IMPORTANT SAFE INSTRUCTIONS
Before using our product, be sure to carefully read the manual and safe Instructions. Keep this document with the device all
time.
1 Read these instructions.
2 Keep these instructions.
3 Heed all warnings.
4 Follow all SAFETY INSTRUCTIONS as well
DANGER and OBLIGATION warnings.
5 Only use attachments / accessories
specified by the manufacturer.
6 SAFETY STATEMENT FOR RIGGING. This
Statement assumes that the owners and/or
users are familiar with the rigging techniques
and safety recommendations outlined in this
manual. Many issues of crucial concern,
such as the determination of
appropriateness and condition of venue
rigging points, cannot be addressed here.
Therefore, the user must assume all
responsibility for the appropriate use of
Rigging systems in any particular location or
circumstance.
7 PERSONNEL HEALTH AND SAFETY.
During installation and set-up personnel
should wear protective headgear and
footwear at all times. Under no
circumstances personnel should climb on
the loudspeaker assembly.
8 INSPECTION AND MAINTENANCE. The
rigging systems are an assembly of
mechanical devices, and are therefore
subject to wear and tear over prolonged use,
as well as damage from corrosive agents,
extreme impact, or inappropriate use.
Because of the safety issues involved, all
system components must be inspected
before use in order to detect any possible
defects.
9 LOAD RATING AND SPECIFICATIONS.
Load capacity and setup safety limits when
flying or stacking a loudspeaker assembly
should be strictly followed according to the
instructions outlined in this manual.
10 LOCAL REGULATIONS. The suspension of
large, heavy objects in public places is
subject to numerous laws and regulations at
the national/federal, state/provincial, and
local levels. It is the user’s responsibility to
verify that any overhead suspension of
TECNARE systems has been made in
accordance with all applicable local
regulations in any particular circumstance or
venue conforms to all applicable laws and
regulations in force at the time.
11 FLYING A LOUDSPEAKER SYSTEM
Always verify that nobody is standing
underneath the loudspeaker assembly when
it is being raised. As the system is being
raised check each individual component to
make sure that it is securely fastened to the
component above. Never leave the system
unattended during the installation process.
As a general rule, EXEL ACOUSTICS
recommends the use of safety slings at all
times.
12 STACKING A LOUDSPEAKER SYSTEM.
Do not ground stack the system on unstable
ground or platform. If the system is ground
stacked on a structure, platform, or stage
always check that the latter can support the
total weight of the system. As a general rule,
EXEL ACOUSTICS recommends the use of
safety straps at all times
13 When a loudspeaker assembly is deployed
in an open air environment, wind effects
should be taken into account. Wind can
produce dynamic stress to the rigging
components and suspension points. If the
wind force exceeds 6 B (Beaufort scale) it is
highly recommended to lower down and/or
secure the loudspeaker assembly.
14 REPLACEMENT PARTS. Any component
found to be defective, or any safety-related
component you even suspect might be
defective, should be replaced with the
equivalent, approved part. Parts specific to a
rigging system should be ordered directly
from Exel Acoustics. No attempt should be
made to substitute what appears to be
equivalent or “mostly the same” generic
replacements. Therefore, EXEL
ACOUSTICS is not responsible for problems
caused by components that were not
supplied by EXEL ACOUSTICS.

2THV21-18VR MULTIPURPOSE GRID
The THV21-18VR grid is made of steel and has been designed to fly or stack mixed arrays
of CLa21s and SW18VRs enclosures without transition hardware.
The THV21-18VR is a square frame fitted with the following elements:
▪Four quick-release pins
▪Four rotating Guide-link
The THV21-18VR grid accommodates a variety of pickup configurations with its 21 center
pickup points and . To add tilt to the array, attach motors to the front and rear of the center point
plate. If just one motor is available, attach it to one of the 19 center pickup points offset from the
center of the grid to achieve the desired tilt. The grid can also be oriented to provide either
maximum array downtilt or maximum array uptilt
Fig.1 THV21-18VR grid
CAUTION: Always use the quick-release pins included with the THV21-18VR grid to
secure the attached CLa21 or SW18VR. Do not use the magnetic quick-release pins included
with CLa21 or the SW-18VR in the grid as they are shorter and will not lock in place.
CAUTION: Always use properly rated rigging hardware. The THV21-18VR have holes in
the center pickup point plate of 24mm diameter and you should use an adequate shackles for
its pickup points with enough load capacity.

3ASSEMBLING AN ARRAY
3.1 Modelling and inspection
Before installing the systems it is a good idea to run a simulation with EASE Focus software
which will assist the user to:
▪Determinate the number of CLa21 enclosure
▪Calculate the THV21-18VR site angle and the splay angles
▪Check the mechanical conformity of the system.
It is extremely important to assure that each and every one of the structures involved in the
process hanging are capable of supporting a superior load than that of the complete system. As
an extra precaution, careful inspection of the attachment points is advised before flying,
particularly in older venues or those hosting frequent events using large sound and lighting
systems.
Inspection is the next step. Key components must be inspected before each use. Such
inspection includes examination of all load-bearing components for any sign of undue wear,
twisting, buckling, cracking, rusting, or other corrosion.
Particular attention should be given to screws, bolts, and other fasteners to make certain
the fittings are tight and secure. Metal seams and welds should be examined for any sign of
separation or deformation.
Rigging should be carried out by expert familiar with the way the system function and their
characteristics.
3.2 Grid orientation for Flown Arrays
The THV21-18VR grid can be oriented to locate the array’s center of gravity closer to the
front or rear of the grid, to achieve a few more degrees of downtilt or uptilt for flown arrays. The
grid’s orientation is also important when accommodating groundstacks with downtilt or uptilt
(see “Grid Orientation and Groundstacks” on page 32).
To add tilt to the grid, you can attach two motors to the front and rear of the centre
pickup point plate. If just one motor is available, attach it to one of the 19 centre pickup
points offset from the centre of the grid to achieve the desired tilt.

