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.

3.2 Nexus X overview
The 8000 Watt Nexus X serves the lower spectrum of the Nexus LF system. It does this with
unmatched displacement via its eight 12” transducers, each capable of extreme amounts of
excursion with very low distortion.
Eciency is also o the chart thanks to the vast number of transducers all working in
unison in an optimally designed yet deceptively compact enclosure which uses the latest in
material technology to assist in minimising resonances. Dual Neutrik speakONTM NL4s are
provided for driver connections.

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.
