1. INTRODUCTION
Thank you very much for the confidence you have placed in
us by purchasing the EUROLIGHT LC2412. You now own an
outstanding, ultra-compact light mixing console, that features
the state-of-the-art digital DMX512 control. In addition, your
LC2412 is equipped with an analog output which allows to use it
virtually in every environment you can think of. The design of the
LC2412 (how it operates and how it is programmed) was
constructed with controlling dimmer packs and standard
spotlights in mind. To optimally use multi-function spotlights such
as scanners and moving heads, you should use control
consoles specifically created for this purpose.
This users manual is designed to give you an overview of all
the controls, so that you get to know all possible applications the
LC2412 offers. General safety instructions are followed by a
structured overview of the control panel. Afterwards, all functions
of your LC2412 are described in detail.

we have arranged them in groups according to their function. If
you need to know more about specific issues, please visit our
website at http://www.behringer.com.
1.3 General features and functions
LC2412 means: 24 preset channels and 12 memory channels.
But thats hardly all: You can simultaneously control 78 dimmer
channels via the DMX512 digital interface (26 console channels
x 3 DMX channels). And because several light units can be
operated on a single dimmer channel, this console gives you a
plethora of mixing possibilities.
1. NTRODUCT ON

EUROLIGHT LC2412
Comparable to a mixing console in a recording studio, a light
mixing console is a switching central for stage lighting. Therefore,
a light mixing console has to be absolutely reliable and under no
circumstances leave you stranded. We created our LC2412 using
the most modern components in order to guarantee you the
maximum reliability possible.
But without functionality, no amount of reliability is of use to
you. Thats why we integrated a tremendeous number of func-
tions in an extremely compact unit. You have always full control
of the light conditions, regardless whether you run the light show
at a live concert, a club or on a stage. To enable you complete
control over the current setup, the EUROLIGHT LC2412 has an
intuitive design structure and features a large number of LEDs
and a large LCD display.
A light mixing console is basically a controlling unit that
comprises a full system once it is integrated with a power source
and light elements.
Two different standards have established themselves in the
field of light control (analog controlling with 0 to +10 V and digital
controlling via the DMX512 control protocol). Your LC2412 is
compatible with both. The extent of controlling your lighting
situation can range from simply fading lights in and out, all the
way to configuring and programming entire light shows. You
can manually control the speed at which a program runs, enter
the desired speed into a preset for each step, or let it be
automatically determined by an internal beat generator. On the
other hand, you can control this beat generator by using a fader,
or let your musical program directly determine the beat for the
lighting setup.
Presets
Complex lighting situations can be set up using single faders
(each controlling up to 24 channels, whereby up to 72 single
dimmers can be controlled). You can light up individual channels
at full blast independently from their fader position using the
FLASH keys.
Mem ries
Presets can be stored into ten separate preset banks (with
twelve memory slots each), and can also be individually recalled.
All memories can be archived by using separate PCMCIA memory
cards.
Chases
The expression Chases refers to situations in which
individually programmed light steps (up to 99 steps) are executed
in succession (the lights chase each other). These steps can
be both individual presets as well as memories.
You can create extremely complex chases. For example,
parameters such as fade-in speed of a step, chase sequence
speed and their control via the built-in beat generator or music
can all be programmed.
Cr ssfade
There are several ways to alternate between various stored
or newly developed lighting situations. Conversely, you can also
alternate back and forth between individual steps of a single
chase manually or automatically.
Preview
With this function, you can preview stored memories or chases
without these being visible on the stage. This way, you can
discretely control the next step before letting it be seen on the
stage.
S und t light
This function is more widely known as party light. It basically
means that your music drives the light show. An incomming
music signal is broken down into three frequency ranges (bass,
mids and highs), each of which is assigned to a (memory) channel.
Depending on the volume of the respective signal segments, the
lights assigned to them will shine accordingly. You can even
program a setup for song pauses.
