Flying Hardware
The ‘A’ system flying bars consist as follows:
• Single bar – supports a vertical column of cabinets up to 8 deep.
• Twin bar – supports two vertical columns up to 8 deep.
• Triple bar – supports three vertical columns from a single pick-up point or with chain
bridles, specifically designed for outdoor use with ground support towers
• Mother beam – used to connect multiples of single bars and/or twin bars in a
modular fashion, allowing the creation of speaker clusters up to and including full
360° arrays.
• Extender beam – connects half a mother beam to a two-wide bar and a single bar,
which can be bridled from one motor or picked up by two points
• Spacer bar – used to join and maintain the distance between flying bars.
Flying boxes in their horizontal format is simply achieved by suspending vertical columns of
loudspeakers using chains attached to lifting points on the fixed angle flybars depicted
below. Based on the predicted 25° of horizontal coverage from a single cabinet, it is an easy
job to assess how many columns, and therefore which particular combination of flybars, will
be needed to achieve the required coverage. The top chains are adjustable to allow the
cluster to hang either close to the bar where trim height is critical, or further away when
more radical kelp is applied to the columns. In addition, all flybar assemblies allow the user
two options to vary the width at the flybar to accommodate deep arrays.
Wide and Narrow Flybar Settings
In order to accommodate the wide range of vertical coverage requirements dictated by a
particular venue, all flybars - except the single bar - offer two sets of lifting points, enclosure
attachment points and lifting strap points. The narrow setting is designed for a column of
cabinets in the ‘A’ or horizontal orientation and will be more than adequate for the majority
of applications. However, the wide setting provides the additional horizontal spacing at the
flybar to allow for a vertical column of up to eight cabinets deep to be flown where more
vertical coverage is called for. No additional parts or flybars are required to accommodate
virtually all situations; it can all be achieved using only one type of flybar.