THV21-18VH GRID ORIENTED FOR MAXIMUM ARRAY DOWNTILT
When the THV21-18VR grid is oriented forward with the attached loudspeaker near the
front of the grid, the array’s centre of gravity is located closer to the front of the grid, thereby
allowing the rear pickup points to achieve maximum array down-tilt.
Fig. 3 THV21-18VR Grid oriented for maximum array downtil
THV21-18VH GRID ORIENTED FOR MAXIMUM ARRAY UPTILT
When the THV21-18VR grid is oriented rearward with the attached loudspeaker near
the rear of the grid, the array’s center of gravity is located closer to the rear of the grid, thereby
allowing the front pickup points to achieve maximum array uptilt.

3.3 Guide links
CLA21 GUIDE LINKS ARM
CLa21 is equipped with four captive guide links arms that link to adjacent units of CLa21 or
SW-18VR in flown and groundstacked arrays. Located at the top corners of the cabinet, the
guide links arms extend up and into the link slots of the cabinet above it (or into the link slots of
the THV21-18VR). The links extend and retract with recessed knobs and are secured with
quick-release pins: one each in the top and bottom cabinet.
CLa21 loudspeaker ships with eight quick-release magnets pins.
Fig 5 CLa21 Guide link arms with quick release pins
CAUTION: CLa21 guide links arms must be secured with the included quick-release
magnets pins. At not time should the weight of the enclosure rest on the knobs when the link
are fully extended (without the pins inserted). The purpose of Knobs of guide links arms is only
extend and retract the guide links arms.

CLA21 SPLAY ANGLES
Front guide links arms attach at splay angles of 0 or +4 degrees. However, the front guide
links should almost always be attached at 0 degrees, to ensure that coverage between linked
cabinets is continuous. When attached at 0 degrees, the front guide links arms act as a pivot
point between the linked CLa21s, with the splay angle between the units determined by the rear
guide link positions. In this way have angles available from 0 to 8 degrees.
Fig 6 CLa21 Guide link arms setting at 0 degrees
When attached at +4 degrees, the front guide links arms add 4 degrees to the splay angle
configured with the rear guide links, making it possible to achieve splay angles of 9 to 13
degrees. To stow the front guide Links, move them all the way down to STOW and pin them.
CLa21 Front guide link label with angle

Operation Manual
17
Wide splayed angles of 9 to 15 degrees should only be used for downfill coverage, or for
steering coverage away from structures like balconies.
The rear guide links arms determines the vertical splay angle (whether stacked or flown),
as a function of the hole where the pin is attached. Rear guide links arms attach at splay angles
of 0 to 9 degrees
Stack or flown mode is determined by the position in which the guide arm is attached to
the upper cabinet.
For flying the boxes and defining the splay angle, the pin must be inserted in the sliding slot of
guide links arms whereas for stacking, the pin goes through the fixed hole of the guide links
arms. For flown, after the stack is lifted, the loudspeakers rotate on the axis of the front link
arms and the rear guide link arms slide into position as the weight of the of the loudspeakers
causes the cabinets to shift
.
Fig. 8 Rear guide link arms (A) Stack Mode (B) Flown Mode
To aid the setting of guide links arms, each hole is labelled with the splay angle between
cabinets. As the links are moved down, the splay angle increases. To fit the guide links arms
into the hole, highly resistant 10mm quick-release magnet pins are used.
To stow the rear guide links arms, move them all the way down to STOW and pin them to
the 0 degree pin position.

When the front links guide are attached at +4 degrees, the pins must be inserted in the
holes which the splay angles are labeled in brackets.
The splay angles listed on the guide link labels are for relative angles between the center
axes of the linked units. For example, setting the guide links to 5 degrees yields a 5-
degree downtilt of the lower unit to the upper unit. How the loudspeakers relate to the
floor, stage, and seating angles in the venue depends on the orientation of the grid, the
angles of the loudspeakers in the array above them, and other factors. EASE Focus
prediction software should be used to calculate optimum splay angles for loudspeakers
and to predict coverage patterns for arrays.
CAUTION: CLa21 guide links arms must be secured with the included quick-release
magnets pins. At not time should the weight of the enclosure rest on the knobs when the link
are fully extended (without the pins inserted). The purpose of Knobs of guide links arms is only
extend and retract the guide links arms.
CLA21 SPLAY ANGLES FOR TOP FLOWN CABINETS
When flying CLa21 below THV21-18VR grid, splay angles of -6 to 7 are possible for top
cabinet with the following guide links arms configurations.
The holes which the splay angles are labeled in brackets.
When flying CLa21s from the THV21-18VR It is recommended to select the 6º angle on
the Cla21 intended to be linked to the THV21-18VR. In this way the Cla21 axis will be
parallel to the THV21-18VR
CAUTION: To link the THV21-18VR and Cla21 the quick-release pin-lock must always be
done by placing it on the rear guide arm in stack mode (fixed) position.
