The Meyer SB-1 parabolic sound beam is the first device to propagate
sound waves that decrease as little as 3 dB SPL per doubling of distance
for more than 300 feet, across a five-octave frequency range, with a
consistent and narrow beam width. Exploiting the well-known directional
behavior of a parabolic reflecting surface, the SB-1 provides the unprecedented
ability to precisely focus high-frequency fill energy over great distances
from a point-source system without the use of delayed fill loudspeakers.
The SB-1 comprises a fiberglass parabolic reflector dish with a bullet-shaped
pod containing a 4-inch compression driver and an aspherical horn, mounted
at the focus of the parabolic surface and aimed at the center of the
dish. A 12-inch band-limited cone driver is embedded inside the center
of the dish facing the pod to steer and focus the sound produced from
the horn. Mounted in a companion yoke, the dish housing serves as the
parabolic aiming mechanism and contains the amplification, signal processing,
and control electronics for both drivers. The high-frequency pod can
be disassembled and packed for shipping inside the dish.
The SB-1’s integrated electronics and amplifier system utilizes
the Intelligent AC power supply and the TruPower limiting system. The
Intelligent AC supply auto-selects the correct operating voltage (facilitating
international use), suppresses high voltage transients, provides soft-start
power-up (eliminating high inrush current), and sustains operation during
low-voltage periods. TPL protects the driver components from damage
due to overdriving and assures maximum peak output while minimizing
power compression. The SB-1 is RMS remote monitoring system compatible.
