Selecting Loudspeaker Models, Modules and Beam Patterns
Raked-Floor Optimized
As the name suggests,
Raked-Floor Optimized
is a beam pattern that is
optimized for raked floors. The Raked-Floor Optimized beam type achieves a
vertically-asymmetrical beam radiation, which is suitable for covering a raked
floor, or covering a flat floor from a relatively high array position, such as when
the bottom plate of the array is more than 1 m (3.3 feet) above the ear height
of the audience.
This pattern does not offer the Vocal Range Smoothing option.
Dual Beam Mode
Up to two beams can be radiated from an MSA12X array built from 1, 2 or 3 modules, with any beam pattern
selected independently for each beam. You can also apply individual gain and Room EQ* for each beam.
Note:
Dual Beam Mode is only available when using Dante® input.
Dual beams for the MSA12X is achieved by utilizing all the drivers of the array for both beams simultaneously.
By utilizing all the available drivers, better low-frequency directivity control for both beams can be achieved.
Other manufacturers may split their array into 2 smaller arrays (one on top of the other) to achieve dual
beams, but at the cost of performance.
