjustment when their “Blue” LED is lit in the
Editing mode.
Now the Slave channel will modify its parameters accordingly as you edit the Master channel.
All other existing parameters will stay the same within the Slave Channel unless edited by this link
with the Master channel.
Note: The LINK function is NOT a COPY function.
If we want to edit the Limiter of the Equalizer’s Channel A (named Left), we can enter the editing
mode of Compressor’s Channel A by pressing the related LCOMP Edit button and turning on the
Blue LED below the LCOMP LED meters. This assigns the “role” of Master and displays this
Channel’s parameters on the LCD:
DPA-240A

Then press the Edit button of Compressor ’s Channel B, turning ON its related “Blue” LED’s. Now
All parameters edited on Compressor’s Channel A, will also be applied to channel B.
If we want to remove the linked channel from the Link, press the related Edit button.
Exiting the editing of the Master channel during a Link session will automatically terminate that
session. The Link will also be automatically terminated if, during the editing of Compressor ’s
Channels you jump across to begin editing an Equalizer ’s Channel or vice versa.
