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
-
Read these instructions.
-
Keep these instructions.
-
Heed all warnings.
-
Follow all instructions.
-
Do not use this apparatus near water.

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

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.

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
Pole Mounting
Parts required:
- 35 mm pole
- Step 1: Once the pole has been fitted to an appropriate mount raise the Air Stream loudspeaker into position.
- Step 2: Mount the Air Stream loudspeaker on the pole and rotate to the desired position.

Appendix
Architectural specifications
The loudspeaker shall be an active, three-way, bi-amped system consisting of a
high power 15” (381 mm) direct radiating reflex loaded Low frequency (LF)
transducer with a passive two way mid-high frequency section consisting of a
12” (305 mm) horn-loaded mid-frequency (MF) transducer and a 1.5” (38.1mm)
diameter exit, coaxial high frequency (HF) compression driver mounted on a
user rotatable waveguide, in an aesthetic designed enclosure. 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 it’s sound
through a user rotatable waveguide with a 200 mm (8”) baffle diameter.
Performance specifications for a typical production unit shall be as follows:
the usable on-axis bandwidth shall be 54 Hz to 20 kHz (±3 dB) and shall
average 45° directivity pattern on the vertical axis and 70° on the horizontal
one (-6 dB down from on-axis level). Maximum SPL shall be 133 dB peak (127 dB
continuous) measured at 1m using IEC268-5 pink noise. Power handling shall be
700 W AES for the LF at a rated impedance of 8 Ω and 500 W AES for the MHF at
a rated impedance of 8 Ω. The system shall be powered by its own dedicated
power amplification module with DSP management. The wiring connection shall be
via one Neutrik speakON™ NL4. The enclosure shall be of a special fibreglass
composite with a smooth cellulose finish of any RAL color. It shall contain
fixture points for a pressed, weather-resistant, steel powder-coated grille
with foam filter to protect the low-frequency transducer. The system shall be
stack mounted or can also be flown with a dedicated bracket. (W) 511 mm x (H)
743.5 mm x (D) 499 mm (20.1” x 29.3” x 19.6”). Weight shall be 42.5 kg (93.7