MIDI
The LC2412 can be controlled via MIDI. Two EUROLIGHT
LC2412s can be operated as master and slave by using the MIDI
interface. Entire shows can be stored and recalled by means of
a MIDI sequencer.
DMX512
The DMX digital protocol lets you flexibly assign 78 of the 512
digital channels to individual light console channels (s ftpatch).
Mem ry card
The EUROLIGHT LC2412 offers you access to 120 storable
lighting setups (memories) that can easily be altered. A virtually
unlimited archive of lighting setups can be created by using the
interchangeable memory cards on which these setups are stored.
The sky is the limit when you put your creativity to the test with
the 99 programmable chases, each consisting of 99 single steps.
2. CONTROL ELEMENTS
The control panel of your LC2412 is divided into various areas
with different functions. The way the controls on the LC2412
were designed makes using the unit and capturing current
settings a breeze. The control elements are described on the
following pages according to the functions they play. If parts of
the unit are shown in light grey in an illustration, that means that
these controls belong to another section (described elsewhere
in the manual).
All control elements and function keys are provided with control
lights to enable you full oversight of the setup/functions currently
selected.
The sections: A PRESET section, B MEMORY-
section + bank display, sound to light, FLASH keys,
programming section, MAIN section, CHASE
section.
The LC2412 also has additional functions that cannot be
assigned to a particular section (special channels):
SPECIAL 1 key. Used to activate a special channel, for
example for turning a fog machine on/off.
SPECIAL 2 key. The same function as SPECIAL 1 key. Just
like in the case of other channels, three DMX channels can
be assigned to these two channels (i.e. to SPECIAL 1/2).
Both special channels are then labeled as channels 25 and
26 on the console. SPECIAL 1 and SPECIAL 2 keys can be
programmed as switches, keys or kill keys. Additional
information on this subject can be found in chapter 7.3.
POWER switch. Used to power up the EUROLIGHT LC2412.
The POWER switch should always be in the Off position
when you connect the unit to the mains.
+Please take n te: Merely switching the unit ff d es
n t mean that it is fully disc nnected fr m the
mains. When n t using the unit f r pr l nged
peri ds f time, please unplug the units p wer
c rd fr m the p wer utlet.
The BNC connector is used for connecting a gooseneck
lamp (optional).
2. CONTROL ELEMENTS

EUROLIGHT LC2412
2.1 Control elements of the A PRE ET section
Fig. 2.2: A PRESET section ( etail)
Faders 1-12. Used to set the intensity of light elements
connected to the dimmer pack.
UPPER switch. When you press this switch, the A PRESET
section is switched to the twelve additional channels. After
that, you can set up the intensity of channels 13 - 24. See
also chapter 3.2.
Setting up presets
Channel faders are used for setting up a preset that can be
directly recalled by moving fader A . As in all other setups,
the MAIN fader (see chapter 2.6) determines the maximum
illumination level of selected light sources.
2.2 Control elements of the
B MEMORY section
The faders of the B MEMORY section are located in the block
underneath the A PRESET section.
These faders control the illumination level of an entire group
of channels in a ratio to one another that you previously
determined by setting up the A PRESET faders and saving
this setting as a memory.
Fig. 2.3: B MEMORY section
Exception: When the LC2412 is in preset mode (P shown in
the bank display), the faders control the same channels as the
faders of the A PRESET section. This way, you can simul-
taneously create a second preset.
- These faders are also a part of this section, but they
have a double function. When the LC2412 is in sound to
light mode (party light function), they control the illumination
level of individual memories assigned to particular frequency
ranges.
The BANK display shows the storage bank to which the
memories you recall belong. It also shows if the LC2412 is
currently in preset mode (P diplayed). The display starts
flashing when you switch into preset mode, and lights up
constantly after three seconds. The preset mode is active
only after the flashing has stopped. This prevents accidental
activation of the preset mode as well as rough fades.
