User Interface for Beam Shaping
Flat-Floor Optimized
Select
Flat Floor
from the beam type drop-down selector. This beam type is optimized for a flat-floor seating
arrangement. With this beam pattern, you can only steer the beam vertically, without any spreading. This
beam type can deliver consistent coverage from front to back specifically around the vocal range when the
array location (height) is appropriate, but if the array is located too high, you may not be able to achieve the
coverage you expect. Make sure the Bottom plate of the array is located 0.3 to 0.8 m (1 to 2.5 feet) above the
ear height of the audience.
Vocal Range Smoothing Option:
Select either ON or OFF. With this option ON, the tonal balance inside the
coverage becomes more consistent and the sidelobes from the beam are suppressed and the beam shape
becomes smoother, specifically around voice range. The trade-off of this option is that you lose a few dB of
headroom. By default, Vocal Range Smoothing is OFF with Basic Steer/Spread.
