1 INTRODUCTION
The aim of this manual is to enable users to use the “Outline GTO Array” system
correctly and take all the measures and have all the means necessary for safe long-
lasting use of the entire system.
The user is intended as being: the purchaser, the site manager, personnel responsible
for transport and flying, warehouse staff, those responsible for maintenance and
operators involved in general.
The “Outline GTO Array” system consists in a rigging device, which will be called
“frame”, and a number variable (maximum twenty-four) “GTO” model loudspeaker
enclosures, which will be called “elements”. The latter are connected in series below the
frame.
This document must be kept by the person responsible, in a suitable place, in order to
always be available for consultation. In the event of loss and/or damage, a new copy can
be requested from Outline s.r.l. - Via L. da Vinci N°56, 25020 Flero (Brescia), Italy.
The rigging accessories described in this manual are manufactured, certified and marked
in compliance with Community Directive 89/392/CEE, enacted with DPR 459 of 24/07/96
and later amendments 91/368/CEE, 93/44/CEE and 93/68/CEE.
Interested parties are urged to read and divulge the instructions in this manual, in order
to avoid damage to the system and incorrect use.
Outline s.r.l. declines any responsibility due, for example, to incorrect use, use on behalf
of inexperienced staff, use of non-original spare parts and unauthorized modifications.
The user is also obliged to maintain in good conditions the marking on the structure
(name of manufacturer, year of construction, series/model).
2 DESCRIPTION OF THE RIGGING DEVICE
(FRAME)
The rigging frame is shown in the following illustrations.
Operating configuration. Transport configuration.
Figure 1 – Frame
In a few words, the frame is made up of two main elements that are interconnected via a
pinion, forming the load-beating structure, and a series of accessories, which are:
oa quick-locking pin with button for fixing the cantilever arm;

USER’S MANUAL FOR MAINTENANCE, CONTROL & INSTALLATION OF THE
“OUTLINE GTO ARRAY” – Translation of the original instructions
Page 4/31
ofour brackets and quick-locking pins with buttons for connecting the first element of
the array (GTO loudspeaker enclosure);
odue 6.5 t (centre) shackles and four 3.25 t (side) shackles for hooking on the motor
hoists;
oa shackle for connecting the cable support elements.
Figure 2 - Frame with accessories.
The cantilever beam can be folded away to reduce the hardware’s footprint during
transport; during work, on the other hand, it must be kept extended and locked with the
relative pin (Figure 1).
Both the main elements of the frame are constructed by assembling (welding) a series of
specially machined and manufactured in S355JR steel beams and plates. The frame was
conceived for use in Flying configuration, with the loudspeakers (a maximum of twenty-
four “GTO” elements) hung below it.
Figure 3 - Flying Configuration.

2.1 Load
The working load limit of the rigging frame is 3,000 kg.
It is important to note that each (GTO) element for which this rigging structure has been
designed weighs approximately 96 kg., to which 6 kg. have been added, as a
precautionary measure, to take into consideration additional loads, mainly due to
connecting cables. This means that the number maximum of GTO enclosures that can be
suspended is twenty-four (in fact, 24 * (96 + 6) = 2448 kg ≈2450 kg ≈24500 N) with a
margin of 550 kg in order to take into consideration any overloading due to the overhang
of the centre of gravity compared to the connection points between the first element and
the frame, particularly when using more than twenty elements).
It must be noted that the aforementioned values regard conditions in which there are no
lateral forces, such as wind, for example. In the event of such forces’ action, they must
be prevented from creating further load on the structure, or they will reduce the safety
factor. In this case, it is advisable to use dedicated stay wires to hold the system still.

4 ACOUSTIC PREDICTION AND MECHANISM
The vertical pointing of the array is adjustable: The splay angle between the elements is
set according to the acoustic coverage needs of the area(s) in question. These
predictions must only be carried out with the Outline OpenArray
TM
simulation software.
It is possible to proceed with the assembly of the system only after checking the
mechanical suitability of the configuration chosen and scrupulously following the precise
indications provided in this manual. Staff members involved will be responsible for
checking the compliance of the installation with the mechanical simulation carried out.

