Electro-Voice Plasma Series manual Suspending Plasma P1 Speaker Systems

Suspending Plasma P1 Speaker Systems

P1 enclosures have L-track located on the top, bottom, and on one side. Single or double stud ring fittings can be attached to the L-track to be used as suspension points. These points are located at the center of gravity to allow the system to hang straight when used either vertically, or horizontally. Plasma P1 is NOT designed to be suspended vertically from one another. More than one system should never be suspended from a single point! Working load limits for the enclosure, and fittings are shown below in Figure 5. Plasma P1 enclosures have been pull tested and exceed a safety factor of 10 to 1.

Prior to each use, inspect the grid assembly or suspension point(s) and associated hardware for any cracks, deformations, broken welds, corrosion, missing or damaged components which could reduce the grid assembly or suspension point(s) strength. Replace any damaged hardware. Never exceed the limitations or maximum recommended load intended for grid assembly design or suspension point(s). As an added safety measure, it is suggested that the user install a second suspension point back to the grid (or building structural supports). This redundant safety point should have as little slack as possible (less than one inch is preferable).

Prior to each use, inspect the loudspeaker enclosures for any cracks, deformations, missing or damaged components, which could reduce enclosure strength. Inspect the track and bracket assembly on the enclosures for any cracks, deformations, missing or loose screws which could reduce the flying hardware strength. Replace any loudspeaker systems that are damaged or missing hardware. Never exceed the limitations or maximum recommended load for the Plasma systems.
