4.2 Nexus 6 overview
Aimed at the larger venue, the radical styling of the Nexus 6 is born from the innovative
internal layout of its twenty transducers. The multi-way Nexus 6 consists of no less than
twelve 6.5” low frequency drivers and eight 1” high frequency compression drivers housed in
a sculpted fibreglass enclosure that can be ground stacked on low frequency enclosures, or
suspended independently using the optional proprietary Void suspension system.
Virtual Arc technology is implemented on every component to form a common acoustic
centre, or virtual point source, that exists rearwards of the array. This approach overcomes all
the disadvantages that compromise a traditional array of multiple sound sources emitting from
dierent locations. Dispersion, phase, coherency and timing are all controlled and unified due
to the common acoustic feed point and multi-channel access. Virtual Arc technology ensures
that the same experience is had by all that are in the throw of the Nexus 6, wherever they are,
due to its wide and controlled dispersion. Total summation of all the components in each
passband can also take place within the Nexus 6, allowing for much higher eciency, greater
output and improved reliability due to reduced component stress.
The Nexus 6 oers excellent value for money when compared to the array of enclosures
normally required to achieve the same dispersion. Whether placed on low frequency
enclosures to form a dance stack or suspended independently, the Nexus 6 brings the
performance and styling of the future to the here and now.

5.1 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.
5.2 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.

6 System design
6.1 System design principles
Nexus 6 loudspeakers can be arrayed as a single pair facing forward to provide a wide
stereo image.
For permanent installation, it is recommended to fly the Nexus 6 loudspeakers for more even
coverage. This also allows co-located low frequency enclosures in a single block, increasing
sensitivity and providing more consistent bass coverage.

Figure 6.2: Permanent installation

Nexus 6 User Guide V1.1
Page 14
6 System design
6.2 Loudspeaker placement and positioning
When deploying Nexus 6 loudspeakers, it is important to
consider the speakers’ vertical position to maximise coverage
in the vertical axis. Horizontal loudspeaker dispersion figures
dictate the coverage of the loudspeaker, left to right, to the
-3 dB points. The same can be said for the vertical dispersion
figure, but when applied to a listening area, this figure dictates
the audience area coverage front to back.
Vertical dispersion is often overlooked or not assessed
properly, resulting in ineciently deployed loudspeaker
systems that require more fill loudspeakers than are necessary
to achieve required coverage. Following are some basic
guidelines when considering the vertical position of your
Nexus 6 loudspeaker.
With optimum vertical positioning and aiming applied the
loudspeaker system can be used at maximum eciency. With
a point source loudspeaker in this configuration the speaker
is placed 2m-4m from the ground, aimed half way to two thirds of the way back from the
audience area, as shown in figure 6.4. The applied aiming reduces unwanted reflections from
the ceiling and directs the highest energy concentration to the audience area requiring it most.
This is the most desirable position for the loudspeakers in this example.
Figure 6.4: Correct loudspeaker placement

Figure 6.3b: Horizontal dispersion (top view)

6 System design
A multi-point loudspeaker system in a club/bar environment can be very pleasing for the
listener. However, it’s important that the processes applied to previous examples are still
implemented. In figure 6.5 you can see the loudspeakers have been positioned and aimed
optimally. When deploying a multi-point loudspeaker system, extra consideration must be
taken to counter unwanted room eects. Careful positioning and aiming of loudspeakers will
minimise room eects, while maintaining even coverage throughout the audience area.
Figure 6.5: Multi point loudspeaker arrangement
Audience
Stage
Figure 6.6: Correct horizontal dispersion
In the horizontal plane rotate the Nexus 6 loudspeaker toward the audience area at an angle
such that the centre line of the dispersion from each loudspeaker meets about two thirds of
the way towards the rear of the audience area. This will help provide a wider coverage and
result in more of the power being used usefully.

Nexus 6 User Guide V1.1
Page 16
Figure 6.8: Incorrect loudspeaker placement
Figure 6.9: Incorrect loudspeaker placement
Figure 6.9 shows the loudspeaker vertical position is optimal for the audience area but the
user hasn’t applied an aiming angle. In this case, a large portion of energy is directed at the
ceiling that could result in reduced intelligibility and unwanted room acoustic characteristics.
The shallow angle of attack will also induce refraction issues on a hot dance floor, leading to
reduced HF penetration at mid and far distances, again reducing intelligibility and coherence.
In figure 6.8 the loudspeakers vertical positioning is too low for the audience area. Mid
and high range frequencies are absorbed by the first two rows of people, resulting in poor
coverage and potential acoustic issues from room reflections.
Audience
Stage
Avoid directing the Nexus 6 loudspeakers straight forward. This will result in a proportion of the
power being directed towards the walls, creating possible reflective issues, as well as causing a
gap in coverage at the centre of the audience area.

• 6 mm Allen key
7.1 Installation safety
To avoid mechanical hazards, please note the following:
• Safety regulations vary in dierent regions. Full compliance with those
regulations must be your priority
• Rigging must only be undertaken by fully-qualified and experienced riggers 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, to their assistants, to the
venue sta and to 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) while rigging. Always concentrate fully on the
rigging operation
• Do not rig equipment that is worn, damaged, corroded, mishandled or over-stressed in any way
• Use only Void-approved mounting equipment and accessories.
