Ceiling Mounting a Vertical Array
In the vertical array configuration (Figure 7.13), the top
cabinet is mounted to the ceiling using the MLB-UPJ L-
bracket.

and the MLB-UPJ
Flying a Vertical Array
Eyebolts can be also attached to the MAA-UPJ to provide
pick-up holes for flying a vertical array. In addition, the
MAA-UPJ’s rear pick-up holes can be used for additional
support or better control over vertical coverage of the array
(Figure 7.14).

eyebolts in the top cabinet
TIP: To create optimum coverage in a
vertical array the splay between UPJ-1P
speakers should be 30° when the horns are in the
80° horizontal by 50° vertical position. Angles of
less than 30° between cabinets can create too
much interaction between loudspeakers and angles
greater than 30° can create holes in the coverage.
For example, a vertical array of three UPJ-1Ps
splayed 30° will have a optimal horizontal coverage
of 80° horizontal by 100° vertical.
