SAFETY FIRST
Read User Manual before deployment.
Before use of enclosed speaker system, please ensure that anyone involved in system
deployment understands the rigging safety rules as described in the speaker system
User Manual. Failure to do this exposes people to potential injury or death.
NS-1 is a dedicated calculation software that will give you vital information on your
coverage, but also your load limitations, rigging, and mechanics.
DO NOT PROCEED if you have not run NS-1 prior to implementing STM.
Mounting precautions
• Choose mounting hardware and an installation location that can support the weight of
the speaker system.
• Do not use speaker handles or any other rigging methods than those specified by
Nexo for suspended installation.
• Do not expose speaker system to excessive dust or vibration, or extreme cold or heat
to prevent possibility of component damage.
• Do not place the speaker system in an unstable position from which it might fall
accidentally.
Health and Safety
• Please ensure you follow all your local Health and Safety regulations when using
Nexo STM and any other Nexo products.
• Make sure all people on-site are approved and wearing the required PPE .
• Respect Legislation on heavy lifting limitations. One STM M46 or B112 module
weighs 59Kg (2 person lift!)
• Nexo supplies a list of approved accessories. Please do not use any other accessories,
for your own and other’s safety.
• STM is capable of delivering extremely high sound pressure levels. Please ensure that
you are complying to local legislation and that personnel are not exposed to
dangerous levels and are wearing the necessary ear protection.
• When implementing STM, please take into account the effect of wind on the load. In
case of wind exceeding Beaufort 8, clusters must be lowered at ground level.

CONNECTING STM CABINETS
Below table describes connection of one STM M46 or B112 to subsequent module.
REAR VIEW
LEFT VIEW
• Lower cabinet into position,
aligning side locking slots on
both sides of the cabinets.
• Push REDLOCK™ into
“LOCK” position.
• Ensure handle is locked.
• Check side locking pins are
flush to the rigging plates on
both sides of the cabinet.
• Slide piston to lower cabinet,
and insert quick release pin.
• Check quick release pin is
locked
Operation
Step 1
Step 2
Step 3
Step 4
• Lift speaker
• Connect speaker cable
Step 5
• Set speaker angles as specified
from NS-1 Software
• Rotate piston lock handle to
“OPERATION” position
(vertical).
• Back to step one for subsequent
cabinet.

Procedure description
RIGGING PROCEDURE
• Install XBOW on to each top
module, lock into place with two
spring locks and rear steel pin.
• If 2 or 3 columns: join XBOW’s
together at front and rear with
XCOUP2 or XCOUP3 coupling bars,
and secure in place with steel pins.
Insert MBEAM at the middle of the
XCOUP2 or XCOUP3 coupling bars,
and secure in place with spring locks.
• Install top rigging components as in
page 4, including laser inclinometer
and Compression Chain or Chain
Lever Hoist.
• Attach motor(s) and lift
• Connect subsequent STM modules
(refer page 5)
• Once all modules are connected,
install BTBUMPERs underneath
bottom modules, align side-pins, and
push “REDLOCK” to the “LOCK”
Position
Connect BTBUMPERs to bottom
module piston and secure in place
with locking pin.
• If 2 or 3 columns: join
BTBUMPER’s together with
BCOUP2 or BCOUP3 coupling bar.
• Attach Compression Chain or Chain
Lever Hoist to BTBUMPER or
BCOUP2 or BCOUP3 center point.
• Before applying compression, ensure
all piston locking handle are in
“OPERATION” position – ie vertical
– and all angles set at correct value.
• If 2 motors: bring the array angles to
compression with rear motor or
Chain Lever Hoist, ensure
compression is fully applied on all
cabinets, fly STM to operating height
and adjust bumper angle with motors
• If 1 motor: bring the array angles to
compression and adjust bumper angle
with Chain Lever Hoist, ensure
compression is fully applied on all
cabinets, fly STM to operating
height.
2 motors, Kelping beam and Compression Chain
2 motors and Chain lever Hoist
1 motor and Chain Lever Hoist

DISMANTLING
De-rigging
De-rigging is as simple as following rigging procedures in reverse order:
• Lower the array slowly, until the array is close to the floor.
• Release compression slowly, until the array is hanging vertically.
• Remove the compression chain, BTCOUP2/3 if required, and BTBUMPERs.
• Remove all speaker cables within reach, without climbing the array.
• Set all piston taps to the STORAGE position.
• Position dollies below the bottom module and lock the wheel brakes.
• Lower the arrray into position on the dollies.
• Push REDLOCK to LOCK position on the bottom cabinets.
• Release the upper array from the stacked cabinets by releasing the REDLOCK and the
rear steel pin on the cabinet above the stacked boxes.
• Lift remaining array, release wheel brakes and remove stacked modules.
• Repeat as required.
• Remove rigging components.
