horn provides a much wider

narrower vertical beam width
(100°H x 40°V) than the UPA-2P.
Both speakers share the
following remarkable attributes:
• uniform frequency response
within the beam width
• rapid and uniform amplitude
attenuation for all frequen-
cies outside the beam width
• minimal side lobes

shipped with one of two audio
input and control options. The
Basic module contains an XLR
input and a loop connector.
The second module provides
features that facilitate array

full-range systems without
incurring the cost of external
processors. These inter-