5 FRAME-ELEMENT POSITIONING SEQUENCE
The following is a description of the stages regarding the array assembly
5.1 Arrival
The enclosures are stacked in batches of three and moved on a trolley fitted to the
bottom element by means of two pins (one in the centre of each short side).
Figure 8 – Group of three enclosures, stacked for handling and storage
The frame, according to needs, can be transported separately (in a flight-case) or left
connected to the first enclosure of a “batch” of three GTO (the trolley has the necessary
dimensions to support the weight of this configuration).

USER’S MANUAL FOR MAINTENANCE, CONTROL & INSTALLATION OF THE
“OUTLINE GTO ARRAY” – Translation of the original instructions
Page 13/31
5.2 Assembly and positioning of the frame
The frame can be used in two different configurations, according to the position of the
entire system’s centre of gravity. This enables to achieve wider aiming angles and have a
more even load distribution between the two motors (the choice is made according to the
indications provided by OpenArray
TM
). The “front” configuration (with the cantilever arm
pointing forward) is normally used when the array must be inclined upwards, otherwise
the opposite configuration (called “rear”, with the arm pointing backwards) can be used.
To pass from one configuration to the other, just rotate the frame.
Figure 9 - Array, configuration of the frame with the arm pointing forwards (left)
and backwards (right).
To fix the frame to the first element of the array, proceed as follows:
1. prepare the frame in working configuration, i.e.:
1.a. withdraw the top locking pin;
1.b. rotate the oscillating arm and position it on-axis compared to the centre beam
(working position);
1.c. Fit the locking pin to fix the arm in its working position.

USER’S MANUAL FOR MAINTENANCE, CONTROL & INSTALLATION OF THE
“OUTLINE GTO ARRAY” – Translation of the original instructions
Page 14/31
2. hook the motors on to the frame and raise it by a few centimetres;
3. remove the four connection brackets for the first GTO from their stand-by position
and position them as shown in the following illustration, using the relative locking
pins. Carry out this procedure on both sides.
4. Position the frame above the first element, fitting its nylon feet precisely into place
on the top of the speaker enclosure. Follow the configuration (arm forward or
backward) established at design stage using OpenArray
TM
;

5.3 Preparation and lifting of the first group of
elements and the following ones
All the procedure described is intended as being for batches of three elements
transported on a trolley. Once the frame is positioned and fixed on the first element (see
previous paragraph), proceed as follows:
1. position the module below the motor hoists;
2. set the splay angles between the elements to be flown (excluding the last one):
2.a. position the two front brackets (right and left) so that the cursor is in line with
the required angle;
2.b. insert a pin with locking button in the hole showing the chosen angle;
2.c. insert another locking pin with button in the connection position of the
following element. Carry out this procedure on both sides.
ATTENTION! Check that the settings of the angles on both sides of the system are
identical.
3. withdraw the two rear brackets (right and left) from their stand-by position and turn
them over until they are positioned for connection with the element below
(excluding the bottom element, standing on the trolley);
4. insert the relative pins with locking buttons (one on either side);

USER’S MANUAL FOR MAINTENANCE, CONTROL & INSTALLATION OF THE
“OUTLINE GTO ARRAY” – Translation of the original instructions
Page 17/31
5. raise the group until it is comes off the ground: the enclosures take up position
according to the angles chosen;
6. for each enclosure, insert the two bracing pins (right and left - the ones with no
button) and check again that the settings of the angles on the two sides of each
element are identical; if this is not the case:
6.a. remove only the bracing pins;
6.b. lower the system into stand-by position again;
6.c. repeat steps from 2 to 6, making certain to set the angles correctly.

13. set the splay angle for each element of the next group as described in point 2 (on
both sides);
14. connect the rear bracket as described in points 3 and 4;
15. insert the two bracing pins (one per side) in the first (top) element of the group
standing on the floor;
16. lower the array very slowly, until the two front brackets protruding from the lower
element (set at point 11) fit into the connection positions with the top element of the
group to be lifted;
17. insert the two locking pins with buttons (one on either side);
Attention! The front brackets must be hooked on and braced with locking and
bracing pins on both sides!!!
