LEDJ SPECTRA BANK 4, 6, 8 OPERATION
Operation
After you have connected the Spectra Banks to the mains, the 10mm LED bar/s
start chasing.
The LCD display lights up and you can then choose the desired mode via the
MODE button:
• Stand alone mode
• Auto mode
• DMX mode
• Master/slave mode
• Sound activation mode
Stand-alone mode
Chaser:
A chase is a sequence of different steps that will be called up one after another in a
continuous loop. You can select up to 14 different pre-programmed chases.
Selecting a chase:
Press the SET UP button. Select the desired chase (00-14) via the
UP or DOWN buttons.
Select the desired chase sequence via the UP and DOWN buttons. (Step time/SP
or strobe speed/FS).
FS = Flash speed from 00 – 100% SP = Step time from 00 – 100% time/minute.
Auto mode
- In auto mode the chases are called up automatically in a continuous loop.
-The desired speed of the loops can be selected via the
UP and DOWN buttons.
Master/Slave Mode:
- The master/slave operation enables several units to be synchronized to one
master unit.
- On the rear panel of the Spectra Bank you will find an XLR plug and an XLR socket
which can be used for connecting several units.
Daisy Chain Connection
1) Connect the (male) 3 pin connector side of the DMX cable to the output (female) 3 pin
connector of the first fixture
2) Connect the end of the cable coming from the first fixture which will have a (female) 3 pin
connector to the input connector of the next fixture consisting of a (male) 3 pin connector.
Proceed to connect from the output as stated above to the input of the following fixture
and so on.

LEDJ SPECTRA BANK 4, 6, 8 OPERATIONS (CONT)
Sound Activation Mode
When in sound mode adjust the level control to enable the built in microphone to trigger
the internal programs.
DMX mode
The control panel allows you to assign the DMX unit address, which is defined as
the first channel from which the Spectra Bank 4, 6 & 8 will respond to the controller.
Addressing
Press the SET UP button until the display shows DMX mode DMX address 001.
Set the desired address via the UP and DOWN buttons.
DMX Channel Assignment:
When used in 5 channel mode all spectra banks (4, 6, and 8) use the following:
CH1
CH2 CH3 CH4 CH5
0 – 255
DIMMER
0 – 255
STROBE
0 – 255
RED
0 – 255
GREEN
0 – 255
BLUE
DMX CHANNEL MODE SELECTION:
The Spectra Bank 8 way has 4 DMX modes, 5, 8, 14, and 26 channel
(See following page for diagram)
The Spectra Bank 6 way has 4 DMX modes, 5, 8, 11, and 20 channel
(See following page for diagram)
The Spectra Bank 4 way has 3 DMX modes, 5, 8, and 14 channel
In all the above modes channels 1 and 2 are always DIMMER and STROBE
respectively.

LEDJ SPECTRA BANK 4, 6, 8 DMX SET UP
DMX-512:
• DMX (Digital Multiplex) is a universal protocol used as a form of communication
between intelligent fixtures and controllers. A DMX controller sends DMX data
instructions form the controller to the fixture. DMX data is sent as serial data that
travels from fixture to fixture via the DATA “IN” and DATA “OUT” XLR terminals
located on all DMX fixtures (most controllers only have a data “out” terminal).
DMX Linking:
• DMX is a language allowing all makes and models of different manufactures to
be linked together and operate from a single controller, as long as all fixtures and
the controller are DMX compliant. To ensure proper DMX data transmission,
when using several DMX fixtures try to use the shortest cable path possible. The
order in which fixtures are connected in a DMX line does not influence the DMX
addressing. For example; a fixture assigned to a DMX address of 1 may be
placed anywhere in a DMX line, at the beginning, at the end, or anywhere in the
middle. When a fixture is assigned a DMX address of 1, the DMX controller
knows to send DATA assigned to address 1 to that unit, no matter where it is
located in the DMX chain.
Further DMX cables can be
purchased from all good sound and
lighting suppliers or Prolight dealers.
Please quote:
CABL10 – 2M
CABL11 – 5M
CABL12 – 10M
Also remember that DMX cable must be daisy chained and cannot be split.

Notice:
• Be sure to follow figures 2 & 3 when making your own cables. Do not connect
the cable’s shield conductor to the ground lug or allow the shield conductor to
come in contact with the XLR’s outer casing. Grounding the shield could cause a
short circuit and erratic behaviour.
Special Note: Line termination:
• When longer runs of cable are used, you may need to use a terminator on the
last unit to avoid erratic behaviour.
Termination reduces signal
transmission problems and
interference. It is always
advisable to connect a DMX
terminal, (resistance 120 Ohm
1/4W) between Pin 2 (DMX-) and
Pin 3 (DMX+) of the last fixture
Figure 4
Using a cable terminator (part number CABL90) will decrease the possibilities of
erratic behaviour.
5-Pin XLR DMX Connectors:
• Some manufactures use 5-pin XLR connectors for data transmission in place of
3-pin. 5-Pin XLR fixtures may be implemented in a 3-pin XLR DMX line. When
inserting standard 5-pin XLR connectors in to a 3-pin line a cable adaptor must be
used. The Chart below details the correct cable conversion.
3- Pin XLR to 5-PIN XLR Conversion

Negative (-) Pin 2 Pin 2
Positive (+) Pin 3 Pin 3
