Assembling the System
L1 Pro8 L1 Pro16
Mid-high array
Array extension
Before connecting the system
to a power source, assemble
the system using the array
extension and mid-high array.
1. Insert the array extension
into the subwoofer power
stand.
2. Insert the mid-high array into
the array extension.
The L1 Pro8/Pro16 can be
assembled without using
the array extension; the
mid-high array can be
connected directly to the
subwoofer power stand. This
configuration is most useful
when on an elevated stage to
be sure the mid-high array is
at ear level.
