The CAL steerable column array loudspeaker
combines over three decades of technological
innovation and advanced research into the laws
of physics and digital signal processing to achieve
unprecedented accuracy in sound reproduction.
Designed primarily for vocal reproduction in
fixed installations, the self-powered CAL offers
variable vertical beam coverage (as narrow as
5 degrees and as wide as 30 degrees) that can be
digitally steered up or down by 30 degrees. CAL’s
beam steering takes the practice of directing
sound to the next level, and with a smart, lean
profile, CAL sets the standard for high-quality
sound installations.
CAL is available in three models, each providing
a different output level — up to a maximum peak
SPL of 106 dB at 90 meters with CAL 96 — over an
operating frequency range of 100 Hz to 16 kHz.
Providing a horizontal coverage of 120 degrees,
as well as the flexibility of vertical beam steering,
a single unobtrusive CAL delivers clear vocal
reproduction over a large area while minimizing
undesirable reflections.
Discrete onboard Class D amplifier channels,
processed by sophisticated algorithms, power
each driver and tweeter. The amplitude and
phase responses of each driver are engineered
to produce interactions that yield the desired
vertical coverage. Controlling each element
individually yields greater flexibility and precision
than other beam steering systems that control
modules comprised of multiple drivers.
The accuracy of CAL’s vertical steering allows
system designers to pinpoint coverage, even
when mounting options in a venue do not allow
for physically aiming a loudspeaker toward
a coverage area. CAL 96 and CAL 64 include
split beams that can be configured to fit the
application, for example, to avoid hitting a
reflective balcony surface. To meet the high
intelligibility requirement for vocal reproduction,
CAL has been engineered to maintain accurate
beam steering up to 10 kHz, well beyond the
benchmark of 4 kHz used in traditional single-
driver loudspeakers.
CAL™ : Column Array Loudspeaker
DATASHEET
CAL loudspeakers include two AVB-enabled
Ethernet ports for receiving AVB audio streams as
source signals. The ports also provide computer
control of CAL via Meyer Sound’s Compass
control software, allowing beam control and
RMS™ real-time monitoring of each loudspeaker
on the network.
