APPLICATIONS

The SD72WV is an aggressively priced, high quality speaker/baffle

transformer package with center mounted volume control suitable for

most any paging or background application including retail stores,

restaurants, schools and other institutional facilities. Easy-to-adjust

knob style potentiometer sets output level so that audio may be heard

optimally in work centers with fluctuating ambient noise, including multi-

task areas, individual offices, departments and conference areas.

Models feature a baffle mounted volume control knob, which can be

removed to protect sound level settings from tampering and/or for aes-

thetic preference.

GENERAL DESCRIPTION

The speaker used in the SD72WV is the next generation of Atlas high

performance cone loudspeakers, very similar to the preceding C-Series

speakers. The similarity in the sonic qualities ensures that contractors

and designers who have worked with the Atlas Sound C-Series in the

past will know exactly what to expect when they use the SD72WV.

Model SD72WV is a dual cone, 25 watt 8" (205mm) loudspeaker with a

10oz. (260g) ceramic magnet. It includes a curvelinear, treated paper

cone for lower harmonic distortion. The loudspeaker is also equipped

with a full 1" diameter copper voice coil with a black anodized aluminum

former for better power dissipation. Model SD72WV operates within a

frequency response range of 45Hz-19kHz (nominal) with a sensitivity

of 97dB and a dispersion angle of 105°. Package includes factory

installed 25/70.7V line matching transformer with tap selections ranging

from .25 to 5 watts. The SD72WV includes a factory installed CRS

baffle with concealed loudspeaker mounting studs and includes screw

mount hardware. The SD72WV baffle features standard mounting holes

to accommodate the majority of Atlas Sound 8" tile bridges, mounting

rings and enclosures. When specifying mounting hardware be advised

that the dimensions of the SD72WV baffle match the Atlas Sound

Model 62-8. The baffle finish is white powder coat epoxy. The baffle

mounted volume control has a 5 watt audio rating and is factory wired

to the voice coil. Units are shipped assembled, ready for installation.
