Integrated Suspension Points (suspended installations)
The K8, K10 and K12 enclosures each feature three load-rated M10 installation points.
As shipped from the factory, each pick point has a rubber plug installed to retain the sleek look of the enclosure. These installation points are designed
for use with the eyebolts included in the available accessory kit, model number K SERIES M10 KIT. The installation points may also be used with any
forged shoulder eyebolt with an M10 thread, provided the length of the thread is no more than 0.8 inch (20 mm).
Ensure all pick-point fasteners are installed and correctly tightened in order to maintain enclosure’s rated strength. Use either
QSC’s M10 forged shoulder eye bolts contained in K SERIES M10 KIT or an M10 forged shoulder eyebolt with a thread length no more
than 0.8 inch (20 mm). Contact QSC Technical Services department for complete information.
Cooling in Installed Applications
This is a self-powered loudspeaker containing an internal power amplifier that produces heat. Allow a minimum of 6" (152 mm) clearance at cabinet
back for convection cooling. Keep anything that might restrict airflow away from the rear of the enclosure (i.e draperies, fabric, etc...).
Do not install enclosures with their rear panels exposed to direct sunlight. Direct sunlight will heat the amplifier module and reduce
its ability to produce full output. Install sunshades if the application merits. Maximum ambient temperature for full performance to
specification is 50° C (122° F). Do not install enclosures where exposed to rain or other water sources. The enclosure is not weatherproof.
Outdoor installations must provide protection from the elements.
