Getting Started

• 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:

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:

DS-EQ230

Default Flat

• 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

Options that are not selected/running will be displayed with NO Asterisk.

Pushing the ENTER button on an unselected option will mean an asterisk will then appear and this

option will now take over as the currently selected/running option.

System Utilities Sub-menu - this sub-menu allows to access several operations related to the

DS-EQ230 Start Up and General Configuration:

UTILITY MENU

- System Utilities -

From the “System Utilities Sub-menu”, pushing “ENTER” and then using the “NAV/PM1” encoder

for scrolling will give access to the following pages:

- Power-On Procedure: this gives you the ability to select the option that will apply when

the DS-EQ230 powers up after being switched on:

By pressing ENTER and rotating the “PM2” or “PM3” encoder, it is possible to choose between

two options: “Fade In On” or “Fade In Off".

The currently running option will be displayed with an asterisk to the right of the option description.

To change the option simply ENTER on the option not displaying the asterisk and that option

Will become active and an asterisk will now appear to the right of the option description.

SYSTEM UTILITY

- Power-On Procedure -

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:

Delay Time/Distance: this page allows you to select the measurement unit to be used for the

Delays: Time (in milliseconds “ms”) or Distance (in meters “m”):

By pressing ENTER and rotating the “PM2” or “PM3” encoder, it is possible to select the

measurement unit to be used for the delay, which will be confirmed by pushing the ENTER button.

The following screen shows the selected delay measurement is Time (milliseconds):

Ramps on changes: this page allows you to activate or de-activate Fading-in and Fading-out

ramps on the input/output volumes when any parameter 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:
