1. Product overview
The Chroma-Q Universal is designed to give years of trouble free use, providing that it is regularly maintained & is used in
accordance with the instructions detailed in this manual. If you should experience any problems that fall outside of the scope
of this manual, please contact the selling dealer.
The Chroma-Q Universal is a scrolling colour changer designed to operate on the ANSI E1.11 USITT DMX 512-A protocol.
This multiplexed serial data system allows for the individual addressing of multiple units on one data cabling system. The unit
utilises one or two DMX channels depending on the mode of operation.
The unit is addressed by using the three push button switches & LED display on the rear panel. These switches are also used
to select mode of operation, scrolling speed & cooling fan speed.
The Chroma-Q Universal is supplied power & control signals by means of two 4-pin XLR style connectors on the rear panel,
allowing multiple units to be 'daisy-chained' into the same line of cabling. Patching the output from the last unit back into the
power supply will terminate the DMX for each chain line & ensure even power voltage across all scrollers in that chain.
Note: The quantity of Chroma-Q Universal colour changers, & maximum cable length per power supply output is dependant
upon the size of PSU/splitterbox used (see later in this manual for details).
The rear of the unit incorporates an integral universal mounting bracket, which allows the unit to be easily configured to fit on
fixtures from 160-275mm / 6¼"-10¾" frame size.
The Chroma-Q Universal is equipped with two internal cooling fans & a diagnostic section on the LED display showing power,
DMX signal & level presence.

2.1 Control and power cables
The Chroma-Q Universal utilises an XLR 4-pin cable system. This is used for power & data transfer. Pins 2 & 3 are for ANSI
E1.11 USITT DMX 512-A data. Pins 1 & 4 are for 24VDC power.
Damage will occur if power connections short to data or ground/shield connections.
When assembling XLR 4-pin cables, heat shrink should be used on each individual pin to prevent short circuits (see diagram
below).
Note: It is very important to ensure that the drain wire from the cable shield is connected to both XLR connector cases.
