The CAL steerable column array loudspeaker incorporates over
three decades of technological innovation and advanced research
to achieve unprecedented accuracy in sound reproduction. The
first loudspeaker to be certified for AVB interoperability by the
Avnu Alliance®, the self-powered CAL is designed primarily
for vocal reproduction in fixed installations. It offers variable
vertical beam spread (as narrow as 5° and as wide as 30° in 5°
increments) that can be digitally steered up or down by 30° (in
1° increments). 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 linear peak SPL of 101 dB with 18.5 dB
crest factor (measured using M-noise

4

) for CAL 96 at 90 m—over
an operating frequency range of 100Hz to 16kHz. Providing a
horizontal coverage of 120°, 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 response of each driver are engineered
to produce interactions that yield the desired vertical spread.

Controlling each element individually yields greater flexibility
and precision than other beam steering systems that control
modules consisting 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 maintains accurate
beam steering up to 10 kHz, well beyond the benchmark of
4kHz used in traditional single-driver loudspeakers.

CAL loudspeakers include AVB-enabled Ethernet ports that
accept AVB audio streams as source signals, and also provide
computer control of CAL via Meyer Sound’s Compass control
software which allows beam control and RMS™ real-time
monitoring of each loudspeaker on the network.

CAL comes standard with adjustable mounting brackets for
installation on walls or columns. The low-profile aluminum
enclosure is available in white, black, and custom colors, allowing
it to blend easily into any background. Weather protection
permits outdoor installations in most environments.
