"Echo" Interior Self Amplified Speaker ELK-870
APPLICATION
The ELK-870 is a self amplified interior speaker which may be connected to virtually any audio source,
ie: microphone, radio, computer sound card, telephone PBX or KEY system paging output, etc., even
an ordinary single line phone set. The audio source is amplified up to 10 watts, adjustable from an on-
board volume control. The ELK-870 features a reverse mounted, high quality internal speaker that
effectively echos the sound off the surrounding mounting surface. This arrangement enriches the low
frequency ranges and reduces the undesirable high "tinny" frequencies. The attractive "no-grille"
surface of the ELK-870 may be painted or wallpapered to match the surrounding decor. It is wall or
ceiling mountable. For additional coverage, up to three (3) external 8 Ohm speakers may be wired in
parallel with the internal speaker. The ELK-870 operates on 12 to 24 Volts A.C. or D.C. and requires
only 22-24 gauge telco or alarm type wire.
