Ceiling speaker 

ARS-130-01/100

Ceiling loudspeaker designed to playback music and speech inside buildings, e.g. in offices, classrooms,corridors, etc.
The loudspeaker is designed to be built into ceilings, soffits or possibly on lateral walls and to be connected to the 100 V line distribution.
The rated power input may be selected in accordance to the volume required by connecting the wire from the loudspeaker onto the corresponding branch of the impedance-matching transformer. The power input is set to 6 W by the manufacturer.
The basis of the ceiling loudspeaker is created by a direct radiator electrodynamic loudspeaker Ø 130 mm with high sensitivity and a wide frequency range. The loudspeaker is fastened between a sound-permeable grating and the baseplate fitted with the impedance-matching transformer and threesprings for attachment in the installation hole. The grating and the baseplate are metal-made, surface treated with wite enamel.
