CHAPTER 7
The UPJ-1P features Meyer Sound’s QuickFly rigging sys-
tem with rugged, reliable and deceptively simple compo-
nents. QuickFly facilitates placing UPJ-1P loudspeakers
from single units (hanging or attached to a surface) to con-
structing rigid, ground-stacked or own UPJ-1P arrays. The
UPJ-1P has integral top and bottom plates made of heavy
duty, high-strength, corrosion-resistant 6061-T6 aluminum
with threaded metric holes for use with QuickFly rigging and
third-party accessories.
NOTE: The threads of the MEP-UPJ end
plates are metric for M8 screws.
!
CAUTION: It is important to inspect rigging
hardware regularly and replace worn or dam-
aged components immediately.
!
CAUTION: All Meyer Sound products must
be used in accordance with local, state, fed-
eral and industry regulations. It is the owner’s and/or
user’s responsibility to evaluate the reliability of any
rigging method for their application. Rigging should
be carried out only by experienced professionals.
!
CAUTION: Always use properly rated rigging
hardware.

BASIC RIGGING CONFIGURATIONS

The UPJ-1P ships with two M8 threaded, 20 mm eyebolts
(including rubber washers), suitable for hanging the loud-
speaker using either a single- or two-hole conguration.
The single-hole conguration is the simplest way to support
one UPJ-1P cabinet (Figure 7.1).
Figure 7.1. Single-hole conguration
The two-hole conguration (Figure 7.2) is recommended
over the single point. This conguration provides more
safety, stability, and exibility for aiming and tilting the UPJ-
1P for targeted horizontal and vertical coverage.

!
CAUTION: Make sure that the eyebolts and
bolts are tightened securely. Meyer Sound
recommends using Loctite® on the eyebolt threads
and/or a safety cable.
!
CAUTION: Congurations using the
UPJ-1P’s eyebolt(s) do not support more
than two UPJ-1Ps at a 7:1 safety factor.
