ll8L Filter Cards ofter an extensive
menu of pre-set features as weil as
user selectable functions, setting
new standards for system adapt­
bility with limiters which can be
adjusted to match amplifier gain
and with connections for sub­
woofers in vented enclosures or
Tripie Chamber Bandpass (TCB)
enclosures.
The Sound Power Controller
has been designed specifically to
control sound, not to process it.
The Sound Power Series trans­
ducers do not need processing,
which would unavoidably impose
its own colorations and sonic
artifacts on the sound. The Sound
Power Series is dedicated to the
faithful reproduction of the original
signal .
Unlike typical heavy-handed
limiters which cut oft musical
transients vital to the liveness of
he JBL Sound Power
Systems approach pro­
vides the user with a
wide selection of high quality
total sound system solutions to
fulfil virtually any need in SR, PA
and MI applications.
Each Sound Power System
consists of a perfectly matched
combination of selected Sound
Fbwer loudspeakers and MPA
power amplifier components totally
integrated by the Sound Power
Controller configured with pre-set
system-specific dedicated filter
cards.
The Sound Power systems
solution removes the guesswork in
selecting speakers, crossovers,
power amplifiers and, equally
important, in the combining of
these components into perfectly
matched systems with optimum
performance. The Sound Power

testing, removing virtually every
conceivable source of user error.
User access is restricted to non­
critical parts and functions, elimi­
nating a major source of potential
error and damage.
Because power line voltage in
the field can vary wildly, the JBL
Sound Power Controller is de­
signed with a switching power
supply which can handle extreme
swings from an unstable voltage
supply and will function with a line
voltage from 100-240 volt.
To assist the user in optimizing
the application of a chosen system,
JBL ofters the CADPZM and SRDSTIVi
computer software programs. Based
on the physical details of the venue
and the proposed Sound Power
System configuration, SRDSTfv1 ofters
a quick estimate of basic perfor­
mance parameters, while CADP2™

Controller has been integrally
designed with the Sound Power
Series speakers to create total
system solutions where extensive
pre-set functions expedite initial
set-up procedures. At the same
time, the Controller will allow the
user all the flexibility required to
adapt the system to any specific
situation.
The Controller consists of a
main unit plus a dedicated pre-set
system filter card configured to
match the specified Sound Power
System of your choice. The JBL
Sound Power Controller System

Sound Power Controller preserve
the integrity of the original signal,
based on true RMS detection,
operating as a "gain control';
predicting the heat generated in
the speaker. The JBL Sound Power
Controller protects the speaker
from overheating, while leaving
intact the crucial musical transi­
ents which JBL transducers
handle with the greatest of ease.
The ergonomics and operation
of the JBL Sound Power Controller
have been refined during endless
hours of hands-on, real world field

The bottom line: The Sound
Power Systems approach makes
life easier for the user by removing

selection of sound systems. With
JBL's dedicated software, the
performance of a given system can

TOURING arge scale sound rein­
forcemellt is a highly
specialised field involving
the consistent and reliable
delivery of tremendous sound
pressure levels into huge and often
irregular spaces. Serious
professionals demand serious
professional systems that can
perform consistently under
extreme conditions.
The JBL Sound Power Touring
Series offers a simple and efficient
solution to the complex problems
of PA for major events with a new
horn/compression driver combina­
tion, more efficient powerful
woofers and cutting edge JBL
driver technology including flat wire
coils, Symmetrical Field Geometry
(SFG™), Vented Gap Cooling
(VGCM), titanium diaphragm
compression drivers and Bi­
Radial™ horns.
The resulting drivers demall­
ded similar breakthroughs in cross­
over technology and enclosure
build, enabling the JBL Sound
Power Touring Series to reach new
levels of musical performance
efficiency, compactness and
reliability.
L
STRUCTURAllNTEGRITY
The superior strength and rigidity
of the JBL Sound Power Touring
cabinets are achieved using high­
density 21 mm 13-ply Finnish
birch hardwood construction and
comprehensive internal bracing.
The cabinets are attractively
finished in a durable black acid­
hardened paint that resists scuffing
and chipping during transport,
set-up and rigging.
Every JBL Sound Power
Touring loudspeaker sports a
3
removable grille of 2 mm per­
forated steel lined witll open cell
reticulated foam to protect against
moisture damage and dust.
RIGGING
The integrated aluminum corner­
mounted hanging system protects
cabinets during transport, while
providing unique flexibility and
strength during installation.
The integral mounting hard­
ware made from a special an­
nealed aluminum alloy surpasses
the strictest safety standards. The
mounting system allows convenient
stacking or clustering and the
enclosurelbrace combination can
handle in excess of 10 tons. You'lI
bring the roof down, long before
these reliable braces give way.
In clusters the integral hanging
points create a "unified front;' effec­
tivelya single, continuous baffle
with no gaps between the cabi­
nets, enhancing overall system
performance.
ACCESSORIES
The comprehensive range of JB L
electronics, accessories and
cabling options enhances the total
system flexibility that has been a
primary design goal for the JBL
Sound Power Touring Series.
For signal interface JBL
employs specialised Neutrik
connectors, long championed by
JBL for their long-term reliability,
improved current characteristics
and absolutely air-tight sockets.
