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:
DLM26
Speaker Management
and a status bar will show the progress of the DLM26 initialization process:
DLM26
The DLM26 has three factory pre-set working 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 working
modes, or the last one selected prior to the unit being turned off.
First time activation will default to the first of the preset working modes.
DLM26
2x3 WAY X-OVER
•
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 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, A/B and 1/2/3/4/5/6 buttons
The UTILITY button allows the User to enter the Sub-menus and set the general characteristics of
the Processor. The A and B buttons allow the User to enter the Editing Menus of the Processor's
Input Channels and buttons 1, 2, 3, 4, 5 and 6, allow the User to enter the Editing 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 Editing Mode for the Input Channels (see
later for the Input Channel Editing 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 Editing Menu for the Output
Channels (see later for the Output Channel Editing 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 following factory preset:
DLM26
2x3 WAY X-OVER
From this point, sub-menus are accessed using the UTILITY”, “A/B”, “1/2/3/4/5/6”, “ENTER” and
“ESC” buttons and all parameters and values are navigated by the “NAV/Param.1”, “Param.2” and
“Param.3” encoders. Please refer to the following menu structures:

HPF sub-menu [Standard Filters]– from the sub-menu page, using the Param.2 encoder, it is
possible to set the HPF in Bypass or as one of the 8 Standard Filters: Buttw_1st, Buttw_2nd,
LRiley_2nd, Bessel_2nd, Buttw_3rd, Buttw_4th, LRiley_4th, Bessel_4th.
The following is an example of a HPF sub-menu screen with the filter set at 400Hz as 24dB

Here, the NAV/Param.1” encoder will increment/decrement the Frequency value by step of one
thousand Hz, the Param.2 by steps of one hundred Hz and the Param.3 by steps of one Hz.
HPF sub-menu [Custom Filters]– from the sub-menu page, using the Param.2 encoder, it is
also possible to set the HPF as “Custom Filter”, where this means that the HPF is builded as
cascade of IInd Order Cells, which number is depending from the filter's order and where for each
Cell can be set independently the Low Cut frequency and the Q.
More precisely, the available independent parameters for setting are the following:
1.
2.
3.
Custom_2nd: builded using 1 IInd order Cell, where Low Cut Frequency and Q can be set
Custom_3rd: builded using 2 IInd order Cell, where Low Cut Frequency can be set on both
the cascaded Cells and the Q on the second one
Custom_4th: builded using 2 IInd order Cell, where Low Cut Frequency and the Q be set

The number of accessible IInd order Cells is depending from the Custom Filter order: Custom_2nd
will allow the editing of just one IInd order Cell, Custom_3rd and Custom_4th, the access to 2
IInd order Cells.
In the previous example, rotating Clockwise the NAV/Param.1 encoder, we can access the Filt1

When operating in Custom mode, depending from the chosen mode, a couple of Odd and Even
Outputs (as Ch1/Ch2 or/and Ch3/Ch4 or/and Ch5/Ch6) are “coupled” so to get a single “Full
Band” MONO output on the Odd channel of the couple, and for this output a 2 bands Rms
compressor and Peak Limiter is available.
The available configurations in Custom Mode are the following:
3 DCL........... where 3 Outputs are available (Ch1/Ch3/Ch5), each one “Full Band” and
performing a 2 bands Rms Compressor and Peak Limiter, where the splitting frequency of the 2
bands can be custom selected:
− Outputs 1 [5 Bands Eq +2Bands Rms Compressor + 2 bands Peak Limiter]

 Input and Output Channels Last Edited Parameter Return Function
Once you have escaped out of parameter editing within the individual Input or Output channels
the DLM26 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.

Input Channels and output Channels LINK Function
The DLM26 is able to perform a unique LINK MODE between Input Channels as well as a link
between Output Channels to enable quick and immediate editing (you cannot link output to input
channels).
To link channels when editing, you will need to select a “Master” channel that will be the one to be
edited and have it’s parameters displayed on the LCD screen. You can then select and link other
channels (Slaves) that you wish to apply the same changes to.
To enter a link mode session, select the Master channel Edit mode, then link the Slaves by
pressing their related Edit buttons.
All Linked channels will be selected ready for adjustment when their “Blue” LED is lit in the Editing
mode.
Now all Slave channels and only those selected will modify their parameters accordingly as you
edit the Master channel.
All other existing parameters will stay the same within the Slave Channels 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 Output channels 1/2/4, we can enter the editing mode of
Output Channel 1 by pressing the related Edit button and turning on the Blue LED below the
Output Channel 1 LED meters. This assigns the “role” of Master and displays this channel’s
parameters on the LCD:
Out-1
Name
Limiter
A: 5ms R: 0.2s +5.0dB
Then press the Edit button of Output Channels 2/4, turning on their related “Blue” LED’s. Now all
parameters edited on Output Channel 1, will also be applied to channels 2 and 4.
If we want to remove one of the linked channels 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 Output Channels
you jump across to begin editing an Input channel or vice avers.

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 DLM26 and
return the device to the original factory setting, is available to the user.
Note: Continuing with this process will mean the DLM26 will re-initialize to the original factory
settings and any previously stored information and changed parameters will be permanently lost.
Note1: Together with the all information, also the current password will be lost after a “Factory
Reset” and will be replaced with the Factory one: “000000”.
In case the customer forgot the password and need to reinitialize it, can use the “Factory Reset”
to put the Password at its original “000000” value.

