provide you with useful and important information about your NEXT LA210x. Please
devote some time reading this manual and keep it at hand for future reference.
NEXT-proaudio is concerned with your safety and well-being so please follow all
instructions and heed all warnings. A better understanding of specic features of
the LA210x line array will help you to operate your system to its full potential. With
a continuous evolution of techniques and standards NEXT-proaudio reserves the

2.1 Introduction
2.2 Unpacking
Each NEXT LA210x line array element is built in Europe (Portugal) by NEXT-proaudio,
according to the highest standards and thoroughly inspected before it leaves the
factory. When unpacking your LA210x please examine it carefully for any signs of
transit damage and inform your dealer immediately if any is found.
NEXT-proaudio recommends that you retain the original packaging so that the
system can be repackaged in future if necessary. Please note that NEXT-proaudio
and its authorized distributors cannot accept any responsibility for damage to
any returned product using non-approved packaging.
2.3 Overview
The LA210x is a medium format three-way, coaxial, active line array element
designed to support a wide range of mid to large-sized touring applications and
installations where ease of use, from transportation to installation and rigging,
are critical. Built-in powerful DSP and amplication eliminates amplier racks, long
loudspeaker cables, and basic system calibration.
Custom made European transducers and a maximally optimized acoustic design
provide excellent sound delity at very high SPL levels. The LA210x features dual
10-inch (3-inch voice coil) neodymium woofers and a groundbreaking coaxial ring
radiator loaded by an exclusively developed OSWG waveguide. This acoustic
design delivers exceptional phase coherence and consistent coverage down to
300Hz and the most accurate transient reproduction.

Onboard, advanced, powerful 96kHz/40bit SHARC DSP engine, monitored by
built-in LCD screen with a preset loading encoder, can be remotely monitored and
controlled through ethernet by a PC. The full-featured PC-software automatically
identies each device and allows simultaneous control of multiple devices through
grouping facility. Everything you need to ne-tune the sound of your system is right
there.
The system is driven by an internal fan cooled 2000W 3-way ultra-ecient Class-D
amplier module releasing 1550W for LF section, 275W for MF section and 175W
for the HF section. Integrated universal mains power supply with PFC provides
consistency and optimum performance anywhere in the world.
The 3-point rigging system allows for quick and easy system setup. The LA210X
elements are easily connected via two front links. A rear centre link allows the user
to dene relative splay angles from 0° to 10°. The system will automatically lock to
the predened angles when lifting the array.

The ETH/AES connectors have two LED
indicators above them as shown in the diagram.
1. A standard Ethernet indicator and ashes
green when the connection is active.
2. This LED indicates the AESOP connection. If
the LED is inactive then AESOP is not selected.
If ashing yellow then AESOP is selected but
not locked. A solid yellow light indicates the
AESOP is selected and locked.
The status LED, see section 3.1, has the following meaning:
• Solid Green: analogue signal present
• Red Blinking: analogue input clip
• Solid Red: AES locked

11
IMPORTANT INFORMATION
Ethernet cables MUST be connected using the correct IN/OUT
connectors as shown in section 3.1. Failure to use the correct
connection will result in malfunction.
3.5 System Conguration
3 Cabling and Amplication
Note: Here the audio link between cabinets is shown using ethernet cable
for clarity. It is possible to add an XLR link between each cabinet as a
redundancy. If for any reason the network link fails the analogue link with
the XLR cable will automatically activate.
Below is an example of a conguration of the LA210x systems with LAs518A
subwoofers. For other examples of signal connection see section 3.4.

In this rst example the analogue cable is only supplied to the rst unit and from
there is distributed by AESOP using the ethernet cable.
It is also possible to connect AES directly (XLR cable) from a mixer, using the NEXT
AESOP Converter. The AESOP Converter will mix both AES and control signals into
one single AESOP ethernet cable.

Maximum Ethernet cable distance between devices is 70m. NEXT-proaudio
advises using CAT6 S/FTP cable
3.7 Power Distribution
When linking units for power distribution the following is the maximum units that
can be linked:
Voltage LA210x LAs518A
230 V Max 6 units Max 2 units
110 V Max 4 units Max 1 unit

In this example if the AESOP signal is interrupted for any reason, the DSP will
switch to the analogue signal instantly (fallback option must be enabled on X-NET
software). This method is highly recommended when redundancy is needed.

4 Mechanical Congurations
4.1 Rigging and Suspension Safety
• Before rigging or suspending NEXT LA210x 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 hardware that isn’t load rated or that its rating is not enough to
handle the system’s weight with a good safety factor (5 minimum). Don’t forget
that the hardware won’t just hold the systems weight. It must be sturdy enough
to handle dynamic forces, like winds for example, without any part deformation.
NEXT-proaudio advises customers to contact a licensed, professional engineer
regarding equipment installation.
• NEXT LA210x system installation should only be carried out by qualied personnel.
• Always use adequate protective clothing and equipment to prevent
possible injuries.
• Only install the systems on solid, levelled ground and isolate the surrounding
area during installation and operation, to prevent general public presence
near the systems.
• Be sure to understand and follow all local and national regulations regarding
equipment installation.
• Failure to comply with these instructions may result on injury or death.

Step 1:
Remove all rigging pins from the y
frame.
Step 2:
Lower the y frame into position
aligning the front holes of the y
frame with the rigging elements on
the LA210x.
4.1.1 Fly Frame
Step 3:
Insert both pins at the front of the
y frame.
Step 4:
Remove both pins from the rear
rigging assembly to allow to rear
link to swing free.

Step 5:
Rotate the rear link into position
and x it into place with the rear
pin on the y frame.
Step 6:
With the rigging in place it is now
possible to raise the assembly from
the shackle.
Step 7:
Remove the rigging pins from the
lower end of the rigging assembly.
Step 8:
Move the next cabinet into position
and x it at the front of the rigging
assembly with the rigging pins.

17
Step 9:
Remove both pins from the rear
rigging assembly on both cabinets
to release the rear link.
Step 10:
Rotate the rear link into position
and insert the pins on the right
hand side.
Note: The hole numbers
determine the splay
angle of the assembly.
To determine what angle
the cabinets should be
congured use EASE Focus.
Step 11:
Insert the left hand pin in the same hole
number as the right hand side to lock
the cabinet in position.
Repeat steps 7 to 11 for additional
cabinets as required.
