DLM26 Digital Speaker Processor
User Manual
Described below are the functions of the front panel control buttons and encoders for the DLM26.
• Getting Started
As soon as the DLM26 is turned ON the device model name will appear in the LCD screen:
and a status bar will show the pro ress of the DLM26 initialization process:
The DLM26 has three factory pre-set workin modes: “2x2 Ways Xover + Sub”, “2x3 Ways Xover”
and “6 Ways Xover”.
After the initialization, the DLM26 will show on the LCD the first of the embedded preset workin
modes, or the last one selected prior to the unit bein turned off.
First time activation will default to the first of the preset workin modes.

• Encoders and ENTER, ESC buttons
The DLM26 is equipped with 3 Relative Encoders, “NAV/Param.1”, “Param.2” and “Param.3”,
These encoders allow you to navi ate the user interface and edit sections of the processor. They
allow the user to navi ate within the screen for the selection of sub-menus, pa es and parameters
and to select the values to be assi ned durin the editin operations.
The “ENTER” and “ESC” buttons allow the user to confirm or NOT confirm the operations
performed by the encoders.
• UTILITY, A/B and 1/2/ /4/5/6 buttons
The UTILITY button allows the User to enter the Sub-menus and set the eneral characteristics of
the Processor. The A and B buttons allow the User to enter the Editin Menus of the Processor's
Input Channels and buttons 1, 2, 3, 4, 5 and 6, allow the User to enter the Editin Menus of the
Processor's Output Channels.
The A and B buttons as well as the 1, 2, 3, 4, 5 and 6 buttons have double functions dependent
on the push and hold time.
When the A and B buttons are pushed and held for more than one second Input Channels A or B
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 A and B buttons enters the Editin Mode for the Input Channels (see
later for the Input Channel Editin details).
The blue “EDIT” LED will now be ON.
When the 1, 2, 3, 4 , 5 and 6 buttons are pushed and held for more than one second the Output
Channels 1, 2, 3, 4 , 5 and 6 are either muted or unmuted. The red LED will illuminate when the
Channel is muted. When the “MUTE” LED is OFF, then the related Output Channel is UN-MUTED.
A momentary push of the 1, 2, 3, 4 , 5 and 6 buttons enters the Editin Menu for the Output
Channels (see later for the Output Channel Editin details). The blue “EDIT” LED will now be ON.
• DLM26 Menu and Sub-Menu Structures
As stated above, the start-up default screen is the followin factory preset:
From this point, sub-menus are accessed usin the UTILITY”, “A/B”, “1/2/3/4/5/6”, “ENTER” and
“ESC” buttons and all parameters and values are navi ated by the “NAV/Param.1”, “Param.2” and
“Param.3” encoders. Please refer to the followin menu structures:

The “Routin Options” pa e allows you to select the desired Input type:
By pressin ENTER on Input Routin and then rotatin the “Param.2” or “Param.3” encoders,
it is possible to select the Main Inputs for the DLM26, allowin the User to choose between
Analo or S/PDIF Di ital.
The selection can be confirmed by pressin the “ENTER” button.
The followin screen shows that the Analo Input has been selected:
−Power-On Procedure: this ives you the ability to select the option that will apply when the
DLM26 powers up after bein switched on:
By pressin ENTER and rotatin the “Param.2” or “Param.3” encoder, it is possible to choose
between two options: ”Fade In On” or “Fade In Off”.
The currently runnin option will be displayed with an asterisk to the ri ht of the option
description.
To chan e the option simply ENTER on the option not displayin the Asterisk and that option
will become active and an Asterisk will now appear to the ri ht of the option description.
The followin two options are available:
FADE-In = Off... when the DLM26 is turned on all Outputs re ard of their status before the
Unit was switched off, will be MUTED or UNMUTED automatically, meanin the DLM26 will
have no active Outputs or active Outputs, durin the start-up process, dependin from the
Outputs' previous status.
FADE-In = On... when the DLM26 is turned on all Outputs not previously muted before the
Unit was switched off will be active, meanin the DLM26 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 followin :

−Delay Time/Distance: this pa e allows you to select the measurement unit to be used for
the Delays: Time (in milliseconds “ms”) or Distance (in meters “m”):
By pressin ENTER and rotatin the “Param.2” or “Param.3” encoder, it is possible to select
the measurement unit to be used for the delay, which will be confirmed by pushin the ENTER
button.
The followin screen shows the selected delay measurement is Time (milliseconds)
−Ramps on changes: this pa e allows you to activate or de-activate Fadin -in and Fadin -out
ramps on the input/output volumes when any parameter chan es:
When connected to the DLM26 by the PC remote control software, it is possible to request
sudden parameter chan es where the difference between the old parameter and the new one
can cause unwanted “click” noises (bi differences in volume chan es) or “bumps” (bi
differences in Hp/Lp filters cuttin frequency values) as the DSP reconfi ures.
The Fadin -In and Fadin -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” durin live performance.
The followin screen shows the Fadin ramps function is Off and therefore de-activated:

If NO USER PRESETS are stored yet, the screen will show the followin :
If presets have previously been stored by the user, anyone of them can be recalled:
By usin the “Param.2” or “Param.3” encoder it is possible to scroll throu h the stored
presets. Once the desired preset appears on the screen select it by pressin the “ENTER”
button and this will force the DLM26 to be in to load this selected preset and the followin
transitory screen will appear:
Once loaded the DLM26 will exit to the “Recall a Pro ram” screen automatically and the above
screen will disappear:
Note: at any time it is possible to quit the recall action by pressin the “ESC” button.

−Save a Program: this pa e allows you to store a new preset in the DLM26’s memory:
By pressin the ENTER button and rotatin the “Param.2” or “Param.3” encoder, it is possible
to scroll throu h the previously saved presets and the available empty locations (identified by
“Empty Memory”).
If no user presets are stored, the “Save a Pro ram” screen will show empty memory locations
for all 1-64 presets as shown in the example below for location 10:
When storin an edited confi uration for the DLM26, select the location for a preset from the
64 available by usin the “Param.2” or “Param.3” encoders.
Once the desired location appears on the screen press ENTER a ain to reach the “Set
Program Name” pa e.
In this pa e the User can enter a Preset Name (up to 16 Characters) by usin the “Param.2”
or “Param.3” encoder to choose a character and the “NAV/Param.1” encoder to move between
the 16 available locations for the character’s positionin .
The current position of the cursor is shown by a “blinkin underscore”.
The followin is an example of a screen while enterin the preset name “Sta e 1 2x2” in
location 10:
To store the Preset Name press the “ENTER” button a ain.
The above action will take you to the “Enter to Save” pa e showin the selected location for
the preset and the final edited name:
Pressin “ENTER” a ain, will store the preset in the selected location with the chosen name
and the followin transitory screen will appear on the LCD:

described storin process..
Note: at any time it is possible to quit the storin action by pressin the “ESC” button.
−Delete a Program: this pa e allows you to delete a preset already stored in the DLM26
memory:
By pressin the ENTER button and rotatin the “Param.2” or “Param.3” encoder, it is possible
to scroll throu h the previously saved presets and the available empty locations (identified by
“Empty Memory”).
If no user presets are stored, the “Delete a Pro ram” screen will show empty memory
locations for all 1-64 presets as shown in the example below for location 10:
If Presets are available they will be shown in the “Delete a Pro ram” pa e as follows:
By usin the “Param.2” or “Param.3” encoder it is possible to select a preset to be deleted.
Pressin the “ENTER” button on a selected preset will brin up the “[Enter] to Delete.” pa e
