INTRODUCTION
Thank you for purchasing the product MANTIS, PR-2021H.
This product manual contains important information about the safe installation and use of this projector.
Please read and follow these instructions carefully and keep this manual in a safe place for future
reference.
MANTIS adopts advanced procedure of design and manufacturing. The figure of housing is elegant,
lovable and portable, which features its special character compared with conventional luminaire. It is
convenient to hang the unit and the angle of the body is easy to be adjusted, and the projector even
can be carried by hand.
MANTIS complies to CE norms and standards and uses international protocol DMX 512. It can be
controlled by sound, auto programmes or a controller, and can be used as a stand-alone unit or linked
with each other for multi-units or linked to a controller, so it is suitable for many different applications.
MANTIS series have 5 types of products for your selection: PR-2021H-1, PR-2021H-2, PR-2021H-3,
PR-2021H-4 and PR-2021H-5. (There are some differences among them. For detail please refer to
“Technical Data” section)
You can get rainbow effect when the colour/gobo wheel rotates quickly. The projecctor has a device of
auto thermal cut-off. And the projector will switch off the lamp automatically after about 30 seconds of
shutter, so it can effectively prolong the life of the lamp.

damage caused by transportation, consult your dealer and do not use the apparatus.
The projector is for Indoor use only, IP20. Use only in dry locations. Keep this device away from rain
and moisture, excessive heat, humidity and dust. Do not allow contact with water or any other fluids, or
metallic objects.
The projector is not designed or intended to be mounted directly on to inflammable surfaces.
The projector is only intended for installation, operation and maintenance by qualified personnel.
The projector must be installed in a location with adequate ventilation, at least 50cm from adjacent
surfaces. Be sure that no ventilation slots are blocked.
Do not project the beam onto inflammable surfaces, minimum distance is 3m. 3m
Avoid direct exposure to the light from the lamp. The light is harmful to the eye.
Do not attempt to dismantle and/or modify the projector in any way.
Electrical connection must only be carried out by qualified personnel.
Before installation, ensure that the voltage and frequency of power supply match the power
requirements of the projector. Only use the lamp with the specified type and rating.
It is essential that each projector is correctly earthed and that electrical installation conforms to all
relevant standards.
Do not connect this device to any dimmer pack.
Make sure that the power-cord is never crimped or damaged by sharp edges. Never let the power-
cord come into contact with other cables. Only handle the power-cord by the plug. Never pull out the
plug by tugging the power-cord.
Never run the projector without a lamp.
Occasional breaks are necessary to prevent breakdowns.
There are no user serviceable parts inside the projector, do not open the housing and never operate
the projector with the covers removed.

INSTALLING THE PROJECTOR
This unit has been designed to be hung. Mount the bracket provided on the body of the projector.
There are 2 M8 knobs provided to tighten the body and the bracket. When you want to adjust the
angle of the body of the projector, you only loosen the two M8 knobs carefully and then adjust the
angle of the body. After finishing that, it is recommended that you don’t forget to retighten the two M8
knobs. Always ensure that the projector is firmly positioned to avoid vibration and slipping and always
ensure that the structure to which you are attaching the projector is secure and is able to support a
weight of 7.9kg for each MANTIS.
For safety the unit should have a secondary fixing with a safety cable through the two handles on the
back of the unit, and the safety cable should afford 10 times of the unit’s weight.
FITTING THE LAMP
Remove the lamp access hatch by loosening the 2 M4 screws.
Insert an EVC 24V/250W lamp in the lamp porcelain holder. (Note: Never touch new lamps with your
fingers; use a tissue or a cloth. Before removing blown lamp, ensure that the unit is sufficiently cool).
Mount the lamp access hatch again.
Retighten the 2 M4 screws.

