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. 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 under 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 the 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.

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 is needed to cause such damage. Avoid prolonged exposure to the high sound levels from the loudspeaker.

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.
• Air Motion loudspeakers are 3-way, bi-amplified. They require two amplifier channels to drive them via 4-core speakONTM NL4 cables. We suggest using the following maximum copper cable lengths to keep level losses below 0.6 dB.

Installation safety

• To avoid mechanical hazards, please note the following.
• Safety regulations vary in different regions. Full compliance with those regulations must be your priority
• Installations must only be undertaken by fully qualified and experienced engineers/technicians 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 staff 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) whilst installing. Always concentrate fully on the installation operation
• Do not install equipment that is worn, damaged, corroded, mishandled or over-stressed in any way
• Use only Void-approved mounting equipment and accessories
• Secondary safeties should be provided in all instances where cabinets are flying or fixing overhead and should conform to local regulations

Mounting the U Bracket

Parts required:

Black – IT1083

1. Step 1: Lay a soft lint-free rug clear of debris on a work surface to avoid damage to the loudspeaker. Place the Air Motion with the horns face down and remove all four M8 socket cap Allen bolts from the 12” LF driver.
2. Step 2: Remove the 12” LF driver from the main bracket taking care not to place any strain on the cable connecting to the 8” mid driver.
3. Step 3: Insert the U bracket for the desired orientation. Then insert the M12 x 70 mm bolt through the non-threaded side of the U bracket, 12” LF driver side, and tighten the bolt. Then tighten the M12 Aerotight nut to the 8” mid driver side.
   • Note: The U bracket is threaded for the bolt on one side only. Ensure that the threaded side faces the 8” MHF driver and the non-threaded side faces the 12” LF driver.
4. Step 4: Finally reattach the 12” LF driver with the four M8 socket cap Allen bolts, taking care not to over-tighten.

Parts required:

Appendix

Architectural specifications

• The loudspeaker shall be an active, three-way, bi-amped system consisting of a high power 12” (305 mm) isometric conical horn loaded low frequency (LF) transducer with a passive two-way, mid-high frequency section consisting of an 8” (200 mm) isometric conical horn loaded mid-frequency (MF) transducer and a 1.5” (38.1 mm) diameter exit high frequency (HF) compression driver.
• Low frequency (LF), mid and high frequency (MF and HF) transducers shall be enclosed in separate and independent moulded conical fibreglass cabinets with a smooth, high gloss finish of any RAL colour.
• The LF and MF transducers shall be constructed on a cast aluminium frame, with a treated paper cone, 63.5 mm (4”) for the LF and 50.8 mm (2”) for the MF voice coil, wound with copper wires on a high-quality voice coil former, for high power handling and long-term reliability. The HF transducer shall project its sound through an elliptic conical waveguide with a 200 mm (8”) baffle diameter.
• Performance specifications for a typical production unit shall be as follows: the usable on-axis bandwidth of 140 Hz to 20 kHz (±3 dB), with an average 50° directivity pattern on the vertical axis and 60° on the horizontal one (-6 dB down from on-axis level) from 1 kHz to 12 kHz; maximum SPL of 137 dB peak, measured at 1 m using IEC268-5 pink noise. Crossover points shall be at 140 Hz and 600 Hz for the LF section and 1.7 kHz passive for the MHF. The system shall be powered by its dedicated power amplification module with DSP management, with the wiring connection via two Neutrik speakON™ NL4; one for input and one for linking out to another speaker.
• The aesthetically designed enclosures shall be bolted onto a powder-coated steel frame using a minimum of four M8 bolts per horn. This frame aligns the horns in the correct acoustic space to achieve good directivity across the loudspeaker system’s entire spectrum. The frame will incorporate mounting holes for a ‘U’ bracket fixture for fitment to ceiling and wall mounting brackets. The external dimensions of the enclosures and frame shall be (W) 854 mm x (H) 672 mm x (D) 658 mm (33.6” x 26.5” x 25.9”). Weight shall be 35.4 kg (78 lbs).
