Assembling the Power Stand and Array

Before connecting the power
stand to a power source,
assemble the L1 Pro32 using the
upper mid-high array and lower
mid-high array.

1. Insert the lower array into
the power stand.

2. Insert the upper array into
the lower array.

The L1 Pro32 can be used
without the upper array.
This configuration is useful
when a venue ceiling cannot

Setup Scenarios

The L1 Pro32 can be placed on the floor or on an elevated stage (see Assembling the Power
Stand and Array on page 7).

WARNING: Do not place the equipment in an unstable location. The equipment could
become unstable leading to a hazardous condition, which could result in injury.

CAUTION: The power stand should not be placed anywhere that may block the
ventilation holes at the rear/bottom of the L1 Pro32. Operating directly on sand or grass
could cause debris to enter the product through vent openings and result in the L1 Pro32
not functioning properly.
