JBL G732 Manual

							Now there’s a full line of speakers d 
and systems that bring JBL’s legendary 
concert sound to every club and hall 
you play. Our new Performance Series 
incorporates many of the same preci- 
sion features found in our industry- 
hailed tour sound systems. No other 
speaker systems in its class can touch 
the Performance Series’ power han- 
dling, ruggedness and sound character. 
QUEST 
FOR THE 
PERFECT STAGE SPEAKERS 
At the heart of every Performance 
Series system you’ll find our thoroughly 
researched G Series loudspeakers. The 
G125-8 (12 inch) and G135A-8 (15 inch) 
are the result of nearly two years of 
intensive acoustical and physical 
testing. 
The research began in 1984 when 
JBL’s Artist Advisory Board (under the 
lea&&in nf ~mnlifier 
I .,,‘,)a “L UnLlpnn” 
rd Paul Rivera; 
launched an exhaustive 
study of the entire 
instrument speaker 
market. They took a 
careful look at every- 
The G 125-8 300~11 competitive product 
( 12 inch) loudspeuher and discovered that 
todays pro players 
often needed two speakers onstage: 
one for smooth distortion, another for 
clean sound. 
Rivera’s team noted that speakers 
used primarily for distortion offered 
far less power handling and efficiency 
than their “clean” sounding counter- 
parts. Ironically, the clean speakers 
were too revealing for many rock 
guitarists, failing to cover up things like 
high-frequency hiss and fret buzzes.  
						

							L To remedy this situation, JBL 
launched its G Series in 1986. Both the 
Gl25-8 and G135A-8 offer full-bodied 
sound without top-end 
noise. And both have 
far greater power 
handling and ef- 
ficiency than those 
speakers prized 
solely for distortion 
capabilities. The 
G Series is the first 
The Gl35A-8 380 mm line of speakers 
( 15 incCI) 
loudspeaker. that truly lets per- 
forming musicians 
have their cake and eat it, too: both 
raw and clean sound.. able to rock 
louder, longer and with more detail 
than any other stage speakers 
in 
their class. 
L 
The G Series speakers were such an 
immediate hit with musicians that JBL 
began incorporating them in portable 
Vocal Reinforcement, Stage Monitor, 
and Keyboard Reinforcement sys- 
tems-a full line of products we now 
call our Performance Series. Each sys- 
tem delivers the classic, multi-purpose 
G Series sound in enclosures designed 
to be exceptionally durable, light- 
weight. and easy to transport.

PROFESSIONAL APPEARANCE AND EASY PORTABILITY 
JBL believes that it’s not enough to 
be the finest sounding stage speakers 
on the market. We’ve also paid close 
attention to the Performance Series’ 
appearance and portability. 
Each enclosure is designed to 
enhance your professional image. 
Interlocking corners make stacking 
easy and reduce onstage clutter. And 
the specially designed corner protec- 
tors have the distinctive JBL logo 
tooled right in. (The C-730, G-733, and 
C-734 can also be mounted on JBL’s 
Model MT-4612 aluminum tripod 
stand.) Musicians who are tired of lugging 
back-breaking speaker systems will 
appreciate the Performance Series’ 
lightweight construction. Most club 
speakers are made from heavy-yet- 
fragile particle board. Ours are built 
from high-quality void-free plywood 
(multi-laminate cross-grain hardwood) 
for the optimum combination of light 
weight and ruggedness. 
To prevent damage during transport, 
all Performance Series products have 
easy-to-grasp, recessed handles and 
the speaker front is fully covered by a 
protective steel grille.
