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

Nexus Q overview
As part of the Nexus low frequency system, the Nexus Q delivers impressive upper bass frequencies via a new enclosure design. The four high power 12” drivers use a front-loaded horn to achieve high efficiency and a rear port with a newly developed pressure gradient arrangement. This configuration results in unparalleled output, definition, and total elimination of colouration from any turbulent or mechanical port noise.

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.

Amplifier loading guidelines

Ensure all amplifier channels are loaded equally. Limiters engage correctly. Cabinets’ acoustic principles are the same.

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.

Wheel removal

Step 1: Remove all four M6 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.
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

Grille removal

Step 1: Undo all twelve M6 tab bolts using a 4 mm Allen key, take care NOT to remove the tab bolts as they may become lost within the enclosure.
Step 2: Remove the grille.
Step 3: Replace the M6 bolts by hand until finger tight before using hand tools.

Service

Return authorization
Before returning your faulty product for repair, please remember to get a R.A.N. (Return Authorisation Number) from the Void dealer who supplied the system to you. Your dealer will handle the necessary paperwork and repair. Failure to go through this return authorisation procedure could delay the repair of your product. Note that your dealer will need to see a copy of your sales receipt as proof of purchase so please have this to hand when applying for return authorization.

Shipping and packing considerations

When sending a Void Nexus Q loudspeaker to an authorized service center, 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 authorized service center.

Appendix

Architectural specifications

The loudspeaker shall be an active manifold horn loaded subsystem consisting of four high power 12” (300 mm), long excursion, low frequency (LF) transducers mounted in a square enclosure with a rear port in a newly developed pressure gradient arrangement.

Each low-frequency transducer shall be constructed on a cast aluminum frame, with a treated paper cone, 101.6 (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 60 Hz to 150 Hz (±3 dB) and shall have a maximum SPL of 151 dB peak (145 dB continuous) measured at 1 m using IEC268-5 pink noise. Power handling shall be 2 x 2000 W AES at a rated impedance of 2 x 4 Ω. Pressure sensitivity shall be 110 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.

The enclosure shall be constructed from a 18 mm multi-laminate birch plywood finished in textured polyurea and shall contain fixture points for a pressed steel powder coated grille to protect the front chamber from object ingress. It shall have ten handles (four per side and two on the back face) for efficient manual handling – the same as external bracing from machined aluminium, which is bolted into the horn mouth using M8 stainless steel bolts.

The chamber of the loudspeaker shall incorporate a revolutionary, view through, shot gun port for better control over directivity and to reduce port noise at the same time as it also has cooling purposes, which shall be constructed from glass reinforced plastic in a trapezoidal shape with a smooth cellulose finish of any RAL colour. External dimensions of (H) 754 mm x (W) 738 mm x (D) 860 mm (29.7” x 29” x 33.9”). Weight shall be 130 kg (286.6 lbs).
