Nexus 6 overview
Ideal for larger venues, the four-way Nexus 6 has an innovative internal transducer layout and 20 high power drivers, housed in a sculpted fibreglass enclosure. Virtual Arc technology forms a common acoustic centre at the back of the array, overcoming all the disadvantages of a traditional array where multiple sound sources emit from different locations. Instead, dispersion, phase, coherency and timing are all controlled and unified, ensuring the same sound is experienced by the audience, regardless of where they are standing. Whether placed on low frequency enclosures to form a dance stack or flown independently, the Nexus 6 provides intelligent performance and styling.

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.

Metric mm2	Imperial AWG	4 Ω load
2.50 mm2	13 AWG	18 m
4.00 mm2	11 AWG	30 m

Installation safety
To avoid mechanical hazards, please note the following:

Safety regulations vary in different regions. Full compliance with those regulations must be your priority
Installations must only be undertaken by fully qualified and experienced engineers/technicians who understand local regulations
This may include consulting a structural engineer before installation of wall brackets
Remember that all personnel have a duty of care to themselves, their assistants, the venue staff, and the public
Before lifting any part of the system above head height, check the whole rig for loose tools or other items that may fall and cause injury
Do not use a telephone (even if hands-free) whilst installing. Always concentrate fully on the installation operation
Do not install equipment that is worn, damaged, corroded, mishandled, or over-stressed in any way
Use only Void-approved mounting equipment and accessories
Secondary safeties should be provided in all instances where cabinets are flying or fixing overhead and should conform to local regulations

Ground Stacking

Step 1: Remove the backing plate from the Nexus 6 bracket by removing the M8 and M12 bolts from the bracket assembly.

Step 2: Remove all eight M8 bolts from the rear of the Nexus 6 loudspeaker.

Step 3: Attach the backing plate to the Nexus 6 ensuring that all eight M8 bolts are securely fastened.

Step 4: Carefully lower the Nexus 6 loudspeaker into position onto the bracket assembly.

Note: Nexus 6 loudspeakers are heavy and require a minimum of two people to lift. At this stage of the mounting procedure, it becomes necessary to have three people, two to lift the Nexus 6 loudspeaker and one to attach the bracket.

Step 5: With the lifting equipment still in place attach the M12 bolt to the bracket assembly.

Step 6: Adjust the vertical angle required using the datum line to select the required angle (shown here set to zero degrees indicated in yellow). The Nexus 6 bracket is capable of negative angle adjustment to point down (indicated in black) and positive angle to point up (indicated in red). The corresponding hole for each angle is indicated by that number and its color.

Step 7: Once the vertical angle has been selected attach the M8 bolt through the appropriate slot.

Step 8: Loosen, but do not remove, the M8 bolt from the rear of the bracket assembly.

Step 9: Adjust the horizontal angle of the Nexus 6 to the desired direction using the angle finder on the top of the bracket assembly.

Step 10: Secure the M8 bolt on the rear of the bracket assembly but ensure not to over-tighten the bolt as it may cause damage to the nut and bracket assembly.

Service

Void Nexus 6 loudspeakers should only be serviced by a fully-trained technician.

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

Return authorization
Before returning your faulty product for repair, please remember to get an 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 authorization 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 authorisation.

With twenty discrete proprietary drive units, Virtual Arc technology is implemented on every component to form a common virtual point source rearwards of the array resulting in a better and more controlled directivity, coherence, phase and time alignment between all components. The LF transducers shall be constructed on a cast aluminium frame, with a treated paper cone, 44 mm (1.7”) voice coil, wound with copper wires on a high-quality voice coil former and neodymium magnets, for high power handling and long term reliability. The HF transducers shall project their sound through a high precision constant directivity wave-guide, with a 76.2 mm (3”) baffle diameter, to achieve directivity pattern control between the different drivers with no cancellations and low distortion. Performance specifications for a typical production unit shall be as follows: the usable on-axis bandwidth shall be 78 Hz to 21 kHz (±3 dB) and shall average 50° directivity pattern on the vertical axis and 110° on the horizontal one (-6 dB down from on-axis level) from 1 kHz to 12 kHz; maximum SPL of 141 dB peak measured at 1 m using IEC268-5 pink noise. Power handling shall be 2700 W AES for the LF section at a rated impedance of 2 x 5.3 Ω and 640 W AES for the HF section at a rated impedance 2 x 4 Ω. The system shall be powered by its own dedicated power amplification modules with DSP management, from which crossover points will also be set, with the wiring connection via one Neutrik speakON™ NL8. The enclosure shall be of a special fiberglass composite with a smooth cellulose finish of any RAL color. The system shall be stack mounted with a dedicated stand or can also be suspended with a load-tested suspension system. The external dimensions of the enclosure shall be (W) 561 mm x (H) 1266 mm x (D) 430 mm (22.1” x 49.8” x 16.9”). Weight shall be 73.4 kg (161.8 lbs) including stand.
