Using a range of vertical control presets programmed for the steerable column array loudspeakers, system integrators can choose the angle and dispersion to accurately project sound where needed while avoiding surfaces that interfere with speech signal transmissions. For acoustically challenging spaces such as churches, mosques, airports, cruise ships, stadiums, and theme parks, intelligible voice reproduction and smooth audio coverage can now be achieved with fewer, strategically placed loudspeakers, effectively preserving a venue's aesthetic integrity, says the company.
The high-fidelity CAL steerable column array loudspeakers incorporate powerful digital signal processing as found in the Meyer Sound D-Mitri digital audio platform, and are built upon sound directivity research in collaboration with the University of California Berkeley's Centre for New Music and Audio Technologies (CNMAT).
Designed by Meyer Sound engineers to be used for sound field synthesis applications and optimised for beam steering, each driver and tweeter is powered by a dedicated amplifier channel to accurately control the vertical behaviour. CAL provides 120 degrees of horizontal coverage and is available in three versions of column lengths ranging from less than one metmr up to 1.8m to meet an installation's power and coverage requirements, operating across a frequency range of 150 Hz to 10 kHz.
CAL supports AES/EBU digital and AVB-enabled Ethernet inputs in addition to line level analogue inputs, and is equipped with the RMS remote monitoring system. Available options include weather protection and custom colour finishes.
