Selecting Loudspeaker Models, Modules and Beam Patterns

Choosing Beam Patterns

There are three beam pattern options for the Panaray® MSA12X. You can choose the beam type depending on

the location of the array and shape of the coverage area.

Basic Steer/Spread

is the most basic beam pattern. First, steer the axis of the

beam vertically, then spread the beam from that axis. Steering and Spreading

are independent from each other. If spreading is applied, the beam is spread

symmetrically from the steer axis. When the Steer angle = 0 and the Spread

angle = 0, the radiation pattern of the array is the same as that of a (passive) non-

steerable columnar array, such as the Panaray MA12EX loudspeaker. Steer/Spread

works for the vertical plane only; horizontal steering/spreading is not supported.

Vocal Range Smoothing Option

Basic Steer/Spread has an option called Vocal Range Smoothing. With this option enabled (ON), the tonal

balance inside of the coverage becomes more consistent, and the sidelobes from the beam are suppressed.

The beam shape also becomes smoother, specifically around the vocal range. The trade-off of using this

option is that you lose a few dB of headroom.
