Installation
ColorBlast TRX fixtures are designed for easy setup, configuration, and teardown.
You can connect ColorBlast TRX fixtures directly to a power / data supply, such
as the PDS-750 TRX, using the built-in 6 ft (1.8 m) power cable with standard XLR
connector.
Owner / User Responsibilities
It is the responsibility of the contractor, installer, purchaser, owner, and user to
install, maintain, and operate ColorBlast TRX fixtures in such a manner as to comply
with all applicable codes, state and local laws, ordinances, and regulations. Consult
with the appropriate electrical inspector to ensure compliance.
Planning Your Installation
ColorBlast TRX is a highly flexible, capable LED lighting fixture with multiple points
of control. Your approach to addressing, configuring, and mounting ColorBlast TRX
fixtures will differ depending on your situation:
In simple installations using pre-programmed light shows available through the
▪
power / data supply, a lighting board, or DMX controller, it may not be necessary
to perform any onboard or per-fixture addressing and configuration. The
PDS-750 TRX, PDS-750 TR, and PDS-375 TR power / data supplies, designed
by City Theatrical, Inc., specifically for ColorBlast fixtures, offer push-button
configuration features that can automatically address all connected fixtures.
In rental, touring, and other temporary installations, it's often advantageous to
▪
address and configure fixtures in a prep area before hanging or mounting them.
Doing so requires you to power up the fixtures with a compatible power / data
supply, configure the fixtures with the onboard controls, and install any spread
lenses or other accessories. At the installation site, the fixtures must be hung or
mounted and reconnected to power.
In permanent installations, fixtures are likely to be installed in fixed locations
▪
and reconfigured for different purposes and events. In such situations, you can
configure ColorBlast TRX fixtures in position using the onboard controls, or you
can perform certain configurations over the lighting network using a personal
computer and QuickPlay Pro addressing and configuration software.
Because it's the most common situation, the following sections describe the process
for a rental or touring installation, where fixtures are addressed and configured in a
prep area, then hung at the installation site.
Create a Lighting Design Plan
and Layout Grid
1. Determine the appropriate location of each power / data supply in relation to the
light fixtures, and of the light fixtures in relation to each other.
ColorBlast TRX connects to the power / data supply over a built-in 6 ft (1.8 m)
power cable with a standard 4-pin XLR male connector. The power cable can be
extended with a standard XLR male to XLR female patch cable. The maximum
run length per power / data supply port depends on the wire gauges of the patch
cable:
Standard color scroller cables with two 14 AWG conductors for power and two
▪
22 AWG conductors for data are highly recommended. With these cables, you
can extend each fixture cable by up to an additional 175 ft (53.3 m).
Cables with 18 AWG conductors may also be used to extend each fixture cable
▪
by up to an additional 75 ft (22.9 m).
