DEPLOYING THE SYSTEM
The VRX932LA is a flexible speaker system that can be deployed in ground-supported or suspended applica-
tions. The following information will help you set up your VRX932LA system safely and effectively.
POLE AND TRIPOD SAFETY WARNINGS!
When using stands or poles, be sure to observe the following precautions:
• Check the stand or pole specification to be certain the device is designed to support the weight of the
speaker. Observe all safety precautions specified by the manufacturer.
• Be certain that the surface on which the system is to be stacked is flat, stable and solid.
• Route cables so that performers, production crew, and audience will not trip and topple the speakers.
• Inspect the stand (or pole and associated hardware) before each use and do not use equipment with
worn, damaged, or missing parts.
• Do not attempt to place more than two VRX932LA loudspeakers on a stand or pole.
• When mounting two VRX932LA speakers on a pole or tripod, integral rigging hardware must be used to
secure the speakers to each other.
• Always be cautious when deploying the system outdoors. Unexpected winds may topple a system. It may
be necessary to place additional weight (i.e. sandbags) on the base of the stand to improve stability. Avoid
attaching banners or similar items to any part of a speaker system. Such attachments could act as a sail
and topple the system.
• Unless you are confident that you can handle the weight of the speaker, ask another person to help you
get it onto the tripod stand or pole.
• One or two VRX932LA loudspeakers may be mounted onto either a JBL SS2-BK tripod stand or a JBL
SRX718S subwoofer with an SS4-BK adjustable pole. Do not stack more than two VRX932LA speakers
on a pole. When pole mounting on the SS4-BK, the pole is not to be extended beyond 1448 mm (57 in).
Single VRX932LA
A single VRX932LA may be used on a tripod stand (JBL SS2BK) or on a pole
over a subwoofer (JBL SS4BK and SRX718S). The use of a subwoofer is recom-
mended for applications requiring more low-frequency power and extension.
Usually, the Array Configuration Selector (ACS) switches on the input panel
should be set to the "Short Throw (-3 dB)" position when a single speaker is
used.
The VRX932LA includes a dual angle pole mount socket. By selecting the appro-
priate pole socket and adjusting the height of the tripod or pole, optimum cover-
age may be achieved. Ideally, the audience should not be able to see either the
bottom or the top surfaces of the speaker. This will insure that all listeners are
within the "included coverage angle" of the loudspeaker. The rear pole-socket will
position the speaker with the baffle 2.5º to the floor while the forward socket will
position the speaker with the baffle angled down by 15°. System illustration
