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 this first

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. ollow all instructions.

5. Do not use this apparatus near water.

6. Clean only with a dry cloth.

8. Do not install near any heat source such as radiators, heat registers, stoves, or other such apparatus that produce heat.

9. 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.

10. Protect power cords from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit the apparatus.

11. Only use attachments and accessories specified by Void Acoustics.

12. 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.

13. Unplug the apparatus during lightning storms or when unused for long periods of time.

14. 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.

15. Since the mains power supply cord attachment plug is used to disconnect the device, the plug should always be easily accessible.

16. 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.

About

Welcome
Many thanks for purchasing this Void Acoustics ArcM 15 loudspeaker. 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.

ArcM 15 overview
The ArcM 15 has multiple working angles, allowing it to be used as a near field booth monitor or conventional stage wedge, as well as having the ability to be pole mounted or wall mounted for front-of-house purposes. In terms of mobility, measures have been taken to reduce weight, while maintaining an ergonomic design to appease manual handling requirements. Acoustically, FEA analysis has significantly reduced port noise and air distortion. The 15” ArcM 15 is unpowered, allowing it to integrate with our touring operators’ existing infrastructure.

Key features

• High power 15” + 1.4’’ coaxial neodymium transducer
• Two wedge operating modes (stage and nearfield monitoring)
• Integral pole mount for 35 mm diameter poles
• Low profile design for cleaner stage lines
• Ergonomically designed handles for easy manual handling
• External dimensions optimised for truck packing
• Hard-wearing polyurea finish
• Type 80 rear mounting plate for wall or ceiling fixing

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.

Appendix

Architectural specification
The loudspeaker shall be a passive two-way bi-amped system consisting of one high power 15” (381 mm) direct radiating reflex loaded low frequency (LF) transducer and 1.4” (35.56
mm) exit diameter (HF) co-axially-mounted neodymium high frequency (HF) compression transducer a 15 mm birch ply enclosure.
The low-frequency transducer shall be constructed on a cast aluminum frame, with a treated paper cone, 88 mm (3.5”) voice coil, wound with aluminum wires on a high-quality voice coil former, for high power handling and long-term reliability. The high-frequency transducer shall be bolted through the rear of the magnet structure belonging to the LF transducer to form a co-axial drive unit. The sound will project through a machined waveguide that exits in the center of the low-frequency transducer to use the 203.2 mm (8”) baffle diameter to achieve pattern control and low distortion.

Performance specifications for a typical production unit shall be as follows: the usable on-axis bandwidth shall be 50 Hz to 18 kHz (±3 dB) and shall average 80° directivity pattern for both horizontal and vertical axis (-6 dB down from on-axis level) from 1 kHz to 12 kHz; maximum SPL of 130 dB continuous, 134 dB peak measured at 1 m using IEC268-5 pink noise. Power handling shall be 500 W AES at a rated impedance of 8 Ω; crossover point at 1.2 kHz using a 2nd order filter (12 dB per octave). The system shall be powered by its own dedicated power amplification module with DSP management. The enclosure shall be of a trapezoidal asymmetrical shape constructed from a 15 mm
13-laminate birch plywood with a textured polyurea finish and shall contain fixture points for a pressed, weather-resistant, powder-coated steel grille with foam filter to protect the transducers. The cabinet shall have an integral pole mount socket and type 80 mounting point to suit portable and permanent applications. External dimensions of (W) 550 mm x (H) 371 mm x (D) 530 mm (21.7” x 14.6” x 20.9”). Weight shall be 22.5 kg (49.6 lbs).The loudspeaker shall be the Void Acoustics ArcM 15.
