RIGGING & MOUNTING

Specifications for insert mating hardware

Group A should use an M6, grade 8.8 or better, 1.0 mm per thread, metric bolt, that does not penetrate the cabinet

past the cabinet surface more than 20 mm (approximately 3/4"). When using a Peavey Versamount 35 mounting

bracket and lockwasher, the length of the bolt should not exceed 30 mm (approximately 1.125").

Group B should use the supplied knob-head bolts, OR an M8, grade 8.8 or better, 1.25 mm per thread, metric bolt,

that does not penetrate the cabinet past the cabinet surface more than 20 mm (approximately 3/4").

Insert C should use an M8 forged steel shoulder-type lifting eyebolt, which meets the requirements of DIN 580 or

ASTM A489, or whatever local, provincial or national suspension ordinances or regulations may additionally

require. The depth of penetration of the threaded shank on the eyebolts should not exceed 20 mm (approximately

3/4"), so that it does not engage the interior of the cabinet's sound absorbing lining. Thread pitch: 1.25 mm per

thread.

Notes on specific mounting methods using optional accessories

Mounting Method 1 - U-Bracket

Use the large handled knob-headed bolts to mate the U-Bracket to the cabinet, placing lockwashers between the

bracket and bolt. See diagram above. Determine the angle that the cabinet needs to be relative to the U-Bracket,

and position the cabinet to that angle, and screw-in a small handle knob-headed bolt through the threaded

angle-set hole in the bracket into one of the 24 angle location holes on the cabinet. Use the hole nearest the angle

desired.

For permanent installation, the large handled knob-headed bolts can be substituted for with hex head bolts by

using the specifications above (Group B). It is then recommended that thread-locker be used, and that a steel

metric M8 washer be used to prevent pull-through of the hex head. Using hex head bolts with thread-locker will

remove the possibility for someone to attempt to unscrew the knob-headed bolts by hand to vandalize or

otherwise alter the cabinets mounting.

If using the U-Bracket with the cabinet pointing straight out (bracket rear parallel to the rear of the cabinet), then

use of the NL-4 twist-lock connection is best made before locking the angle into place and using thread-locker.

Offset the cabinet till the NL-4 jack clears the bracket, and plug it up, then rotate the cabinet into the final position,

etc.

Mounting Method 2 - Peavey Versamount 35

Instructions for use are included with the Peavey Versamount 35, and for permanent installation, once the angles

have been finalized, use thread-locker on the four mounting bolts with lockwashers. The bolts for this method are

Group A.

Mounting Method 3 - Pole Mount Adapter

This adapter allows use of the cabinet with a speaker stand (also referred to as a tripod stand) for temporary

portable use. It is designed for use with a standard 1 3/8" (35 mm) diameter stand pole. This adapter is only

provided for use with the stand pole that is aligned basically straight up, no tilt should be present, or this could

cause an unsafe situation.
