Meyer Sound PARABOLIC SOUND BEAM SB-1 - Manual

SB-1
Why did Meyer create the SB-1?
The SB-1 is intended to solve one of the most common problems in
large-scale reinforcement: assuring effective high-frequency reproduction
at great distances from the main PA.
Traditional solutions for long-range high-frequency projection have
employed narrow-coverage horns (also called “long throw” horns). But
the sound pressure produced from a horn decreases by 6 dB with each
doubling of distance from the source, and this substantially limits its
useful range. Certain methods for stacking or arraying horns can
increase the system’s throw by effectively moving the acoustical source
farther behind the array, but these techniques break down at
propagation distances greater than about 100 feet.
The SB-1 Sound Beam is the first practical alternative to horns for
large-scale long-throw applications. It produces sound waves whose SPL
decreases by as little as 3 dB per doubling of distance, with flat
response and consistent bandwidth over five octaves — and its pattern
remains consistent for distances up to 500 feet.
What Meyer systems is it designed to work with?
The SB-1 can be used to supplement any large-scale long-throw main PA
system, including those comprised of MSL-3s, MSL-4s, MSL-5s, MSL-6s,
or MSL-10s in any combination.

Q&A
The Meyer Sound SB-1
Parabolic Sound Beam is
a powerful, long-throw
device for projecting
mid- and high-frequency
energy over distances
from 100 to 500 feet.
By producing an
extremely narrow, tightly
controlled beam of sound
energy, the SB-1 enables
very effective long-range
“fill” coverage in large-
scale sound reinforcement
applications.
The SB-1 comprises an
optimized aspherical
waveguide with 2-inch
throat (4-inch
diaphragm diameter)
compression driver
feeding a large parabolic
reflector, and a 12-inch
cone driver mounted at
the center of the reflector.
Built-in electronics
include dual
complementary
MOSFET class AB/H
amplifiers with 1240
watts total power output,
TruePower™ Limiting
driver protection, and
frequency and phase
response alignment
circuitry. This powerful
combination of
components provides flat
response from 500 Hz to
15 kHz and 110 dB
peak SPL output at
100 meters.