Fig. 2.1: Section overview
2. CONTROL ELEMENTS

8
EUROLIGHT LC2412
UP/DOWN keys. Use them to select a preset bank (0 - 9)
or switch into preset mode (P). The control lights flash
when you select a new bank while memories from the
previous bank are still active (the fader(s) is(are) pulled
up). Pull the fader(s) ( , -) down to fade the
memory out. When you pull the fader(s) up again, the
memory of the new preset bank is visible on the stage
(also see chapter 4.1.2).
SOUND TO LIGHT key. See chapter 2.3.
PREVIEW key. It gives you the option to preview (or modify)
stored memories one more time before implementing them
on the stage. This is particularly useful when you saved
chases as memories and wish to double-check and/or
modify their speed before integrating them into a running
show. When preview is activated, the chases are shown
on control LEDs exclusively.
Each fader is assigned to a FLASH key (section ). This key
is used to assign a specific bank position to individual presets
while programming a memory.
2.3 Control elements of the
OUND-TO-LIGHT section
The SOUND-TO-LIGHT controls are located in the right-hand
section of the B MEMORY section.
If the sound-to-light function is active, memories 9 - 12 are
controlled by a music signal, whereby the volume of the signal
dictates the illumination level of the memories. The music signal
is divided into three frequency ranges (bass, mids, higs). One
memory slot is assigned to each of the three frequency ranges.
For optimal results, please put the faders to the middle position.
This will let you bring individual settings of memories into sync
with one another, should the levels vary from memory to memory.
Fig. 2.4: The SOUND-TO-LIGHT section
The PAUSE fader is, just like the fader , used primarily
to control the illumination level of memories. If the sound-to-
light function is active, it controls a memory slot assigned
to run during program breaks between two musical pieces.
The BASS fader takes over the basic configuration of the
illumination levels for the memory slot assigned to the bass
portion of the frequency range.
The MID fader is conversely assigned to the mids.
The TREBLE fader is conversely assigned to the highs.
and : Bank display and UP/DOWN keys, see chapter
2.2.
The SOUND-TO-LIGHT key activates the sound-to-light
funtion.
The music signal necessary for controlling the show can be
fed into the ANALOG INPUT connector located at the rear of the
LC2412.
2.4 ection : FLA H keys and OLO
Fig. 2.5: The FLASH keys
FLASH keys. Pressing one of the FLASH keys sets the
respective channel to the maximum illumination level set on
the MAIN fader, independent from its own fader position.
For this purpose, the CH FLASH key has to be pressed.
The channel flash function is automatically activated in
preset mode.
Dual-function FLASH keys. Memories or chases can be
stored to memory positions 9 - 12 (chase to memory).
When a respective storage bank is selected, chases are
indicated with yellow LEDs. Chases can also be recalled
by using the FLASH keys.
S l
When the solo function is simultaneously active (SOLO key
, LED lit), all other emitters or light elements are deactivated.
Only the channel selected via the FLASH key is still active.
2.4.1 Disabling the solo function
You have the option to exclude specific channels from the
solo function, so that these channels remain active even when
Solo is activated.
Disabling solo is achieved by performing the folloing
programming sequence:
1. Press UTILITY 1 .
2. Select the option DISABLE SOLO by using the SOFT A key
located below the display. The channel for which the
solo function should be disabled or enabled is shown in the
top left section of the display. The respective disabled/
enabled status of the said channel is indicated to the right of
the channel number itself.
3. To select the channel you wish to adjust, turn the DATA
wheel . The desired channel can also be selected by
using the FLASH key (for channels 13 - 24: first press the
UPPER key).
4. SOFT B selects DISABLE and thus disables the solo
function for this channel SOFT A selects ENABLE.
5. To exit this procedure, press the QUIT key , thus
confirming the procedure.
+When y u disable the s l functi n f r a particular
channel, the channel remains active in case when it
is part f an activated mem ry that fades after
pressing ne f the FLASH keys.
Example:
You have disabled the solo function for channel 8. The light on
channel 8 remains lit if you press one of the FLASH keys, as long
as the solo function is active.
Previously, you have programmed a memory that uses channel
8. The memory has just been activated on the stage. Now, press
one of the FLASH keys (CH FLASH is also activated). There
are tw lights on the stage, i.e. channel 8 and the channel
activated with the key!

