Unfortunately, continuous vertical columns are rarely visually acceptable -
particularly where the audience wraps around a thrust stage and sight lines are
critical. In such cases, shorter Longthrow columns may be flown in combination with
Wavefront W8C midfields and downfills.
Martin Audio/M.A.N. Flying System overview
Flown clusters are recommended for very high power music systems covering large
venues to ensure adequate coverage without excessive levels at the front of the venue.
Wavefront series products are fitted with MAN load-certified flying points and are
designed to comply with the 12:1 safety factor specified by the German VBG70
standard when used with compatible 12:1 flying systems.
MAN Transformer or Installer/Tourer flying systems allow columns of loudspeakers
to be assembled by attaching individual loudspeakers to vertically daisy-chained D-
rings using keyhole cabinet fittings - hence the tendency to base flown designs in this
applications guide on multiple columns. The beauty of the MAN system is that each
cabinet in a system supports only its own weight.
Each pair of vertical chains is attached to a single-width, centrally pivoted sub-bar
which, in turn, is attached to a two-way, centrally pivoted flying bar so that the
system “finds its own level”, if accidentally hoisted asymmetrically, avoiding undue
stresses and strains. Please note that all components must have a 12:1 safety factor.
Vertical splay angles are determined by intercabinet chain lengths whilst the overall
column tilt is determined by the length of the chains between the upper cabinet and
the sub-bar. Vertical columns are splayed by tensioning a rachet strap threaded
through the sub-bar and all of the cabinet back plates. Cabinets may be fitted with
rear hinge back plates to allow removable hinges to be slotted in place. These hinge
assemblies provide a more rigid rear cabinet alignment.
