Ceiling loudspeaker designed for indoor
playback of music and speech, especially fit
for mounting on ceilings or walls, e. g. in
offices, restaurants, classrooms, waiting
rooms and corridors. The ARS 5624 (ARS 5628)
consists of an elliptic direct radiating
electro-dynamic speaker, an impedance-matching
transformer, and two-piece non-flammable
plastic housing. The loudspeaker carrying the
transformer is fixed with four screw to the
upper cover which forms a sound-permeable
grid. This assembly is fixed with four screws
to the lower cover which is designed for
mounting in the desired place. The speaker
connects to the 100 V line distribution
system. The rated power input may be selected
in accordance with the volume required by
reconnecting the input wire onto the
corresponding branch of the impedance-matching
transformer. The power input of the speaker is
set to the maximum by the manufacturer (6 W/3
W).
