Overview

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-noise4) 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.
