A-Series rigging components
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

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.
