ARRI EVENT Systems
High Speed Ballasts
ARRI EVENT Systems have set the
standard for exhibitions, car shows and
other events where daylight sources
are required. The EVENT System saves
set-up time and costs with improved cable
management. Special EVENT Arrisun
and ARRI X heads are supplied by a
19” 4U pack via a single multicore cable.
For more details please refer to the
EVENT Brochure.
Location Multifunction Ballasts
Location Multi-function Ballasts save space
on set and make plugging up discharge
heads almost as easy as tungsten. A rolling
rack can power up to 18 lampheads via
multi-core cables. Standard ARRI heads
from 200 W to 4 kW can be used.
Intelligent splitter boxes are available in
two types: the 2/6/12 can supply 6 x 200
or 575 W heads or up to 3 x 1.2 kW heads
driven by pairs of channels while the
2.5/4 splitter operates up to three 2.5 or
4 kW heads.
The boxes identify the combination
connected so the appropriate power is
supplied without risk.
Boost Ballasts
High speed filming can demand very high
light levels for a short time. HMI is ideal
for this, producing 3-4 times as much
visible light as tungsten but with less
heat. Boost Ballasts over-drive standard
4 kW lampheads to 8 kW giving the highest
possible light output for high-speed
photography with smaller and lower cost
lampheads.
Both 19” rack mounted and stand-alone
versions are available with a range of
remote control options.
The advent of a new generation of highspeed
video cameras has created new
lighting challenges. High speed video,
previously the preserve of specialist
industrial film-makers has now become
mainstream. ARRI is pleased to introduce
a new generation of 1000 Hz High Speed
Ballasts that meet the challenge of
modern digital high-speed photography
with ease.
From experience gained making High
Speed 300 Hz ballasts for the industrial
market and developed in co-operation
with Weisscam, this new technology
offers worry-free shooting with standards
of exposure and colour stability suitable
for commercials and sport. 1000 Hz
ballasts are available for lampheads up to
4 kW and 300 Hz ballasts up to 18 kW.
Battery Ballasts
For ultimate portability, lampheads up
to 400 W can be battery powered from
24-36 V battery supplies via Electronic
Battery Ballasts. Ballasts can be powered
from standard battery technologies
including Lead Acid, NiCd, NiMH
and Lithium. Battery Ballasts have
lightweight extruded aluminium housings
for maximum portability allowing for
applications such as belt-pack use.
Lightweight Ballasts
ARRI equipment is known for the high
robustness demanded for film location
work, but for run-and-gun applications
lightweight ballasts up to 575 W are
available with lightweight extruded
aluminium housings, an ideal match
for the ARRI Pocket PAR lampheads.
Choke Ballasts
Accessories
Where flicker-free lighting is not required,
ARRI choke ballasts offer a robust, lowcost
solution. Choke ballasts are optionally
available with DMX remote control, ideal
for theatre and event applications.
To complement the range of ARRI
ballasts, available accessories include
head-to-ballast cable testers and a newly
redesigned Flicker Meter to check the
stability of any light source including HMI,
fluorescent, LED and display monitors.
The new model also includes frequency
and light intensity measurement.
