4.1 Welcome

Many thanks for purchasing this Void Acoustics Arcline 218. We truly appreciate your support. At Void, we design, manufacture and distribute advanced professional audio systems for the installed and live sound market sectors. Like all Void products, our highly skilled and experienced engineers have successfully combined pioneering technologies with groundbreaking design aesthetics, to bring you superior sound quality and visual innovation. In buying this product, you are now part of the Void family and we hope using it brings you years of satisfaction. This guide will help you both use this product safely and ensure it performs to its full capability.

4.2 Arcline 218 overview

As a new addition to the Arcline family, the Arcline 218 enhances our line array enclosure oering and is optimised for use in theatres, event spaces and outdoor areas. Developed using extensive Finite Element Analysis (FEA) modelling, the result is maximum performance from the smallest footprint. This FEA modelled hyperboloid porting also signiﬁcantly reduces port noise and air distortion, while the advanced internal brace design brings a noticeable weight reduction and increased cabinet rigidity.

Arrayable with the Arcline 118 in multiple conﬁgurations, including cardioid, this brings a new level of versatility to the audio arena. Aesthetically-pleasing cable management when running in cardioid conﬁguration is also now possible with the front speakONTM chassis. If manpower is limited for the setup, an Arcline system can be arrayed by one person independently and given that each Arcline product can be cased and transported in multiples, this radically reduces setup time. The subs have been speciﬁcally designed with the ease of touring in mind, with advantageous features including: ergonomic handle cup design; external dimensions optimised for truck packing; and a hardwearing polyurea ﬁnish for a long life on the road.

4.3 Key features:

• Two high power 18” neodymium transducers

• Front and rear speakONTM chassis

• New ergonomic handle cup design

• Arrayable in multiple conﬁgurations, including cardioid

• External dimensions optimised for truck packing

• Hard-wearing polyurea ﬁnish

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 Operating modes

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

6.2 Typical modes

Although the modes of arrangement shown here are typical operating modes for low frequency enclosures, the Arcline 218 system’s symmetrical 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.

Figure 6.1: Operating modes

Arcline 218 User Guide V1.0

6.3 Cardioid modes

As low frequency enclosures are omnidirectional, rear projection can cause a range of diculties. If there is a wall behind the array, the sound wave can reﬂect o the surface and may cause cancellation in front if it arrives out of phase with the wave from the source. Another problem may occur during performances where an array is deployed in front of the stage, possibly creating a maximum sound pressure level that makes it dicult for some performers. Utilizing a cardioid conﬁguration will reduce stage noise and increase forward directivity at the cost of more loudspeaker power.

The Arcline 118 and Arcline 218 can be arrayed in a variety of cardioid conﬁgurations depending on the requirements of the system with a few examples shown below. For other layouts or more information, please contact your local Void distributor/dealer.

6.3.1 Symmetrical

A symmetrical layout, as shown in ﬁgure 6.2a and

6.2b, will reduce rear rejection.

Note that ﬁgure 6.2a, an Arcline 218 stacked vertically above an Arcline 118, can be top heavy and may have a danger of falling. It would be advisable in this conﬁguration to ensure that the array is securely strapped down.

6 Operating modes

6.3.2 Asymmetrical

In the case of an asymmetrical layout the cancellation has the eect of directing the sound away from the loudspeaker that has been inverted. So in the case of the arrangements shown in ﬁgure 6.3 the sound level to the right will be reduced.

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.

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.

7.1 Wheel removal