POWER SUPPLY - MAINS
Use the plug provided to connect the mains power to the projector paying attention to the voltage and
frequency marked on the panel of the projector. It is recommended that each projector is supplied
separately so that they may be individually switched on and off. It is recommended that the
yellow/green power-cord must be earthed correctly.
OPERATION
The projector can be controlled by sound, auto-programmes or a controller, and can be operated in
Stand-Alone mode, Master/Slave synchro mode or Controller mode.
When the power is on, the projector will reset automatically for operation.
TO SET THE DIP SWITCH ADDRESS
Each projector has 10 switches with the numbers from 1 to 10, which may be set on the “ON” or “OFF”
position. You should set the DIP switches correctly to operate the projector. (See “Stand-alone mode”,
“Master/Slave synchro mode” and “Controller mode” for detail)
XLR CONNECTORS AND TERMINATOR
XLR CONNECTORS
Connection between controller and projector and between one projector and another must be made
with 2 core screened cable, with each core having at least a 0.5mm diameter. Connection to and from
the projector is via cannon 3 pin XLR plugs and sockets which are included with the projector. The
XLR's are connected as shown in the figure above.
Note, care should be taken to ensure that none of the connections touch the body of the plug or each
other. The body of the plug is not connected in any way. The MANTIS accepts digital control signals in
standard DMX512 (1990) format.
5/12
Mantis manual.doc
5-PIN AND 3-PIN CONVERSION
MANTIS uses 3-pin XLR plug / socket. If your controller uses 5-pin XLR plug / socket, you should
convert 5-pin plug / socket into 3-pin socket / plug as shown below.
DMX TERMINATOR
In the Controller mode or Master/Slave mode, the DMX output has to be connected with a DMX
terminator at the last fixture in the chain. This prevents electrical noise from disturbing and corrupting
the DMX control signals.
The DMX terminator is simply an XLR connector with a 120Ω (ohm) resistor connected across pins 2
and 3, which is then plugged into the output socket on the last projector in the chain. The connections
are illustrated below.
Without connecting a controller with the projector, the projector will run in Stand-Alone mode controlled
by sound or auto programmes via setting the DIP switch as shown below.
While sound controlling, the projector will change the colours/gobos according to the rhythm of the
music.
STAND-ALONE MODE
6/12
Mantis manual.doc
MASTER / SLAVE SYNCHRO MODE
Without using the controller, many projectors can
run synchronously by linking them with each other
in the Master/Slave mode.
Select one projector as the master without
connecting any cable to the projector’s input, and
set DIP switches as shown on the right.
Regard the other projectors as the slaves, and set
the DIP switches as shown on the right.
Connect the master’s output to the first slave’s
input, and connect the first slave’s output to the
second slave’s input. The rest may be deduced by
analogy. Eventually connect the last slave’s output
to a DMX terminator as shown in the figure above.
In the Master/Slave mode, all slaves will change
colours and gobos synchronously according to the
master.
CONTROLLER MODE - DMX OPERATION
CONNECTING THE CONTROLLER WITH THE UNITS
Connect the controller’s output to the first projector’s input, and connect the first projector’s output to
the second projector’s input. The rest may be deduced by analogy. Eventually connect the last
fixture’s output to a DMX terminator as shown in the figure below.
The red LED indicator blinking means the projector is receiving DMX 512 signal normally.

TABLE FOR SETTING ADDRESS OF DIP SWITCHES
The following table lists the setting codes of the address of the DIP switches, and the luminaires are
from No.1 to No. 85. Each DIP switch has 10 switches with the number of #1, #2, #3, #4, #5, #6, #7,
#8, #9 and #10.
In the table, “0” means the switch is on the “OFF”, and “1” on the “ON”.
For example, if you want to look up the address setting of the No. 10 luminaire, you will find the No.
10 luminaire row (#1, #2, #3, #4) with the codes of “0”, “0”, “1”, “1” and column (#5, #6, #7, #8) with the
codes of “1”, “0”, “0” , “0”. So set the #3, #4 and #5 switches on the “ON”, and set the #1, #2, #6, #7,
#8, #9 and #10 switches on the “OFF”.

If the projector’s lens becomes damaged or broken it should be replaced. If the lamp becomes
damaged or deformed in any way it must be replaced. If the light from the lamp appears dim this would
normally indicate that it is reaching the end of its life and it should be changed at once, old lamps run
to the extremity of their life can explode. If the projector does not function, check the fuses on the
power socket of the projector, they should only be replaced by fuses of the same specified value
4A/250V (fast blow, 5mmx20). Should these be damaged call a qualified technician before
replacement. The projector has thermal protection device that will switch off the projector in case of
overheating, should either of these operate, check that the fans are not blocked, and if they are dirty
clean them before switching on the projector again. Check that the fans are operational, if not call a
qualified technician.
Any maintenance work should only be carried out by qualified technicians.
To ensure the reliability of the projector it should be kept clean. It is recommended that the fans should
be cleaned every 15 days. The lens and dichroic colour filters should also be regularly cleaned to
maintain an optimum light output. Do NOT use any type of solvent on dichroic colour filters.
Cleaning frequency depends on the environment in which the fixture operates: damp, smoke or
particularly dirty surroundings can cause greater accumulation of dirt on the unit’s optics. A soft cloth
and typical glass cleaning products should be used in cleaning. It is recommended to clean the
external optics at least once every 20 days and clean the internal optics at least once every 30 / 60
days.
KEEPING THE PROJECTOR CLEAN
Do not use any organic solvent, e.g. alcohol, to clean the housing of the projector.