2.5 Control elements of the
programming section
Despite its compact size, the EUROLIGHT LC2412 is a versatile
light mixing console. In it, we have integrated a plethora of
functions, among others, various functions for memories, chases
and digital control. The basic elements of the programming section
are located at the top right section of the unit. To let you quickly
orient yourself in difficult situations, the LC2412 also features a
display.

procedure functions in particular is explained in greater
detail in chapter 4.1.
CHASE key. Used to initiate the programming procedure
(intended for creating a chase). How this is done is
explained in chapter 6.1.
The CTM key (stands for chase to memory) brings up the
menu for storing chases. Basically, you can store
completely programmed chases into memory. Each of the
ten memory banks has four memory slots (9 - 12) available
for this purpose.
UTILITY 1. This key takes you to the following programming
menus: DISABLE SOLO, SELECT CURVE and THEATRE
MODE.
UTILITY 2. This key takes you to the following programming
menus: DMX PATCH, SELECT MIDI and SELECT SPECIAL.
Further information about these functions is to be found in
chapters 7 and 8, ADDITIONAL FUNCTIONS OF THE
LC2412 and DIMMER CONTROL.
LIVE key. By pressing this key, you can route chase or
memory steps to the consoles output in order to see what
it would all really look like on the stage. This also makes
sense for the programming procedure itself, because
chases are for example only shown on the LEDs during
their selection (normal setting, blind mode). This way,
selecting chases is even possible while a program is
running on the stage, without disrupting the program itself
(automatic preview). The live mode changes everything
the other way around: only the settings observed in the
preview function are visible on the stage.
SOLO. The solo function utilizes the FLASH keys. When
the solo function is active, pressing the FLASH key for a
single channel/memory completely dimms all other lights. If
so desired, individual channels can be taken out of the solo
functions reach (see chapters 4.3.1 and 2.4.1).
CH FLASH key. Switches the channel flash function on
and off. When the channel flash function is on, you can
use the FLASH keys ( +) to enable the highest
illumination level on individual channels. This function is
automatically activated in preset mode (see chapter 3.1.1).
However, it has to be manually activated in memory mode.
UPPER switch. Used to switch over to channels 13 - 24.
See also chapters 2.1 and 3.2.
CONTRAST control. Turning this pot lets you adjust the
display contrast.
PROGRAM display. Depending on the programming
procedure, different menues are shown here. If you havent
programmed anything yet, or if you have quit a programming
procedure by means of pressing the QUIT key , the
display shows the current chase and the respective step
(basic setup).
DATA wheel. Used to change/select programming
parameters. For example, it can be used for programming
chases, during which you dial in steps and determine their
execution speed. Besides, it is also used for directly calling
up chases (see also chapter 6.2).
SHIFT key. Opens additional programming menues. A more
detailed explanation can be found in the description of the
respective programming procedures.
SOFT A key. Needed for selecting items while in a
programming menu. The menu texts and the SOFT A key
are ordered in such a way that this key lets you select the
options above (appearing in the menu).
SOFT B key. Has the same function as the SOFT A key.
QUIT key. Used for closing a programming procedure and
going back to the main menu.
2.6 Control elements of the main section
Fig. 2.7: The main section
Control elements that apply to function groups or the entire
console are grouped in the main section.
A fader. This fader is the master fader for the A PRESET
section it determines the maximum illumination level of the
entire section. The FLASH keys ( / as well as /
) can still be utilized, even when the fader is at its zero
position.
B fader. This fader is the master control for the B MEMORY
section it determines the maximum illumination level of all
memories. Just like in the case of the A fader, the FLASH
keys can be utilized even when the fader is at its zero
position.
When the MAIN fader is raised up, both of these faders
(A and B) can be used to fade in and out between the
settings of both of these sections.

EUROLIGHT LC2412
MAIN fader. It determines the maximum illumination level of
all commands at the consoles output.
