The HPI 111 can be flown in a permanent
installation by attaching the designed flying
hardware. The HPI111 can be wall mounted
or hung in a flown installation using the flying
fitting accessory. For more information, see
the Quest HPI flying hardware manual.
Before suspending any speaker system
always inspect all components (enclosure,
rigging frames, eyebolts, track fittings, etc.)
for cracks, deformations, corrosion, missing,
loose or damaged parts that could reduce
strength and safety of the array. Do not
suspend the speaker system until the correct
preparation of the installation site has been
taken to avoid health risks during and after
the completion of the installation. A licensed
Professional Engineer must approve the
placement and method of attachment to
the structure prior to the installation of any
overhead object.
Flying the HPI111
Rotating the Horn Flare
The asymmetrical horn flare can be rotated
through three separate planes of dispersion
depending on the speaker box requirement
and installation environment. The planes
are suited to either vertical or horizontal
installations.
Good coverage of audiences often requires
wide dispersion at the base of the horn flare
to cover close listeners and a focused narrow
dispersion at the top of the flare to beam to
the back of the room.
The HPI111 horizontal horn covers both
“short-throw” and “long-throw” requirements
in a single system. For the majority of
installations (where the box is installed
vertically), the asymmetrical horn should be
used as supplied and will not need to be
rotated.
For horizontal installation rotate 45 degrees
so the arrow is pointing at the floor side so
as to have the “beaming” facility at the top of
the horn.
WARNING
Ensure the box is securely located. If any doubt about the physical
stability, tie the box down with ratchet straps to a secure base.
