2.1 Locking pins
WARNING!
Potential risk of personal injury and/or
damage to material!
The steel wires of the Locking pins are not intended to carry any
load. The cabinet's weight must only be carried by the Front and
Splay/Rear links in conjunction with the front and rear rigging
strands of the loudspeaker cabinets and the rigging components.
Ensure all Locking pins are fully inserted and securely locked
before lifting any load.
The A-Series loudspeaker cabinets and rigging components are
equipped with a Locking pin 5 x 35 mm.
Note: The Locking pins are undetachably attached to the
different rigging components on the cabinet using steel wires.
Throughout this manual these steel wires are not shown in the
corresponding illustrations.
Functionality (Quick lock mechanism)
Proceed as follows:
1. Press the button to release the locking mechanism ( [r]).
2. Remove the Locking pin through the respective link or socket.
3. Insert the Locking pin through the respective link or socket until
it is fixed in place.
4. Release the button to lock the pin ( [l]).
5. Recheck the Locking pin is securely locked by briefly pulling
the Locking pin towards you.

2.2 Ring cotter
In connection with the A-Series rigging system, ring cotters are used
for the following items to prevent the respective item from
slackening and/or loosening:
▪ Fixing bolt of the base plate splay link.
▪ Fixing bolt of the cabinet's splay link.
Function of the ring cotter
By default, the ring cotters are "locked" to prevent them from
loosening.
For modification reasons such as altering the position of the
Frame's Rear link or exchanging a shackle, it may be necessary to
temporarily remove the ring cotter and reattach it afterwards.
For this purpose proceed as follows:
1. Unlock
Unlock the ring cotter by pushing up the front wire loop over
the straight wire shaft.
2. Release and remove
Push down the rear wire loop until the ring cotter snaps over
the edge of the bolt and remove the ring cotter.
3. Refit and lock
Refit the ring cotter by pushing the straight wire shaft through
the hole and pressing the front wire loop underneath the
straight wire shaft.

2.3 Cabinet rigging mechanism
The cabinets are mechanically connected to the Flying frame and
subsequent loudspeakers using the Front links on both sides of the
cabinet front and the central Splay link on the rear rigging strand
of the cabinet.
All necessary rigging components are mounted to the cabinet and
slide out or fold out when needed.
2.3.1 Front link mechanism
To extend and/or park the Front link, proceed as follows:
1. Slide out the Front link [1] up to its stop position.
↳Once the Front link is fully extended, it will be automatically
fixed in place by the spring steel sheet [2].
2. To slide the Front link back into its park position, press the
spring steel sheet towards the front grill.
3. Slide the Front link back into its park position.
2.3.2 Splay link mechanism
The Splay link is fixed in its park position ( ) by a Locking pin.
1. Release the Locking pin and fold out the Splay link.
2. To park the Splay link, proceed in reverse order and ensure
the extension tube is fully pushed in and the head is aligned
correspondingly, as shown in the graphic opposite.

2.3.3 Setting the splay angle(s)
Splay angles between adjacent cabinets can be set in the range
from 20° to 40° in 5° increments resulting in a total coverage of
50° up to 70° for two cabinets, with a maximum total coverage of
150° for four cabinets.
Splay angles can also be set symmetrically or asymmetrically,
depending on the application.
For this purpose, the Splay link provides two different lengths:
Standard or Extended.
Together with the corresponding Hole grid on the rear rigging
strand, the desired splay angles can be set in the range from 20°
to 40° in 5° increments.
The Splay link is constructed as a cylindrical extender (we call it
the 'Trombone';).
The extension tube head can be turned counter clockwise by 90°
and back again.
To change between the Standard and Extended positions, proceed
as follows:
Standard length
1. Fold out the Splay link as previously described.
2. Turn the extension tube head counter clockwise by 90° to fix
the standard length of the Splay link.
Extended length
1. Fold out the Splay link as previously described.
2. Pull out the extension tube to its stop position.
3. Turn the extension tube head counter clockwise by 90° to fix
the extended length of the Splay link.
Standard | Extended | Hole grid
Splay link lengths and correlation to the hole grid on the rear rigging strand.

A-Series rigging components
2.3.4 Splay link of the Base plate
The rear rigging slot of the Base plate is also equipped with a
Splay link. Depending on its position in the hole grid of the rigging
slot and on its set length (Standard or Extended), the Splay link
allows either an uptilt or a downtilt of the first cabinet.
Up In combination with the 35° hole on the rear rigging
strand of the first cabinet and with the Splay link set to
'Standard' length, the rigging slot of the Base plate
allows for uptilt angles of 5° (upper hole), 10° (center
hole) and 15° (bottom hole).
Down In combination with the 20° hole on the rear rigging
strand of the first cabinet and with the Splay link set to
'Extended' length, the rigging slot of the Base plate
allows for downtilt angles of –10° (upper hole), –5°
(center hole) and 00° (bottom hole), shown as an
example in the graphic opposite.
The splay angle(s) of the next (two) cabinet(s) is/are set in the
same manner as described in the previous sections.
Changing the Splay link position
To easily change the position of the Splay link of the Base plate, it
is fixed using the corresponding Locking pin.
To change the position of the Splay link, proceed as follows:
1. Release the Locking pin.
2. Move the Splay link to the desired hole position in the rigging
slot.
3. Insert the Locking pin and ensure the pin is fully inserted and
properly locked.

Rigging/derigging
WARNING!
Potential risk of personal injury and/or
damage to material!
Always secure ground stacked setups against movement and
possible tipping over.
Observe the maximum number of cabinets permitted. This is
particularly important when setting up mixed ground stacks.
3.1 Preparing the setup
General
Check the acoustical and mechanical setup using ArrayCalc.
When on site first:
▪ Clear the working areas and ensure there is enough space to
set up the ground stack.
▪ Prepare the cables and link cables according to the number of
amplifier channels and cabinets used.
Inspections before setup
Before setting up the ground stack, carry out a visual inspection of
all system components for faults. This also includes the
loudspeakers and in particular the rigging parts of the cabinets
(Front and Splay/Rear links).
Damaged components must be withdrawn from use immediately.
Please also follow the instructions given in Þ Chapter 4 "Care and
maintenance" on page 15.
3.2 Order of assembly
3.2.1 AL ground stack
1. Prepare the Base plate
1. Fix the Splay link of the Base plate in the required hole
position.
2. Position the Base plate on the ground.
