DEPLOYING THE SYSTEM
The VRX932LA/VRX928LA are flexible speaker systems that can be deployed in ground-supported or
suspended applications. The following information will help you set up your VRX932LA/VRX928LA 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/VRX928LA loudspeakers on a stand or pole.
• When mounting two VRX932LA/VRX928LA 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 cabinets may be mounted onto either a JBL SS2-BK tripod stand or with the SS4-BK
adjustable pole mount to their companion VRX918S or SRX718S subwoofers. Do not mount VRX932LA
cabinets on top of the compact VRX915S subwoofer!
• One or two VRX928LA cabinets maybe mounted onto either a JBL SS2-BK tripod stand or their
companion subwoofer VRX915S. The larger type subwoofer SRX718S/ VRX918S
can also be used.
Single VRX932LA/VRX928LA
A single VRX932LA may be used on a tripod stand (JBL SS2-BK) or on a pole
(JBL SS4-BK) over its companion subwoofer the VRX918S or the SRX718S.
The use of a subwoofer is recommended 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.
A single VRX928LA may be used on a tripod stand (JBL SS2-BK) or on a pole
(JBL SS4-BK) over its compact companion subwoofer the VRX915S or the larger
VRX918S/SRX718S subwoofer models.
The VRX932LA/VRX928LA includes a dual angle 36 mm pole mount socket.
By selecting the appropriate pole socket and adjusting the height of the tripod or
pole, optimum coverage may be achieved. Ideally, the audience should not be able to
see either he 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 2.5° to the floor while the forward socket will
position the speaker with the baffle angled down by 15°. System illustration shows the
available JBL SS2-BK tripod stand.
*NOTE: VRX932LA-WH does not include pole mount features and is designed
specifically for fixed installations.
