The HDA has three features on the bottom side of
each cabinet:
11 & 12. DUAL-ANGLE POLE CUP
The rear pole cup [11] is for use with a single unit on
a pole. It orients the HDA for output parallel to the fl oor.
The front pole cup [12] serves two purposes. It angles
the HDA downward 20˚ to aim at the audience below
the loudspeaker. It may also be utilized for use with
two HDAs arrayed on one pole as seen in the hook-up
diagram on page 8.
13. COMPRESSION PAD
The compression pad supports the weight of multiple
units in a fl own array. It helps protect the wood cabinet
from damage.
14. RUBBER RUNNERS
The rubber runners provide traction when the HDA is
used as a front or side fi ll. They are also used as mating
grooves when arraying multiple HDAs.
