1.1 Important safety instructions
The lightning flash with and 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.

5.1 Electrical safety
To avoid electrical hazards please note the following:
• Do not access the inside of any electrical equipment. Refer servicing to
Void-approved service agents.
5.2 Cable considerations for fixed installations
We recommend specifying installation-grade Low Smoke Zero Halogen (LSZH) cables for
permanent installations. The cables should use Oxygen Free Copper (OFC) of grade C11000
or above. Cables for permanent installations should be compliant with the following standards:
• IEC 60332.1 Fire retardancy of a single cable
• IEC 60332.3C Fire retardancy of bunched cables
• IEC 60754.1 Amount of Halogen Gas Emissions
• IEC 60754.2 Degree of acidity of released gases
• IEC 61034.2 Measurement of smoke density.
We suggest using the following maximum copper cable lengths to keep level losses below 0.6 dB.

6 Operating modes
6.1 Manual handling guidelines
To avoid manual handling hazards please note the following:
• Be sure to secure any loudspeaker systems following correct local
procedures/guideline
• Low frequency enclosures are heavy and require a minimum of two people to
move; for more information on safe handling consult INDG143.
6.2 Typical modes
Although the modes of arrangement shown here are typical operating modes for low
frequency enclosures, the Stasys 118 system’s symmetrical design lends itself to wide range of
configurations. Simple planer arrays and stacks to directional and steerable arrays are possible
given suitable electronics and presets. Contact your local Void distributor/dealer for more
information.
Single Horizontal
Vertical Block
Figure 6.1: Typical modes

Stasys 118 User Guide V1.0 Page 14
6.3 Cardioid modes
As low frequency enclosures are omnidirectional, rear projection can cause a range of
diculties. If there is a wall behind the array, the sound wave can reflect o the surface and
may cause cancellation in front if it arrives out of phase with the wave from the source.
Another problem may occur during performances where an array is deployed in front of
the stage, possibly creating a maximum sound pressure level that makes it dicult for some
performers. Adopting a cardioid configuration can overcome this problem as it creates a heart
shaped horizontal dissipation reducing the rear projection. A variety of cardioid configurations
are available, as shown below. For other layouts or more information, please contact your
local Void distributor/dealer.

Step 3:
Replace the M8 bolts by hand until finger tight
before using hand tools.
Note: Replacing bolts is of particular
importance as without them there
can be air leakage and detuning.
7 Adjustments
To avoid damage when making adjustments please note the following:
• Removing the grille can cause debris to collect within the enclosure, take care
to remove anything that may have collected internally
• Do not use impact tools.

8.2 Shipping and packing considerations
• When sending a Void Stasys 118 loudspeaker to an authorised service centre, please write a
detailed description of the fault and list any other equipment used in conjunction with the
faulty product.
• Accessories will not be required. Do not send the instruction manual, cables or any other
hardware unless your dealer asks you to.
• Pack your unit in the original factory packaging if possible. Include a note of the fault
description with the product. Do not send it separately.
• Ensure safe transportation of your unit to the authorised service centre.
