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 this first

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.

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.

Arcline 118 overview

Optimised for use in theatres, event spaces and outdoor areas, the Arcline 118 has been developed using extensive Finite Element Analysis (FEA) modelling to offer maximum performance from the smallest footprint. FEA-modelled hyperboloid porting 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 218 in multiple configurations, including cardioid, this brings a new level of versatility to the audio arena. Aesthetically- pleasing cable management in cardioid configuration is possible via the front speakON™ chassis. Arcline systems can be arrayed by one person independently and each Arcline product can be cased and transported in multiples, radically reducing setup time.

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	8 Ω load	4 Ω load	2 Ω load
2.50 mm2	13 AWG	36 m	18 m	9 m
4.00 mm2	11 AWG	60 m	30 m	15 m
