CHAPTER 6: QUICKFLY RIGGING

POLE-MOUNTING THE UPJUNIOR

You can mount a single UPJunior on a pole with a third-party

pole-mount adapter (such as the BMB-200K mounting

bracket from Ultimate Support).

THE MUB-UPJUNIOR U-BRACKET

You can use the MUB-UPJunior U-bracket to mount a single

UPJunior on walls, ceilings, and stage lips, to mount up to

two UPJuniors on a tripod, or to mount an array of UPJun-

iors. The U-bracket’s adjustment slot lets you adjust how

close the UPJunior is located to the mounting surface and at

what angle the loudspeaker will be positioned. The MUB-

UPJunior U-bracket kit includes two M8, 16 mm bolts.

NOTE: When mounting a single UPJunior with

the MUB-UPJunior U-bracket, the bracket

should be fastened to the center holes on the loud-

speaker’s top and bottom plates. When flying an

array of UPJuniors from the MUB-UPJunior U-

bracket, the bracket should be fastened to the holes

toward the rear of the loudspeaker plates to compen-

sate for the shift in center of gravity.

MUB-UPJunior U-Bracket Load Ratings for Flown

UPJuniors

An array of up to three UPJuniors can be flown with the

MUB-UPJunior U-bracket at a 7:1 safety factor. When flying

any number of UPJuniors with the MUB-UPJunior U-

bracket, the U-bracket must be secured to the mounting

surface with either the two 1/2” center holes or the four 1/4”

corner holes.
