4 – CIS63. INSTALLATIONThe metal bracket provided with each loudspeaker offers quick installation into ceilings.WARNING: Make sure that the loudspeaker is installed in a stable and secureway in order to avoid any conditions that may be dangerous for persons or structures:• Check to make sure that the ceiling has the necessary mechanical characteristics tosupport the weight of the loudspeaker without the danger of it falling.• Before suspending the loudspeaker, carefully check all the components to be used tomake sure there is no damage, deformation, corrosion and/or missing or damagedparts that could reduce the safety of the installation.Installation precautions• Use speaker cables with an adequate cross-section (gauge). The greater the distancebetween the amplifier and loudspeaker, the larger the connection cable cross-sectionshould be.• To prevent inductive phenomena causing humming or distortion, the speaker cablesshould not be run together with electrical energy conductors, microphone cables,or line-level audio lines. Use speaker cables that have markings to distinguish thepolarity, such as insulation or conductors of different colors.Installation procedure1. Cut a 7.87” (200 mm) hole in the ceiling, using all safety precautions to avoid cuttingpower lines, water lines etc.2. Take the bracket, loosen the twowing bolts, and slide the fixing platesupwards. Press the bracket up into theceiling hole.3. When the bracket is securely pushed up inside thehole, slide the fixing plates down to grip the topsurface of the ceiling.
