FLYING HARDWARE
The Aspect TA-880 flying system consists as follows:
• Flying swords and safety lynch-pins – support a single cabinet.
• Flying chains – link the top row to flybars.
• Twin bar – supports two vertical columns.
• Triple bar – supports three vertical columns
• Chain bridles for twin and triple bars
The flying system is based around the use of removeable flying swords which pass through
slots machined in the enclosure and are held captive by safety linch-pins through holes in the
swords, locating into load-rated metal fixings incorporated into the handle boxes. The flying
system eliminates the need for costly integral flying hardware, thereby not penalising those
users who exclusiv ely ground stack and therefore have no flying requirements.
Horizontal Coverage
Because the Polyhorn’s design dramatically reduces the acoustic energy outside of the
specified 25° horizontal dispersion pattern, it is recommended that Aspect TA-880 enclosures
always be arrayed in a smooth even curve, resulting in an array angle of 25° between boxes.
Based on this assumption 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.
The following table illustrates how many columns of loudspeakers and which flybars should
be used to achieve a given horizontal coverage.
Required Horizontal Coverage Number of Colums Flybar
25° Single column N/A
50° Two columns FB-880/2W
75° Three columns FB-880/3W
