1.1 Important safety instructions
The lightning flash with an arrowhead symbol
within an equilateral triangle is intended to alert the
user to the presence of uninsulated “dangerous
voltage” within the product’s enclosure that may
be of sucient magnitude to constitute a risk of
electric shock to persons.
The exclamation point within an equilateral triangle
is intended to alert the user of the presence of
important operating and maintenance (servicing)
instructions in the literature accompanying the
appliance.
Safety instructions - read this first
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any ventilation openings. Install in accordance
with the manufacturer’s instructions.
8. Do not install near any heat source such as radiators, heat
registers, stoves, or other such apparatus that produce heat.
9. Do not defeat the safety purpose of the grounding-type
plug. A grounding type plug has two blades and a third
grounding prong. The third prong is 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 power cords from being walked on or pinched
particularly at plugs, convenience receptacles, and the point
where they exit the apparatus.
11. Onlyuseattachmentsandaccessoriesspecifiedby Void
Acoustics.
12. Only use 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the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 when the 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. Since the mains power supply cord attachment plug is used
to disconnect the device, the plug should always be easily
accessible.
16. Void loudspeakers can produce sound levels capable
of causing permanent hearing damage from prolonged
exposure. The higher the sound level, the less exposure
needed to cause such damage. Avoid prolonged exposure to
the high sound levels from the loudspeaker.
1.2 Limitations
This guide is provided to help familiarise the user with the
loudspeaker system and its accessories. It is not intended to provide
comprehensive electrical, fire, mechanical and noise training and is
not a substitute for industry-approved training. Nor does this guide
absolve the user of their obligation to comply with all relevant
safety legislation and codes of practice.
While every care has been taken in creating this guide, safety is
user-dependent and Void Acoustics Research Ltd cannot guarantee
complete safety whenever the system is rigged and operated.

7.1 Installation safety
To avoid mechanical hazards, please note the following:
• Safety regulations vary in dierent regions. Full compliance with those
regulations must be your priority
• Rigging must only be undertaken by fully-qualified and experienced riggers who
understand local regulations
• This may include consulting a structural engineer before installation of wall brackets
• Remember that all personnel have a duty of care to themselves, to their assistants, to the
venue sta and to the public
• Before lifting any part of the system above head height, check the whole rig for loose tools
or other items that may fall and cause injury
• Do not use a telephone (even if hands-free) while rigging. Always concentrate fully on the
rigging operation
• Do not rig equipment that is worn, damaged, corroded, mishandled or over-stressed in any way
• Use only Void-approved mounting equipment and accessories.
• Secondary safeties should be provided in all instances where cabinets are flying or fixing
overhead and should conform to local regulations
