Safety and Regulations

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 sufficient 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 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 userdependent and Void Acoustics Research Ltd cannot guarantee complete safety whenever the system is rigged and operated.

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 Nexus X loudspeaker from its original packaging:

Nexus X 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 ensure you use a lint free product to protect the finish
When you have removed the Nexus X 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.

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 speak onto NL4s are provided for driver connections.

Cable and Wiring

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. VOID-UG10577-Nexus-X-Subwoofer-2

Appendix

Architectural specifications

The loudspeaker shall be an active manifold bandpass sub system consisting of eight high power 12” (300 mm), long excursion, low frequency (LF) transducers mounted in a square enclosure.

Each low frequency transducer shall be constructed on a cast aluminium frame, with a treated paper cone, 101.6 mm (4”) voice coil, wound with copper wires on a high quality voice coil former for high power handling and long-term reliability.

Performance specifications for a typical production unit shall be as follows: the usable bandwidth shall be 36 Hz to 100 Hz (±3 dB) and shall have a maximum SPL of 152 dB peak (146 dB continuous) measured at 1 m using IEC268-5 pink noise. Power handling shall be 2 x 4000 W AES at a rated impedance of 2 x 4 Ω. Pressure sensitivity shall be 108 dB measured at 1W/1m. The system shall be powered by its own dedicated power amplification module with DSP management. The wiring connection shall be via two Neutrik speakON™ NL4 (one for input and one for loop-out to another speaker), to allow for pre-wiring of the connector before installation.
