LED-4MC will also be able to operate spotlight combi-
nations with a common control (e. g. PARL-40SET) or
LED panels (e. g. RGBL-110DMX) if they allow suc-
cessive control of the individual spotlights or segments
via the channel diagram above (spotlight / segment 1:
channels 1 – 4, spotlight / segment 2: channels 5 – 8,
etc.).
The controller will be able to create static scenes, i. e.
fixed colours or colour combinations and changing
scenes (sequences). The scenes of a sequence will
change after a preset time or by music pulses via the
integrated microphone. A selector switch is provided to
define if a combination of 3 or 4 spotlights is used. In
addition, a blackout function and a stroboscope effect
will be available.
4 Setting the Controller in Operation
4.1 Connecting LED spotlights
Connect the output (1) of the controller to the DMX
input of the first RGB LED spotlight.
For connection, special cables for high data flow
should be used. Standard microphone cables with
screening and a minimum cross section of 2 × 0.22 mm
and with a capacity as low as possible can only be rec-
ommended for a total cable length of up to 100 m. For
cable lengths exceeding 150 m it is always recom-
mended to insert a DMX level matching amplifier (e. g.
SR-103DMX by "img Stage Line").
Connect the DMX input of a second spotlight to the
output of the first spotlight. Connect the third spotlight
to the output of the second spotlight etc. until all spot-
lights have been connected in a chain.
For interference-free operation, terminate the out-
put of the last spotlight with a 120 Ω resistor (> 0.3 W):
Solder the resistor to the pins 2 and 3 of an XLR plug
and connect the plug to the DMX output or use a
corresponding terminating plug (e. g. DLT-123 from
"img Stage Line").

4.2 Setting the number of spotlights
With the switch 3-MODE-4 (2), define if 3 or 4 spot-
lights have been connected. Accordingly, select the
position "4" for controlling PARL-40SET or "3" for con-
trolling RGBL-110DMX.
The setting will only affect the type of sequence pat-
tern (e. g. running light).
4.3 Setting DMX addresses
When using individual spotlights, set the following
DMX start addresses on these spotlights:
First spotlight:
Second spotlight: start address 5
Third spotlight:
Fourth spotlight:
To synchronize further spotlights, set these spotlights
to the same start addresses.
4.4 Connecting the power supply
Connect the plug-in power supply unit provided to the
low voltage jack DC IN 12V (3) and to a mains socket
(100 – 240 V~/50 – 60 Hz). To prevent accidental dis-
connection, the plug will latch in the plug. When insert-
ing the plug, hold it in such a way that its "ears" fit into
the lateral recesses of the jack. After inserting, turn the
plug clockwise by 90° to latch it.
5 Operation
Switch on the controller with the switch ON / OFF (4).
After switching on, the controller will have the last set-
ting selected, provided that this setting existed for a
minimum of 3 seconds before the controller was
switched off.
5.1 Static colours
1) If the LED "SCENE" below the button MODE (8)
does not light up, press the button so that the LED
will light up.
2
2) If one of the functions B / O or STROBE is active [the
LED below the button (12 or 13) will light up], deac-
tivate it with the corresponding button.
3) Press the button COL (11) [repeatedly] to select the
desired colour or colour combination.
5.2 Sequence mode
1) If the LED "SCENE" below the button MODE (8)
lights up, press the button so that the LED will be
extinguished.
2) If one of the functions B/O or STROBE is active [the
LED below the button (12 or 13) will light up], deac-
tivate it with the corresponding button.
3) Press the button PTN (7) [repeatedly] to select one
of the preset sequence patterns (e. g. running light).
