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. For EC Declaration of Conformity please go to: www.voidacoustics.com/eu-declaration-loudspeakers 1.4 UKCA marking For details of the UKCA marking go to: www.voidacoustics.com/uk-declaration-loudspeakers 1.5 Warranty statement Safety instructions - read this first 1. Read these instructions. 2. Keep these instructions. 3. Heed all warnings. 4. Follow all instructions. 5. Do not use this apparatus near water. 6. Clean only with a dry cloth. 7. Do not block any ventilation openings. Install in accordance with the manufacturer's instructions. 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.

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 12" ArcM 12 is unpowered, allowing it to integrate with touring operators' existing infrastructure. 3.3 Key features · High power 12" + 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 UG10569-2.1 - ArcM-12 User Guide V2.1 Page 6 3 About 3.4 ArcM 12 specifications Frequency response Efficiency1 Crossover point Nominal impedance Power handling2 Maximum output3 Driver configuration Dispersion Connectors Height Width Depth Weight Rigging Finish 60 Hz - 18 kHz ±3 dB 100 dB 1W/1m 1k2Hz (acoustic) 1 x 8 passive, 1 x 8 (LF) and 1 x 16 (HF) active 500 W AES 130 dB cont, 133 dB peak Coaxial 1 x 12" - 1 x 1.4" neodymium 80°H x 80°V 2 x 4-pole speakONTM NL4 330 mm (13") 550 mm (21.7") 463 mm (18.2") 19 kg (41.9 lbs) Integral top hat, type 80 mounting bracket Textured polyurethane 1 Measured in half space 2 AES2 - 1984 compliant 3 Calculated Figure 4.1: Horizontal directivity isobars Figure 4.2: Vertical directivity isobars UG10569-2.1 - ArcM-12 User Guide V2.1 Page 7 3 About 3.5 Dimensions 550 (21.7") 323 (12.7") 330 (13") 323 (12.7") 550 (21.7") 75 (3") 460 (18.1") 463 (18.2") 550 (21.7") 209 (8.2") 463 (18.2") 75 (3") 4X M8 Fixtures Figure 4.3: Dimensions 330 (13") UG10569-2.1 - ArcM-12 User Guide V2.1 Page 8 4 Cable and Wiring 4.1 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. 4.2 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.

UG10569-2.1 - ArcM-12 User Guide V2.1 Page 18 7 Appendix Architectural specification The loudspeaker shall be a passive, two-way, bi-amped system consisting of one high power 12" (304.8 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 in a 15 mm birch ply enclosure. The low frequency transducer shall be constructed on a cast aluminium frame, with a treated paper cone, 88 mm (3.5") voice coil, wound with aluminium 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 centre 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 60 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, 133 dB peak measured at 1 m using IEC268-5 pink noise. Power handling shall be 500 W AES at a rated impedance of 8 ; 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 a type 80 mounting point to suit portable and permanent applications. External dimensions of (W) 550 mm x (H) 330 mm x (D) 463 mm (21.7" x 13" x 18.2"). Weight shall be 19 kg (41.9 lbs). The loudspeaker shall be the Void Acoustics ArcM 12.
