LB3 Premium Cabinet Loudspeakers LB3-PC2, LB3-PC3, LM1-MBx12/1 en Installation note
LB3 Premium Cabinet Loudspeakers Important safeguards en 3 1 Important safeguards Always mount the loudspeakers securely with the recommended bracket(s). If a generic bracket is used, use the inserts with the load distributed in the same way as with the recommended bracket. Only use the pole mount vertically with a maximum deflection of the vertical of 2 degrees. Do not place a heat source or an open flame on or near the loudspeaker. The mounting materials marked with an asterisk (*) in the drawings are not supplied, but are generally available in your local hardware store. Make sure that the minimum tensile strength of these mounting materials (e.g. suspension chain, suspension cable, safety cord and shackle[s]) is 1, N/mm2. Always use a safety tether/ safety cord.
