PLACEMENT
The SA1521z speaker is designed to sit on the floor or
stage. It can be pole-mounted via the built-in socket on
the bottom of the cabinet. Be sure the pole is capable of
supporting the weight of the SA1521z.
WARNING: The cabinet has no rig-
ging points and is not suitable for
rigging. NEVER attempt to suspend
the SA1521z by its handles.
You can create a horizontal array by placing the cabinets
side-by-side. However, you should have a good understand-
ing of the relationship between the splay angle (the angle
between the facing sides of the cabinets), the on-axis
power, and frequency cancellation effects between cabinets.
Whentwocabinetsareplacedside-by-side,theactual
splay angle is 20º (determined by a 10º angle on each
cabinet side). As the splay angle increases toward the
angleofhorizontalcoverage(90ºfortheSA1521z),the
on-axis power decreases, but the frequency response be-
comes smoother as the comb-filtering effects (caused by
the interaction in the area of double-coverage) decrease.
As with any powered components,
protect them from moisture. If you
are setting them up outdoors, make
sure they are under cover if you
expect rain.
