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.
1.3 EC declaration of conformity

www.voidacoustics.com/eu-declaration-loudspeakers
1.4 UKCA marking

Parliament on waste electrical finance the cost of treatment and
recovery of electronic equipment (WEEE) in order to reduce the
amount of WEEE that is being disposed of in land-fill sites. All of
our products are marked with the WEEE symbol; this indicates that
this product must NOT be disposed of with other waste. Instead
it is the user’s responsibility to dispose of their waste electrical
and electronic equipment by handing it over to an approved
reprocessor, or by returning it to Void Acoustics Research Ltd for
reprocessing. For more information about where you can send
your waste equipment for recycling, please contact Void Acoustics

2 Unpacking and Checking
All Void Acoustics products are carefully manufactured and thoroughly tested before being
despatched. Your dealer will ensure that your Void products are in pristine condition before
being forwarded to you but mistakes and accidents can happen.
Before signing for your delivery:
• Inspect your shipment for any signs of contamination, abuse or transit damage as soon
as you receive it
• Check your Void Acoustics delivery fully against your order
• If your shipment is incomplete or any of its contents are found to be damaged; inform
the shipping company and inform your dealer.
When you are removing your Stasys Xair loudspeaker from its original packaging:
• Stasys Xair loudspeakers come packaged in a lid and base carton that has a protective sleeve
around it; avoid using sharp implements to remove the cardboard to protect the finish
• If you need to place the loudspeaker on a flat surface make sure it is free from debris
• When you have removed the Stasys Xair loudspeaker from the packaging inspect it
to ensure there is no damage and keep all original packaging in case it needs to be
returned for any reason.
See section 1 for warranty conditions and see section 7 if your product needs servicing.

4 Cable and Wiring
4.1 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.
4.2 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.

Vertical BlockOn-end
5.1 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.
5.2 Typical modes
Although the modes of arrangement shown here are typical operating modes for low
frequency enclosures, the Stasys Xair 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.

6 Adjustments
Step 3:
Replace the M8 bolts by hand until finger
tight before using hand tools.
Note: Replacing bolts is of particu-
lar importance as without them
there can be air leakage and de-
tuning.
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.
6.1 Wheel removal
Figure 6.1: Bolt removal
Step 1:
Remove all four M8 bolts with a 13 mm
spanner/wrench.
Step 2:
Remove/add the wheels and keep in a safe
place. Repeat the process for the other three
wheels.
