Safety instructions – read this first

Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all instructions.
Do not use this apparatus near water.
Clean only with a dry cloth.
Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
Do not install near any heat source such as radiators, heat registers, stoves, or other such apparatus that produce heat.
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.
Protect power cords from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit the apparatus.
Only use attachments and accessories specified by Void Acoustics.
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.
Unplug the apparatus during lightning storms or when unused for long periods of time.
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.
Since the mains power supply cord attachment plug is used to disconnect the device, the plug should always be easily accessible.
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.

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.

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.
Efficiency is also off 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.

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.

---|---

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.

Metric mm2	Imperial AWG	4 Ù load	2 Ù load
2.50 mm2	13 AWG	18 m	9 m
4.00 mm2	11 AWG	30 m	15 m

Operating modes

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 four people to move; for more information on safe handling consult INDG143.

---|---

Typical modes

Although the modes of arrangement shown here are typical operating modes for low frequency enclosures, the Nexus X system’s symmetical 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.

Typical modes

Service

Void Nexus X loudspeakers should only be serviced by a fully-trained technician.

| No user serviceable parts inside. Refer servicing to your dealer.
