The SLS MA480AS is a high-power two-way loudspeaker, providing pan, tilt, and rotation capabilities for larger cinemas and auditoriums.
The SLS MA480AS is a high-power two-way loudspeaker, providing pan, tilt, and rotation capabilities for larger cinemas and auditoriums. The SLS MA480AS provides an 80° vertical x 80° – 130° asymmetrical horizontal dispersion pattern for more uniform coverage in all seating locations across the auditorium or theatre.
Featuring a 400 W, 12” coaxial full-range speaker and passive crossover, the MA480AS is housed in a spherical-shaped molded enclosure that enables quick installation and easy three-axis aiming for fulfilling Dolby Atmos® aiming requirements.
The MA480AS was designed primarily for Dolby Atmos® top surround applications but can also be used for side surrounds in some cases. The MA460AS is also available if a 60°V x 60° – 150°H asymmetric dispersion pattern is desired.