PRESET FLASH key. You can execute the entire A PRESET
section with this flash key, that is, activate the A PRESET
section on the stage, even if the the A fader is fully
down. As soon as you let go of the key, the lights fade
again. More information about this subject is found in
chapter 4.3.
MEMORY FLASH key. Has the same function for the B
memory section.
Also, two additional keys in this section affect the entire console
output:
HOLD key. Freezes the current settings, while you select
a new preset, recall a different memory or implement an
entirely different configuration. This procedure is described
in chapter 7.2.
BLACKOUT switch. Completely dimms all lighting elements.
This function affects the entire console output, that is, it
also affects the chases. The dimming is done abruptly. If
you want the dimming to take place softly, use the MAIN
fader. Console settings can be altered while the console
output is deactivated. To illuminate the stage again, hit the
BLACKOUT key again. The control LED dies out.
2.7 Control elements of the chase section
Fig. 2.8: The chase section
NUMBER key. Selects a chase, enabling you to show
individual chases on the control LEDs (automatic preview).
The control LED of the NUMBER key lights up, as long as
chases are active in any form. This means, the LED lights
up even when the chase is not active, but just dialed in,
ready for action. When you select a chase whose steps
have still not been programmed, the LED dies out after
letting go of the key. The LED also dies out when the CHASE
fader is pulled down.
INSERT key. Activating this key while a chase is running
lets you alternate between the current step and the one
preceeding it by pressing the STEP key . This function
can also be executed utilizig the X-FADE control (MANUAL
MODE key activated). Additional information on this
subject can be found in chapter 6.2.6.
CHASE fader. Controls the illumination level of a complete
chase setup. Separate ratios of a memory incorporating
this chase remain intact.
X-FADE control. Used to manually dissolve between
individual chase steps. Can also be used to dissolve
between memories. Additionally, fade-in speed of chase
steps can be configured, provided this speed was not
already determined in theatre mode (only when theatre
mode is active). More detailed information on this subject
can be found in chapters 6.2.3 and 7.4.
SPEED fader. Controls chase speed.
STEP key. Manually triggers chase steps. This can also be
done while chases are already active. This function can
also be remotely controlled by using a footswitch.
MANUAL MODE key. Assigned to the X-FADE control. When
the MANUAL MODE key is activated, turning the X-FADE
control back and forth either fades back and forth between
two chase steps (INSERT key activated) r fade chase
steps in after one another (INSERT key deactivated). A
more detailed overview of the various possibilities of fading
in/out can be found in chapter 6.2.4.
SOUND/RUN MODE key. Selectively activates chase
control by means of bass rythm (SOUND) r by means of
the internal speed control (RUN).
2.8 Rear panel connectors of the LC2412
Fig. 2.9: Digital an analog outputs
DMX512 OUT connector. The digital output of the LC2412
is provided by means of a 5-pole XLR connector. You can
connect a dimmer pack. It can be used to process digital
control commands according to the DMX512 control
protocol.
ANALOG OUT connector. The analog output is meant for
controlling via the analog standard (0 to +10 V DC) and is
implemented as a Sub D connector. Used to connect dimmer
pack that dont use the modern DMX512 control protocol.
Fig. 2.10: A itional back-panel connectors
MIDI OUT connector. MIDI data can be forwarded from the
MIDI OUT connector to a second LC2412 or another MIDI
sequencer/PC by using a corresponding cable (connect it
to the MIDI IN connector on the receiving unit). This lets you
control two consoles in parallel, that is, a total of 156 DMX
channels are at your disposal.
MIDI IN connector. Used to feed in MIDI data (e.g. from a
MIDI sequencer or another LC2412) to control the LC2412.
ANALOG IN connector. Connect an output of your mixing
console, your CD player or another analog signal source to
this 1/4" TS mono jack connector. This lets you use the
sound-to-light function and musical control of chases.
FOOTSWITCH connector. Connect a footswitch here to
remotely control the STEP key. Additional information about
this subject can be found in chapter 6.2.4.
