TTL33-A GROUND STACKING
The mechanical design of the suspension system allows the TTL33A
system to be either fl own or ground stacked. Either method requires
the array frame, the FLY BAR TTL33A.
Even the smallest of arrays benefi t from a careful review of what
vertical coverage is being created, and how that affects the liste-
ning environment. Typically, four TTL33A enclosures is the minimum
practical array format if controlled coverage and precise directivity is
a system design criteria for an event.
The fi gure below shows a ground stack of four boxes with a mild
baffl e arc setting on TT+ subs.
This array solution can be expected to provide controlled directivity.
This type of compact array can work well in small venues, including
concert clubs and smaller auditoriums.
In addition to its fl own capabilities, the FLY BAR TTL33A frame forms a secure base for ground-stacking having rubber feet
already installed.
For ground-stacking are necessary optional STCK BAR TTL33A rigging frames and additional quick release pins.
