User manual ELECTRO-VOICE 421 DATASHEET

[. . . ] Make sure to: · Check the specifications of the speaker stand to be certain it is capable of supporting the weight of the speaker. · Check that the speaker stand is placed on a flat, stable surface and be sure to fully extend the legs of the stand. Do not try to make the stand "taller" and compromise its structural integrity. · Route cables and position the stand so that performers, production crew and audience members will not trip over the stand or cables and pull the speaker system over. [. . . ] · If you intend to hang or fly the Zx3 system, only do so safely with the correct hardware and accessories. WARNING: Suspending any object is potentially dangerous and should only be attempted by individuals who have a thorough knowledge of the techniques and regulations of rigging objects overhead. Electro-Voice® strongly recommends that Zx3 speakers be suspended taking into account all current national, federal, state and local regulations. It is the responsibility of the installer to ensure that Zx3 speakers are safely installed in accordance with all such regulations. If Zx3 speakers are suspended, Electro-Voice® strongly recommends that the system be inspected at least once a year. If any sign of weakness or damage is detected, remedial action should be taken immediately. There are data sheets for each EV Suspension and Array Kit that should also be consulted prior to suspending speakers. · Electro-Voice® does not recommend use of Zx3 speakers outdoors in direct exposure environments. · Electro-Voice® Zx3 loudspeakers are easily capable of generating sound pressure levels sufficient to cause permanent hearing damage to anyone within normal coverage distance. Caution should be taken to avoid prolonged exposure to sound pressure levels exceeding 90 dB.

For best paint adhesion, we recommend a "Plastic Adhesion Promoter" be applied before any paint. Sherwin Williams Plastic Adhesion Promoter UP07226 is a good example (See Telex document number LIT000066-000 for further details. ) Once Plastic Adhesion Promoter is applied follow the manufacturer's painting directions as you would normally. Painting a Zx3 Grille Remove grille from loudspeaker and remove the backing material & logo from grille prior to painting. [. . . ]