Release the buttons and wait for the DLM26 to re-initialize.
Once completed, the DLM26 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 DLM26 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 - Actually can happen that sometime 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, 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 DLM26

USB/RS485 Remote Control protocol for Presets Changing and Gain/Volume
controls
The following is the HEX Code for controlling the DLM26 recall presets and master volume control:
Preset Changing:
CMD_RECALL_PRESET: CMD=1BH
A. The User has to send the following Command, including the number of the preset to load on
the unit:
TX:
STX
ID_M
ID_N
CMD
D0
D1

F7H
XX = 0,..,31 (ID device)
Npreset=0,...,64 Preset number
The DLM26's microcontroller will check if the Preset is initialized (available or not yet created...)
B. If YES, then the microcontroller will send back to the User (eg Crestron/AMX Remote Control..)
the same frame used by the command
RX:
STX
ID_M
ID_N

So in this case, if the user gets back EXACTLY what was sent, the preset is existing and loaded on
the unit.
C. If the preset that the user wanted to load is NOT YET INITIALIZED (not yet created, so not
available...). the microcontroller will notify that to the user, sending back the following frame:

Input Gain and Output Volume Control:
UPDATE GAINS-PHASE: CMD=01H
A. The User has to send the following Command, including the value to be assigned to “Vol”, for
modifying the Input Gain (Chn = 0, 1) or the Output Volume (Chn = 2, 3, 4, 5, 6, 7).
Also the Output signal Phase can be modified:

XX = 0,..,31 (ID device)
Chn=0,...,7: Channel selected, 0, 1=In1, In2; 2,...,7=Out1,..,Out6; when Channel 0, 1 selected, then Vol=Input
Gain, when Channel 2, 3, 4, 5, 6, 7 selected, then Vol= Output Vol.
Phs= Phase only if the Chn>1; Value=0, 1 where 0=direct, 1=inverse (180')
Vol= Gains from 0 to 180 (-12dB/ +6dB step 0.1dB)
B. If the command has been properly executed and the Gain/Volume modified, then the
microcontroller will send back to the User (eg Crestron/AMX Remote Control..) the same frame
used by the command:

More About Passwords....
We remind here the main points of the Password management form the Stand alone device, so to
let e4asier to access the further information related to an added Password Level accessible ONLY
through Pc Sw.
DLM26 -Stand Alone Password Management
−
On the DLM26 the only available Password is the “User Password” (set as “000000” as default)
and is allowing to lock or less the parameters' editing.
When the DLM26 is in “Lock” mode, then if the “Show parameter” option is set on “be
shown” the user can “see” the parameters' value but to modify it.
If the the option is set on “not be shown”, then the user can not see event eh parameters'
set value.
−
The user can set as he likes the Password, using the options of the “User Password”. Where to
access it need to first provide the currently set Password.
If not Password had been set previously, then the “000000” default Password will be the
“current” one.
−
If a “Super User” created presets through the Pc Sw and made them not accessible to the User
setting a “Super User” Password, then the final User will never be able to know the content
those presets if not having available the “Super-Password” (see below...).
DLM26 – Remote Control by Pc Sw Password Management
On the Remote Control Sw, several types of Passwords are available.
After “clicked” on the Key button, shown in the figure here below:
The Remote Control Sw will show the following screen:
Here depending from the provided Password, the User functions can be accessed or the SuperUser ones.
So, at the above screen, 2 Password can be provided:
−
−
Password User
Password Super User
1.
Password User (default = “000000”)
Once entered the Password User, click on the “OK” button and the following window will open
Then select the Lock or Unlock position and Confirm the choice through the “Confirm” button.
If the button is set on Lock, after confirming the sw will lock the all parameters both of Input and
Output channels.
If the button is set on Unlock, after confirming the sw will allow the access to the all parameters
both of Input and Output channels.
Same function is offered by the following button
but here it is not necessary to set any Password and it is available for a quick Lock/Unlock when
operating by Remote Control Pc Sw and it is not affecting the Pc setting when back to the Stand
Alone mode.
The Lock/Unlock mode set by the use of the Password, will be operative on the Stand Alone device
also when not operating through the Remote Control Pc Sw.
2.
Password SuperUser (Fix = “Suser1”)
Once entered the Password SuperUser, click on the “OK” button and the following window will
open
Then select the Enable or Disable position and Confirm the choice through the “Confirm” button.
If the button is set on Disable, after confirming the sw will not allow the “Lock/Unlock” function on
the parameters of single processes (in Super User mode, there is the possibility to Lock/Unlock
the access to the parameters of single processes...).
If the button is set on Enable, after confirming the sw will show a “lock” on top of the all
processes which parameters can be accessed or less (depending form the chosen Lock/Unlock
status), and this “focused” Lock/Unlock function is available ONLY on the Output channels.
The processes, which parameters can be Locked/Unlocked, are the following:
1.
2.
3.
4.
Hp,Lp or BandSplit (in Custom mode)
Peak Limiter
Rms Compressor
EQ filter1,...EQ filter5
Clicking on the Icon
the parameters of the related process will become hidden (if previously
visible), or visible (if previously hidden)
If , in example, the compressor's parameters are visible
after clicked on the Icon
the screen showing the compressor's parameters will become blank,
hiding the compressor's parameters themselves.
The same will be for the all parameters of the Lockable/Unlockable processes.
The all above setting can be stored as part of the presets, so being recalled once a preset is
loaded.
If the preset is containing parameters “locked” through the use of the Super User functions, these
parameters will be loaded ...locked.
When the Sw is launched, the Super Password mode is automatically disabled, so the final User,
unless knowing the Super User Password, will not be able to see/access the locked parameters
coming with the recalled presets.
The final User having Only the User Password will be able to lock/unlock just the “visible”
parameters and the ones left available by the Super User.
Because each Output channel can have a different number of locked parameters, if trying to link a
locked parameter with an Unlocked one (when using the Link Channels function), then the Pc Sw
will not allow the Link between the 2 parameters.
The Link Function is ONLY available when the DLM26 is operating in Standard Mode.
