GROUND STACKING LAs118
v2
Ground stacking of any loudspeaker enclosure is normally an intuitive process. But when talking about the
LAs118
v2
, although it is still intuitive, there are a few things to take into consideration. The first is that when packed
together like in the image above, they shouldn’t be placed touching each other. There should be a gap of at least
2 or 3 mm between vertical stacks to avoid noises due to contact induced by vibration. Another important piece of
knowledge is that when ground stacking you should not connect them using the rigging frame structures. The
locking mechanism on the sliding arms is not just to keep the arms in place. It also produces a dampening effect
on the metal parts and helps to greatly reduce vibration noises created due to the allowance on the sliding arms.
CARDIOID PATTERN SETUP
A cardioid response stack is a configuration where there is a direct
radiating element and an indirect radiating element, placed and configured
in a way that while increasing SPL in the venue, decreases it in the stage
area through destructive interference. It is becoming a very popular
configuration, because when properly configured, it almost completely
eliminates the bass at the back of the system. The development of the
LAs118
v2
had this principle in mind from the beginning, and has a few
features that make it a perfect choice for this purpose. Among those, are
the universal feet that allow engagement of the LAs118
v2
both in traditional
and cardioid stacks.
The preset must be adjusted to have the proper cardioid behaviour.
