8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two
blades with one wider than the other. A grounding-type plug has two blades and a third grounding
prong. The wide blade or the third prong are provided for your safety. If the provided plug does not
fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched, particularly at plugs, convenience
receptacles, and the point where they exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer,
or sold with the apparatus. When a cart is used, use caution when moving the cart/
apparatus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has
been damaged in any way, such as power supply cord or plug is damaged, liquid has been spilled
or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does
not operate normally, or has been dropped.
15. WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.
16. Do not expose this equipment to dripping or splashing and ensure that no objects filled with liquids,
such as vases, are placed on the equipment.
17. To completely disconnect this apparatus from the AC Mains, disconnect the power supply cord plug
from the AC receptacle.
18. The mains plug of the power supply cord shall remain readily operable.

SECTION 2 : BEFORE YOU BEGIN
The VRX Series loudspeakers covered by this manual are not intended for fixed installation in outdoor or high
moisture environments. Moisture can damage the speaker cone and surround and cause corrosion of electrical
contacts and metal parts. Avoid exposing the speakers to direct moisture. Keep loudspeakers out of extended or
intense direct sunlight. The driver suspension will prematurely dry out and finished surfaces may be degraded by
long-term exposure to intense ultra-violet (UV) light.
The VRX Series loudspeakers can generate considerable energy. When placed on a slippery surface such as
polished wood or linoleum, the speaker may move due to its acoustical energy output. Precautions should be
taken to assure that the speaker does not fall off a stage or table on which it is placed.
Make sure the selected AC line voltage is correct.
STAND MOUNTING SAFETY PRECAUTIONS
Some VRX Series models can be used with an optional stand mount accessory allowing mounting on tripod
stands or on a pole over subwoofers. 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.
• Always verify that the stand (or subwoofer / pole) is placed on a flat, level, and stable surface and be
sure to fully extend the legs of tripod type stands. Position the stand so that the legs do not present a
trip hazard.
• Route cables so that performers, production crew, and audience will not trip over them and pull the
speaker over.
• 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 VRX932LAP Series loudspeaker on a stand or pole.
• Always be cautious in windy, outdoor conditions. 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.
HEARING DAMAGE, PROLONGED EXPOSURE TO EXCESSIVE SPL
VRX Series loudspeakers are easily capable of generating sound pressure levels (SPL) sufficient to cause
permanent hearing damage to performers, production crew and audience members. Caution should be taken to
avoid prolonged exposure to SPL in excess of 90 dB.
