Figure 1a: ELX112 / ELX115 Optimum Coverage (Front View) Figure 1b: ELX112 / ELX115 Optimum Coverage (Side View) Electro-Voice Live X Series Passive Owner's Manual 5 Tripod and Floor Monitor Operation Tripod Electro-Voice ELX112 and ELX115 loudspeakers include 35mm (1-3/8") stand mounts to allow mounting on tripod stands or above an ELX118. 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. Secure cables with wire ties or tape whenever possible. · Do not attempt to suspend more than one speaker on a stand designed for a single speaker. · Unless you are confident that you can safely handle lifting the weight of the speaker onto the stand, ask another person to help you place it.
