3 Application and Deployment
CDL loudspeakers can be configured as an individual point-source loudspeaker or in
a vertical array with other CDL loudspeakers of the same model. Integrated rigging
makes easy and secure box-to-box deployment. When suspending two or more
arrayed loudspeakers, PreSonus requires the CDL Rigging Grid engineered for your
loudspeaker model. This separately sold rigging grid allows the suspension up to
(6) CDL loudspeakers. For all supported configurations, see the chart in Section3.6.
Up to two CDL loudspeakers may be used on a tripod or on a sub pole over
a CDL subwoofer. A single CDL loudspeaker may also be mounted atop a
ULT18, or AIR18 subwoofer (See Section 3.7 for restrictions and guidelines).
The CDL loudspeakers are equipped with a two-position pole-mount to
provide more flexible coverage when pole-mounted (0˚ or 7.5˚ downward).
IMPORTANT: In all cases, when rigging loudspeakers together, attach the
bottommost unit to the loudspeaker directly above it, moving up the grid
to the topmost unit, ending with the model specific Rigging Grid.
WARNING: The CD L12P weighs 63 lbs. (28.6 kg). The CDL 10P
weighs 55.1 lbs (25 kg) .Use proper lifting techniques to avoid serious
injury. Please see Section 2.6 for Maximum Suspended Load.
WARNING: When assembling or disassembling arrayed
loudspeakers, make sure that all components are properly
supported throughout the entire process to avoid damage or injury.
WARNING: To ensure secure latching, verify that the loudspeakers are
properly aligned for box-to-box vertical arraying. If loudspeakers are not
properly aligned, physical damage, and personal injury may occur. The top of each
loudspeaker should be parallel to the bottom of the unit above it. For suspension, the
topmost unit must be securely attached to the CDL12P or CDL10P Rigging Grid.
3.1 Getting Started
Before you begin, here are a few general rules of thumb:
• Always make sure your loudspeakers are powered off when making connections.
• Do not allow your inputs to clip. Watch the Clip LED on the back of your
loudspeaker. When this LED illuminates, it indicates that the analog-
to-digital converters are in danger of being overdriven. Overdriving
the converters causes digital distortion, which sounds terrible.
Your PA and attached equipment should be powered on in the following order:
1. Sound sources (keyboards, D.I. boxes, etc.) connected to your mixer
2. Mixer
3. CDL Loudspeakers
When it’s time to power down, your system should be turned off in the reverse order.
3.2 Cooling
CDL loudspeakers are internally-powered. As such, they utilize a power amplifier
that produces heat. Allow a minimum of 6” (152.4 mm) clearance at the rear of the
enclosure for cooling. Do not restrict airflow to the rear of the speaker enclosure.
CAUTION: To avoid overheating, do not install enclosures with the amplifier
panels exposed to direct sunlight. This can heat the amplifier module and
reduce performance. Install sunshades to avoid direct exposure. The maximum
ambient temperature for full performance should not exceed 104˚ F (40˚ C).
CAUTION: Do not install enclosures where they will be exposed to rain
or other moisture. CDL loudspeakers are not weatherproof. Protection
from the elements must be provided in outdoor installations.
