3 Applications
The moving head MINIZOOM-712 is a spotlight
rotating around two axes (pan / tilt) . It features a
motor-controlled zoom function and is used for
effect illumination, e . g . in function rooms, on
small stages . As a light source, it uses seven 12 W
RGBW LEDs which are able to project coloured
and white light .
The unit is designed for operation via a DMX
light controller (8 or 16 DMX control channels);
however, it can also be operated without a con-
troller, either independently or in combination with
multiple MINIZOOM-712 spotlights (master /slave
mode) .
4 Setting Up / Installation
•
To prevent heat accumulation inside the unit,
always position the unit so that sufficient air cir-
culation will be ensured during operation . Never
cover the air vents of the housing .
•
Always keep a minimum distance of 50 cm to
the illuminated surface .
Set up the unit on a solid, flat surface . Alternatively,
install it upside down on a lighting stand system
(e . g . crossbar) by means of the mounting bracket
(8) provided: Use the two hexagon socket screws to
fasten the bracket to the centre of the base plate,
and then use a suitable support (e . g . C hook) to
install it on the lighting stand system .
WARNING Install the unit safely and expertly .
When the unit is installed at a
place where people may walk or
sit under it, additionally secure it:
Screw the eyebolt (7) provided
into the threaded hole of the base
plate . Then attach a safety rope to
the eyebolt so that the maximum
falling distance of the unit will not
exceed 20 cm .

5 Control Connections
The MINIZOOM-712 is equipped with 3-pole XLR
control connections (4): a DMX input (DMX IN) and
a DMX output (DMX OUT) .
The units to be controlled are connected in a chain
to the unit sending the control signals . For connec-
tion, use special cables for DMX signal transmis-
sion (e . g . cables of the CDMXN series from IMG
STAGELINE) . For a total cable length exceeding
150 m or when controlling more than 32 units, it
is generally recommended to insert a DMX level
matching amplifier (e . g . SR-103DMX from IMG
STAGELINE) .
5.1 Connection to a DMX controller
To connect multiple DMX-controlled units to a DMX
light controller (fig . 4), proceed as follows:
1) Connect the DMX output of the controller to
the DMX input of the first DMX-controlled unit .
2) Connect the DMX output of the first DMX-con-
trolled unit to the DMX input of the second
DMX-controlled unit . Proceed in the same way
to connect the output of the second unit to the
input of the third unit etc . until all DMX-con-
trolled units have been connected in a chain .
3) To eliminate interference in signal transmission,
in case of long cables or a multitude of units
connected in series, terminate the DMX output
of the last DMX unit in the chain with a 120 Ω
resistor (> 0 .3 W): Connect a DMX terminating
plug (e . g . DLT-123 from IMG STAGELINE) to the
output jack .
