useful and important information about your NEXT LA26/LAs15(A) element. Please devote some time reading
this manual, and keep it at hand for future reference. NEXT-proaudio is concerned with your safety and well-be-
ing, so please follow all instructions and heed all warnings. Also, a better understanding of some specic
features of the LA26/LAs15(A) line array element will help you to operate your system to its full potential. With

UNPACKING
Each NEXT LA26/LAs15(A) line array element is built in Europe (Portugal) by NEXT-proaudio, to the highest
standard and thoroughly inspected before it leaves the factory. When unpacking the NEXT LA26/LAs15(A),
examine it carefully for any signs of possible transit damage and inform your dealer immediately if any such
damage is found.
It is suggested that you retain the original packaging so that the system can be repacked in the future if
necessary. Please note that NEXT-proaudio and its authorized distributors cannot accept any responsibility for
damage to any returned product through the use of non-approved packaging.
LA SERIES OVERVIEW
The LA26, LAs15 and LAs15A are part of the NEXT-proaudio LA series. LA26 it’s an ultra-compact line array
element that incorporates an impressive battery of high technology features that makes it able to achieve an
unprecedented level of performance on compact line array systems.
The LA26 houses two 6.5" neodymium Planar Diaphragm drivers located in the side walls of the HF Oblate
Spheroidal Waveguide, a 2" diaphragm HF neodymium driver and a passive network crossover presenting a
nominal input impedance of 16.
The LF Planar Diaphragm drivers, and its special placement, integrated on the Spheroidal Waveguide,
reduces the cavity eect, associated with traditional cone speakers, radiating sound energy smooth and evenly
over the entire coverage area. This special arrangement perfectly combines the HF and LF acoustic centres to
generate precisely coherent wave fronts uniformly spread in the horizontal plane and precisely coupled in the
vertical plane.
The LA26 was designed to be incredibly versatile solving the needs of production companies, rental
houses, theatres, houses of worship, working as main system, front ll, side array or as complement of
larger-scale LA systems.
For low frequency extension LAs15 or LAs15A, active subwoofer, can be used. The LAs15A is capable to
process and power up to three LA26 passive line array elements.

SAFETY FIRST
• Try not to operate the LA26 or LAs15(A) under heavy rain or moisture.
• Do not expose the systems to extreme heat or cold conditions to prevent component damage.
• Never place your speaker in a way that prevents air ow near to the side bass reex ports. A minimum clear-
ance distance of 10cm should be kept between the ports and any near surface.
• Place cables in a way that they do not present a trip hazard.
• Do not place any objects on top of the speaker, they can fall accidentally and cause injuries.
• Do not attempt to move the speaker while connected.
• Do not attempt to service the speaker beyond what is described in this manual. All other service or repair of
this product should be carried only by qualied personnel.
• To prevent electric shock, do not use any extension cord, receptacle or other outlets where the blades of the
connectors cannot be fully inserted.
• Do not operate the unit for an extended period of time with the sound distorting.
• When connecting several speakers, make sure that all the speakers have the same polarity and that the ampli-
er is not overloaded.
• Always ensure that the oor or structure where the stack will be placed is even and can withstand the weight
of the complete stack.
• Do not stack speakers too high, especially outdoors where winds could topple the stack.
RIGGING AND SUSPENSION SAFETY CONSIDERATIONS
• Before rigging or suspending NEXT LA26/LAs15(A) systems, inspect all components and all hardware for any
signs of damage or missing parts.
• If you nd any damaged, corroded or deformed parts, do not use them, replace them immediately.
• Do not use any hardware with a safety factor lower than 4. Don’t forget that the hardware won’t just hold the
systems weight, it has to be sturdy enough to handle dynamic forces like winds with no deformation.
• NEXT LA26/LAs15(A) system installation should only be carried out by qualied personnel.
• Always use adequate protective clothing and equipment to prevent possible injuries.
• Be sure you understand all local and national regulations regarding equipment installation.
• NEXT-proaudio is not responsible for any rigging equipment or accessories provided by third party manufac-
turers. Ensure that the Working Load Limit (WLL) of the whole rigging parts is respected.
• Failure to comply with these instructions may result on injury or death.
