MI-630
Vocal Reinforcement
System
Newly designed for vocal reinforce-
ment and general music reproduction
in small to moderate sized rooms. The
Model MI-630 and Ml-634 include integral
mounting hardware for use with the tubular
aluminum tripod stand, Model MT-4612.
MI-630 features the patented JBL flat-
front Bi-Radial' "
horn and compres-
sion driver mounted flush in the cabi-
net to eliminate the problems of
midrange narrowing and high fre-
quency beaming associated with
conventional
horn designs.
MI-631 Stage Monitor
Smooth, wide frequency
response
(60 Hz-l 5 kHz), uncolored reproduc-
tion, and high directivity
make this an
ideal stage monitor, acoustic instru-
ment system or even a small general
purpose vocal reinforcement
system.
The system uses the Ml Series 12 inch
loudspeaker
and flat front Bi-Radial' "
horn and compression
driver.
MI-632A Horn-Loaded
Sound
System
The MI-632A is a newly re-designed
system and features the new Ml-l 5A
380 mm (15" ) woofer with its copper
ribbon voice coil, giving the MI-632A
balanced bass with a smooth and con-
trolled sound. A three-position
HF
level control switch allows precise tai-
loring of the tonal balance between
horn and woofer.
Model Ml-634 Direct-Radiator
Sound System
The Ml-634 Direct-Radiator
Sound
System is a newly designed vented
enclosure system using the JBL Flat-
Front Bi-Radial' "
horn and compres-
sion driver and the new Ml-l 5A 380
mm (15" ) low frequency driver to pro-
vide smooth, uncolored response and
wide bandwidth with bass response
down to 50 Hz and high-frequency
response to 20 kHz. The smooth,
natural sound of the Ml-634 makes it
ideal for vocal and acoustical
instru-
ment reinforcement
and general
sound amplification
in small to mod-
erate sized rooms.
MI-291 High Frequency Power Pack
The MI-291 System offers the JBL
Flat-Front Bi-Radial' "
horn and
compression
driver as a separate add-
on system which allows simple instal-
lation to existing systems.
