The CDL12 can be configured as an individual point-source loudspeaker or in a
vertical array with other CDL12 loudspeakers and the CDL18s Subwoofer. Integrated
rigging makes easy and secure box-to-box deployment. When suspending two or
more arrayed CDL-series loudspeakers, PreSonus requires the CDL Rigging Grid. This
separately sold rigging grid allows the suspension up to (6) CDL12 loudspeakers or
up to (5) CDL12 loudspeakers with up to (2) CDL18s subwoofers to be suspended
in a vertical array. For all supported configurations, see the chart in Section 2.6.
Up to two CDL12 loudspeakers maybe be used on a tripod or on a sub pole
over the CDL18s subwoofer (See Section 2.7 for restrictions and guidelines).
The CDL12 is equipped with a two-position pole-mount to provide
more flexible coverage when pole-mounted (0˚ or 10˚ 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 CDL Rigging Grid.
WARNING: The CDL12 weighs 65 lbs. (29.5 kg). The CDL18s weighs 105 lbs.
(47.6 kg) Use proper lifting techniques to avoid serious injury. Please see Section
2.4 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 CDL Rigging Grid.
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-series Loudspeakers
When it's time to power down, your system should be turned off in the reverse order.
CDL-series 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-series loudspeakers are not weatherproof. Protection from the
elements must be provided in outdoor installations.
